找不到控制器的操作

Question

浏览完我的代码后，我有一个与原始问题不同的问题，而不是编写一个新问题。我将把旧的部分留在底部，并在这里发布新的问题。我这样做是因为它们密切相关。

新：

我收到一条错误消息，说

Unknown action

The action 'response' could not be found for CrawlerController

我会保持简单，但模型、控制器和路由的代码位于上一个问题的下面。

基本的总结是响应是 CrawlerController 中的一个定义，就像 add_Request 一样。 路由是这样匹配的：

  match  "/requests/new" => "crawler#add_Request"
  match 'requests/:id' => 'crawler#response'   

这是根据用户请求的控制器代码：

class CrawlerController < ApplicationController
def add_Request
@request = Request.new(params[:request])

respond_to do |format|
  if @request.save
    format.html { redirect_to(@request, :notice => 'Request was successfully created.') }
    format.xml  { render :xml => @request, :status => :created, :location => @request }

  else
    format.html { render :action => "new" }
    format.xml  { render :xml => @request.errors, :status => :unprocessable_entity }
  end
end
end

def response
  @request = Request.find(params[:id])
 respond_to do |format|
   format.html
   format.js { render :json => @request }
  end
end

def show
  @request = Request.find(params[:id])

  respond_to do |format|
    format.html # show.html.erb
    format.xml  { render :xml => @request }
    format.json{
      render :json => @request.to_json
    }
  end
end
 end

请重新检查控制器的代码，因为我可以看到它，

class CrawlerController < ApplicationController
  def add_Request
    @request = Request.new(params[:request])

    respond_to do |format|
      if @request.save
        format.html { redirect_to(@request, :notice => 'Request was successfully created.') }
        format.xml  { render :xml => @request, :status => :created, :location => @request }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @request.errors, :status => :unprocessable_entity }
      end
    end

    def response
      @request = Request.find(params[:id])
      respond_to do |format|
        format.json {render :@request.to_json}
    end
  end

因此缺少一端，并且您的 response 操作是在 add_Request 中定义的
