How can I implement custom permissions in Django admin?

You can implement custom permissions in Django admin by overriding the has_change_permission, has_add_permission, and has_delete_permission methods in your ModelAdmin class.

Can you give me an example of how to override these methods?

Sure! Here's a simple example:

class MyModelAdmin(admin.ModelAdmin):
    def has_change_permission(self, request, obj=None):
        return request.user.is_superuser  # Only superusers can change objects

    def has_add_permission(self, request):
        return request.user.has_perm('app.add_mymodel')  # Custom permission check

    def has_delete_permission(self, request, obj=None):
        return False  # No one can delete objects

This restricts permissions based on user roles.

What if I want to add a custom permission for a specific user group?

You can check for group membership in your permission methods. For example:

if request.user.groups.filter(name='MyGroup').exists():
    return True  # Allow access for users in 'MyGroup'
