How To Use Chart JS In Laravel 

The fundamentals of Chart.js are quite straightforward. First, we must install Chart.js into our project. Depending on the settings of your project, you may be installing it using npm or bower, or you may link to a constructed version via a CDN or clone/build from GitHub. Simply connecting to the created CDN version in the sample's blade file would suffice for this brief example. A The fundamentals of Chart js are quite straightforward. First, we must install Chart js into our project. Depending on the settings of your project, you may be installing it using npm or bower, or you may link to a constructed version via a CDN or clone/build from GitHub. In our examples, we'll only link to the built-in CDN version for the purposes of this brief demonstration. We'll just plot the ages of the app users in this case. We're presuming you've already set up the Laravel auth scaffolding and carried out the required migrations to make a Users table. If not, take a look at the information here or modify it for the model you're using for your chart's data. Therefore, before creating any users at random, we'll first add an age column to our Users table. For more information, see our post on how to use faker to create random users, however for this demonstration, let's make a database migration to add an age column by using: add age to users table php artisan make:migration —table='users' To change the up function to: edit this file in the database migrations directory. Schema::table('Users', function (Blueprint $table) { $table->int('age')->nullable(); }); Run php artisan migrate after that, and your Users table should now contain an age column. Visit /database/factories/UserFactory now, and add the following at the end of the array: 'age' is represented by $faker->numberBetween($min = 20, $max = 80), The complete return is thus: return ; Run the following commands to build a UsersTableSeeder: make:seeder UsersTableSeeder in PHP This will produce UsersTableSeeder.php in the database. The run function should include the following: factory(AppUser::class, 5)->create(); When this is executed, 5 users will be created; modify 5 to the number of users you need. After that, we must open DatabaseSeeder.php in /database/seeds and uncomment the code in the run() function. Finally, execute php artisan db:seed. Five new users should appear, each of whom has an age. For our Charts page, we will now develop a model, controller, views, and routes. Run the following command in PHP: make:controller ChartController —model=Chart. To the file /app/Http/Controllers/ChartController.php, add the following: use AppUser; use AppChart; use DB; ... public function index() { // Get users grouped by age $groups = DB::table('users') ->select('age', DB::raw('count(*) as total')) ->groupBy('age') ->pluck('total', 'age')->all(); // Generate random colours for the groups for ($i=0; $ilabels = (array_keys($groups)); $chart->dataset = (array_values($groups)); $chart->colours = $colours; return view('charts.index', compact('chart')); } The random colour scheme is one example of the exciting things you can do with the controller's data, though you can also specify hardcoded colours if you'd choose. In /resources/views/charts/, we must now create an index.blade.php file and add the following (depending on your blade setup and layout; here is an example): Laravel Chart Example Chart Demo Finally, we need to add the following to /routes/web.php: Route::get('/charts', 'ChartController@index')->name('charts'); Go to at your-project-name.test/charts now. Although this should serve as a good starting point for your understanding of the fundamentals of charts and graphs in Laravel, you may refer to the Chart.js documentation for more details on customizing your charts.

What are the Key Features of the Laravel?

As a more sophisticated alternative to the CodeIgniter framework, which lacked features like built-in user authentication and authorisation, Laravel was initially developed. When we refer to Laravel's original release, we mean the beta version, which was made available on June 9, 2011, and Laravel 1, which was made available later that month. Laravel 1 was regarded as the best option for websites or applications because it has built-in support for authentication, localization, models, views, sessions, routing, and many more techniques.

Construction of a database table is made possible by Laravel's crucial migration feature. It enables you to modify and distribute the application's database schema. A new column can be added to the table, or an existing one can be eliminated.

Faker is a PHP (Laravel) testing tool that creates fictitious data. Using Faker, you can produce as much test data as you require. The Laravel framework includes Faker. Faker can also be used on your own PHP-based websites or in other frameworks.

A method for automatically adding dummy data to the database is provided by Laravel. The process is referred to as seeding. Developers may quickly add test data to their database table by using the database seeder. By testing with different data formats, it enables developers to identify problems and maximise efficiency, which is quite helpful.

The important distinction in this case is how this release increased Laravel's popularity. Laravel is available in versions 1, 2, 3, 4, 5, 5.1, 5.3, 5.4, 6, 7, and most recently, Laravel 9.

The following are the most important features of Laravel 4.

Database seeding is used to initially populate databases.

There is built-in support for sending a variety of email formats.

There is support for the message queue.

support for the deletion of database records after a predetermined period of time (Soft deletion).

The following are the most important features of Laravel 5.

You can schedule jobs to be executed on a regular basis using the scheduler programme.

An abstraction layer called Flysystem makes it possible to use remote storage in the same way that local file systems are used.

External authentication can be handled more easily with the help of the optional Socialite package.

Package asset management is better with Elixir.

A new internal directory tree structure has been made for produced programmes.

Additionally, version 5.1 was updated.

The following are the most important features of Laravel 8.

Laravel's Jetstream module is used.

In the model factory, classes.

Migratory suffocation

Use Tailwind CSS for usability improvements such as pagination views.

Do you want to learn how to utilise Laravel? Knowledge and tools required

Intermediate understanding of PHP

Returning to the BusinessTest

With some more advanced tools in place, it is time to revisit my efforts with the BusinessTest class.

The first thing to do is to add a factory for the Business model. Using the User factory as an example, I’m able to create a factory to create businesses for use in tests.

$factory->define(App\Business::class, function (Faker\Generator $faker) {    return [        'name' => $faker->company,        'zip_code' => $faker->postcode,        'active' => true,        'created_at' => Carbon::now(),        'updated_at' => Carbon::now(),    ]; });

This appears in ModelFactory.php. I looked over the schema for the table to confirm that each of the attributes is covered. I also added “use Carbon/Carbon;” at the top.

I then moved BusinessTest.php into the tests/integration/models directory. I added support for DatabaseTransactions as well, like in the UserTest.php file. Then I tried to write a test for the slug. This returned the following error: “InvalidArgumentException: Unable to locate factory with name [default] [App\Business].” Once again, Laravel is returning an obscure error. After chasing various red herrings related to namespaces, I started removing bits of the file until it looked more and more like UserTest.php. Ultimately, it turned out that with TestCase, the setup() function needs to call parent::setup(). It also needs special handling to deal with the database transactions.

I set that aside for now. Perhaps with the factories, the need for a setup() is no longer as important. So I removed the setup and continued.

/** @test */ function a_business_has_a_slug() {    $business = factory(Business::class)->create(['name' => 'Dan\'s 12 Amazing Donkeys & Donuts']);    $this->assertEquals('dans-12-amazing-donkeys-donuts', $business->slug()); }

Without setup() breaking things, this test passed green. The factory doesn’t set a value for slug, so I know that the model is doing the work here, as it should.

Next, I can test that hasEmployee($user) returns false when a company has no employees and $user is null.

function test_a_null_is_not_an_employee_in_a_business_with_no_employees() {    $nullUser = null;    $noEmployeesBusiness = factory(Business::class)->create();    $this->assertFalse($noEmployeesBusiness->hasEmployee($nullUser)); }

Again, setup is disabled here, so I created a business using the factory. This test passes.

To test the scenarios where a business has employees, I will need to create objects for User, Business, and Employee with the correct foreign keys, and that’s where I will turn my focus tomorrow.
