Question

我收到一条错误消息，说它有

undefined local variable or method 'your_questions_path'

我的routes.rb文件：

Rails.application.routes.draw do
  get "/" => "main_app#index"
  get "/location" => "location#location"
  post "/location/index" => "location#index"
  get "/location/index" => "location#index"
  get "/location/directions" => "location#directions"

  root to: 'questions#index'

  resources :questions do
    collection do
      get :your_questions
    end
  end

  get '/logout', to: 'sessions#destroy', via: :delete
  resources :users, only: [:new, :create]
  resources :sessions, only: [:new, :create]
  resources :questions, except: [:new] do
    resources :answers, only: [:create]
  end

  get '/register', to: 'users#new'
  get '/login', to: 'sessions#new'
  get '/logout', to: 'sessions#destroy', via: :delete
  # get '/questions/your_questions', to: 'questions#your_questions' original
  get '/questions/:id', to: 'questions#show'
  get 'search', to: 'controller#action', as: :search

我的视图文件包含问题路径a.k.a app/views/layouts/application.html.erb

<div id="nav">
  <ul>
    <li>
      <%= link_to 'Home', root_path %>
    </li>

  <% if logged_in? %>
    <li>
      <%= link_to "Your Q's", your_questions_path %>
    </li>
    <li>
      <%= link_to "Logout (#{current_user.username})", logout_path, method: 'get' %>
    </li>
  <% else %>
    <li>
      <%= link_to 'Register', register_path %>
    </li>
    <li>
      <%= link_to 'Login', login_path %>
    </li>

我希望问题路径转到http://localhost:3000/questions/1

提前谢谢！

您定义的路线会创建以下路线：

          your_questions_questions GET    /questions/your_questions(.:format)           questions#your_questions
                         questions GET    /questions(.:format)                          questions#index
                                   POST   /questions(.:format)                          questions#create
                      new_question GET    /questions/new(.:format)                      questions#new
                     edit_question GET    /questions/:id/edit(.:format)                 questions#edit
                          question GET    /questions/:id(.:format)                      questions#show
                                   PATCH  /questions/:id(.:format)                      questions#update
                                   PUT    /questions/:id(.:format)                      questions#update
                                   DELETE /questions/:id(.:format)                      questions#destroy

顶部路线是your_questions路线，这意味着您需要使用：

your_questions_questions_path

这种情况正在发生，因为你已经在资源块中嵌套了你的路径，即。你有这个：

resources :questions do
  collection do
    get :your_questions
  end
end

如果你要到达这条路径，（运行rake routes）你需要使用questions_your_questions_path，但是因为你想要路由到类似http://localhost:3000/quesitons/1的东西，这是一个简单的'show'路径，由resources命令提供给您，而是将您的路径文件改为简单地说：

resources :questions

然后使用question_path(@question)，其中@question是控制器中设置的实例变量。

然而......也从您的代码中看，您似乎想要questions_path，因为这会提供index操作（问题列表）。然后，您可以在控制器范围内将问题集合添加到当前用户看到的那些......

即。

QuestionsController < ApplicationController

def index
  @questions = current_user.questions
end

（假设您的User has_many：问题）

未定义的局部变量或方法`your_questions_path＆＃39;
