How can the auth module in Django be utilized?

The auth module in Django provides features for user authentication and authorization. Here are some common operations using Django’s auth module.

1. Create user:
2. Import the User model from django.contrib.auth.models.

   Create a new user with the username ‘john’ and password ‘password123’.

3. User Sign In:
4. Import authenticate and login from the django.contrib.auth module.
   Check if the user is successfully authenticated using the username ‘john’ and password ‘password123’.
   If the user credentials are valid, then log in the user.
5. The request here refers to the request object in the view function.
6. User logged out.
7. Use the logout function from the Django auth module and pass in the request as an argument.
8. Check if the user is already logged in.
9. if the user is authenticated:
   # user is logged in
   else:
   # user is not logged in
10. User authorization:
11. After importing the necessary decorator from the Django authentication module, we proceed with the subsequent operation only if the user is logged in.
12. Using the @login_required decorator can restrict access to the view function to only logged-in users.
13. Check user permissions:
14. if the user has permission to edit in ‘myapp’,
    # the user has edit permission
    else:
    # the user does not have edit permission
15. The ‘myapp.can_edit’ here is a permission identifier that can be defined in Django’s permission management.

This is just some common usage of the auth module in Django, for more detailed usage methods, refer to the official Django documentation.
