创建新rails操作不起作用？ [英] Creating new rails action doesn't work?

问题描述

我有一个控制器Apps。它由一个动作索引组成。现在我想添加一个名为购买的新操作：

  def buy 
 respond_to do | format | 
 format.html 
 end 
 end 
  

.html.erb到视图，但是当浏览到/ apps / buy时，我会收到以下消息：

 未知操作 - 在我添加此路线的路线中找不到AppsController 
  

  match'/ apps / buy'，：controller => 'apps'，：action => 'buy'
  

提前感谢！

解决方案

这个网址被标准的 / apps /：id 路由捕获，我假设你也有

<$>

p $ p> match'/ apps / buy'，：controller => 'apps'，：action => 'buy'
资源：apps


请记住，路由按顺序执行

一个更简单的方法是@Ryan建议在资源中添加一个集合路由：

 资源：apps，：collection => {：buy => ：get} 
  

i have a controller "Apps". It consists of one action "index". Now I want to add a new action called "buy":

def buy
  respond_to do |format|
    format.html
  end
end

i added a buy.html.erb to the views, but when browsing to /apps/buy, i get following message:

Unknown action - The action 'show' could not be found for AppsController

in the routes I added this:

  match '/apps/buy', :controller => 'apps', :action => 'buy'

thanks in advance!

解决方案

The url is being caught by the standard /apps/:id route, I assume you also have resources :apps in your routes?

Simply place the buy route first:

match '/apps/buy', :controller => 'apps', :action => 'buy'
resources :apps

Bear in mind that routes are executed in the order they are defined, so the specific ones need to precede the general.

A simpler approach as @Ryan suggests is adding a collection route to the resource:

resources :apps, :collection => { :buy => :get }
