Javascript 具有突变图COLL/graphql的重复项

我正在使用

graphtool

/

graphql

，希望将

Player

添加到

团队中。我的模式如下所示：

type Team @model {
  id: ID! @isUnique
  name: String
  players: [Player!]! @relation(name: "TeamPlayers")
  fixtures: [Fixture!]! @relation(name: "TeamFixtures")
  results: [Result!]! @relation(name: "TeamResults")
}

type Player @model {
    id: ID! @isUnique
    name: String!
    gamesPlayed: Int!
    goalsScored: Int!
    yellowCards: Int!
    redCards: Int!
    photo: String!
    team: Team! @relation(name: "TeamPlayers")
}

我正在进行以下突变：

mutation {
      createPlayer(
      name: "Peter Flanagan",
      gamesPlayed: 1,
      yellowCards: 0,
      redCards: 1,
      goalsScored: 4,
      photo: "http://cdn2-www.craveonline.com/assets/uploads/2017/02/bret1.png",
      team: {
        name: "Man United"
      }
    ) {
        id
      }
}

这和预期的一样有效，但是如果我做了另一个突变，比如下面的一个，第二个团队，也被称为
manunited
，有一个新的
id

mutation {
      createPlayer(
      name: "Eric Cantona",
      gamesPlayed: 1,
      yellowCards: 0,
      redCards: 1,
      goalsScored: 4,
      photo: "http://cdn2-www.craveonline.com/assets/uploads/2017/02/bret1.png",
      team: {
        name: "Man United"
      }
    ) {
        id
      }
}

有谁能建议我如何避免这个问题并将两个
玩家添加到同一个
团队
。如果你想把球员和球队联系起来。首先创建
team
并获取
teamId
。使用
teamId
，您可以创建与团队连接的变体，如下所示：

mutation {
  createPlayer(
  name: "Peter Flanagan",
  gamesPlayed: 1,
  yellowCards: 0,
  redCards: 1,
  goalsScored: 4,
  photo: "http://cdn2-www.craveonline.com/assets/uploads/2017/02/bret1.png",
  teamId: "TEAM_ID"
) {
    id
  }
}

这样，您总是可以通过创建新的
玩家来创建新的
团队
。如果你想把球员和球队联系起来。首先创建
team
并获取
teamId
。使用
teamId
，您可以创建与团队连接的变体，如下所示：

mutation {
  createPlayer(
  name: "Peter Flanagan",
  gamesPlayed: 1,
  yellowCards: 0,
  redCards: 1,
  goalsScored: 4,
  photo: "http://cdn2-www.craveonline.com/assets/uploads/2017/02/bret1.png",
  teamId: "TEAM_ID"
) {
    id
  }
}
