How do I create custom context managers in Django?

To create a custom context manager in Django, you can use the contextlib module or define a class with __enter__ and __exit__ methods.

Can you give me an example of a custom context manager?

Sure! Here's a simple example:

class MyContextManager:
    def __enter__(self):
        # Setup code here
        return self

    def __exit__(self, exc_type, exc_value, traceback):
        # Cleanup code here

with MyContextManager() as manager:
    # Your code here

What are some use cases for context managers in Django?

Context managers are useful for managing resources like database connections, file operations, or transactions, ensuring proper setup and teardown.

Is there a way to use context managers with database transactions?

Yes, you can use Django's built-in transaction management with context managers to ensure that your database operations are atomic.
