All - I''m completely new to RoR and also new to programming in an MVC structure... The Pragmatic Programmers guide to Rails says, temptingly: "After filters can be used to modify the outbound response, changing the headers and content if required. Some applications use this technique to perform global replacements in the content generated by the controller?s templates (for

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

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?

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

Hi, I was wondering if there is a feature or construct in rails that is guaranteed to run after an action like an around_filter (or after_filter) but will still run regardless of a broken filter chain or thrown exception? Currently I have an around filter setup, and I really require the after part of the filter to run, although if the filter chain is broken via cacheing or an exception is

Hi Everyone, I tried doing this and it''s not working as I would expect it, but I''m not sure if it''s even possible. I have an app that generates and image on request and displays it to the user. To cut back on storage, and some security, I''d like the app to receive the view request, render the image, display it, then delete the file. I know this isn''t

In the Rails Recipes book the recipe "Keeping track of who did what" explains how to do decoupled observing of models. In my application I''d like to do a similar thing but watching the controllers. For example, when somebody hits the login method of the Security controller, I''d like to make a note of it. In this case I could observe the User model and watch for

...uot;before_filters") instead of before_filters. Similarly, use read_inheritable_attribute("included_actions") instead of included_actions. This is bad because now my code is tied to an implementation detail which would normally be hidden. Incidentally, the same bug also occurs in after_filters and excluded_actions.

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

Hi all how to make a WML view for rails pages? I''ve tried to create like: <wml> <card> CONTENT </card> </wml> but my phone says unsupported content type... thanks -- Posted via http://www.ruby-forum.com/.

I am using mongrel to serve static as well as dynamic pages. The static page''s controller contains the following line of code: after_filter {|c| c.cache_page} This code caches that page as a static html page that does not have to be rendered form multiple files (the view and layout). I got the idea to do this form the rails recipes book. It definitely cached the pages. Wen I make

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

Hello everyone! I''m trying to create an after filter for all my actions in all controllers. I put it in application controller (application.rb). class ApplicationController < ActionController::Base after_filter :tidyit def tidyit xxxx # syntax error - intentionally end end I have a Example (example_controller.rb) controller with index action. class

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

Now that controllers can have multiple view paths I''ve been playing with themes over the weekend. Running into a view issues. I have a before_filter in the ApplicationController that calls prepend_view_path to add the path of my theme. I even log the view_paths in an after_filter to make sure it made it all the way through. The output looks something like:

I know I''ve seen this before, but I can''t find it and Google hasn''t been a help... >From within a controller method, how can I find the name of the requesting controller?
