Laravel Eloquent: Mastering the Art of Database Interactions

Laravel Eloquent is an Object-Relational Mapping (ORM) layer that comes built-in with the Laravel framework. It serves as an abstraction layer that allows developers to interact with databases using PHP objects and classes, rather than writing raw SQL queries. Eloquent simplifies the process of retrieving, inserting, updating, and deleting data from the database, making it more efficient and less error-prone.

One of the key features of Eloquent is its ability to represent database tables as models. Models are PHP classes that correspond to database tables, and each instance of a model represents a row in that table. Eloquent provides a set of methods and conventions that allow developers to define relationships between models, such as one-to-one, one-to-many, and many-to-many relationships.

Mastering the art of database interactions with Eloquent involves understanding the following concepts:

1. Model Definition: Creating models that correspond to database tables, defining table names, primary keys, and other properties.

2. Retrieving Data: Using Eloquent's query builder to fetch data from the database, including techniques like eager loading, chunking, and scoping.

3. Inserting and Updating Data: Creating new records, updating existing records, and handling mass assignment protection.

4. Relationships: Defining and working with one-to-one, one-to-many, and many-to-many relationships between models.

5. Eloquent Events: Handling events such as model creation, updating, and deleting, to perform additional logic or data manipulation.

6. Query Scopes: Defining reusable query constraints to simplify complex queries.

7. Accessors and Mutators: Customizing how Eloquent retrieves and stores data in the database, allowing for data transformation and formatting.

8. Eloquent Collections: Working with collections of models, and utilizing the collection's powerful methods for data manipulation and transformation.

9. Database Migrations: Using Laravel's migration system to create and manage database schema changes in a controlled and versioned manner.

10. Eloquent Serialization: Converting Eloquent models to and from various formats, such as JSON or arrays, for data transfer or storage.

By mastering these concepts, developers can leverage the power of Eloquent to build robust and scalable applications with efficient database interactions. Eloquent not only simplifies database operations but also promotes code organization, maintainability, and testability.

In Laravel, Eloquent models serve as the bridge between your application's logic and the underlying database. Each model corresponds to a specific database table, representing its structure and facilitating interactions with the records stored within that table.

Eloquent Model Structure

An Eloquent model is a PHP class that extends the base `Illuminate\Database\Eloquent\Model` class provided by Laravel. This base class provides a wide range of functionality for interacting with the database, including methods for creating, reading, updating, and deleting records.

Within an Eloquent model, you define the properties and relationships that correspond to the columns and associations of the respective database table. This includes specifying the table name, primary key, timestamps, and any additional attributes or behaviors specific to that model.

Defining Database Table Attributes

One of the primary responsibilities of an Eloquent model is to define the structure of the corresponding database table. This includes specifying the table name, primary key, and any other relevant attributes.

By default, Laravel follows a convention where the model name is singular, and the corresponding table name is the plural form of the model name. For example, a model named `User` would map to a table named `users`. However, you can override this convention by explicitly defining the table name within the model.

Models also define any timestamps columns (e.g., `created_at` and `updated_at`) and specify the primary key column if it differs from the default `id`.

Encapsulating Database Interactions

Eloquent models encapsulate all interactions with the database table they represent. This includes creating new records, retrieving existing records, updating records, and deleting records.

Instead of writing raw SQL queries, developers can leverage Eloquent's fluent interface, which provides a set of expressive methods for performing database operations. These methods allow you to build complex queries in a concise and readable manner, reducing the risk of SQL injection vulnerabilities and promoting code maintainability.

For example, to retrieve all records from a table, you can simply call the `all()` method on the corresponding model. To create a new record, you instantiate the model, set its properties, and call the `save()` method. Eloquent handles the underlying SQL statements and database interactions transparently.

Defining Model Relationships

Another crucial aspect of Eloquent models is the ability to define relationships between different database tables. Laravel supports various types of relationships, including one-to-one, one-to-many, and many-to-many.

By defining these relationships within the models, you can easily access and manipulate related data without writing complex join queries. Eloquent provides methods for eager loading related data, reducing the need for multiple database queries and improving performance.

Overall, Eloquent models serve as the backbone of database interactions in Laravel applications. They encapsulate the structure and behavior of database tables, facilitate database operations through a fluent interface, and enable the definition of relationships between tables. By leveraging Eloquent models, developers can write more maintainable and expressive code while reducing the risk of SQL injection vulnerabilities and promoting code organization.

CRUD (Create, Read, Update, Delete) operations are the fundamental actions that allow you to manage data in a database. Laravel's Eloquent ORM provides a set of methods that simplify these operations, making it easy to interact with database records without writing raw SQL queries.

Create

Eloquent provides several methods to create new records in the database. The most commonly used method is `create`, which accepts an array of key-value pairs representing the columns and their respective values. Eloquent handles the insertion of the new record into the database table.

Additionally, you can instantiate a new model instance, set its properties, and then call the `save` method to persist the record in the database.

Read

Retrieving data from the database is a common operation, and Eloquent offers a variety of methods to fetch records. The `all` method retrieves all records from the database table associated with the model. You can also use the `find` method to retrieve a single record by its primary key value.

Eloquent allows you to build complex queries using its fluent query builder, enabling you to filter, sort, and apply constraints to the retrieved data based on your application's requirements.

Update

Updating existing records in the database is straightforward with Eloquent. You can retrieve an existing record using methods like `find` or `findOrFail`, modify its properties, and then call the `save` method to persist the changes to the database.

Alternatively, you can use the `update` method to update one or more records in the database based on specific conditions. This method accepts an array of key-value pairs representing the columns and their new values, along with a condition specifying which records should be updated.

Delete

Deleting records from the database is handled by the `delete` method in Eloquent. You can retrieve a specific record using methods like `find` or `findOrFail` and then call the `delete` method on that instance to remove it from the database.

Eloquent also provides the `destroy` method, which allows you to delete one or more records based on their primary key values or specific conditions.

In addition to these fundamental CRUD operations, Eloquent offers several other methods and features that enhance database interactions. These include:

1. Relationships: Eloquent allows you to define and work with relationships between models, such as one-to-one, one-to-many, and many-to-many relationships, simplifying the retrieval and manipulation of related data.

2. Accessors and Mutators: These allow you to customize how Eloquent retrieves and stores data in the database, enabling data transformation and formatting.

3. Scopes: Scopes provide a way to define reusable query constraints, making it easier to build complex queries across your application.

4. Events: Eloquent provides a set of events that you can hook into, allowing you to perform additional logic or data manipulation before or after various database operations.

By leveraging Eloquent's methods and features for CRUD operations, developers can write more concise and expressive code while reducing the risk of SQL injection vulnerabilities and promoting code maintainability.

In relational databases, tables often have relationships with one another. For example, a blog post may have many comments, or a user may have multiple addresses. Laravel's Eloquent ORM provides a convenient way to define and work with these relationships between models, making it easier to retrieve and manipulate related data.

One-to-One Relationships

A one-to-one relationship is a type of relationship where one record in a table is associated with a single record in another table. For example, a `User` model might have a one-to-one relationship with an `Address` model, where each user has a single address associated with them.

In Eloquent, you can define a one-to-one relationship using methods like `hasOne` and `belongsTo`. These methods allow you to specify the related model and the foreign key column that links the two tables together.

One-to-Many Relationships

A one-to-many relationship is a type of relationship where a single record in one table can be associated with multiple records in another table. For example, a `User` model might have a one-to-many relationship with a `Post` model, where each user can have multiple blog posts.

Eloquent provides methods like `hasMany` and `belongsTo` to define one-to-many relationships. The `hasMany` method is used on the parent model (e.g., `User`), while the `belongsTo` method is used on the child model (e.g., `Post`).

Many-to-Many Relationships

A many-to-many relationship is a type of relationship where multiple records in one table can be associated with multiple records in another table. For example, a `User` model might have a many-to-many relationship with a `Role` model, where a user can have multiple roles, and a role can be assigned to multiple users.

In Eloquent, many-to-many relationships are defined using methods like `belongsToMany` on both models involved in the relationship. Additionally, you need to specify an intermediate table (often called a pivot table) that stores the mapping between the two models.

Defining Relationships

Relationships in Eloquent are typically defined within the model classes themselves. For example, in a `User` model, you might define a one-to-many relationship with the `Post` model like this:

```php

class User extends Model

{

public function posts()

{

return $this->hasMany(Post::class);

}

```

And in the `Post` model, you would define the inverse relationship:

```php

class Post extends Model

{

public function user()

{

return $this->belongsTo(User::class);

}

```

Working with Relationships

Once you have defined the relationships between your models, Eloquent provides several methods to interact with related data. For example, you can retrieve a user's posts like this:

```php

$user = User::findOrFail(1);

$posts = $user->posts;

```

You can also create new related records, update existing related records, and remove related records using Eloquent's relationship methods.

Eloquent relationships make it easier to work with related data in your application, reducing the need for complex join queries and promoting code organization and maintainability.

Query Scopes are a powerful feature in Eloquent that allow developers to encapsulate and reuse common query constraints or modifications. They provide a way to define reusable query logic that can be easily applied to Eloquent queries, enhancing code readability, maintainability, and reducing duplication.

What are Query Scopes?

Query Scopes are essentially methods defined within an Eloquent model that add additional constraints or modifications to the query builder instance. These methods can be chained together with other Eloquent query builder methods, allowing for the creation of complex and expressive queries.

There are two types of Query Scopes in Eloquent:

1. Local Scopes: These are scopes defined within a specific Eloquent model and can only be used with that model.

2. Global Scopes: These are scopes that are applied to all queries for a given model, regardless of where the query is constructed.

Benefits of Query Scopes

Query Scopes provide several benefits that enhance the development experience and code quality:

1. Reusability: By encapsulating common query logic into scopes, developers can easily reuse these scopes across different parts of their application, reducing code duplication.

2. Readability: Well-named scopes make queries more self-documenting and easier to understand, improving code readability and maintainability.

3. Testability: Since scopes are defined as methods within the Eloquent model, they can be easily unit tested, ensuring the correctness of the query logic.

4. Abstraction: Scopes abstract away complex query logic, allowing developers to focus on the higher-level application logic.

Using Query Scopes

To define a local scope, you create a method within your Eloquent model that returns an instance of the query builder with the desired constraints or modifications applied. For example, you might define a scope to retrieve only active users like this:

```php

class User extends Model

{

public function scopeActive($query)

{

return $query->where('active', true);

}

```

You can then use this scope when querying for users:

```php

$activeUsers = User::active()->get();

```

Global scopes, on the other hand, are defined using the `addGlobalScope` method within the `boot` method of your Eloquent model. These scopes are automatically applied to all queries for that model.

```php

class User extends Model

{

protected static function boot()

{

parent::boot();

static::addGlobalScope('active', function ($query) {

$query->where('active', true);

});

}

```

In addition to defining custom scopes, Eloquent also provides several built-in scopes, such as `whereKey`, `whereKeyNot`, and `latest`, among others.

By leveraging Query Scopes, developers can create more readable, maintainable, and testable code while reducing duplication and promoting code organization within their Laravel applications.

In Laravel, when you retrieve data from the database using Eloquent, the results are returned as instances of the `Illuminate\Database\Eloquent\Collection` class. Eloquent Collections are powerful data structures that provide a rich set of methods for working with and manipulating the retrieved data.

What are Eloquent Collections?

Eloquent Collections are Laravel's implementation of the collection data structure, designed to store and manipulate collections of related objects or items, such as Eloquent models or arrays. They serve as a wrapper around the underlying data, providing a consistent and intuitive interface for interacting with that data.

Benefits of Eloquent Collections

Working with Eloquent Collections offers several advantages:

1. Fluent Interface: Collections provide a fluent interface with a wide range of methods for manipulating and transforming data, making it easy to chain multiple operations together.

2. Immutable Data: Collections are immutable, meaning that when you perform an operation on a collection, a new instance is returned, leaving the original collection unchanged. This helps prevent unintended side effects and promotes functional programming patterns.

3. Lazy Loading: Collections support lazy loading, which means that data transformations or operations are not applied until the collection is actually used or iterated over. This can lead to significant performance improvements, especially when working with large datasets.

4. Type Safety: Collections enforce type safety, ensuring that only objects of the same type are stored and manipulated within a given collection.

5. Consistency: Eloquent Collections provide a consistent interface for working with data, regardless of the source (e.g., database queries, arrays, or other collections).

Working with Eloquent Collections

Eloquent Collections offer a wide range of methods for manipulating and transforming data. Here are some common operations you can perform on collections:

Filtering: You can use methods like `filter`, `where`, `reject`, and `whereIn` to filter the items in a collection based on specific conditions or criteria.

Mapping and Transforming: Methods like `map`, `transform`, `flatMap`, and `flatten` allow you to apply transformations or operations to each item in the collection, returning a new collection with the transformed data.

Reducing and Aggregating: You can use methods like `reduce`, `sum`, `avg`, and `max` to perform aggregations or reductions on the data in the collection.

Sorting and Reordering: Collections provide methods like `sort`, `sortBy`, and `sortByDesc` for sorting and reordering the items based on specific criteria.

Retrieving and Checking: Methods like `first`, `last`, `contains`, and `isEmpty` allow you to retrieve specific items or check for the existence of items in the collection.

Eloquent Collections also integrate seamlessly with other Laravel features, such as pagination and caching, making it easier to work with large datasets and improve application performance.

By leveraging the power of Eloquent Collections, developers can write more expressive and maintainable code for manipulating and transforming data retrieved from the database, further enhancing the productivity and effectiveness of working with Laravel's Eloquent ORM.

Conclusion:

Laravel Eloquent empowers developers to master the art of database interactions by offering a clean, expressive syntax for working with databases. Its features, from simple CRUD operations to advanced relationships and query scopes, enable developers to build scalable and maintainable applications without sacrificing readability. Eloquent Collections, a powerful data structure, provide a rich set of methods for working with and manipulating retrieved data, making expertise in Collections highly valuable when looking to hire Laravel developers or partnering with a Laravel development company. By embracing Eloquent, Laravel developers can streamline their workflow, focus on creating innovative solutions, and make the database interaction process a joy rather than a challenge, ultimately delivering high-quality, efficient applications.

My Own Blog by Laravel(1)

Make my own blog with Laravel!!

Hi guys, I will make my own blog by Laravel. I'm a Japanese cook in BC. But I don't work now because of COVID-19. So I have much time now. That's why I have started to learn Laravel. I'm not a good English writer. But I will do my best in English. Please correct my English if you would notice any wrong expressions. Thank you!

Anyway, I will post about making a blog by Laravel for a while. Let's get started!

All we have to do

Install Laravel

Create a Project

Database Setting

Migration

Create Models

Seeding

Routing

Make Controllers

Make Views

Agenda

Today's agenda is

Install Laravel

Create a Project

Database Setting

Migration

Create Models

Seeding

Install Laravel

Laravel utilizes Composer to manage its dependencies. So install Composer first if you have not installed Composer yet. Ok, now you can install Laravel using Composer.

% composer global require Laravel/installer

Here we go. So next step is to create a project named blog!

Create a project

Creating a project in Laravel is super easy. Just type a command like below.

% laravel new blog

That's it. So easy. That command bring every dependencies automatically. And you move to blog directory.

% cd blog

Now you can use a new command called 'artisan'. It's a command used for Laravel. For example, you can start server with this command.

% php artisan serve

Do you see command line like this?

% php artisan serve ~/workspace/blog Laravel development server started: http://127.0.0.1:8000 [Mon Apr 20 09:20:56 2020] PHP 7.4.5 Development Server (http://127.0.0.1:8000) started

You can access localhost:8000 to see the Laravel's welcome page! If you want to know the other arguments of artisan, just type like this.

% php artisan list

Then you can see all artisan commands. You can also display the commands for a specific namespace like this.

% php artisan list dusk ~/workspace/blog Laravel Framework 7.6.2 Usage: command [options] [arguments] Options: -h, --help Display this help message -q, --quiet Do not output any message -V, --version Display this application version --ansi Force ANSI output --no-ansi Disable ANSI output -n, --no-interaction Do not ask any interactive question --env[=ENV] The environment the command should run under -v|vv|vvv, --verbose Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug Available commands for the "dusk" namespace: dusk:chrome-driver Install the ChromeDriver binary dusk:component Create a new Dusk component class dusk:fails Run the failing Dusk tests from the last run and stop on failure dusk:install Install Dusk into the application dusk:make Create a new Dusk test class dusk:page Create a new Dusk page class

So let's go to next step!

Database setting

Open .env located under root directory. And edit around DB setting.

DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=blog DB_USERNAME=root DB_PASSWORD=

Depends on your database. I use MySQL and I already create database named blog in MySQL. You should create user for only this project when you deploy.

Migration

Laravel supplies the migration system. It allow you to control database using php code. For example, when you want to create database, type the command like this.

% php artisan make:migration create_posts_table

You can see a new migration file database/migrations/xxxx_xx_xx_xxxxxx_create_posts_table.php. Write down columns you need in the function called up() and write down columns you want to delete in down(). Edit it.

public function up() { Schema::create('posts', function (Blueprint $table) { $table->increments('id'); $table->boolean('published'); $table->string('title'); $table->longText('body'); $table->string('tag')->nullable(); $table->timestamps(); }); }

It's ready! Execute this command.

% php artisan migrate

Here we go! Now you got some tables with columns! Let's check them out in MySQL console.

% mysql -uroot

And check tables and columns.

Good! You could create tables and columns by php. Next step is Create Model.

Create Model

Laravel Framework is MVC application model. MVC is Model, View and Controller. Application works with each role. View works for display to browsers. Controller works as a playmaker. It receives request from router and access databases to get some datas and pass the datas to views. Model connects to the database and gets, inserts, updates or deletes datas.

Now you create a Model.

% php artisan make:model Post

Then you will see the new Post model under app/Post.php.

<?php namespace App; use Illuminate\Database\Eloquent\Model; class Post extends Model { // }

This model has no code. But it's ok. You can leave it for now.

About a model name

A model name is important. A model connects to table of the database with the rule of the name. If you have a posts table, Post model is mapped with posts table automatically.

Seeding

Seeding is very useful function for preparing test datas or master datas. You can use it easily. All you need is just 1. making seeder file and 2. executing it. Let's do that.

Making seeder files

% php artisan make:seeder BooksTableSeeder Seeder created successfully.

Edit seeder files

public function run() { DB::table('posts')->truncate(); $posts = [ [ 'published' => true, 'title' => 'The First Post', 'body' => '1st Lorem ipsum...', 'tag' => 'laravel', 'user_id' => 1 ], [ 'published' => true, 'title' => 'The Second Post', 'body' => '2nd Lorem ipsum dolor sit amet...', 'tag' => 'shiba-inu', 'user_id' => 1 ], [ 'published' => false, 'title' => 'The Third Post', 'body' => '3rd Lorem ipsum dolor sit ...', 'tag' => 'laravel', 'user_id' => 1 ] ]; foreach($posts as $post) { \App\Post::create($post); } }

And edit DatabaseSeeder.php file.

public function run() { // $this->call(UserSeeder::class); $this->call(PostsTableSeeder::class); }

Execute seegding

% php artisan db:seed Seeding: PostsTableSeeder Database seeding completed successfully.

Sweet. Let's check out database.

mysql> select * from posts; +----+-----------+-----------------+-----------------------------------+---------------------------------+---------------------+---------+ | id | published | title | body | tag | created_at | updated_at | user_id | +----+-----------+-----------------+-----------------------------------+-----------+---------------------+---------------------+---------+ | 1 | 1 | The First Post | 1st Lorem ipsum... | laravel | 2020-04-19 19:16:18 | 2020-04-19 19:16:18 | 1 | | 2 | 1 | The Second Post | 2nd Lorem ipsum dolor sit amet... | shiba-inu | 2020-04-19 19:16:18 | 2020-04-19 19:16:18 | 1 | | 3 | 0 | The Third Post | 3rd Lorem ipsum dolor sit ... | laravel | 2020-04-19 19:16:18 | 2020-04-19 19:16:18 | 1 | +----+-----------+-----------------+-----------------------------------+-----------+---------------------+---------------------+---------+ 3 rows in set (0.00 sec)

Perfect! Now we can go next step!

So, see you next time!

Json and Laravel Eloquent with example

JSON is short form of JavaScript Object Notation, which is used to store data and since it is very lightweight hence majorly used for transporting data to and from a web server. In earlier days, XML was used for this very purpose but writing and reading XML data was very tedious while JSON on the other hand, is self describing.

In today’s topic I am going to show you how to store JSON data into MySQL and access those data using laravel eloquent query builders.

Storing JSON data in MySQL using Laravel

First let’s create a dummy table using migration command.

Schema::create(json_examples, function (Blueprint $table) { $table->bigIncrements('id'); $table->string('name'); $table->text('json_details'); //using text datatype to store json $table->timestamps(); });

As you can see I used text datatype for storing json.

Next, let’s create a corresponding Model for the same

php artisan make:model JsonExample

JsonExample.php

public static function create($data) { $new = new self(); $new->name = $data['name']; $new->json_details = $data['json_details'']; $new->save(); }

So in controller we can do something like this:

public function storeEmpData(Request $request) { ... $name = $request->name'; $details = ['emp_code' => '001', 'date_of_joining' => Carbon::parse($request->doj), 'salary' => '50000']; $dataToStore = [ 'name' => $name, 'Json_details' => json_encode($details) ]; //saving data JsonExample::create($dataToStore); }

Processing Json data in Laravel eloquent.

Json data in where()

We can easily apply conditions on json data in laravel using -> (arrow notation), for example, fetch records where salary is more than 50000.

JsonExample.php

public static function getSalaryMoreThan($salary) { return self::where('json_details->salary','>',$salary)->get(); }

Access json data using json_extract()

Another example, we need records of employees who joined the company before a date for instance 9th November 2018.

JsonExample.php

public static function getEmployeesBeforeDate($date) { return self::whereDate("json_extract('json_details', '$.doj')", '<', $date)->get() }

As you can see above, I used json_extract() method which is MySQL’s function to extract a field from JSON column since I can not simply instruct eloquent using arrow operator like

return self::whereDate('json_details->doj', '<', $date)->get()

Rather I have to explicitly tell eloquent to extract json field and then proceed.

JSON data in DB::raw()

Many times we need to use MySQL’s aggregate functions like SUM() as per the requirement, in that case we use DB facade. For example,

select(DB::raw('sum(...)'))

How to access json field in MySQL’s aggregate function ?

It is very simple, let’s take an example, we need to sum total salary of employees.

public static function findTotalSalary() { return self::select(DB:raw('sum("json_extract('json_details', '$.salary')") as total_salary'))->get(); }

Conclusion

That’s all about this topic friends, I hope you learned something new which you haven’t thought about. I thought I should share this knowledge as I encountered such problem while working on a project today where I do save additional data in json format. Do comment your reviews and experiences below.

Thank you :)

Best Tools for Laravel Development

PHPSTORM:

The best IDE for the Laravel framework is PHPStorm. PHPStorm is easy to use, with intelligent code navigation, quick and safe refactoring, simple debugging, and unit testing. It's also useful as a PHP code formatter.

While debugging codes saves time, learning how to code is essential for becoming a successful developer. Because of its high performance, many developers prefer PHPStorm.

Bitbucket:

The most popular Git services are GitHub and BitBucket. They both perform the same functions, but there are some distinctions. Use BitBucket if you're working on a Laravel-based project for a small business.

BitBucket is a good choice for people with a small number of collaborators who require private repositories. The various plans all provide unlimited access to private repositories, but the free plan only allows for five collaborators. GitHub, on the other hand, is a better choice for people working on open source projects because it allows for an unlimited number of collaborators.

It is simple to pull and push the source code, and it automatically combines the code with modifications and timestamps.

Laravel Debug bar:

When it comes to application debugging, Laravel shines. The debug bar in Laravel is to blame for all of this. It displays information about the debug mode when you click it at the bottom of the browser. You can see how many queries have been fired in the debugger's queries tab.

The template's output and parameters are shown. The developer can also see that the Façade option for adding messages will be available under the 'Message' tab of this debugger.

Laravel Forge:

Laravel Forge is a PHP server automation Laravel tool for preparing your web application for deployment. Among its notable features are security by default, database backups that install SSL certificates in seconds, easily set up required SSH keys, free SSL certificates, and so on.

Laravel 9 GEO Chart Example using LavaCharts

We will teach you about Laravel - GEO Chart Example using lavacharts in this article. Here, we'll explain in detail how to use Laravel's GEO Chart Example utilizing lavacharts and provide you with a sample if that's what you need. Today, I'm going to demonstrate how to use the lavacharts package to add a geochart to your Laravel 5 application. Typically, we used geochart on the back end to visually check users according to their country. In this article, we'll use a geo-chart that shows the number of users by country. The benefit of lavachart is that you can manage all data with chart metadata from the controller, rendering just on view. Other charts, such as bar charts, area charts, column charts, pie charts, and line charts, are also available at lavacharts. We'll utilize a geo chart with excellent graphics in this post. You just need to follow a few steps and you can use it in your Laravel application to receive the output seen in the preview below.

Step 1: Installation

Downloading the Lavacharts package in order to create a chart file from a view blade file is the first step. Run the following command in your terminal first, then: composer require khill/lavacharts Open the config/app.php file right now and add the service provider. 'providers' =>

Step 2: Add Table and Model

We need to make a new table called "country users" so that we can get data from it; you can make your own table instead, but this is just an example. Using the Laravel 5 php artisan command, we need to build a migration for the country users table. To start, run the following line: php artisan make:migration create_country_users_table Following this command, you will find a file in the database/migrations directory. You must add the following code to your migration file in order to build the country users table. use IlluminateDatabaseSchemaBlueprint; use IlluminateDatabaseMigrationsMigration; class CreateCountryUsersTable extends Migration { public function up() { Schema::create('country_users', function (Blueprint $table) { $table->increments('id'); $table->string('name'); $table->integer('total_users'); $table->timestamps(); }); } public function down() { Schema::drop("country_users"); } } Create the CountryUser model for country users after creating the "country users" table by creating the following file in the app/CountryUser.php directory: app/CountryUser.php namespace App; use IlluminateDatabaseEloquentModel; class CountryUser extends Model Okay, you may now add a few records as seen below: See also: How to use Highcharts to add charts in Laravel.{ public $fillable = ; } Okay, you may now add a few records as seen below: See also: How to use Highcharts to add charts in Laravel.

Step 3: Add Route

We must include the route in this stage in order to generate the view. so add the following route by opening your app/Http/routes.php file. Route::get('laracharts', 'ChartController@getLaraChart');

Step 4: Create Controller

In this directory, app/Http/Controllers/ChartController.php, we should now construct a new controller named ChartController. Ensure that the country users table contains some data. The following information should be included in the controller file because it will manage data, chart data, and view files: app/Http/Controllers/ChartController.php namespace AppHttpControllers; use IlluminateHttpRequest; use KhillLavachartsLavacharts; use AppCountryUser; class ChartController extends Controller { public function getLaraChart() { $lava = new Lavacharts; // See note below for Laravel $popularity = $lava->DataTable(); $data = CountryUser::select("name as 0","total_users as 1")->get()->toArray(); $popularity->addStringColumn('Country') ->addNumberColumn('Popularity') ->addRows($data); $lava->GeoChart('Popularity', $popularity); return view('laracharts',compact('lava')); } }

Step 4: Create View File

The final step is to build the view file "laracharts.blade.php" in order to generate the view chart. To do this, create the file and add the following code: resources/view/laracharts.blade.php You may now go and check. Here is a link where you may learn more about laracharts: laracharts. I'm hoping this code and text will help you use Laravel 9 GEO Chart Example using LavaCharts Example. Read the full article
