打字稿和graphql-codegen之间的枚举不匹配

[英]Enum mismatch between typescript and graphql-codegen

我目前正试图解决以下问题,并没有走得太远。 目前,我正在运行 Apollo-Server 作为我的 graphQL 服务器,prisma2 配置了 postgres 数据库,并且正在利用 graphql-codegen 从我的模式生成类型。 目前,我正在尝试更新一个具有多对多关系的模型,并且会抛出非常奇怪的打字稿错误。 我很确定我做的更新不正确,但我看到的错误没有帮助。

以下是相关的代码片段:

棱镜模式

model Permission {
  id       Int             @id @default(autoincrement())
  verb     PermissionVerb
  resource PermissionModel
  own      Boolean         @default(true)
  roles    Role[]
}
    
model Role {
  id          Int          @id @default(autoincrement())
  name        String
  permissions Permission[]
}

enum PermissionModel {
  USER
  ORDER
  CUSTOMER
  PERMISSION
  ROLE
}

enum PermissionVerb {
  CREATE
  READ
  UPDATE
  DELETE
}

权限.gql

extend type Mutation {
  updatePermission(input: UpdatePermissionInput): PermissionResult!
}

union PermissionResult = Permission | PermRoleNotFoundError

type Permission {
  id: Int!
  own: Boolean
  resource: PermissionModel!
  verb: PermissionVerb!
  roles: [Role]
}

type Role {
  id: Int!
  name: String!
  permissions: [Permission]
}

type PermRoleNotFoundError {
  message: String!
}

enum PermissionModel {
  USER
  ORDER
  CUSTOMER
  PERMISSION
  ROLE
}

enum PermissionVerb {
  CREATE
  READ
  UPDATE
  DELETE
}

最后是解析器中的违规代码:

更新权限.ts

export const updatePermission: Resolver<
  ResolversTypes['UpdatePermissionInput'],
  {},
  Context,
  RequireFields<MutationUpdatePermissionArgs, never>
> = async (_parent, args, context, _info) => {
  const { id, verb, resource, own } = args.input

  const oldPermission = await context.prisma.permission.findFirst({
    where: { id },
    include: { roles: true }
  })

  const newPermission = await context.prisma.permission.update({
    where: { id },
    data: {
      id: oldPermission.id,
      verb: verb ? verb : oldPermission.verb,
      resource: resource ? resource : oldPermission.resource,
      own: own ? own : oldPermission.own,
    },
  })

  return newPermission
}

我收到以下打字稿警告:

Type '(_parent: {}, args: RequireFields<MutationUpdatePermissionArgs, never>, context: Context, _info: GraphQLResolveInfo) => Promise<...>' is not assignable to type 'Resolver<UpdatePermissionInput, {}, Context, RequireFields<MutationUpdatePermissionArgs, never>>'.
Type '(_parent: {}, args: RequireFields<MutationUpdatePermissionArgs, never>, context: Context, _info: GraphQLResolveInfo) => Promise<...>' is not assignable to type 'ResolverFn<UpdatePermissionInput, {}, Context, RequireFields<MutationUpdatePermissionArgs, never>>'.
Type 'Promise<Permission>' is not assignable to type 'UpdatePermissionInput | Promise<UpdatePermissionInput>'.
Type 'Promise<Permission>' is not assignable to type 'Promise<UpdatePermissionInput>'.
Type 'Permission' is not assignable to type 'UpdatePermissionInput'.
Types of property 'verb' are incompatible.
Type 'import(\"/Users/jrichardson/Documents/Projects/wsw/node_modules/.prisma/client/index\").PermissionVerb' is not assignable to type 'import(\"/Users/jrichardson/Documents/Projects/wsw/backend/src/generated/graphql\").PermissionVerb'.
Type '\"CREATE\"' is not assignable to type 'PermissionVerb'.

我不明白为什么它认为 PermissionVerb 不可分配 - 从我从 .prisma/client/index 和生成的/graphql 中可以看到,两个枚举是相同的。 不确定我在这里缺少什么。

任何帮助将不胜感激! 谢谢

棱镜枚举不可分配给graphql枚举..这就是问题

按graphql的类型转换返回..

import { Permission  as PermissionQL  } from "../../generated/graphql";
...
return newPermission as PermissionQL;

这样我就解决了同样的问题。

您还可以通过在codegen.yml设置来告诉 graphql-codegen 将枚举创建为 const(字符串联合):

config:
  enumsAsConst: true
