Question

No route matches {:controller=>"guides", :action=>"favorite", :id=>nil, :format=>nil, :type=>"favorite"} missing required keys: [:id]

我正在尝试在我的应用程序中获取收藏列表。用户应该能够收藏和不受欢迎的指南。

指南控制器中最喜欢的操作：

def favorite
    @guide = Guide.find(params[:id])
      type = params[:type]
      if type == "favorite"
        current_user.favorites << @guide
        redirect_to :back, notice: 'You favorited #{@guide.title}'

      elsif type == "unfavorite"
        current_user.favorites.delete(@guide)
        redirect_to :back, notice: 'Unfavorited #{@guide.title}'

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

favorite_guide.rb

class FavoriteGuide < ActiveRecord::Base
  belongs_to :guide
  belongs_to :user 
end

guide.rb

  has_many :favorited_by, through: :favorite_guides, source: :user

的routes.rb

  resources :guides do
    member do
      put "like", to: "guides#upvote"
      put "dislike", to: "guides#downvote"
    end
    put :favorite, on: :member
  end

以下是我在视图中打印出来的方式：

<%= link_to "favorite",   favorite_guide_path(@guide, type: "favorite"), method: :put %>
  <%= link_to "unfavorite", favorite_guide_path(@guide, type: "unfavorite"), method: :put %>

修复

<%= link_to "favorite",   favorite_guide_path(@guide, type: "favorite"), method: :put %>
<%= link_to "unfavorite", favorite_guide_path(@guide, type: "unfavorite"), method: :put %>

到

<%= link_to "favorite",   favorite_guide_path(guide, type: "favorite"), method: :put %>
<%= link_to "unfavorite", favorite_guide_path(guide, type: "unfavorite"), method: :put %>
