In an admin custom view I had the requirement to modify the upload handlers.
However, the @staff_member_required locked the Files upload handlers as it uses the request.POST - see Ticket 7654.
These decorators can be used before other decorators to allow setting of the upload handlers.
Usage example:
@upload_handlers_insert(0, QuotaUploadHandler)
@staff_member_required
def upload(request):
pass

"""

def _decorator(view_func):

Edited - should pass uninitiated class to the decorator - it will then handle the initiation and will return a fresh instance per request.
