Hey guys, I recently started with the 'Agile web development with Rails' book by pragmatic programmers after having some early experience with rails but wanting a more structured approach. I'm happily following the book when they ask me to make a controller admin so I can edit the standard CRUD product model I already created. Accordin...

This code in my view triggers an error: <% remote_form_for(mymodel) do |f| %> <%= f.error_messages %> (mymodel is not an ActiveRecord object) When I look at the error trace, I see this section which indicates that error_messages in the view translates into error_messages_for in the active_record_helper: C:/Ruby18/lib/ruby/gems/1.8...

When finding web hosting for Rails apps, the hoster must have support for ruby on rails -- that is evident. What about hosting for Django? What support does the hoster need to provide? Python, or more than just Python? This might seem like an obvious question, but I'm new to web development frameworks so I must ask :) ...

I'm fetching and manipulating XML from twitter and flickr in my rails app. The results appear on every page and the parsing is handled in the Application Controller with Hpricot and open-uri. This is my first experiment with action caching and it doesn't seem to be working. I'm in dev mode using WEBRick. Everything appropriate is set to...

On a Rails project, I'm using Sphinx together with Thinking Sphinx plugin. I index a table with an attribute :foo that is a float. My desired behaviour when sorting for column :foo would be that nil values always appear at the end of the list, e.g. id; foo (order foo desc) ------- 1; 5 2; 3 3; -4 4: -5 5: nil 6: nil id; foo (order f...
Can anyone suggest some troubleshooting approaches for getting IRBRC running under Win32? The rails console is an awesome tool and I'm attempting to extend it with more functionality. For instance, I would like the what_method gem to load automatically. The gem is installed but it does not load: C:\...\trunk>ruby script\console Loa...
Updated Appears to be a precedence error and nothing to do with the question I originally asked. See discussion below. Original question Is it possible to use active record associations in callbacks? I've tested this code in the console and it works fine as long as it isn't in a callback. I'm trying to create callbacks that pull ...
I tried to update the specs on a gem that didn't have a .specification file. 1. cd {application_home_directory} 2. rake gems:refresh_specs When I did, I received the recursive warning: config.gem: Unpacked gem in vendor/gems has no specification file. Run 'rake gems:refresh_specs' to fix this. I've also tried this, which also fail...
I've noticed some ruby gems have .specification files and others don't. If they're important, why are you not required (by whatever tool builds them) to provide one when you attempt to create your gem? ...
I like the idea of using submodules, but I am worried that I am leaving my code in someone else's hands. The main issue is that every time I deploy with capistrano, a new copy of the submodule is checked out since I am using: set :git_enable_submodules, 1 So what happens if someone commits broken code? Then I app breaks on deploy. ...
environment.rb starts with this: RAILS_GEM_VERSION = '2.3.2' unless defined? RAILS_GEM_VERSION require File.join(File.dirname(__FILE__), 'boot') Rails::Initializer.run do |config| Does this mean environment.rb starts first and calls boot.rb? ...
Let's say in a Rails app you have some gems that you use in your app (we'll call them "primary gems") and you have vendored them for portability. Let's say that those "primary gems" also require gems of their own - we'll call these "secondary gems". When you are setting up your environment.rb, you have to say: config.gem 'primary-gem...
