RoR路由错误：从link_to构建的URL，路由出现在rake路由中

Question

的routes.rb

resources :project_associations, :only => [:update]

rake routes

project_association PUT    /project_associations/:id(.:format)  {:action=>"update", :controller=>"project_associations"}

ERB

<%= link_to membership_command[:text], project_association_path(membership_command[:id], :command => membership_command[:command])%>

结果HTML

<a href="/project_associations/2011?command=suspend">Suspend</a>

点击结果： 路由错误 没有路线匹配“/ project_associations / 2011”

我踢了服务器，结果相同

提前感谢您的任何帮助。

Answer 1

将其添加到link_to：:method => :put。

所以：

    <%= link_to membership_command[:text], project_association_path(membership_command[:id], :command => membership_command[:command]), :method => :put %>
