Hi All,

I have been pulling my hair out trying to get this one working. I am not to sure of the inheritance structure of UmbracoApiController, but I assume at some point it inherits from ApiController. I have created a Validation Filter attribute that will validate against the model state. I have added my model into the model folder and set the appropriate validation attributes on the model. However ModelState never seems to populate or contain my model.

Any ideas?

Here is my WebApi Class:

public class LeadCaptureApiController : UmbracoApiController
{
    [ValidateModelFilter]
    public HttpResponseMessage ProcessLead(NewLead newLead)
    {
        var results = Leads.Api.Leads.NewLead(newLead.Name, newLead.Email, newLead.PhoneNumber, newLead.State);
        return Request.CreateResponse(HttpStatusCode.Created, newLead);
    }
}

and here is my Filter Class:

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
    public class ValidateModelFilterAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(HttpActionContext actionContext)
        {
            if (actionContext.ModelState.IsValid == false)
            {
                actionContext.Response = actionContext.Request.CreateErrorResponse(
                 HttpStatusCode.BadRequest, actionContext.ModelState);
            }
        }
    }

and finally my Model

public class NewLead
{
    [Required]
    [Display(Name = "Name")]
    public string Name { get; set; }

    [Required]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Email")]
    public string Email { get; set; }

    [Required]
    [DataType(DataType.PhoneNumber)]
    [Display(Name = "Phone Number")]
    public string PhoneNumber { get; set; }

    [Required]
    [DataType(DataType.Text)]
    public string State { get; set; }
}
