Rails 4错误：NoMethodError-未定义的方法“ itemfavorites”

Question

Hey I am receiving an issue when accessing @interestedusers = User.itemfavorites.where(item_id: @item.id) from my ItemsController :

NoMethodError in ItemsController#show
undefined method `itemfavorites' for #<Class:0xfb94bb8>

Routes

resources :items do
    get :itemfavorites, on: :member
end

User Model

# Favorite items of user
has_many :favorite_items # just the 'relationships'
has_many :itemfavorites, through: :favorite_item, source: :item # the actual items the user favorites

Item Model

# Favorited by users
has_many :favorite_items # just the 'relationships'
has_many :itemsfavorited_by, through: :favorite_items, source: :user # the actual users favoriting an item

The general association works, I tested it and I can add/remove and display favorites.

I am trying to display the users favorited an Item.

Thanks in advance for each answer! Please tell me if you need additional information.

Answer 1

You are calling itemfavorites on the User class, not a User instance. I guess you want to do something like

@interestedusers = current_user.itemfavorites.where(item_id: @item.id)

or

@interestedusers = @user.itemfavorites.where(item_id: @item.id)

EDIT: you want to do this to get users for an item:

@interestedusers = @item.itemsfavorited_by
