简单记录订阅

您可以使用 Archie Core 自动生成的 GraphQL 订阅操作来订阅正在创建、更新和删除的记录。

在以下示例中，我们有一个名为 students 的表，其中包含诸如 id、firstName、email 等字段和关系。

用于监听正在创建的表记录的订阅。

GraphQL 变更

  }
}

变量

{
  "input": {
    "name": "students_create",
    "description": "Subscription - students table, operation create",
    "active": true,

        "table": "students",
        "operations": ["CREATE"],
        "fields": ["id", "first_name", "email"]
      }
    ]
  }
}

    "data": {
        "system": {
            "createSubscription": {

        }
    }
}

更新订阅

用于监听正在更新的表记录的订阅。

GraphQL 变更

mutation updateSubscription ($input: SubscriptionInput!) {
  system {
    updateSubscription( input: $input ) {
      id
      name
      description
    }
  }
}

变量

      }
    ]
  }
}

用于监听正在删除的表记录的订阅。

GraphQL 变更

mutation deleteSubscription($id: String!) {
  system {

  "id": "id_subscription"
}
