how to select this entity in repository

Question

How can I select this entity in when creating a repository method in typeorm?

I am trying to select password property on Admin entity but this selects Repository not entity

@EntityRepository(Admin)
export class AdminRepository extends Repository<Admin> {

  async comparePasswords(password: string): Promise<boolean> {
    return await compare(password, this.password);
  }

}

When you create a custom repository like this:

admin.repository.ts

@EntityRepository(Admin)
export class AdminRepository extends Repository<Admin> {}

You can use it, for example, in a service or controller (or other class) by injecting it on the constructor like this:

admin.service.ts

@Injectable()
export class AdminService {
    constructor(
        @InjectRepository(AdminRepository)
        private adminRepository: AdminRepository,
    ) {}

    async findAdminByName(name: string): Promise<boolean> {
      return await = this.adminRepository.findOne({name});
    }
}

But if you don't actually need to implement custom methods on repository class (take a look to all standard TypeOrm repository methods), you can achieve the same result without creating the custom repository file admin.repository.ts, and injecting it on the fly directly on a service:

admin.service.ts

@Injectable()
export class AdminService {
    constructor(
        @InjectRepository(Admin)
        private adminRepository: Repository<Admin>,
    ) {}

    async findAdminByName(name: string): Promise<boolean> {
      return await = this.adminRepository.findOne({name});
    }
}
