NSLocalizedDescription = Ожидаемый код состояния в (200-299), получил 422}

Question

Я пытаюсь сделать рекламный пост. Я настраиваю все, поскольку я думал, что это будет правильно, однако, когда я нажимаю бозон «cadastrar anuncio», он возвращает эту ошибку «получил 422». уже изученный об ошибке, однако, не мог исправить вообще. кто-то здесь прошел через это?

Вот деталь из журнала сервера

работы POST "/ads.json" для 127.0.0.1 в 2015-03-03 18:06:15 -0300 Обработка AdsController # create as JSON Параметры: {"ad" => {"description" => ewewe "," id "=>" "," local "=>" ew ", " price "=>" 25 "," title "=>" titulp "}} Пользовательская загрузка (0,6 мс) пользователей SELECT. * ОТ пользователей WHERE users.id = 2 ORDER BY users.id ASC LIMIT 1 Непропущенные параметры: id (0.2ms) BEGIN (0.6ms) ROLLBACK Завершено 422 Непроизведенный Entity in 10ms (Просмотров: 0.3ms | ActiveRecord: 1,4ms)

Answer 1

Код состояния 422 указывает, что ваши данные были некорректными - запрос был сформирован, но данные не могли быть обработаны.

Глядя на журнал с сервера вы можете увидеть, что id пуст, и появляется сообщение об ошибке Unpermitted parameters: id

Вам нужно определить, почему идентификатор пуст, и исправить это, прежде чем отправить запрос.
