英文:
NestJS changing param names received in post request
问题
我希望一个端点能够接收JSON请求中的 firstName 并将其保存为我的数据库中的 first_name。
我创建了一个DTO来概述我希望端点接收的参数，如下所示：
@IsNotEmpty()
@Expose({ name: 'firstName' })
first_name: string;
甚至在vscode中也能识别到属性名称应该是 first_name。
然而，当我使用console.log时，我收到了这个（而不是 first_name）：
{
email: 'test@test.com',
password: 'test',
firstName: 'first',
lastName: 'last'
}
（我的数据库实体也将该字段设置为 first_name，并且出现了错误）
英文:
My goal is for an endpoint to receive firstName in the JSON request and save first_name in my DB.
I created a dto outlining the params I want to receive for the endpoint like so:
@IsNotEmpty()
@Expose({ name: 'firstName' })
first_name: string;
vscode even picks up that the prop name should be first_name.
However when I console.log it I receive this: (firstName instead of first_name)
{
email: 'test@test.com',
password: 'test',
firstName: 'first',
lastName: 'last'
}
(My DB entity also has the field set up as first_name and it's throwing an error)

The validation pipe的transform: true选项需要设置，以便管道返回类实例而不仅仅是经过验证的JSON。
英文:
The validation pipe's transform: true option needs to be set so that the pipe returns the class instance rather than just the validated json
