如何更新部分amplify graphql模型？

Question

我是Aws Amplify和GraphQL的新手，我正在尝试找到处理以下问题的最佳方法：

我希望能够在前台编辑我的常见问题。前端从后端获取数据，我在前台编辑一个字段并保存，它应该存储在后端

我已经创建了一个简单的amplify graphql模式：

type FAQ @model(timestamps: null) {
  id: ID!
  sectionTitle: String
  questionAndAnswer: [QuestionAndAnswer!]!
}

type QuestionAndAnswer {
  id: ID!
  question: String
  answer: String
}

然后我填充了它，使其包含以下数据：

{
  "data": {
    "listFAQS": {
      "items": [
        {
          "sectionTitle": "Title2",
          "id": "22735682-2bab-4695-b93e-1e50642d4654",
          "questionAndAnswer": [
            {
              "answer": "answer4",
              "id": "4",
              "question": "question4"
            },
            {
              "answer": "answer5",
              "id": "5",
              "question": "question5"
            },
            {
              "answer": "answer6",
              "id": "6",
              "question": "question6"
            }
          ]
        },
        {
          "sectionTitle": "Title1",
          "id": "21be8234-69f2-47fe-b942-d3e655197c70",
          "questionAndAnswer": [
            {
              "answer": "answer1",
              "id": "1",
              "question": "question1"
            },
            {
              "answer": "answer2",
              "id": "2",
              "question": "question2"
            },
            {
              "answer": "answer3",
              "id": "3",
              "question": "question3"
            }
          ]
        }
      ]
    }
  }
}

有没有一种简单的方法，我可以只改变例如问题"question4“，而不必发送整个常见问题”行“？

当我尝试它的时候，似乎整个数组都被重置了，只保存了新的数据。常见问题解答和QuestionAndAnswer是否都应该是@模型，我用@connection将它们连接起来，并根据需要分别更新它们？

Answer 1

下面似乎是一种简单的方法，因为如果需要，您可以通过使用带有GraphQL突变的唯一ID来仅更新"question4“。

type FAQ @model(timestamps: null) {
  id: ID!
  sectionTitle: String
  questionAndAnswer: [QuestionAndAnswer!]!
}

type QuestionAndAnswer @model {
  id: ID!
  question: Question
  answer: Answer
}

type Question @model {
  id: ID!
  question: String
}

type Answer @model {
  id: ID!
  answer: String
}

我没有包括@connections (它们应该在QuestionAndAnswer模型中)，但是“FAQ和QuestionAndAnswer应该都是@模型吗?我用@connection连接它们，并根据需要分别更新它们？”
