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:
父类
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
工厂
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
更新
但我可以成功地做到以下几点,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
可能会尝试保存OrderLine
,因为父母尚未保存会导致错误 - 但我不知道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。
答案 0 :(得分:7)
您需要将OrderLine工厂放入订单记录中,如此
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
