erb - Rails 3 render action from another controller

Question

I need to render another controller action <%= render "controller/index" %> and i get this error

Missing partial controller/index with {:formats=>[:html], :locale=>[:en, :en], :handlers=>[:rjs, :rhtml, :rxml, :erb, :builder]} in view paths "/path_to/app/views"

how can i render another controller action into a view but without sending an redirect to the client ? I've tried

<%=render :action => "index", :controller=>"controller" %>

but it seems that is not working.

Try to render template:

<%= render :template => "controller/index" %> 

Or file:

<%= render :template => "#{Rails.root}/app/controllers/controller/index" %> 

And I believe you should render it through controller, as far as it is more convenient:

def your_action
  ...
  render :action => :index
end
