RSpec checking database field has a specific string

I'm trying to ensure that when a user is created, the "measurement_units" field has the default string of imperial. When I test by creating a user I get the desired result, but when I test with my spec, I get `got: nil'

Any idea what I'm doing wrong in my spec?

require 'spec_helper'
require 'cancan/matchers'

describe User do
    subject(:user) { User.new(email: '[email protected]', password: '12345678', goal_id: '1', experience_level_id: '1', gender: 'female') }

  it "should be assigned measurement_units of imperial" do
    user.measurement_units.should eq("imperial") 
  end
end

The above test returns:

1) User should be assigned measurement_units of imperial
     Failure/Error: user.measurement_units.should eq("imperial")

       expected: "imperial"
            got: nil

       (compared using ==)
     # ./spec/models/user_spec.rb:20:in `block (2 levels) in <top (required)>'

I know this is probably really basic, but I can't figure it out.

EDIT:

I assign the initial measurement_units in a before create filter on the user model like this:

class User < ActiveRecord::Base

before_create :assign_initial_settings

def assign_initial_settings
  self.measurement_units = "imperial"
end

Your callback is a before_create, but you're not actually calling User.create in your test - hence your callback is not getting run.

If you replace the new with create you should see the behaviour you expect.
