路线/控制器问题与“不受欢迎的行动”

Question

我已经使用has_many：through关联实现了一个添加到收藏夹功能。用户现在可以在房间show.html.erb视图中收藏或不喜欢房间。在不同的控制器和视图上，我想显示登录用户的所有喜欢的房间。

我希望用户能够删除每个喜欢的房间。展示所有房间是没有问题的，不幸的是我不能用不受欢迎的按钮来完成这项工作。

我该如何使用？

rooms_controller.rb

before_action :set_room, only: [:show, :favorite]
...
  def favorite
    type = params[:type]
    if type == "favorite"
      current_user.favorites << @room
      redirect_to wishlist_path, notice: 'You favorited #{@room.listing_name}'

    elsif type == "unfavorite"
      current_user.favorites.delete(@room)
      redirect_to wishlist_path, notice: 'Unfavorited #{@room.listing_name}'

    else
      # Type missing, nothing happens
      redirect_to wishlist_path, notice: 'Nothing happened.'
    end
  end

  private
    def set_room
      @room = Room.find(params[:id])
    end

static_pages_controller.rb

  def wishlist
  end

wishlist.html.erb

<div>
<% current_user.favorites.each do |room| %>
    <%= room.listing_name %>
    <%= link_to "unfavorite", favorite_room_path(@room, type: "unfavorite"), method: :put %>
<% end %>
</div>

的routes.rb

Rails.application.routes.draw做

  root 'static_pages#welcome'
  get 'wishlist' => 'static_pages#wishlist'

  resources :rooms, only: [:index, :show] do 
    resources :reservations, only: [:create]
    resources :reviews, only: [:create, :destroy]
  end

  resources :rooms do
    put :favorite, on: :member
  end

Answer 1

在whishlist.html.erb中，您正在使用＆＃39; @ room＆＃39;而不是＆＃39; room＆＃39;。 @room仅在房间控制器中设置，而不是静态页面控制器。
