Question

我正在尝试在我的应用程序中添加书签功能。我已经在routes.rb文件中创建了路线，并且在我的显示页面上实现了一个链接，以使用户能够保存发型。当我单击它时，出现以下错误。 ActionController::UrlGenerationError in Hairstyles#show和

No route matches {:action=>"update", :controller=>"saved_hairstyles", :id=>"21"}, missing required keys: [:hairstyle_id]

到目前为止，我正在关注this video。

为便于理解，这里是my repo。

saved_hairstyles_controller.rb（仅针对更新方法定义）：

class SavedHairstylesController < ApplicationController
  def update 
  saved_hairstyle = SavedHairstyle.where(hairstyle: 
  Hairstyle.find(params[:hairstyle]), user: current_user)
  if saved_hairstyle == []
    SavedHairstyle.create(hairstyle: Hairstlye.find(params[:hairstyle]), user: 
    current_user)
    @saved_hairstyle._exists = true
  else
    saved_hairstyle.destroy_all
    @saved_hairstyle_exists = false
  end
  respond_to do |format|
    format.html {}
    format.js {}
  end
  end
end

我在views>hairstyles>show.html.erb文件中的链接，这是给我错误的链接，

 <%= link_to 'save hairstyle', hairstyle_saved_hairstyle_path(hairstyle: @hairstyle) %>

routes.rb如下，

Rails.application.routes.draw do
  root to: 'pages#home'
  devise_for :users
  resources :hairstyles do
    member do
      put "like", to: "hairstyles#upvote"
      put "dislike", to: "hairstyles#downvote"
    end
    resources :comments, only: :create
    resources :saved_hairstyles, only: [:update]
  end
  resources :saved_hairstyles, only: :destroy
  resources :comments, only: :destroy
  resources :hairdressers
end

问题的补充：我还检查了“耙路| grep saved_hairstyles`，我有以下路线：

hairstyle_saved_hairstyle PATCH  /hairstyles/:hairstyle_id/saved_hairstyles/:id(.:format)                                 saved_hairstyles#update
                          PUT    /hairstyles/:hairstyle_id/saved_hairstyles/:id(.:format)                                 saved_hairstyles#update
          saved_hairstyle DELETE /saved_hairstyles/:id(.:format)                                                          saved_hairstyles#destroy```

我的link_to说没有路径，但是我在routes.rb中创建了路径-没有路由匹配
