我是 AWS Amplify 和 GraphQL 的新手。也刚刚开始构建 React Native App - 这很有趣！

我有一个名为 TimePeriods 架构的表，它看起来像这样

type TimePeriod @model {
  id: ID!
  name: String!
  startYear: String!
  endYear: String!,
  artworks: [ArtWorkTimePeriod] @connection (name: "TimePeriodArtWorks") #Many to Many Relationship
  artists: [ArtistTimePeriod] @connection (name: "TimePeriodArtists") #Many to Many Relationship
}

在由 amplify 生成的查询文件中，我有一个名为 listTimePeriods 的函数。

export const listTimePeriods = /* GraphQL */ `
  query ListTimePeriods(
    $filter: ModelTimePeriodFilterInput
    $limit: Int
    $nextToken: String
  ) {
    listTimePeriods(filter: $filter, limit: $limit, nextToken: $nextToken) {
      items {
        id
        name
        startYear …
