ruby-on-rails - 无法找到 ID ="your_question"

Question

我的错误是:

 Couldn't find Question with 'id'=your_questions" 
 and 
 ActiveRecord::RecordNotFound in  QuestionsController#show

我应该怎么做才能修复它？

def show
  @question = Question.find(params[:id])
  @answer = Answer.new
end

在第二行它指出了错误所在。

编辑:

索引 View 文件

 <%= form_for(@question) do |f| %>
<%= render 'common/form_errors', object: @question %>

<p>
    <%= f.label :body, "Question" %><br />
    <%= f.text_field :body %>

    <%= f.submit "Ask a Question" %>
</p>
<% end %>


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'

  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/:id', to: 'questions#your_questions'
  get '/search', to: 'questions#search'

Answer 1

你提到你有这条路线:

get '/questions/your_questions', to: 'questions#your_questions

如果你也有像following the restful style这样的路线，你也应该有这样的东西:

get 'questions/:id', to: 'questions#your_questions'

或者资源调用。不管怎样，Rails 实际上是在尝试通过“your_questions”作为路线的 id 来访问您的 show Action 。像这样写这条路线:

 get '/questions/:id', to: 'questions#show

这意味着:“如果使用 GET HTTP 方法的请求遵循 url 'questions/:id'，则转到 Controller :questions 及其操作( Controller 中的方法)称为:your_questions”并传递到参数哈希URL 中 id 的值。
