I'm interested in setting up my own website-based game (PBBG) as a hobby. Traffic shouldn't be too much, a couple of dozen users at a time on average. From all the reviews I've seen, Ruby on Rails is the best way to go as far as coding and platform. As far as OS goes, I've only used Ubuntu in the past and, while it worked smoothly, I ...
One trick I have found very handy in rails application programming is that class_eval can be used to create methods on the fly. I'm starting to get into testing now and I wonder if a similar idea could be used to generate tests. For example, I have a before_filter to require a user to be logged in for all of the actions in a controller...

Hi, I've got a requirement to specify a named route in a Ruby on Rails project that returns the public/404.html page along with the 404 server response code. Leaving it blank is not an option, please don't question why, it just is :) It absolutely must be a named route, or a map.connect entry would do. Something like this would be g...
In the User model I have two accepts_nested_attributes_for: :details (which is has_one association) and :membership_orders (has_many). For :details I have: attr_accessible :details_attributes But for the membership_orders I can't have so simple accessor, because I want to protect it from the normal user, but make it accessible for th...

I'm trying to either get all of a user's boards at once with a way to differentiate what role a user has on each board, or make three separate calls to get boards that a user is a ...

Let's say I have a User model and an Address model: - A User can have many Addresses - One address is also linked as the "primary_address" Let's say I have the following in my...

I have a gem that uses some of the Rails libs, including action_view and active_controller. Though I require those libs, all tests fail when trying to call some has_text? method, which (as I found out) is part of'rexml/element' lib. Here's what I get: undefined method `has_text?' for "<b>Hello,<i>world</b></i>":String Requiring 'rexml...
