Question

In handling a form post I have something like

    public ActionResult Insert()     {         Order order = new Order();         BindingHelperExtensions.UpdateFrom(order, this.Request.Form);          this.orderService.Save(order);          return this.RedirectToAction('Details', new { id = order.ID });     } 

I am not using explicit parameters in the method as I anticipate having to adapt to variable number of fields etc. and a method with 20+ parameters is not appealing.

I suppose my only option here is mock up the whole HttpRequest, equivalent to what Rob Conery has done. Is this a best practice? Hard to tell with a framework which is so new.

I’ve also seen solutions involving using an ActionFilter so that you can transform the above method signature to something like

[SomeFilter] public Insert(Contact contact)

I’m now using ModelBinder so that my action method can look (basically) like:

    public ActionResult Insert(Contact contact)     {          if (this.ViewData.ModelState.IsValid)         {             this.contactService.SaveContact(contact);              return this.RedirectToAction('Details', new { id = contact.ID });         }         else         {             return this.RedirectToAction('Create');         }     }
