使用 link_to 或 button_to rails 访问嵌套路由时遇到问题

Question

我无法访问一条路线，当我运行路线时，该路线似乎没有嵌套，但嵌套在 routes.rb

中

                        PUT    /items/:id(.:format)                      items#update
                        DELETE /items/:id(.:format)                      items#destroy
          project_lists GET    /projects/:project_id/lists(.:format)     lists#index
                        POST   /projects/:project_id/lists(.:format)     lists#create

              edit_list GET    /lists/:id/edit(.:format)                 lists#edit
                        GET    /lists/:id(.:format)                      lists#show
                        PATCH  /lists/:id(.:format)                      lists#update
                        PUT    /lists/:id(.:format)                      lists#update
                        DELETE /lists/:id(.:format)                      lists#destroy
                projects GET    /projects(.:format)                       projects#index
                        POST   /projects(.:format)                       projects#create
            new_project GET    /projects/new(.:format)                   projects#new
            edit_project GET    /projects/:id/edit(.:format)              projects#edit
                project GET    /projects/:id(.:format)                   projects#show
                        PATCH  /projects/:id(.:format)                   projects#update
                        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 %>

我收到错误

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

我很困惑，因为当我对它进行 rake 路由时 returns 有一个列表的创建操作。我显然无法正常访问它。感谢您的帮助。

试试这个：-

根据您的路线，您需要传递 project_id 以将创建操作作为参数

<%= 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%>
