I really need help with Rubygems (that's the package manager for ruby). Since I'm behind a proxy, I've given up all hope of it working automatically, so I had to download a lot of packages manually and install them for rails to install. Now, I'm getting an error message: Rails requires RubyGems >= 1.3.2 (...) Once again, I manually dow...

I need some help refactoring this so it's not so burly. <% unless params[:order] != 'created_at' %> <%= link_to "Recently Posted", photos_path, :class => 'current' %> <% else %> ...

Hello, I am relatively new to ruby on rails, so this question might be easy. Rails does a lot of magic and I am not sure where to look up such things, because I don't know which part of the framework is to blame. I basically did the authlogic_example and fiddled around with the code afterwards. My routes.rb looks like this map.root ...

I'm writing an app that has a "wizard" type input section. Think MS Windows Installers. I'm having a hard time figuring out how the most RESTful way to do this with rails. I can make it happen in a non-restful way (already did for version 1 of the app), but I'm trying to be a little more idiomatic this time around. Here's the situati...

To give little more details, if I am accessing acme I don't want to see tags from xyz subdomain. I have looked into act-as-taggable-on, but the...
In an ActiveRecord model, is it considered best practice/necessary to use validates_presence_of when also using validates_length_of? For example: class Company < ActiveRecord::Base validates_presence_of :name validates_length_of :name, :in => 5..30 end To me, it seems redundant. Having a length between 5 and 30 means that the a...
I did some stuff to have to_param return a perma-url so I'd have seo friendly links. Upon creation and update it will generate and return the perma-url in a to_param method that I put in the model. However this causing me some grief in other areas. I have a form that looks like this: <% @apps.each do |app| %> <% fields_for "[id][...
