Setting nil values in Machinist blueprints
Take care when trying to set attributes to nil
in a blueprint.
Given the following master blueprint:
Story.blueprint do
title
author { User.make }
editor { User.make }
end
This approach will not overwrite/remove the editor
defined in the master blueprint:
Story.blueprint(:draft) do
editor nil
end
...whereas this one will (note the lambda):
Story.blueprint(:draft) do
editor { nil }
end

Several Rails migration methods accept index: true

instead.
