GraphQL错误: Unknown argument 'deleted' on field 'removeFromPostsOnComments'

Question

因此，我从帖子到评论之间存在一对多关系:

type Comments {
  createdAt: DateTime!
  deleted: Boolean
  id: ID!
  posts: Posts @relation(name: "PostsOnComments")
  text: String!
  updatedAt: DateTime!
  user: String!
}

type Posts {
  caption: String!
  comments: [Comments!]! @relation(name: "PostsOnComments")
  createdAt: DateTime!
  displaysrc: String!
  id: ID!
  likes: Int
  updatedAt: DateTime!
}

并且希望运行一个突变，除了删除帖子和评论之间的连接之外，还尝试将评论中的“已删除”字段更新为 true:

mutation removeComment ($id: ID!, $cid: ID!, $stateB: Boolean) {
  removeFromPostsOnComments (postsPostsId: $id, commentsCommentsId: $cid, deleted: $stateB){
    postsPosts {
      __typename
      id
      comments {
        __typename
        id
        text
        user
        deleted
        posts {
          __typename
          id
        }
      }
    }
  }
}
  
Query Variables

{
  "id": "cj0qkl04vep8k0177tky596og",
  "cid": "cj1de905k8ya201934l84c3id"
}

但是当我运行突变时，我收到以下错误消息:

GraphQL error: Unknown argument 'deleted' on field 'removeFromPostsOnComments' of type 'Mutation'. (line 2, column 74):
  removeFromPostsOnComments(postsPostsId: $id, commentsCommentsId: $cid, deleted: $stateB) {

正如向我解释的那样 here ，仅删除帖子和评论之间的链接，而不是实际的“评论”记录本身。所以我的想法是，既然记录没有被删除，为什么我不能更新“已删除”字段？

我希望这样做，以便它触发订阅，该订阅正在监视 updated字段“已删除”。

生成的变异输出如下:

  "data": null,
  "errors": [
    {
      "message": "Unknown argument 'deleted' on field 'removeFromPostsOnComments' of type 'Mutation'. (line 2, column 77):\n    removeFromPostsOnComments (postsPostsId: $id, commentsCommentsId: $cid, deleted: $stateB){\n                                                                            ^",
      "locations": [
        {
          "line": 2,
          "column": 77
        }
      ]
    }
  ]
}

如图所示，“已删除”肯定包含在我的 GraphCool 架构的“评论”中:

我重现了您的问题。首先，您收到错误消息，因为 deleted 不是 removeFromPostsOnComments 突变的参数的一部分，您还在文档中看到:

如果您想更新 Comments 类型上的 deleted 字段，则必须使用 updateComments-mutation:

mutation {
  updateComments(id: "cj1de905k8ya201934l84c3id", deleted: true) {
    id
  }
}
