MVC 3 Razor - ICollection Validation Issue
Please Sign up or sign in to vote.
3.00/5 (3 votes)
I'm trying to validate a dynamically generated Radio Button Groups for a Survey that the answers and questions are dynamically generated too, but when I try to submit the form the validator message appears but isn't functioning right because I'm making a mistake with the jQuery implementation or the method of validation.

I want to validate (unobstrusive) each answer by question generated in the form after submit, like the other field's (CodChofer, CodUsuario).


I have this model:

C#
[Table("Encuesta")]
    public class Encuesta
    {
        [Key]
        public int IdEncuesta { get; set; }

        [Required(ErrorMessage = "El código del chofer es requerido.")]
        [Display(Name = "Código de chofer")]
        [MaxLength(7, ErrorMessage = "Código de chofer debe ser de máximo 7 dígitos.")]
        [MinLength(7, ErrorMessage = "Código de chofer debe ser de mínimo 7 dígitos.")]
        public string CodUsuario { get; set; }
        [Required(ErrorMessage = "El código de usuario es requerido.")]
        [Display(Name = "Código de usuario")]
        [MaxLength(7, ErrorMessage = "Código de usuario debe ser de máximo 7 dígitos.")]
        [MinLength(7, ErrorMessage = "Código de usuario debe ser de mínimo 7 dígitos.")]
        public string CodChofer { get; set; }

        public virtual ICollection<Pregunta> Preguntas { get; set; }
        [MultipleRequiredValues(ErrorMessage = "Debe elegir una respuesta por pregunta")]
        public virtual ICollection<Respuesta> Respuestas { get; set; }

        public string Observaciones { get; set; }

        [ReadOnly(true)]
        [DataType(DataType.Date)]
        public DateTime Fecha { get; set; }

        [ReadOnly(true)]
        public int Puntuacion { get; set; }

        public Encuesta()
        {
            this.Fecha = DateTime.Now;
        }
    }


I have this custom validator:

C#
namespace SSU.DAL.Validators
{
    [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)]
    public class MultipleRequiredValuesAttribute : RequiredAttribute, IClientValidatable
    {
        #region IClientValidatable Members

        public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
        {
            var clientValidationRule = new ModelClientValidationRule()
            {
                ErrorMessage = base.ErrorMessage,
                ValidationType = "multiplerequiredvalues"
            };

            return new[] { clientValidationRule };
        }

        #endregion
    }
}

I think this piece of code just validates the last input or select, if it has a value then validation passes. Also from all the examples i have seen, this should not be inside document ready.

(function ($) {
$.validator.addMethod('multiplerequiredvalues', function (value, element) {
if ($(element).is(':visible')) {
var returnVal = true;
var name = $(element).attr('name');
var elements;
if ($(element).is('input')) {
elements = $('input[name=' + name + ']');
}
else {
elements = $('select[name=' + name + ']');
}
elements.each(function () {
if ($(this).is(':visible')) {
returnVal = $(this).val() != "" && $(this).val() != null;
}
});
return returnVal;
}
else {
return true;
}
});
$.validator.unobtrusive.adapters.addBool("multiplerequiredvalues");
} (jQuery));

I have this code, as a self function, in my View already but isn't working... :(

But like i said this code just validates the last input or select. Try the following:

$.validator.addMethod('multiplerequiredvalues', function (value, element) {
if ($(element).is(':visible')) {
var name = $(element).attr('name');
var elements;
if ($(element).is('input')) {
elements = $('input[name=' + name + ']');
}
else {
elements = $('select[name=' + name + ']');
}
var numOfEmptyInputs = 0;
elements.each(function () {
if ($(this).is(':visible') && !$(this).val()) {
numOfEmptyInputs++;
}
});
if(numOfEmptyInputs > 0)
return true;
else
return false;
}
else {
return true;
}
});
$.validator.unobtrusive.adapters.addBool("multiplerequiredvalues");

oops replace if(numOfEmptyInputs > 0) with if(numOfEmptyInputs > 1)
huotari 4-Oct-12 5:17am    
and don't place these $.validator.addMethod and $.validator.unobtrusive.adapters.addBool inside document ready
