I have used validator required field in my model as follow and its working
[Required(ErrorMessage = "Description is required.")]
public string Description { get; set; }
Now i have another property of integer array type
public string[] Roles { get; set; }
I am not able to get how can i put required field validator on integer array ?
Personally i don't like using attributes for model validation,
You can use fluent validation http://fluentvalidation.codeplex.com/
So the validation logic is gathered at one place and doesn't pollute the model.
Write a custom validation attribute.
I've not tested but try code like this :
public class RequiredArray : ValidationAttribute
{
public override bool IsValid(object value)
{
var list = value as IList;
if (list != null)
{
return list.Count > 0;
}
return false;
}
}
[RequiredArray (ErrorMessage = "Roles is required.")]
public string[] Roles{ get; set; }
