[SOLVED] MVC Foolproof Validation with ASP.NET MVC WEB API project

MVC Foolproof Validation with ASP.NET MVC WEB API project

It seems Foolproof Validation does not work with WEB API:

// POST api/values
public void Post(MyModel model)
{
}    

public class MyModel
{
    public int Id { get; set; }
    public bool Condition { get; set; }
    [RequiredIfFalse("Condition")]
    public string Title { get; set; }
}

Fiddler:

User-Agent: Fiddler
Content-Type: application/json; charset=utf-8
Host: localhost:3858
Content-Length: 24


{Id: 1, Condition: true}

Response:

{"Message":"An error has occurred.","ExceptionMessage":"The method or operation is not implemented.","ExceptionType"

The same code works fine with classic MVC 4 temaplate.

Solution

No, it wouldn't...

From a quick look at the source code here the FoolproofValidator is tied to the System.Web.Mvc namespace by inheritting from System.Web.Mvc.DataAnnotationsModelValidator so this library is not going to work for WebApi.

There is a DataAnnotationsModelValidator for System.Web.Http so it might be able to be ported across but I cannot see a branch or version on the project site that has done that yet.
