tastypie obj_create and authorization

Question

I use tastypie 0.12.2-dev to create API for my django site. I wrote a class authorization (ApprovedLaptopsAuthorization) and used it in my ModelResource (RecordResource) class. The endpoint of RecordResource is http://myserver/book/api/record.

HTTP GET Request to that endpoint is working correctly. (permissions are checked in read_list() method of ApprovedLaptopsAuthorization class). Now I try to check HTTP POST Request by sending correct JSON data. The problem is that any of ApprovedLaptopsAuthorization methods (create_list(), create_detail()) does not running during that operation. As a result, I can not restrict access to create object operation and any user can create object in any time. Where the mistake in my code?

class ApprovedLaptopsAuthorization(Authorization):
    """
    Авторизация путем проверки наличия разрешения на использоание планшета, с которого осуществляется запрос
    """

    def __init__(self):
        pass

    def read_list(self, object_list, bundle):
        if not bundle.request.user.laptop.approved:
            raise Unauthorized(u"Доступ планшета к данным не подтвержден администратором.")
        return object_list

    def read_detail(self, object_list, bundle):
        if not bundle.request.user.laptop.approved:
            raise Unauthorized(u"Доступ планшета к данным не подтвержден администратором.")
        return True

    def create_list(self, object_list, bundle):
        print "create list"
        if not bundle.request.user.laptop.approved:

Answer 1

I have not received an answer to my question, and added these lines to the top of the method RecordResource.obj_create():

if not bundle.request.user.laptop.approved:
    raise Unauthorized(u"Доступ планшета к данным не подтвержден администратором.")
