title: FactoryGirl gives wrong value on enum status field
body: <p>I am trying to build a FactoryGirl factory for the Client.rb model:</p>
  
  <p>Client.rb</p>
  
  <pre><code>  enum status: [ :unregistered, :registered ]
  
   has_many :quotation_requests
  
    #Validations
  
    validates :first_name, 
              presence: true,
              length: {minimum: 2}
  
    validates :last_name, 
              presence: true,
              length: {minimum: 2}
  
    validates :email, email: true
  
    validates :status, presence: true
  </code></pre>
  
  <p>Factory:</p>
  
  <pre><code>FactoryGirl.define do
    factory :client do
      first_name "Peter"
      last_name "Johnson"
      sequence(:email) { |n| "peterjohnson#{n}@example.com" }
      password "somepassword"
      status "unregistered"
    end
  end
  </code></pre>
  
  <p>client_spec.rb</p>
  
  <pre><code>    require 'rails_helper'
  
      RSpec.describe Client, type: :model do
  
          describe 'factory' do
  
            it "has a valid factory" do
              expect(FactoryGirl.build(:client).to be_valid
            end
  
          end
  end
  </code></pre>
  
  <p>I get the following errorL</p>
  
  <pre><code>  1) Client factory has a valid factory
       Failure/Error: expect(FactoryGirl.build(:client, status: 'unregistered')).to be_valid
         expected #&lt;Client id: nil, email: "peterjohnson1@example.com", encrypted_password: "$2a$04$urndfdXNfKVqYB5t3kERZ.c.DUitIVXEZ6f19FNYZ2C...", first_name: "Peter", last_name: "Johnson", status: "0", reset_password_token: nil, reset_password_sent_at: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: nil, updated_at: nil&gt; to be valid, but got errors: Status can't be blank
  </code></pre>
  
  <p>The error is that Status can't be blank. </p>
  
  <p>I don't understand how this is possible as the factory is clearly assigning a value to the status attribute.</p>
  
  <p>How can I get this factory to build a valid client object?</p>
