Error "Validation.js Error: This library (validator.js) validates strings only" on number field

[fabiobeoni]

Hello,

I'm getting this error on a number field on my class:

Some model class...

@IsIn([
      Difficulties.EASY,
      Difficulties.MEDIUM,
      Difficulties.DIFFICULT
    ])
    public difficulty:number;

export class Difficulties {
  static EASY:number=0;
  static MEDIUM:number=1;
  static DIFFICULT:number=2;
};

According to this post looks like the validator.js library doesn't work anymore with fields that are not STRING: validatorjs/validator.js#505

Thanks, F.

Hi @fabiobeoni!

I am going to close this as I cannot reproduce this issue with the current release.

import { IsIn, validate } from 'class-validator';

export class Difficulties {
  static EASY: number = 0;
  static MEDIUM: number = 1;
  static DIFFICULT: number = 2;
};

export class TestClass {
  @IsIn([
    Difficulties.EASY,
    Difficulties.MEDIUM,
    Difficulties.DIFFICULT
  ])
  public difficulty: number;
}

const instance = new TestClass()
instance.difficulty = 9

validate(instance).then(console.log);

This will return with the correct error:

difficulty must be one of the following values: 0,1,2
