fg_find_or_create.rb

module FactoryGirl::Syntax::Methods
  def find_or_create(name, attributes = {}, &block)
    factory = FactoryGirl.factory_by_name(name)
    clazz   = factory.build_class

    factory_attributes = FactoryGirl.attributes_for(name)
    attributes = factory_attributes.merge(attributes)

    clazz.find_or_create_by(attributes, &block)
  end
end

Thanks for this -

One thing I noticed, is that line #9 isn't actually using FactoryGirl to create the object.

I've made some adjustments here: https://gist.github.com/thewatts/dcc91ef40b144aff42ae
