我有一个FactoryGirl工厂,它创建一个Order但是before(：create)回调不会创建关联的工厂对象：
家长班
class Order < ActiveRecord::Base attr_accessible :tax,:total has_many :order_lines validates :user,presence: true validates :order_lines,presence: true end
儿童班
class OrderLine < ActiveRecord::Base attr_accessible :order,:product,:qty belongs_to :order belongs_to :product ... ... validates :order,presence: true end
厂
Factory :order do
...
ignore do
number_or_order_lines 1
end
before(:create) do |order,evaluator|
FactoryGirl.create_list :order_line,evaluator.number_or_order_lines,order: order
end
end
Factory :order_line do
association :user
association :order
...
end
问题
在我的rspec测试中,如果我创建一个订单对象：
describe Order do
before {@order = FactoryGirl.create(:order) } => #throws error (see below)
end
错误
的ActiveRecord :: RecordInvalid
验证失败订单行不能为空
UPDATE
然而,我可以成功地执行以下操作,但显然只能完成创建一个：
after(:build) do |order,evaluator| order.order_lines << FactoryGirl.build(:order_line,order: order) end
假设 – 我可以看到create_list可能试图保存OrderLine的位置,这会导致错误,因为父节点尚未保存 – 但我不知道它是否仍然返回一个处于无效状态的OrderLine对象因此,订单对象上的order_lines集合仍然不应为空.
解决方法
您需要将OrderLine工厂放入订单记录中
Factory :order do
...
ignore do
number_or_order_lines 1
end
before(:create) do |order,evaluator|
order.order_lines << (FactoryGirl.create :order_line,order: order)
end
end
