ActiveRecord collection_select and has_and_belongs_to_many
Hello everyone, first post to the list and a relative newbie to Rails development. Done quite a bit of JSP, PHP, HTML, XML etc and thought I would kick the tires on Rails to see if it can speed up development for internal applications.

The following example illustrates the problem. I have two tables: create_table "blogs", :force => true do |t| t.column "name", :string end create_table

New Technique: Subsets of has_many Associations
I just now thought of this, and sure enough it works like a charm (at least so far in my limited testing): has_many :events, :dependent => :delete_all has_many :upcoming_events, :class_name => "Event", :conditions => "date > NOW()" The purpose of this is that it makes eager loading of subsets of associations possible without replacing all the magic of the

I have one table, called "people". Within this table, there are type "users", "managers".... etc. So, basic STI. Now, I want a "user" to have one manager, but a "manager" to have many "users". Since I don''t want to use HABTM... how do I set this relationship up seeing that :has_one, :belongs_to and :has_many don''t

Limited eager loads and conditions on the eager tables
Hi, Why are limited eager loads and conditions on the eager tables incompatible? Doing a find(:all) without :include causes a select * query to be generated, which means the id fields everwrite each other if associated tables are included using :joins. But using :include, if conditions are placed on the tables listed in :joins then Rails throws an exception when :limit is included too.

Problems with STI in has_many/belongs_to in Rails 1.1
I have a problem that surfaced in my attempt to upgrade my application to Rails 1.1. We have a STI model on the "belongs_to" side of a has_many/belongs_to relationship. All my unit tests for this model pass, and the relationships all seem to work fine. But in my functional tests, I''m getting errors. I''ve traced it back into the call to the has_many
