我如何为部分视图编写动作方法？

Question

我渲染的视图部分是这样的.

<%= render(:partial => "index" ,:controller=>"controller_name") %>

所以这将部分呈现controller_name/_index.html.erb

这是我的疑问.我能为这个_index写一个动作方法吗？这样的事情？

class ControllerNameController < ApplicationController
  def _index
  end
end

谢谢.

Answer 1

不,这应该是

class ControllerNameController < ApplicationController
  def index
   render :partial=>'index'
  end
end

编辑:详细解释我的答案 - 当你编写一个方法method_name而你没有render(redirect_to)任何东西时,控制器method_name.html.erb默认会查找页面.

但是,使用render :partial如下所示,该操作将与partial一起使用.

例如

class ControllerNameController < ApplicationController
  def some_method_name
   render :partial=>'index'  #look for the _index.html.erb
  end
end


class ControllerNameController < ApplicationController
  def some_method_name
   render :action=>'index'  #look for the index.html.erb
  end
end


class ControllerNameController < ApplicationController
  def some_method_name  #look for the "some_method_name.html.erb"

  end
end
