【中文标题】prisma 部署后，prisma 没有应用更改

【英文标题】：prisma isn't applying changes after prisma deploy

【问题描述】：

我已经更新了我的数据模型中的一些类型，并且在运行$prisma deploy 时它显示已经进行了更改。然而，playground 并没有反映这一点，在再次运行 $prisma deploy 时，它会重新更新相同的更改。

我一次又一次地收到这条消息，让我相信我的更新没有保存。

datamodel.prisma

type User 
  id: ID! @id
  name: String!
  email: String! @unique
  posts: [Post!]!
  comments: [Comment!]!



type Post 
  id: ID! @id
  title: String! 
  body: String!
  published: Boolean! 
  author: User!
  comments: [Comment!]!


type Comment 
    id: ID! @id
    text: String!
    author: User!
    post: Post!

棱镜.yml

endpoint: http://localhost:4466

Your Prisma endpoint is live:

  HTTP:  http://localhost:4466
  WS:    ws://localhost:4466

You can view & edit your data here:

  Prisma Admin: http://localhost:4466/_admin

【参考方案1】：

查看 pgAdmin 中的迁移表：

SELECT * FROM management."Migration"
ORDER BY "projectId" ASC, revision DESC

这可能是由于 postgre 引发的错误未显示在控制台的 prisma deploy 输出中。

对我来说，这是因为我将 User.email 设置为 @unique，但已经有多个用户使用相同的电子邮件，奇怪的是它没有被捕获，之后 postgre 不再接受任何迁移。

我在这里报告了这个错误：https://github.com/prisma/prisma/issues/2675

【参考方案2】：

同样的问题已经有一段时间了。不知道是什么问题，但我设法绕过它

将prisma.yml中的棱镜端点从http://localhost:4466更改为http://locolhost:4466/anylabel/default 然后运行prisma1 deploy

这会将您的应用部署到数据库上的新服务上。

然后您可以在http://locolhost:4466/anylabel/default 上查看新模型的更改

（希望对您有所帮助，但我想您可能已经找到了解决方案）

【参考方案3】：

使用应该可以工作的prisma1 deploy
