我试图将工厂模型与非持久模型相关联,但出现错误:
TypeError: model.get is not a function

这是我拥有的工厂:
import models from '../../models'
import faker from 'faker/locale/en'
export default factory.define('Expense', models.Expense, {
id: factory.seq('id'),
value: faker.finance.amount(0, 200),
note: faker.lorem.sentence(),
categoryId: factory.assocAttrs('Category', 'id'),
userId: factory.assocAttrs('User', 'id')
})
我试图将“费用”与“类别”和“用户”联系起来。
我可以只使用“assoc”并且它可以工作,但这适用于我不想要的持久模型。文档说要使用“assocAttrs”来嵌入未持久化的模型,但是我总是遇到类型错误。我不知道如何继续。
最佳答案
这已经很晚了,但是将 categoryId
的代码行更改如下:
categoryId: factory.assocAttrs('Category', 'id'),
至:
categoryId: factory.assocAttrs('Category'),
调用时应该会产生 JSON 输出:
factory.build('Expense').then(x => console.log(x)).
您会注意到您的
categoryId
属性将包含一个 JSON 对象,该对象将包含初始化为您定义它们的属性。那是 Expense.category = {propA: 'whatever you've defined', probB: 'etc...', categoryId: '123-213-123'}
为确保
Expense.categoryId
属性仅设置为上述 JSON 对象中的 categoryId
,您需要将我上面提到的代码行更改为:categoryId: factory.assocAttrs('Category')().then(y => y.categoryId)
