class-validator doesn't validate entity

Question

Can I use class-validator to validate Entity columns?

This doesn't validate the columns:

import { IsEmail } from 'class-validator';

@Entity()
export class Admin extends BaseEntity {

  @Column({ unique: true })
  @IsEmail()
  email: string;

}

However when I use the class-validator anywhere else in the code other than entities it validates properly and doesn't allow for bad inputs.

This works:

@InputType()
export class RegisterInput {

  @Field()
  @IsEmail()
  email: string;

}

Answer 1

The Entity should be clean

@Entity()
    export class Admin extends BaseEntity {
    
      @Column({ unique: true })
      email: string;
    
    }

While you define a DTO for checking the incoming request.

export class AdminDto {

@IsEmail() 
email: string;

}

In your controller, you would check the incoming request with your AdminDto.

@Controlller('route')
export class AdminController {
constructor(private yourService: yourserviceClass)

@Post('/api')
async createSomething(@Body('email', ValidationPipe) email: string){ //Your request body //would be checked against your DTO
this.yourService.createMethod(email)
}

Hope this answers your question.
