@connection 必须位于 @model 对象类型字段上

Question

我有一个像这样的用于 AWS 的小型 graphQL 结构，但是当我尝试推送它时抛出一个错误提示

✖ An error occurred when pushing the resources to the cloud

@connection must be on an @model object type field.

请帮助理解我哪里出错了。

是否有任何 VS 代码扩展来调试这个？

type Store {
  id: ID!
  products: [Product] @connection(name: "StoreProducts")
}

type Product @model @searchable {
  id: ID!
  name: String!
  description: String!
  price: Float!
  isOnCourse: Boolean!
  isOnOutlet: Boolean!
  store: Store @connection(name: "StoreProducts", sortField: "crearedAt")
  file: S3Object!
}

type S3Object {
  bucket: String!
  region: String!
  key: String!
}

type User
  @model(
    queries: { get: "getUser" }
    mutations: { create: "registredUser", update: "updateUser" }
    subscriptions: null
  ) {
  id: ID!
  username: String!
  email: String!
  phoneNumber: String!
  registred: Boolean
  orders: [Order] @connection(name: "UserOrders", sortField: "createdAt")
}

type Order
  @model(
    queries: null
    mutations: { create: "createOrder" }
    subscriptions: null
  ) {
  id: ID!
  product: Product @connection
  user: User @connection(name: "UserOrders")
  orderLocation: OrderLocation
  crearedAt: String
}

type OrderLocation {
  tableNumber: String
  qrData: String
  holeNumber: String
}

当您在产品类型上创建关系时

store: Store @connection(name: "StoreProducts", sortField: "crearedAt")

您必须告诉服务器如何查找这些项目。通过哪个字段名称。这就是为什么您收到此错误“@connection 必须位于 @model 对象类型字段上。”

解决方案是添加 fields。在类型Product上如果你想带Store Products，你需要添加“id”字段。

store: Store @connection(name: "StoreProducts", fields:["id"] sortField: "crearedAt")

在所有其他类型中，如果你想有关系，你必须定义一个方便的字段来查询数据。
