Хей,
това е разочароващо. Знам какво не е наред тук, но нямам решение да го поправя.
Първо грешката, подкана при щракване върху „Любими“ (/app/views/users/index.html.haml)
ActiveRecord::HasManyThroughSourceAssociationNotFoundError in UsersController#userfavorite
Could not find the source association(s) "userfavorite" or :userfavorites in model FavoriteUser. Try 'has_many :userfavorites, :through => :favorite_users, :source => <name>'. Is it one of c_user_id or user_id?
Заявка: Параметри:
{"_method"=>"get",

"type"=>"favorite", # What i am doing
"id"=>"1"} # My user id
Моята цел е да позволя на потребителите (от потребителския модел) да предпочитат други потребители (потребителски модел) чрез любимия потребителски модел. Конфликтът тук: не мога да направя асоциациите правилно, защото имам само един модел, от който идват данните.
Нека ви покажа кода много бързо! (Конфликти user.rb)

(=> c_user_id за текущия потребителски идентификатор - така че потребителят, който добавя любими потребители)
Надявам се, че предоставените данни са достатъчни, ако не, моля, кажете ми. Благодарен съм за всички ваши отговори.
