Validation messages

Is it possible to get error messages? When an object doesn’t pass validation I would like to get errors messages to display, for example:

var  rules = {
  name: [ new Validator.Assert().Length( { min: 10 } ) ],
  email: [ new Validator.Assert().NotBlank() ],
  lastname: [new Assert().IsString()]
};

var model = {
  name: 'Mike',
  lastname: 'Perez'
};

var constraint = new Constraint(rules)
constraint.check(model).messages

and get

{
  name: ['Length should be greater than 10'],
  email: ['This field is required']
}

Thanks for getting back @guillaumepotier. I agree with you in not having the core have such a file but getting the possibility of defining a specific label by field (even if the constraint is the same) would make much sense for this. I’ll try to get around a solution on my own and when I feel it will be good enough, I’ll happily create a PR with it.

Hi @pgom

That’s right, it’s been some time I haven’t been here, and this topic went idle.

As of today, I’m still convinced that this should be an external new object/method maybe in a different optional file (to avoid shipping it systematically with main validatorjs core) (like discussed above) and we should use default english string file like in Parsley (with sprintf equiv to replace min/max placeholder values in the i18n strings).

These messages of course should be replaced globally AND specifically (eg: field by field, to replace “This value should not be blank” by “You must enter your name”)

I’d be glad to assist you in a PR as a reviewer, but not much more as my time is currently very short 😃
