我不小心调用git rm ./ -r了我的工作目录并删除了我的所有代码。没问题，我只是打电话git pull来获取最新的代码更新，但是现在我不断收到来自设计的路由错误。

之后我不得不打电话bundle install。从这里开始，我不断收到错误：

Routing Error

No route matches {:controller=>"devise/registrations"}
Try running rake routes for more information on available routes.

所以我做的第一件事就是跑去rake routes看看这条路线是否存在并且它确实存在：

             members_ban GET    /members/ban(.:format)         members#ban
           members_unban GET    /members/unban(.:format)       members#unban
                 members GET    /members(.:format)             members#index
                         POST   /members(.:format)             members#create
              new_member GET    /members/new(.:format)         members#new
             edit_member GET    /members/:id/edit(.:format)    members#edit
                  member GET    /members/:id(.:format)         members#show
                         PUT    /members/:id(.:format)         members#update
                         DELETE /members/:id(.:format)         members#destroy
        new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
            user_session POST   /users/sign_in(.:format)       devise/sessions#create
    destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy
           user_password POST   /users/password(.:format)      devise/passwords#create
       new_user_password GET    /users/password/new(.:format)  devise/passwords#new
      edit_user_password GET    /users/password/edit(.:format) devise/passwords#edit
                         PUT    /users/password(.:format)      devise/passwords#update
cancel_user_registration GET    /users/cancel(.:format)        devise/registrations#cancel
       user_registration POST   /users(.:format)               devise/registrations#create
   new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
  edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                         PUT    /users(.:format)               devise/registrations#update
                         DELETE /users(.:format)               devise/registrations#destroy
                    root        /                              home#index

我将以下代码添加<%= link_to "New", new_user_registration %>到我的主页视图文件中，以查看是否可以获得更多信息：我收到以下错误：https ://gist.github.com/anonymous/5165745

我的路线文件：

Eveco::Application.routes.draw do

  get 'members/ban'
  get 'members/unban'
  resources  :members
  devise_for :users
  root :to => 'home#index'
end

扩展：所以我通过控制台和错误日志追踪了问题：

Started GET "/users/sign_up" for 127.0.0.1 at 2013-03-14 23:51:38 +0100

  app/views/layouts/application.html.erb:27:in `_app_views_layouts_application_html_erb__58597651_53376372'

我为我的应用程序实现面包屑的糟糕方式似乎存在问题。基本上我只想在其中显示控制器和方法，所以我使用它：

<div class="row">
    <div class="span12">
        <ul class="breadcrumb">
          <li><%= link_to "Home", root_path %> <span class="divider">/</span></li>

          <% if params[:controller] != 'devise' && params[:controller] != 'users' %>
              <% if params[:controller] != 'home'  %>
                  <li>
                    <a href="#">
                    <%=
                        link_to params[:controller].to_s.capitalize,
                                :controller => params[:controller]
                    %>
                    <span class="divider">/</span>
                  </li>
                  <li class="active">
                    <%= params[:action].to_s.capitalize %>
                  </li>
              <% end %>
          <% end %>

        </ul>
    </div>
</div>

如果我从应用程序中删除这个部分，路由就像一个魅力。然而现在它提出了一个新的问题。

根据这个问题，它可能是命名空间的问题。

基本上，我认为这params[:controller]显示为/devise/registrations因为如果您查看它，这就是您的路线设置方式（注意最后一列），但是您已将其映射到，users因此您必须将其用作控制器：

cancel_user_registration GET    /users/cancel(.:format)        devise/registrations#cancel
       user_registration POST   /users(.:format)               devise/registrations#create
   new_user_registration GET    /users/sign_up(.:format)       devise/registrations#new
  edit_user_registration GET    /users/edit(.:format)          devise/registrations#edit
                         PUT    /users(.:format)               devise/registrations#update
                         DELETE /users(.:format)               devise/registrations#destroy

如果您能以某种方式使用 url 助手，也许会更好。也许创建一个将面包屑文本映射到 url 路径的哈希。
