I am using a serialized attribute in one of my models The serialized data is in the form of an array. I want to have a text_tag for each element contained in my serialized attribute.

Hello. In one of my ActiveRecord models I specified a a serialize field: serialize :settings MyModelSettings If I understand the documentation correctly this restricts settings to the class MyModelSettings.

Hello, I''m setting up an authentication module that will be called from application.rb. I want to save a rrequest.request_uri into a session to be used as a place holder that will take users back to the page they were on before they logged in.

Having implemented a GC for HLVM, I am now turning my attention to implementing a GC that supports parallelism. To do this, I would like to use atomic instructions as well as mutexes. What is the status of LLVM's atomic instrinsics (e.g. CAS)? Is anyone using them in real projects? I realised that an obvious test would be to compile some simple example programs with llvm-g++ instead of

Is there a method to return a hash of the route configuration based on a path? For example: magic_method(''/my_controller/my_action/my_id'') => {:controller => ''my_controller'', :action => ''my_action'', :id => ''my_id''} Thanks!

Hey, Is is possible to get the full URL (''http://www.sender-domain.com/links/list.html'') from where a user was sent to my site (www.my-domain.com/controller/action) e.g. by clicking on a link? (I read about something called a ''request'' object, I don''t know what it is or does, is that what I''m looking for? I''m very new to Rails

Hi. I would like to set @request.env["HTTP_REFERER"] in an integration test, but due to its nature, I would naturally set this value to the previousle request url. How do I do that. Thanks. Jarl

Howdy, I''m using Apache 2.2 + Mongrel with great success, using the sample configs from the Mongrel site. We have some MP3s on the site and recently someone has been stealing them and basically leaching them from the site, linking to them from an off-site location. I''ve been trying to modify my Apache conf to check the referrer and adjust accordingly as below but no

I am working with the authlogic gem and trying to create a simple login test from cucumber features. The feature statement is: Given the user is not logged in The step definition for this is confounding me. In the application_controller the authlogic tutorial recommends the following: private def require_user unless current_user store_location flash[:notice] =

Hello I have a rails 3 app and I am trying to implement the redirect back action at access denied for cancan. If I try this in my application_controller: rescue_from CanCan::AccessDenied do |exception| redirect_to :back end It gives the following error: No HTTP_REFERER was set in the request to this action, so redirect_to :back could not be called successfully. If this is a test, make sure

Hey guys, Ok, basically I coded a ruby on rails CMS to manage a bunch of media files. I am finding that a lot of people are "hot linking" to these media files and would like to prevent this to save bandwidth. Usually in the past, it hasn''t been a problem, I would add something like the following to my .htaccess file RewriteEngine on RewriteCond %{HTTP_REFERER} !^$

Hello, we want to read the referer URL from the HTTP headers, in order to be able to track where someone is coming from, in a Rails application. As I can see in the source, Mongrel doesn''t even parse the HTTP_REFERER field from HTTP requests. This would make a useful feature, I guess. Apart from that, Mongrel is (IMHO) simply the best solution for deploying Rails - keep on going!

Slowly figuring out how to get my SaltedHashLoginGenerator stuff working. The wiki page says to put "before_filter :login_required" in the user (my "user" is "member") controller or in ApplicationController. However, wherever I put it I get NoMethodError. The rest of the SHLG stuff seems to be working... or at least I could get to the signup page, register, and

I have a partial, it''s a shopping cart display, it''s designed to appear on several different pages of my site. One of the buttons on the shopping cart empties the cart, and then I want the calling page to redisplay. In other words, the cart controller needs to return the visitor to the same page -- however since the cart could appear on any given page, this has to be

Hello I''m using the login generator on my application, and I found a problem with it. My application is a rack inventory thing, which shows a rack with machines and KVMs and you can click on a rack item to show/edit/destroy it. The edit and destroy actions are protected by the login generator. Now say a user clicks on "destroy" for some machine. He''ll be shown the
