我面临着与问题相同的问题这里。这个帖子已经过时了。我想知道如何做同样的事情。我的工厂是：
FactoryGirl.define do
factory :user do
sequence(:email) {|n| "email#{n}@factory.com" }
password "foobar"
password_confirmation { |u| u.password }
profile
end
end
但是FactoryGirl.create（：user）失败，因为配置文件模型中的验证错误，用户为空。
我要做的是在创建之后使用。这确保了它只在创建用户后创建配置文件。
factory :user do
sequence(:email) {|n| "email#{n}@factory.com" }
password "foobar"
password_confirmation { |u| u.password }
after_create do |user|
FactoryGirl.create(:profile, :user => user)
end
end
之后可以调用工厂（：user）。
