Factory Girl - Why are Records being continually created? - ruby-on-rails

Question

I'm new to factory girl. What I'm trying to do is create 2 users, which belong to a group, joined by the permission model. Here's what I have. When I run this one rspec, it creates more than 2 users, 4+. Why? thanks
factories.rb:
require 'factory_girl'
Factory.define :user do |f|
f.sequence(:fname) { |n| "fname#{n}" }
f.sequence(:lname) { |n| "lname#{n}" }
f.sequence(:email) { |n| "email#{n}#google.com" }
f.password "password"
f.password_confirmation { |u| u.password }
f.invitation_code "xxxxxxxx"
end
Factory.define :group do |f|
f.association :user
f.sequence(:name) { |n| "myGroup#{n}" }
f.sequence(:private_email) { |n| "myGroup#{n}" }
end
Factory.define :permission do |f|
f.role_id 1
f.user {|i| i.association(:user)}
f.group {|i| i.association(:group)}
f.creator_id {|i| i.association(:user).id}
end
incoming_mails_controller_spec.rb:
describe IncomingMailsController do
include Devise::TestHelpers
before do
#user = Factory.create(:user, :permissions => [Factory.create(:permission)])
#user2 = Factory.create(:user, :permissions => [Factory.create(:permission)])
#group = Factory(:group)
end
it "should create a new IncomingMail record in the db" do
....
end
....

Answer 1

This is because Factory.create(:user...) creates 1 one user (you have two of these, so thats two users right there). And creating two new Factory.create(:permissions) also creates a user by the rules you set up in your define(your associations), thus equaling 4.
If you wanted to to only create two users here, you could do
#user = Factory.create(:user)
#user1 = Factory.create(:user)
#perm1 = Factory.create(:permission, :user => #user)
#perm2 = Factory.create(:permission, :user => #user1)
