run callback on factorygirl - ruby-on-rails

Question

I have a callback in my user.rb model something like:
class User
include Mongoid::Document
include Mongoid::Timestamps::Created
.
.
.
.
#add a first board for user
after_create :first_board
def first_board
board = self.boards.new(:title => self.username, :category_id => Category.find_or_create_by(slug: "other"))
board.save!
end
end
When a user is created, the app create a new board with above callback.
In my spec/factories/users.rb I have:
FactoryGirl.define do
factory :user do
name 'Test User'
username 'test username'
password 'please'
password_confirmation 'please'
# required if the Devise Confirmable module is used
confirmed_at Time.now
end
end
In my spec/controllers/users_controller_spec.rb I have:
require 'spec_helper'
describe UsersController do
before :each do
request.env['devise.mapping'] = Devise.mappings[:user]
end
include Devise::TestHelpers
before (:each) do
#user = FactoryGirl.create(:user)
sign_in #user
end
describe "GET 'show'" do
it "should be successful" do
get :show, :id => #user.id
response.should be_success
end
it "should find the right user" do
get :show, :id => #user.slug
assigns(:user).should == #user
end
end
end
How can I run my callback with factorygirl?
I get 2 errors:
Failures:
1) UsersController GET 'show' should be successful
Failure/Error: #user = FactoryGirl.create(:user)
Errno::ECONNREFUSED:

# (eval):2:in `post'

Answer 1

The find_or_create_by method can't be called like that, afaik. It uses method_missing and expects an activerecord attribute tacked on the end. Try:
Category.find_or_create_by_slug("other")
