factory_girl_elixir

Hi there,

perhaps it might be my fault, but it I wasn't able to reference a factory from another definition. This is a common use case, for example when you want create a record on the fly to associate to another factory.

to quickly test this, I've modified your test/factory_girl_elixir_test.exs this way:

[...]
    factory :user do
      field :name, "joe"
      field :password, "secret"
      field :email, &("foo#{&1}@example.com")

      # getting a value through another factory
      field :asset_name, fn(_) ->
        assets = Factory.attributes_for(:assets) |> Factory.parametrize
        assets.name
      end
    end

    factory :assets do
      field :name, "bob"
    end
[...]

when I run mix test I get this:

=ERROR REPORT==== 7-Sep-2015::23:00:32 ===

     {proc_lib,init_p_do_apply,3,[{file,"proc_lib.erl"},{line,239}]}]}

of course, the tests are broken.

Any hint or workaround for this? :-P
