Prisma datamodel.prisma 在模型上给出了几个错误

Question

我正在学习使用 GraphQl 和 prisma，我正在学习本教程 --> https://www.howtographql.com/graphql-js/4-adding-a-database/

我遵循了它，但是将 Link 更改为具有名称字段和成本的服务（现在这是一个字符串），我制作了一个 datamodel.prisma 文件，看起来像这个

type Service {
    id: ID! @id
    createdAt: DataTime! @createdAt
    updatedAt: DataTime! @updatedAt
    name: String!
    cost: String!
}

但它给了我这个错误，我不明白它应该是正确的语法吗？:

Errors:

  Service
    × The field `createdAt` has the type `DataTime!` but there's no type or enum declaration with that name.
    × The field `updatedAt` has the type `DataTime!` but there's no type or enum declaration with that name.
    × The relation field `createdAt` must specify a `@relation` directive: `@relation(name: "MyRelation")`
    × The relation field `updatedAt` must specify a `@relation` directive: `@relation(name: "MyRelation")`
    × Fields that are marked as `@createdAt` must be of type `DateTime!` or `DateTime`.    
    × Fields that are marked as @updatedAt must be of type `DateTime!` or `DateTime`.

我不确定为什么我的数据模型会出现这些错误，谁能帮我解决这个问题

Answer 1

您打错了 -- 是 DateTime，而不是 DataTime。
