asp.net mvc dynamic validation depending on action

I have a view model like so:

public class AccountView {
  public int AccountId { get; set; }
  [Required]
  public string AccountName { get; set; }
}

But I would like the AccountName field to be required only if the action is "Edit", but not "Create". How is this accomplished in asp.net mvc3?

thanks.

Or you could simply have two different ViewModels: one for the Edit action and one for the Create action. I don't think it's a bad practice even if you duplicate code (not all obviously), as a ViewModel should be tied to the View it's modeling.

You can implement a custom validator. Once inside the Validate method you will have access to properties like, (((System.Web.Mvc.ModelValidator)(this))).ControllerContext.Controller where you can look into the ContollerContext, ViewData, etc. You also have access to properties like

  • (((System.Web.Mvc.ModelValidator)(this))).ControllerContext.RequestContext
  • (((System.Web.Mvc.ModelValidator)(this))).ControllerContext.HttpContext
  • (((System.Web.Mvc.ModelValidator)(this))).ControllerContext.RouteData
