I''m having a problem with a has_and_belongs_to_many (habtm) association between two models with extra attributes. I''m writing a comic book database, and each issue has many creators on it. Thing is, some creators perform multiple duties. They may write one issue, draw another, etc. However, if I add a creator twice to an issue and try to delete it, it removes both creators:

Hi all, Thought I should say something - it''s been a little while. :) Anyway, I''m still futzing with how I want the Ruby API to look. The more I look at the Perl version, the more I think it was too faithful to the C API. Right now I''m looking at the trigger() method.

I''ve created a model, let''s just call it Person class Person attr_accessor :first_name, :lastname def full_name @first_name + " " + @last_name end end I''m using this in my Rails application. My Rails application does not use a database of any kind, and this model is obviously not a subclass of ActiveRecord::Base. I can''t unit test this

Hi, Another noob here I am afraid! I have a questuin about the current_user method that comes with AAA. I have AAA set up and working fine and if i put <%= self.current_user.login %> into a view it shows the login name as expected on the page.

Hi everyone, I''m currently finishing the planning phase of a small project I want to create.
