similar to: Looking for a way to avoid DoubleRenderError.

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

I have a common failure page that I may need to render to upon failing some test that occurs in an after_filter method. I''d like to use the after_filter to take over the control of the rendering, like so: def test_for_validity some_boolean = my_test return render(:action => ''disqualified'') unless some_boolean @success_controller ||= controller_name

I''m using render_to_string in an after_filter, which renders a 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

I want to be able to change the redirection url after I called redirect_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. This questions extends to render method as well, I want is to avoid DoubleRenderError exception. --

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 apparently it was going on and rendering the page. Why can''t a redirect

I''m not sure why this is happening, but if I do this in a controller unless @variation && @variation.quantity > 0 flash[:error] = "Sorry, that product is currently not available." redirect_to(:action => ''error'') and return end rspec tells me 2) ActionController::DoubleRenderError in ''The Carts controller with an

Hi all: I can''t make redirect_to to unlock the current iframe using {:TARGET => "_top"}. It always stays in the current frame. I checked the redirect_to code, it seems the method does not use "target". here is the source code of redirect_to from ActionController::Base def redirect_to(options = {}, *parameters_for_method_reference) #:doc: 753: case options

Hi everyone, i followed colins example and it worked perfectly but now i get this error ActionController::DoubleRenderError in UserController#login Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to

Greetings, I''ve got a rails app which is basically an admin interface to a xml dataset. Currently I''ve got rails rigged to call a function to spit the entire dataset to file with every change. This would actually be ok, its fairly infrequently updated, but when the dataset grows large the user sits there waiting for it to dump with no feedback as to whats going on. Oh yes,

Ok, I think I understand why RoR will flag an attempt double render in an action. What I don''t understand is the philosophy of render and redirect_to. Specifically, why isn''t a return implicit in both those methods? Or, I guess, more to the point ... what are the advantages of writing code in the action after a render/redirect_to? -- Posted via http://www.ruby-forum.com/. --

Hi! Is it possible to render the action within the after_filter method, or is the rendering performed before? I have something like this: class FooController after_filter :send def a @content=... end def b @content=.. end protected def send send_data(@content,...) end end However, when calling the action a or b, the @content doesn''t get sent, but instead

Hey all, I''d like to abstract the process of updating different portions of the page after an Ajax request has taken place. Rather than simply putting the extra view logic in the standard rjs template, it seems to give better separation if there is a split between the core view logic (ie, inserting a row in a table), and updating any associated portions of the page. Is this possible? I

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

Hello I would like to execute specific action rendering something into page after each of my ajax calls. In example I would like to update some div or display an alert. How I imagine it could work is as follows class ApplicationController < ActionController::Base after_filter :do_something_after_each_ajax_call def do_something_after_each_ajax_call if request.xml_http_request?

Hi, In my user_controller.rb, I have the following method, which is supposed to send the user to their profile, dependng on what "role" they are (the roles correspond to the other controllers: venue, band, fan): def login if request.post? if session[:user_id] = User.authenticate(params[:user][:login], params[:user][:password]) flash[:message] =
