我无法访问在我运行路由时似乎没有嵌套但嵌套在 routes.rb 中的路由

                        PUT    /projects/:id(.:format)                   projects#update
                        DELETE /projects/:id(.:format)                   projects#destroy
                  react POST   /react(.:format)                          reacts#create
              new_react GET    /react/new(.:format)                      reacts#new
              edit_react GET    /react/edit(.:format)                     reacts#edit
                        GET    /react(.:format)                          reacts#show
                        PATCH  /react(.:format)                          reacts#update
                        PUT    /react(.:format)                          reacts#update
                        DELETE /react(.:format)                          reacts#destroy

这里是 Routes.rb

Rails.application.routes.draw do
  resources :projects do
    resources :lists, shallow: true do
      member do
        post :sort
      end
      resources :items, shallow: true
    end
  end
  resource :react
end

还有我的link_to

  <%= link_to %(<span class="glyphicon glyphicon-trash"></span>).html_safe, controller: :lists, action: :create ,remote: true, method: :post %>

我得到了错误

No route matches {:action=>"create", :controller=>"lists", :method=>:post}

我很困惑，因为当我 rake 路由时，它返回列表有一个创建操作。我显然无法正常访问它。感谢您的帮助。

【问题讨论】：

重新启动服务器后尝试 rake 路由是否显示相同的路由？我认为他们不应该是 2 lists#create。
是的，没错。我重新启动了服务器，现在只有一个 list#create POST /projects/:project_id/lists(.:format) lists#create

【解决方案1】：

试试这个：-

根据您的路线，您需要传递 project_id 以作为参数创建操作

<%= link_to project_lists_path(project_id: project.id), method: :post, remote: true do%>
  <span class="glyphicon glyphicon-trash"></span>
<%end%>

或者你也可以试试这个：-

<%= link_to project_lists_path(project), method: :post, remote: true do%>
  <span class="glyphicon glyphicon-trash"></span>
<%end%>
