In a view, render just returns a string and you don't need render_to_string (I don't think it even exists). In a controller render sets the response body (and calling it a second time raises a doublerendererror), so if you need to manipulate the rendered content in anyway (e.g. stick it in a json document) then you need to use render_to_string Fred > -- > Posted viahttp://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
