Rails - 没有路由匹配{：controller =＆gt;“engage / home”}＃＆lt; ==导航到localhost时出错：3000 /搞
首先，事实：
当我导航到localhost：3000 /搞时，我收到以下错误：
ActionController::RoutingError at /
No route matches {:controller=>"engage/home"}
这是我的routes.rb文件：
Kt::Application.routes.draw do
#resources :authentications
resources :paths
mount Engage::Engine => '/engage', :as => 'engage'
resources :comments do
member {post :forresource}
end
resources :resources do
member { post :vote }
collection {get :search}
end
devise_for :users
resources :userResourceView
resources :learningPaths
get "home/index"
devise_scope :user do
get "/login" => "devise/sessions#new"
end
devise_for :user, :path => '', :path_names => {:sign_up => "register" }
match '/user_profile', :to =>'users#index'
get 'tags/:tag', to: 'resources#index', as: :tag
match '/auth/:provider/callback' => 'authentications#create'
match '/auth/:provider/failure', :to => 'authentications#failure'
#match '/auth/:provider/callback?error_reason...', :to => 'profiles#failure'
match '/resources', to: 'resources#create', :via => :post
match 'contact' => 'contact#new', :as => 'contact', :via => :get
match 'contact' => 'contact#create', :as => 'contact', :via => :post
match '/forums' => 'forums#index'
root to: 'home#index', :as => :home
当我运行rake路线时，我得到以下内容：

此外，该错误提到了app / views / shared / _header.html.erb。这是该文件：
<div id="header">
<div id="logoText">
<%= link_to "Knowledge Thief", url_for(:action=>"index", :controller=>"home") %>
</div>
<div class="signin">
<a href="#">
<div class="notifications unread">
3
</div>
</a>
<% unless current_user.nil? %>
<%= link_to "#{current_user.email}", url_for(:action=>"user") %>
<% else %>
<%= link_to "Sign In", url_for(current_user) %>
<% end %>
<%= link_to image_tag("downArrow.png", :style => "height:5px;margin-left:3px;vertical-align:middle;"), url_for(current_user) %>
</div>
</div>
到目前为止我已采取的步骤（将会更新）：
- 确保捆绑安装
- Ran rake db：reset
- Ran rake db：migrate
- 问我的团队两天前和现在之间可能发生了什么。我将通过git log等查看。
现在，我可以看到/参与被引导到参与，但这个/家在哪里？不应该/只是去参与/主题#index？
1 个答案:
答案 0 :(得分：2)
您的主应用程序中是否设置了家庭控制器？原因在于 _header.html.erb 文件，您使用链接来指定家庭控制器的操作。
我猜你正在使用主应用程序的布局/模板来渲染引擎的视图。 _header.html.erb 也是呈现引擎视图的模板的一部分。
可挂载引擎在轨道中的工作方式是，如果要访问主应用程序控制器/操作的路径，则需要在 main_app 上调用。因此，您可以将 link_to 行更改为：
<%= link_to "Knowledge Thief", main_app.home_path %>
