Rails button_to因存在的路径不存在而失败 [英] Rails button_to fails with path doesn't exist for a path that exists

问题描述

编写我的第一个非常简单的Rails应用程序，一个简单的管理应用程序来跟踪我们某个部门的工作。生成的人员索引页面上具有link_to以添加新人员。我尝试将其更改为button_to，但未能说明路径/ people / new不存在，尽管显然如此，因为link_to移至同一位置。

Writing my first, very simple Rails application, a simple admin app to track work for one of our departments. The generated index page for people has a link_to on it to add a new person. I tried to change that to button_to and it fails saying the path /people/new doesn't exist, though obviously it does since link_to goes to the same place.

我正在使用Rails 3 / Ruby 1.9.2。我在/app/views/people/index.html.erb页面上有以下代码：

I'm using Rails 3/Ruby 1.9.2. I have this code on my /app/views/people/index.html.erb page:

<%= link_to 'New Person', new_person_path %>
<%= button_to "New", :controller => "people", :action => "new" %>

link_to有效。 button_to失败，因为：

The link_to works. The button_to fails with this:

路由错误
没有路线匹配 / people / new

Routing Error No route matches "/people/new"

也尝试过

<%= button_to 'New Person', new_person_path %>

相同错误。

推荐答案

button_to 默认为post方法。尝试放入：method => ：get 在那里。这就是为什么 link_to 起作用的原因。

button_to defaults to the post method. Try putting :method => :get in there. This is why link_to works.
