  • State changed from “new” to “incomplete”

  Use render_to_string :template => 'i_do_not_exists/index'

  What is the behavior in Rails 2.0.x ?

  I do NOT want to render just another template (without its action). I want to render another action. I have just checked and I see it is broken for RoR 2.0.2 and 2.1.0 as well. Therefore information displayed in api.rubyonrails.org is misleading and wrong (capitalization is mine):

  render_to_string(options = nil, &block) 
  
  Renders according to THE SAME RULES AS RENDER, but returns the result in a string instead of sending it as the response body to the browser. 
  

  # app/views/controllers/my_controller.rb:
  
  class MyController < ApplicationController
    def index 
      @slot = render_to_string :action => 'second'
    end
    
    def second    
      @var = 'World'
      render :text => 'It will never be displayed from host/my!' 
    end
  end
         
  
  # app/views/my/index.html.erb:
  
  Slot: <%= @slot %> 
           
  # app/views/my/second.html.erb:
  
  Hello <%= @msg %>! 
  
  

  Result at http://localhost:3000/my:

  Result:

  Slot: Hello !
  

  The @msg variable was not rendered at all. render :text was also ignored at all. It looks like render_to_string ignores Ruby code in the action.

  You cannot render another action. render_to_string is only for rendering templates. It will not call action code.
