Question

大家好，

我使用Nodejs和Koajs用Typeorm制作了一个API。

当我调用我的API端点之一时，我遇到了一个小问题。端点应该创建新的内容。而是在尝试保存时抛出错误。

错误：

{
    "success": false,
    "error": {
        "message": "ER_WRONG_VALUE_COUNT_ON_ROW: Column count doesn't match value count at row 1",
        "code": "ER_WRONG_VALUE_COUNT_ON_ROW",
        "errno": 1136,
        "sqlMessage": "Column count doesn't match value count at row 1",
        "sqlState": "21S01",
        "index": 0,
        "sql": "INSERT INTO `content`(`id`, `title`, `content`) VALUES ('9c29e73c-9bd0-4cf3-bea4-ad38f5082790', `title` = 'Test', `content` = 'Contenthaha', DEFAULT)",
        "name": "QueryFailedError",
        "query": "INSERT INTO `content`(`id`, `title`, `content`) VALUES (?, ?, DEFAULT)",
        "parameters": [
            "9c29e73c-9bd0-4cf3-bea4-ad38f5082790",
            {
                "title": "Test",
                "content": "Contenthaha"
            }
        ]
    }
}

端点：

@Post('/content')
  async postOne(@Body() title: string, content: string) {
    const { repository } = this;

    try {
      const newContent = repository.create({
        title,
        content
      });

      await repository.save(newContent);
    } catch (exception) {
      return { 'success': false, 'error': exception };
    }

    return { 'success': true, 'message': 'Content was successfully created' };
  }

当我在引发错误之前在控制器中返回newContent时，我得到了在Postman中返回的这个奇怪的JSON：

{
    "title": {
        "title": "Test",
        "content": "Contenthaha"
    }
}

我的模型：

import {
  Entity,
  PrimaryGeneratedColumn,
  Column,
} from 'typeorm';

@Entity()
export class Content {
  @PrimaryGeneratedColumn('uuid')
  id!: number;

  @Column()
  title!: string;

  @Column({ type: 'longtext' })
  content!: string;
}

希望我能帮助别人，因为我不在这里。

谢谢！

查询后Typeorm打印随机DEFAULT值
