Rails 3.1.rc1 and accept_nested_attributes_for

Question

I have the following models:

class Survey < ActiveRecord::Base
  set_primary_key :survey_id # I'm using external DB
  belongs_to :user #UPDATED
  has_many :questions, :dependent => :destroy
  accept_nested_attributes_for :questions
end

class Question < ActiveRecord::Base
  set_primary_key :question_id # I'm using external DB
  belogns_to :survey
end

If I go to rails console and save a model:

>> params = {"title"=>"Survey 1", "questions_attributes"=>{"0"=>{"title"=>"Question 2"}}}
>> survey = User.first.surveys.build(params) #UPDATED
>> survey.questions.size
=> 2
>> survey = User.first.surveys.new(params)
>> survey.questions.size
=> 1

Rails is duplicating question resource on surveys. Maybe is it a Rails 3.1 bug? The code is similiar to railscasts episode 197.

Ok, the problem is in the build function because using new it works well. — beagleknight

Sorry, I do some changes to the code because the original code is quite different. — beagleknight

...and belogns_to should obviously be belongs_to. (it might help other n00bs like me if you corrected the code) — Dominic Sayers

It was fixed in this commit.

The fix is present Rails 3.1.0rc2, so if you update your Rails version in your Gemfile:

gem 'rails', '3.1.0.rc2'

And run

$ bundle update rails

It should work as expected.
