Мой идентификатор пользователя не сохраняется

Question

Мой идентификатор пользователя не сохраняется, и я не понимаю, почему. Я добавил ассоциации к обоим моделям и добавил user_id к параметрам уведомления, но идентификатор пользователя не сохраняется автоматически.

Отношение campus_id работает нормально, и я не вижу разницы. В чем может быть проблема? Я использую postgress database.

Answer 1

Поскольку user_id не является частью ваших параметров

Из журнала:

Parameters: {"utf8"=>"_", "authenticity_token"=>"L9RH3hZyAKqzq9/kuJJDNaEHNVca2DbQSKSZLc8iTuw=", "notification"=>{"post"=>"thisisatest"}, "commit"=>"Maak notificatie", "campu_id"=>"1"} 

тогда линия от сильного Params фильтрует нежелательный контент

params.require(:notification).permit(:post, :campus_id, :user_id) 

это только "notification"=>{"post"=>"thisisatest"} часть будет разрешено

затем из SQL вставки:

SQL (134.0ms) INSERT INTO "notifications" ("campus_id", "created_at", "post", "updated_at") VALUES ($1, $2, $3, $4) RETURNING "id" [["campus_id", 1], ["created_at", Sat, 18 Oct 2014 19:41:03 UTC +00:00], ["post", "thisisatest"], ["updated_at", Sat, 18 Oct 2014 19:41:03 UTC +00:00]] 

вы campus_id здесь потому, что вы делаете обновление на @campus:

@campus.notifications.build(notification_params) 

так, просто убедитесь, что user_id приходит как часть уведомления, и это все!
