The "update" action of my controllers and under certain circumstances creates a xml file on the filesystem. Using an after_filter that only gets called after the update action I create the XML file. Problem is, I get a DoubleRenderError because the update action either calls redirect_to or render. I can get around the render call by calling performed?() but the call to redirect_to always chokes the rendering of the xml file. Any ideas on how I can achieve this behaviour ? Or is there a more railish way to do the same thing ? --...

I have a custom authentication plugin that redirects users to a login site if they aren''t already authenticated and their session hasn''t timed out. I had things working fine with straight http requests, but wanted to add support for ajax requests. I thought this would be a simple matter of replacing all of my "redirect_to <blah> and return false" calls with

The DoubleRenderError exception recently introduced is forcing me to go back and rewrite my apps authentication handler. Before I could do a redirect right in the middle of a request. Whatever was happening after that went unnoticed, I assumed it was simply ending the request after the redirect was called, but apparent...

...partial that is sent to a web service. Here''s the code: class MyController < ApplicationController after_filter :post_to_webservice def show # show logic end def post_to_webservice stuff = render_to_string :partial => ''stuff'' webservice_post(stuff) end I get a DoubleRenderError in the after filter. As I understand it, the ''show'' action will be rendered, but won''t be sent to the browser until the after filter is called. Because the ''show'' action is already rendered (but not sent), we get a DoubleRenderError when render_to_stri...

...irect_to, is that possible? My specific use case is that I want to change the default redirection of "Login Engine" method signup, but I am seeing no other way then copy/past and change the parameters of redirect_to.

...s, looking for a module named Rendering in the ActionController namespace, since that is the namesapce that Base is defined in??? Well, ActionController module does define a module named Rendering: module ActionController module Rendering def render(*args) raise ::AbstractController::DoubleRenderError if response_body super self.content_type ||= Mime[lookup_context.rendered_format].to_s response_body end So now the method render(*args) is included in the Base class as an instance method. So when we call, for example, (hypothetically) ActionView::Base.new.render :action =&...

Is there a way to suppress the Double Render Error: "ActionController::DoubleRenderError. Render and/or redirect were called multiple times in this action.

I was trying to run the code in the page 149 and a DoubleRenderError shows up at the ''get'' line in the following code: def test_index get :index assert_response :success end I''ve read about DoubleRenderError, but they talk about redirect_to, but not about get method.

...uccess_controller, :action => @success_action) end In my action, if I do nothing unusual, then I expect to render to the regular place. If I override @success_controller and/or @success_action, then my action code can set up the success target. Unfortunately, when I try to do this, I get a DoubleRenderError, which I am sure is because the default render is already done in my action before I attempt to do either render in the after filter. Can this be done, or do I have to resign myself to only _setting_ the target in the after_filter, and then doing the rendering in the action method itself? Tha...

If I do: script/generate controller Photo I get a controller named photo_controller. OTOH, if I do: script/generate scaffold Photo I get a controller named photos_controller. (Note that the controller name is pluralized). I realize that I''m specifying the controller name explicitly in the first case, but it seems odd to me that the scaffold command generates a pluralized
