Question

这是我的 routes.rb 填充

Rails.application.routes.draw do
  namespace :main, path: ':master_url' do
    root 'sites#index'
    namespace :dashboard do
        root 'dashboards#index'
        #get 'masters/index'
      resources :masters
    end
    get "/:action" => 'sites#:action'
  end
  root 'main/sites#index'

end

这是命令佣金路线

                 main_root GET    /:master_url(.:format)                            main/sites#index
       main_dashboard_root GET    /:master_url/dashboard(.:format)                  main/dashboard/dashboards#index
    main_dashboard_masters GET    /:master_url/dashboard/masters(.:format)          main/dashboard/masters#index
                           POST   /:master_url/dashboard/masters(.:format)          main/dashboard/masters#create
 new_main_dashboard_master GET    /:master_url/dashboard/masters/new(.:format)      main/dashboard/masters#new
edit_main_dashboard_master GET    /:master_url/dashboard/masters/:id/edit(.:format) main/dashboard/masters#edit
     main_dashboard_master GET    /:master_url/dashboard/masters/:id(.:format)      main/dashboard/masters#show
                           PATCH  /:master_url/dashboard/masters/:id(.:format)      main/dashboard/masters#update
                           PUT    /:master_url/dashboard/masters/:id(.:format)      main/dashboard/masters#update
                           DELETE /:master_url/dashboard/masters/:id(.:format)      main/dashboard/masters#destroy
                      main GET    /:master_url/:action(.:format)                    main/sites#:action
                      root GET    /                                                 main/sites#index

这是 main / dashboard / masters_controller.rb

class Main::Dashboard::MastersController < ApplicationController
respond_to :html, :js
before_action :all_masters, only: [:index, :create, :update, :destroy]
before_action :set_master, only: [:edit, :update, :destroy]
before_action :init_master
layout 'main'


def new
    @master = Master.new
end
def create
    @master = Master.create(conf_params) 
end

def update
    @master.update_attributes(conf_params)
end

def destroy
    @master.destroy
end

private
def all_masters
    @masters = Master.all
end
def set_master
    @master = Master.find(params[:id])
end
def conf_params
    params.require(:master).permit(:title,:url)
end
def init_master
    @master_url = Master.find_by_url(params[:master_url])
  end
end

关键是我想创建一个关于多站点的应用程序，所以：main命名空间被一个从Master的表中获取的动态URL替换。感谢this post earlier这个问题解决了，但我在主控制器视图中部分渲染表单和链接时遇到了新的问题，我使用ajax为每个链接点击并形成发布的btw，但我认为这个ajax方法不应该破解任何东西。

主要/仪表板/主人/ index.js.erb的

$('#content').html("<%= j (render 'index') %>");
$('#master-list').html("<%= j (render @masters) %>");

... / _ index.html.erb

<!-- Page Heading -->
<div class="row">
    <div class="col-lg-12">
        <h1 class="page-header">

            <%= link_to new_main_dashboard_master_path, remote: true do %>

        <div id="form-master" style:"display:none;"></div>
    </div>

</div>
<!-- /.row -->

... / _ master.html.erb

从这里我尝试编辑路径：edit_main_dashboard_master_path（编辑），它打破了错误消息所需的id，所以我提供master_url.url，奇怪的是错误消失了

<tr>
  <td><%= master.id %></td>
  <td><%= master.title %></td>
  <td><%= master.url%></td>
  <td>
    <center>
    <%= link_to edit_main_dashboard_master_path(@master_url.url, master), remote: true do %>
      <button class="btn btn-primary btn-xs">Edit</button>
    <% end %>
    <%= link_to main_dashboard_master_path(@master_url.url, master), remote: true, method: :delete, data: {confirm:  'Are you sure?'} do %>
      <button class="btn btn-danger btn-xs">Delete</button>
    <% end %>
    </center>
  </td>
</tr>

... / _ form_master.html.erb

这是现在存在的错误，当我创建新主服务器时它成功运行，但当我点击link_to编辑表单时不会显示错误ID ，然后当我点击链接删除时，它成功销毁 ..

<div class="panel panel-default">
    <div class="panel-heading">
        <h3 class="panel-title"><i class="fa fa-pencil fa-fw"></i>Add/Edit Conference</h3>
    </div>
    <div class="panel-body">
        <%= simple_form_for [:main,:dashboard, master], remote: true do |f| %>
            <%= f.input :url, label: 'URL' %>
            <%= f.input :title, label: 'Title' %>
            <%= f.button :submit %>
        <% end %>
    </div>
</div>

发出错误消息

任何帮助表示感谢顺便说一句，即时通讯使用Rails 4.1

Answer 1

好的，这个问题通过改变来解决了编辑link_to路径，使用：

link_to edit_main_dashboard_master_path(@master_url.url, master), remote: true do

或

 link_to :controller=>"masters",:action =>"edit",:id => master do

这两行都将返回正确的路径，因为这个问题使用嵌套命名空间，删除'Edit'参数会导致错误返回Stringify键，无论如何，感谢@Pavan

Answer 2

这里的问题相同。鉴于命名空间是＆＃34; ns＆＃34;。以下内容：

= link_to "User detail", @user

或

= link_to "User detail", ns_user_path(@user)

将生成此错误：

ActionView::Template::Error: No route matches {:action=>"show", :controller=>"ns/users", :id=>nil, ...

解决使用：

= link_to "User detail", ns_user_path(id: @user.id)

我希望能有所帮助。

无路由匹配：使用嵌套命名空间时缺少必需的[：id]
