What is the lifecycle of a Django application?
The life cycle of a Django application includes the following steps:
- Configuration: When a Django application starts up, it reads configuration information from the settings.py file, such as database connections, static file paths, etc.
- URL mapping: Django will route requests to the corresponding view functions based on the URL patterns defined in the urls.py file.
- View processing: When a request is routed to a view function, the view function will handle the request and return an HttpResponse object.
- Model Operations: In view functions, database operations such as reading and writing can be performed using Django’s ORM.
- Template rendering: The view function has the option to pass data to the template for rendering, ultimately returning an HttpResponse object containing the rendered content.
- The response returned: Ultimately, Django will return the HttpResponse object to the client, completing the request-response cycle.
- Cleanup: Once the request processing is completed, Django will clean up certain resources, such as database connections, cache, etc.
These steps make up the lifecycle of a Django application, ensuring the smooth running and efficient processing of requests.
