Question

我正在尝试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
      at SequelizeAdapter.get (node_modules/src/adapters/DefaultAdapter.js:13:18)
      at AssocAttrs.get [as getAttribute] (node_modules/src/generators/Generator.js:15:46)
      at AssocAttrs.getAttribute (node_modules/src/generators/AssocAttrs.js:7:23)
      at tryCatch (node_modules/babel-runtime/node_modules/regenerator-runtime/runtime.js:62:40)

      at /Users/daniel.pan/Documents/projects/BudgetApp/node_modules/babel-runtime/helpers/asyncToGenerator.js:28:13

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')
})

我正在尝试将“费用”与“类别”和“用户”相关联。我可以只使用“ assoc”，它可以工作，但这是我不想要的持久化模型。文档说要使用“ assocAttrs”来嵌入无法持久保存的模型，但是我总是会收到类型错误。我不知道该如何进行。

这太晚了，但是请从以下位置更改categoryId的代码行：

categoryId: factory.assocAttrs('Category', 'id'),

收件人：

categoryId: factory.assocAttrs('Category'),

在调用时应导致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。那就是Expense.category = {propA: 'whatever you've defined', probB: 'etc...', categoryId: '123-213-123'}

为确保在上述JSON对象中将Expense.categoryId属性仅设置为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)
