Padrino + FactoryGirl not performing Lazy Loading

Question

I'm developing my thesis on Padrino, using Active Record as ORM and FactoryGirl as Mocking framework.

I'm facing a strange behavior.

I've two models: User and Rate.

- User has a 'has_many :rates' association;
- Rate has a 'belongs_to :user' association;
- 'rates' table has an integer attribute named 'user_id' (not created with 'references' on migration, but directly with 'integer').

My association is working well, but only after performing a reload on parent object.

Here are the snippets related to this issue: https://bitbucket.org/snippets/cuscos/MbdAK

If I start a 'Padrino Console' and create a user manually, this is the current behavior:

$ user = FactoryGirl.create(:user_with_rates)
$ user.rates.length          # Received '0', but expected '1'
$ user.rates.all.length     # Received '1', OK
$ user.reload!
$ user.rates.length          # Now I'm receiving '1' correctly

It seems that ActiveRecord isn't performing the Lazy Loading for any reason.

Does anyone know why is this happening?

Thanks for all support so far.

For those who it may interest, here is the solution I'm adopting to solve this problem:

In User factory, instead:

after(:create) do |user, evaluator|
  create_list(:rate, evaluator.rates_count, user: user)
end

Do:

after(:create) do |user, evaluator|
  user.rates << create_list(:rate, evaluator.rates_count, user: user)
end

It's not a proper solution, but solved my problem for now.
