Change to set_fixture_class
So, I sat down to use set_fixture_class, and it bombed on the first thing I tried: set_fixture_class :content_drafts => "Article::Draft" I made a quick patch, and I''d appreciate a quick run through your tests to make sure it doesn''t disturb anything: http://dev.rubyonrails.org/ticket/4095 As I was typing this, I realized that the string gives us no benefits.

Polymorphic Associations
If anybody on edge familiar with this could help, that would be "great" :) I have different types of things I want to be "reviewable". So, instead of having a slew of HABTM... this new Polymorphic Associations schtick seemed like the best solution. I have everything setup as I thought it should be (so I think)... but it doesn''t appear to be working correctly. Here

STI, subclasses and callbacks
I have a STI class tree. I want to set some default values (calculated values so I can''t set it in the database as defaults) on every created instance regardless of what subclass is actually instantiated. So I figured adding a after_create callback in the top class in the hierarchy should do the trick. It seems it doesn''t get called :( Code: class SuperClass <

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

Multiple associations between tables - do they ever work?
This is really bugging me. How can I get a second association to work between 2 tables. I have two models, User and Article. A user has many articles, and an article belongs to one user. Then I have the "current article", which is a the article that the user is currently viewing/editing. I want to track/save this value, so they can come back to the same article if they log out

How painful is the 1.0 -> 1.1 upgrade going to be?
Does anyone have a sense for how painful the 1.0 -> 1.1 upgrade is going to be for existing apps? I''m finishing up my first real RoR application with Rails 1.0. I can live with it staying at that level, but I really want to use the has_many :through attribute to clean up some of my code. I''m not particularly interested in edge Rails, mainly because the documentation for

has_many :through failing to save changes
Hi all, I''m messing around with has_many, and has_many :through (on edge rails), using a join model. Branches and Projects join through ProjectsAtBranches. If I do @branch.projects, I can see the associated projects, and visa-versa, if I manually put them in the join table. But I cannot do @branch.projects << Branch.find(blah), or @branch.projects.clear, and then save the

Still Having Problems With :through When Going To Same Table... Help... please :-(
I am having a problem with doing a :through that goes back to the same table.

acts_as_paranoid and :include
Will the find from acts_as_paranoid filter down to an :include? For instance class parent acts_as_paranoid has_many: children end and class child acts_as_paranoid belongs_to :parent end Then if you Parent.find(:all, :include => children) you will get all the children if they are deleted or not. I guess the find that filters out the deleted_at is null does not filter down to the includes

suggest for "ambiguous column" when JOIN associated tables

You have record with self-referential joins CREATE TABLE keywords (id, group_id); class Keyword < ActiveRecord::Base belongs_to :group, :class_name => "Keyword", :foreign_key =>

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
