Using FactoryGirl callbacks

callbacks.rb

# let's say I want to execute a callback before making a FactoryGirl fixture using #create
factory :thing do
  before(:create) do |foo|
    foo.bar = create :baz
  end
end

# but then I also want to call the same block after making a FactoryGirl fixture using #build
factory :thing do
  before(:create) do |foo|
    foo.bar = create :baz
  end
  
  after(:build) do |foo|
    foo.bar = create :baz
  end
end

# that's not DRY, but using FactoryGirl#callback is:

factory :thing do
  callback(:before_create, :after_build) do |foo|
    foo.bar = create :baz
  end
end
