How to set django upload_handler in admin?

Question

I'm trying to make a django upload progress bar within the django admin. The application is only a small part of the project, therefor I do not want to set the custom upload handler in the settings.py.

The upload_handler can be set with request.upload_handlers.insert(0, UploadProgressHandler(request)) but not within the add_view of the django admin class. The response is this exception:

If you try to modify request.upload_handlers after reading from request.POST or request.FILES Django will throw an error.

I also tried doing this with a decorator over the add_view but then I do not know how to access the request.upload_handlers.

Can someone help me out?

Have a look at the source for the decorator that comes with the admin app:

def staff_member_required(view_func):
    """
    Decorator for views that checks that the user is logged in and is a staff
    member, displaying the login page if necessary.
    """
    @wraps(view_func)
    def _checklogin(request, *args, **kwargs):
        if request.user.is_active and request.user.is_staff:
            # The user is valid. Continue to the admin page.
            return view_func(request, *args, **kwargs)

The decorator 'wraps' the original view so you are able to check the request arg before calling the original view func with it.
