Have you had experience working with access control and permissions system in Django?

Yes, Django has a built-in access control and permissions system based on the User and Group models, as well as the permissions mechanism.

Main features:

• Users (User) can have specific permissions, which are set at the model level or for custom actions.
• Groups (Group) allow combining users and assigning permissions to the group, simplifying management.
• Custom permissions can be created and checked in code using methods like user.has_perm('app_label.permission_codename').
• Access to views is often restricted using decorators like @login_required and @permission_required.

Example of permission check in a view:

from django.contrib.auth.decorators import permission_required

@permission_required('app.view_model', raise_exception=True)
def my_view(request):
    # view code
    pass

Thus, the system allows flexible management of access to application resources.
