[SOLUCIONADO] Relaciones entre modelos no me dejan crear uno con FactoryGirl.build

[kyxer]

Código:

class User < ActiveRecord::Base
  has_many :events
  has_many :participants
  has_many :events, through: :participants
end

class Event < ActiveRecord::Base
  belongs_to :user
  belongs_to :event_status
  has_many :participants
  has_many :user, through: :participants
end

class Participant < ActiveRecord::Base
  belongs_to :user
  belongs_to :event
end

FactoryGirl.define do
    factory :event do
    	user
    	event_status
        name { FFaker::Name.name }
        description { FFaker::Lorem.phrase }
        avatar { FFaker::Avatar.image }
        latitude { FFaker::Geolocation.lat }
        longitude { FFaker::Geolocation.lng }
    end
end

FactoryGirl.define do
  factory :user do
    first_name { FFaker::Name.first_name }
    last_name { FFaker::Name.last_name }
    phone_number { FFaker::PhoneNumber.phone_number }
    email { FFaker::Internet.email }
    handle { FFaker::Name.name }
    password "12345678"
    imei "1234567890"
    gender "M"
  end
end

FactoryGirl.define do
  factory :event_status do
  	name { FFaker::Name.first_name }
  	description { FFaker::Lorem.phrase }
  end
end

Cuando trato de crear un modelo para mi prueba en la consola de rails

Código:

event = FactoryGirl.build(:event)

Me sale el siguiente error

Código:
