Umur,

I was able to associate the child objects properly by ensuring they were written to the database when defining the lazy attribute, like so:

user.groups {|groups| [Factory.create(:group)] }

(.create writes the group to the database and ensures it has an ID, which the association then picks up on.)

I simply tried the suggestion making
class User
has_many :posts
class Post
belongs_to :user

In the code above all groups end up with “user_id = nil”. Actually the factory creates the posts and the users. And the result is many unrelated posts and users.

Can we consider it a bug or missing feature of factory girl?
The one to many definition does not work:
user.groups {|groups| [groups.association(:group)]}

I’m sure you couldn’t, and that’s not your fault. It’s not there. I found it on a blog, but since I posted a few days after reading it, I could not remember the source, for what I am sorry.

I try your suggestion but…
All groups end up with “user_id = nil”

If it wasn’t for excellent people like you – who find an answer to an annoying problem like this and then publish it to the world – people like me would spend hours hitting our heads against a brick wall. I salute you!

Just started using Factory Girl and it looks really useful but, unless I’m being thick, I couldn’t find this in the rdoc.
