Backend Code requirements

Style

• Obey django's style guide.
• Configure your IDE to use flake8 for checking your python code. For running flake8 manualy, do cd src && flake8
• Prefer English over your native language in comments and commit messages.
• Commit messages should contain the unique id of issue they are linked to (refs #100500)
• Every model and a model method should have a docstring.

Code organisation

• KISS and DRY.
• Obey django best practices
• If you want to implement some business logic — make a service for that. Service examples: UserCreator, OrderCreator
• No logic is allowed within the views or templates. Only services and models.
• Use PEP-484 type hints when possible.
• Prefer Manager methods over static methods.
• Do not use signals for business logic. Signals are good only for notification purposes.
• No l10n is allowed in python code, use django translation.
