Question

Nest新一米,与 Nest合作使用这些类型 Orm “@nestjs/typeorm”:“^9.0.1”,“eorm”:“^0.3.11”, I m 带这种错误“TypeError:Cannot读物我确实不理解为什么没有定义。页: 1 一种是被解释的,我可以使用发现By One。但每次我都尝试利用邮政员进行测试。我发现这一错误。所附的是以下终点站的错误。在如何解决这一问题方面,将受到高度赞赏。

我试图将类型改为“^0.2.32”的低版本,该版本确定了错误,但在操作时又出现了另一个错误。但我想与最新版本合作,一是在线查询,看看一看能否找到任何帮助,但与我的问题无关。

这里是我的法典。此外,我注意到,实体保存人在作出解释时被删除。

简言之,在您的存放处,你是失踪的实体管理人,你需要在海关储存库内提供一个叫做<代码>super(<>。

There are several ways how you can approach, and those can be found in typeorm docs and nestjs docs:

https://typeorm.io/custom-repository
https://docs.nestjs.com/techniques/database#repository-pattern and https://docs.nestjs.com/techniques/database#repository-pattern
sticking with custom repositories, and that can be searched and found on internet

我在结束发言时只是从打字器(0.2.45到0.3.11和@nestjs/typeorm>_9.0.1。

Our code base consists of 70+ custom repositories, which are used on many places: services, tests, seeds, fixes (something like custom migrations)... For that reason, for now we stick to the custom class repositories (as before), although I am not sure if that is way to go. At least app seems to work, tests are passing. But maybe we will update things in iterations, once we have more feedback in community - which are preferred ways and which are not (and why).

App.module.ts

TypeOrmModule.forRootAsync({
      useFactory: async (appConfig: ConfigService) => ({
        type:  postgres ,
        ...config.database,
        entities: [`${__dirname}/modules/**/*.entity{.ts,.js}`],
      }),
      dataSourceFactory: async (dataSourceOptions) => {
        const dataSource = await new DataSource(dataSourceOptions).initialize();
        return dataSource;
      },
      inject: [ConfigService],
    }),

repository.ts

@Injectable()
export class UserRepository extends Repository<User> {
  constructor(private readonly emanager: EntityManager) {
    super(User, emanager);
  }
  // down we have custom logic-methods...

user.service.ts

export class UserService {
  constructor(
    private readonly dataSource: DataSource,
    private readonly userRepo: UserRepository,

user.module.ts

@Module({
  imports: [
    TypeOrmModule.forFeature([User]),
    ...
  ],
  controllers: [UserController],
  providers: [UserService, UserRepository],
  exports: [UserService],
})
export class UserModule {}

For the end, very important, transactions pseudocode inside user.service.ts:

await this.dataSource.transaction(async (tManager) => {
   const userRepo = new UserRepository(tManager);
   ...

我赞同这一看法,主要是从社区得到(坏或好)反馈。

您还可以更新其书面文件,以包括以下内容(如果它像我国一样只引述了遗嘱延期)。
