Question

所以我觉得布局非常简单。我的配置路由是：

  resources :webcomics
  match '/webcomics/first' => 'webcomics#first', :as => :first
  match '/webcomics/random' => 'webcomics#random', :as => :random
  match '/webcomics/latest' => 'webcomics#latest', :as => :latest

控制器：

  def show
    @webcomic = Webcomic.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @webcomic }
    end
  end

  def first
    @webcomic = Webcomic.order("created_at ASC").first
    respond_to do |format|
      format.html { render 'show'}
      format.json { render json: @webcomic }
    end
  end

导航栏：

<%= link_to first_webcomics_path, :rel => "tooltip", :title => "first comic" do %>
              formatting in here
        <% end %>

当我点击此链接时，它会将我发送到正确的路径/ webcomics /首先，但它给了我错误

Routing Error
No route matches {:action=>"edit", :controller=>"webcomics"}

我想知道怎么去'编辑'，不管这条消息是完全错的，我都有编辑，但为什么要尝试去编辑动作。

def edit
    @webcomic = Webcomic.find(params[:id])
end

佣金路线的结果：

 first_webcomics GET    /webcomics/first(.:format)    webcomics#first
latest_webcomics GET    /webcomics/latest(.:format)   webcomics#latest
random_webcomics GET    /webcomics/random(.:format)   webcomics#random
       webcomics GET    /webcomics(.:format)          webcomics#index
                 POST   /webcomics(.:format)          webcomics#create
    new_webcomic GET    /webcomics/new(.:format)      webcomics#new
   edit_webcomic GET    /webcomics/:id/edit(.:format) webcomics#edit
        webcomic GET    /webcomics/:id(.:format)      webcomics#show
                 PUT    /webcomics/:id(.:format)      webcomics#update
                 DELETE /webcomics/:id(.:format)      webcomics#destroy
            root        /                             webcomics#index

Answer 1

将这三个match规则放在resources行之上：

match '/webcomics/first' => 'webcomics#first', :as => :first
match '/webcomics/random' => 'webcomics#random', :as => :random
match '/webcomics/latest' => 'webcomics#latest', :as => :latest
resources :webcomics

原因在Ruby Guides: Routing中解释：

Rails路由按照指定的顺序进行匹配，所以如果你有一个资源：上面的照片得到'照片/民意调查'的节目动作资源行的路由将在获取行之前匹配。至解决这个问题，将get行移到资源行上方，这样就可以了首先匹配。

Answer 2

路由是有序的;将match es放在resources上方。

那就是说，我会考虑adding those routes as RESTful actions：

resources :webcomics
  collection do
    get 'first'
    get 'random'
    get 'latest'
  end
end

IMO这个更清洁一点，而且恰好很合适。

问题在于show模板中的修改链接。编辑链接需要一个对象编辑：

<%= link_to "edit", edit_webcomic_path(@webcomic) %>

Rails路径给我没有路由匹配，但我不明白为什么
