Display the Result of RemoteAttribute in MVC 3.0
I have a ViewModel setup to use RemoteValidation using the RemoteAttribute
. It works fine.
EDIT
Updated it a bit to show some fixed code.
I want to point out that this is not my actual "Register" code. This is testing it so I can use it in other situations. I'm not having users register using flat names!
Here are the libraries I am referencing, and how I am referencing them.
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js"></script>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.10/jquery-ui.js"></script>
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery.validate/1.7/jquery.validate.min.js"></script>

<script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/mvc/3.0/jquery.validate.unobtrusive.min.js"></script>
Here is how I am wiring the RemoteAttribute.
public class UserRegistrationModel
{
[Required]
[RegularExpression(@"^(?:[a-zA-Z\p{L} \.'\-]{3,48})$", ErrorMessage = "This name contains invalid characters. Names must be between 3 and 48 characters, contain only standard unicode symbols, and may not contain any punctuation other than the ['] and [-] symbols.")]
[Remote("ValidateUserName", "Membership", ErrorMessage = "{0} is invalid.")]
public string Name
{
get;
set;
}
}
And then here is the actual controller behavior.
public ActionResult ValidateUserName(string name)
{
// perform logic
if (true)
return Json(true, JsonRequestBehavior.AllowGet);
return Json(false, JsonRequestBehavior.AllowGet);
}
I have inspected my HTML, and this functions as I want. But I don't understand what to do from there. How can I display that information to the user? It just stores it in the html
data-val-remote="* is invalid"
I have watched, and I notice that even when the RemoteAttribute
returns false, the html changes from
value
to value class="valid"
, but in my other model validations, this changes to `class="input-validation-error"'.
So does anyone have any clues on how to draw the remote message back? Or is there really nothing I can do?
The following works fine for me:
public class UserRegistrationViewModel
{
[Required]
[RegularExpression(@"^(?:[a-zA-Z\p{L} \.'\-]{3,48})$", ErrorMessage = "This name contains invalid characters. Names must be between 3 and 48 characters, contain only standard unicode symbols, and may not contain any punctuation other than the ['] and [-] symbols.")]
[Remote("ValidateUniqueName", "Home")]
public string Name { get; set; }
}
Controller:
public class HomeController : Controller
{
public ActionResult Index()
{
return View(new UserRegistrationViewModel());
}
public ActionResult ValidateUniqueName(string Name)
{
if (NameIsValid(Name))
{
return Json(true, JsonRequestBehavior.AllowGet);
}
return Json(string.Format("{0} is invalid", Name), JsonRequestBehavior.AllowGet);
}
}
View:
@model AppName.Models.UserRegistrationViewModel
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
@using (Html.BeginForm())
{
@Html.TextBoxFor(x => x.Name)
@Html.ValidationMessageFor(x => x.Name)
<input type="submit" value="OK" />
}
