Pagination without id column in TypeORM

Question

Is there any way of selecting only given columns without id column and using pagination (skip, take) in TypeORM. I'm doing this in NestJS:

article.service.ts:

async getAll(skip: number): Promise<Article[]> {
  return await this.articleRepository.find({
    select: {
      id: false,
      title: true,
      description: true,
      body: false,
      created_at: true,
      updated_at: false,
      author: {
        full_name: true
      }
    },
    relations: {
      author: true
    },
    skip: skip,
    take: 10,
    order: {
      created_at: 'DESC'
    }
  });
}

And in article.controller.ts :

@Get('articles')
async getAll(@Query('page') page: number) {
  if(!page) { page = 1; }
  const skip = (page - 1) * 10;

  const articles = await this.articlesService.getAll(skip);
  return {
    status: true,
    articles: articles,
    page: page,
  }
}

My article.entity.ts :

@Entity()
export class Article {
  
  @PrimaryGeneratedColumn()
  id: number;

  @Column({ length: 100 })
  title: string;

  @Column()
  description: string

  @Column({ type: 'text' })
  body: string;

  @ManyToOne(() => User, (user) => user.articles)
  author: User;

  @CreateDateColumn()
  created_at: string;

  @UpdateDateColumn()
  updated_at: string;
}

When I send a request to this endpoint error happens. I think this is because of pagination(skip, take).

But if I remove skip and take or select the id column it works. Is there any way that I can select other columns without id column and use pagination together

Answer 1

Solved issue temporarily by selecting id columns and removing them before returning

articles.forEach(article => { delete article.id });

Here is the full function from article.service.ts :

async getAll(skip: number): Promise<Article[]> {
  const articles = await this.articleRepository.find({
    select: {
      id: true,
      title: true,
      description: true,
      body: false,
      created_at: true,
      updated_at: false,
      author: {
        full_name: true
      }
    },
    relations: {
      author: true
    },
    skip: skip,
    take: 10,
    order: {
      created_at: 'DESC'
    }
  });
  articles.forEach(article => { delete article.id });
  return articles;
}

NOTE: There should be a better solution though.
