I have created a simple custom JsonConverter - code below - to simply change the error message generated when an invalid date is passed.
This is being used in an ASP.Net MVC site and also ASP.Net Web API for Ajax calls.
I am posting a DTO (partial code below) via ajax. When i do this on my local environment everything functions as it should; when the date is invalid I receive a bad request along with the correct error message
When i publish this to a production server it's totally ignored and i receive the default ModelState list of errors.
I have verified my web.config and Newtonsoft versions; they're the same both locally and on the server.
Why would the converter be ignored on production?
Converter is:
public class CustomDateValidationConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return true;
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (string.IsNullOrEmpty(reader.Value.ToString()))
return null;
DateTime d;
DateTime.TryParse(reader.Value.ToString(), out d);
if (d == null || d == DateTime.MinValue)
throw new Exception(string.Format("{0} is invalid", reader.Path.AddSpacesBeforeUppercase(true)));
return d;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
serializer.Serialize(writer, DateTime.Parse(value as string));
}
}
I am using it in my DTO as:
.....
[JsonConverter(typeof(CustomDateValidationConverter))]
[DateLessThanOrEqual("CreateDateTo", "Create Date From must be on or before Create Date To")]
public DateTime? CreateDateFrom { get; set; }
.....
