NoMethodError Rails 5

Question

我想讓用戶可以爲各種咖啡店添加書籤。我已經成功設法讓用戶喜歡咖啡店，所以試圖按照相同的步驟，但我試圖加載Coffeeshops#show時得到一個NoMethodError。

我的代碼：

user.rb

class User < ApplicationRecord 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :validatable, 
    has_many :comments 
    has_many :coffeeshops 
    has_many :favorite_coffeeshops # just the 'relationships' 
    has_many :favorites, through: :favorite_coffeeshops, source: :coffeeshop 
    has_many :bookmarked_coffeeshops # just the 'relationships' 
    has_many :bookmarks, through: :bookmarked_coffeeshops, source: :coffeeshop 

coffeeshop.rb

class Coffeeshop < ApplicationRecord 

    has_many :comments, as: :commentable 
    belongs_to :roaster 
    belongs_to :user 
    has_many :favorite_coffeeshops# just the 'relationships' 
    has_many :favorited_by, through: :favorite_coffeeshops, source: :user 
    has_many :bookmarked_coffeeshops# just the 'relationships' 
    has_many :bookmarked_by, through: :bookmarked_coffeeshops, source: :user 

bookmarked_coffeeshop.rb

class BookmarkedCoffeeshop < ApplicationRecord 
    belongs_to :coffeeshop 
    belongs_to :user 
end 

coffeeshop.show.html.erb

<%= link_to "Bookmark", bookmarked_coffeeshops_path(@coffeeshop, type: "bookmarked"), method: :put %>

遷移

class CreateBookmarkedCoffeeshops < ActiveRecord::Migration[5.0] 
    def change 
    create_table :bookmarked_coffeeshops do |t| 
     t.integer :coffeeshop_id 
     t.integer :user_id 

     t.timestamps 
    end 
    end 
end 

錯誤

undefined method `bookmarked_coffeeshop_path' for #<#<Class:0x007fadb9ccad30>:0x007fadc3232e90>

小學生的錯誤 - 我hadn 「T更新了我的路線：

添加：

resources :coffeeshops do 
    put :bookmarked, on: :member 
end 

解決了這個問題。
