ROaR: A Ruby on Rails Podcast
I''m starting a new podcast to cover some of the hot topics going on in Rails. Half news, half interactive, all community. As always, the first episode kinda sucks but I''m looking forward to feedback from all of you on how to make it better. http://www.simiancodex.com/roar/ or for iTunes people http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=163609703 Michael

Patch submission question.
DHH asked for more documentation. Are those patches submitted indivdually per method or per module documented? Or are they submitted as some giant patch? Michael Genereux SimianCodex

How to determine if an object has just been created
Is there a built-in way to determine if a model object has just been created (ie. this object was the one that was originally persisted)? I can''t see it anywhere in the AR code, but thought I''d check. I want something like: p = Person.create p.original_instance? # true Is this built-in or should I just patch AR? -Jonathan.

Validation errors in has_one/belongs_to relationships.
I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

after_create and has_one association bug?
Hello, I''ve come across an issue that I''m sure is a bug when using after_create with a has_one association, but I''m not 100% certain if I''m missing something. This is pretty much exactly the code I''m using. Two simple classes (Account and Contact) and I create the contact after I create an account (via after_create). I''m not passing in a

Basic Relationship Problem
I''m trying to do a basic relationship and it''s not working the way it should. The data model is obviously a test database as the fields are minimal. In irb I do the following: >> user = User.create(:name => "shawn") => #<User:0x259ceac @errors=#<ActiveRecord::Errors:0x259c3a8 @errors={}, @base=#<User:0x259ceac ...>>,

how to make field in model immutable after create
Hello everyone! I want to have login field in User model which is set only once (on create), and then it should fail validation if the value is changed. How can I do this? I dig around for validation and tried def after_validation_on_update unless User.find_by_login(:login) errors.add(:login, "is immutable. You can''t change it") end end in model, but somewhat it

Comments wanted about spec''ing out a couple controller methods
(oops, accidentally sent this to the rspec-devel list, sorry about that) Could someone help me spec out these Rails controller methods? I don''t know where to get started, especially with the transaction stuff. Or, if anyone else could suggest ways I could improve the code, that would be great as well. Puzzle has_one Media. Both are AR model objects. class PuzzlesController <

[TIP] Ensure your test data is valid
Recently I wanted to check that my test data was valid. Seems like a reasonable thing to want to do so I thought I''d share the rake task. Add this code to a rake file in lib/tasks and run with rake db:fixtures:validate. It will print out the class, record id and error messages for any model objects that fail validation. Enjoy! -Jonathan. -- namespace :db do namespace :fixtures do

uh... fixtures?
RSpec-ers: I''m aware this is quite the FAQ. I have probably asked it myself, but I just can''t Google up anything but others asking it. I grabbed the source to Beast, to use as a Rails project uninfluenced by me, or RSpec. Then I installed the CURRENT version of RSpec and rspec_on_rails, and set up a model spec on Post. Here''s the spec_helper.rb lines:

Using :include with has_one vs. has_many
While I''m happy to continue talking about the vagaries of Rails deployments, I also need to actually build apps. :) I may have discovered a bit of a problem with :include as it applies to has_one associations. First, let me say that I''m a big fan of :include for reducing the number of SQL calls. There are times when I wish it could go more than 1 step away from the parent

can I fake has_one :through?
I''m having a difficult time wrapping my head around a set of models and their associations and seeing how they map into Rails. I''ll try to lay out my problem using the has_many and belongs_to structures. I have a RuleSpace, a Rule, and a Subject. A RuleSpace has_many Rules A RulesSpace has_many Subjects through Rules A Rule belongs_to (many) RuleSpaces A Rule has_many
