Faker is producing duplicate data when used in factory_girl

Question

I\'m trying to populate some fake data into a factory using the Faker gem:

Factory.define :user do |user|
  user.first_name Faker::Name::first_name
  user.la         


        

Answer 1

A (less efficient) alternative to using sequences when you have a uniqueness validation on an attribute is to check whether a proposed value already exists and keep trying new ones until it's unique:

FactoryGirl.define do
  factory :company do
    name do
      loop do
        possible_name = Faker::Company.name
        break possible_name unless Company.exists?(name: possible_name)
      end
    end
  end
end
