#Python's Django

[heart-ghost-studyblr]

This one has an interesting story. It was in a place where we shared files through a shared data server locally (localhost only), so there was no network access to use the famous "I love PDF" or software like Adobe to convert and make some changes.

With that in mind, I used the PyPDF library to make a code that changes like converting, splitting, merging, and set it up on the server for people to use. Everyone loved both how the program worked and the crazy aesthetic that I made it and my boss approved. Well, problem solved! And fun too, I must say. And since this is a Studyblr, I have to mention how worthwhile it is to study a library you've never seen before but that seems to do everything you need at that moment. Putting a small project into practice, seeing how people react to it, then studying and improving it in a way that reflects your own growth. That was made with Django Web Framework.

VS Codeで仮想環境が効かない！？Django開発環境構築でハマったエラーの全記録

この記事は、Windows環境でPythonとDjangoを使って開発を始めた際、Visual Studio Code（VS Code）上で仮想環境の設定に関して発生した複数のトラブルについて記録したものです。仮想環境を有効にしたはずなのにPythonが見つからない、Djangoサーバが起動しない、ライブラリが入っていない、など……。その一つ一つが地味に時間を削るものばかりで、この記事が誰かの参考になればと思って残しておきます。

PowerShellで仮想環境に入れない

最初のつまずきは「仮想環境のアクティベート」でした。私は PowerShell を使って以下のコマンドを実行しました。

venv\Scripts\activate

すると、以下のようなメッセージが返ってきました：

モジュール 'venv' を読み込むことができませんでした。

これは PowerShell では activate ではなく、Activate.ps1 を使う必要があるためです。

.\venv\Scripts\Activate.ps1

この修正で無事仮想環境に入ることができましたが、これはまだ始まりに過ぎませんでした。

仮想環境に入ったのにPythonが使えない

仮想環境に入った状態で Django の開発サーバーを起動しようとしました：

python manage.py runserver

しかし、なんと返ってきたエラーはこれ：

No Python at '"/usr/bin\python.exe'

WindowsでなぜUnix風のパス？しかも usr/bin の後に python.exe が混ざっているという奇妙な状態でした。

実はこれ、仮想環境が正しくアクティベートされているように見えて、VS Code が別の仮想環境（C:\Python\.venv）を参照していたことが原因でした。プロジェクト直下の .venv を使いたいのに、VS Code の設定が上位のグローバル仮想環境を見に行っていたのです。

where python が効かない

仮想環境内で where python を実行しても何も返ってきませんでした。そこで外部の cmd.exe を使って同じコマンドを打つと、次のように表示されました：

C:\Python\WonderPasNavi\.venv\Scripts\python.exe C:\Users\user\AppData\Local\Programs\Python\Python39-32\python.exe

この結果から、PowerShell 内での仮想環境のパスが正常に反映されていないことが分かりました。どうやら VS Code の PowerShell ターミナルでは環境変数 PATH の更新がうまく行われていなかったようです。

見えない .vscode と仮想環境指定

VS Code の仮想環境設定は通常、プロジェクト直下の .vscode/settings.json に保存されます。しかしこのフォルダが作成されていなければ、VS Code がどの Python を使うべきか迷ってしまいます。今回は .vscode フォルダが存在しておらず、設定ファイルもない状態でした。結果、Python拡張機能が以前の仮想環境を優先してしまっていたわけです。

Djangoサーバは起動したが…

仮想環境を再度正しくアクティベートして、python manage.py runserver を実行。すると、今度は次のエラーが表示されました：

ModuleNotFoundError: No module named 'django_bootstrap5'

そうです、ライブラリが入ってなかったんです。プロジェクトの settings.py に 'django_bootstrap5' が記述されているにも関わらず、依存パッケージが仮想環境にインストールされていませんでした。

対処法は単純です。

pip install django-bootstrap5

これでエラーは解消され、ついにサーバが起動しました。ここまでくるのに何時間かかったことか……。

まとめ：「この苦労を…」

VS Code + Python + Django の仮想環境構築は、一見簡単そうに見えて、罠が多いです。

仮想環境の activate の方法は PowerShell / CMD で異なる

VS Code の Python拡張は過去の設定を引きずることがある

ターミナルごとに仮想環境の有効化状態が違う可能性がある

仮想環境の python.exe が本当に使われているか確認するには where python が超重要

この苦労を、未来の自分や他の誰かが繰り返さないように、この記事を残します。

「仮想環境、ちゃんと動いてる？」って思ったら、まずは where python で確認しよう。

Coding in Python feels like creating something out of thin air. It’s simple, yet powerful—turning messy ideas into something real with just a few lines. There’s a kind of joy in seeing a script run smoothly, like solving a puzzle and watching all the pieces fit.

Some days, it’s frustrating. The bugs, the errors, the moments when nothing makes sense. But then, there’s that moment when it clicks, and suddenly, you feel unstoppable. Like you can build anything, automate anything, bring any idea to life.

That’s what I love about coding. It makes the impossible feel possible.

project updates 🐸

i keep forgetting to post here. i recently had a lot of progress in a project ^^ this is a PWA and we're using python django (and it's required that we should integrate an AI feature too TT) i think i'm 75% done with the front-end but overall we're probably only 15%,,, i'm gonna try finishing my part this week so i could help with other tasks!

there's only three weeks left before the deadline </3 hope it all wrks out

LiftMore Update 9.04.2023

I was posting updates on my Medium (see the pinned post), but lately I haven't had time to make a thorough post. Instead, I want to update on a few things in a more informal post here.

API Updates

Finally went through and added all of the endpoints I'll need. There are a few endpoints on this list that I'm still in the process of refining permissions and making more secure.

Unit Testing ...ayup.. I came this far into the project without writing a single unit test. I really do want to strive for best TDD practices, but when there's no code at all in my application, it feels really unsatisfying to start working on tests before my code is capable of doing anything. Moving forward in the project, I will definitely strive to do TDD well.

Security Currently, the API just processes users via Basic Authentication. In this upcoming week, I'm planning on creating an identity server and using that server to issue my own OAuth2.0 tokens. I'm not sure yet how I want to set up my IDP service and OIDC Identity Providers.

Deployments Before moving onto the Front-End for this project, I want to make sure that my app is as secure and robust as possible. For this, I want to create 3 different environments (Development, Test, and Production), use a secret manager to inject secrets into the application, and have all of my deployments automated with GitHub Actions. In addition to all this, I want to make sure my application is set up properly between GitHub Actions and AWS so that I can manage dashboards and collect usage/cost information before having any users.

Finally, I'm happy to say that I've acquired the domain name "liftmore.app". After I get through some of the things I mentioned here, I'll push out a landing page and more information of LiftMore from a user perspective in case anybody wants to use it :)

Lastly, little brief preview of my Project board in GitHub at the moment.

[jukain4216]

If anyone here has experience with django testing can I get some help please I quite literally have never written tests for my code (yes I like to live dangerously)

[pythondjangoflask]

remove specific element in python list - remove index based element

[raaraaraariya]

Does posting this make me look smart?😏

Yes

The answer's yes

[pixiedust111]

It's been a real fun! I'm hoping to work on the front end next and make it available for everyone 😁!

Я парочку дней решил пообщаться с джином, и мы с ним вещей наделали.

Что я еще собираюсь сделать? Ну есстественно это постоянно улучшать по возможности как функционал, так и интерфейс.

Хочу добавить статистики интерактивной, с парсерами, с постоянным мониторингом, во время работы процесса сервера... Что бы статистику делать реалтайм... На главной странице сделать один блок, который будет как бы постоянным, т.е. закреплённым. А котором будет так же какая нибудь интерактивная информация. Поиск верну)...
