How to handle null {id} on route?
- by MattSlay
What if a user hits my site with http://www.mysite.com/Quote/Edit rather than http://www.mysite.com/Quote/Edit/1000 In other words, they do not specify a value for {id}. If they do not, I want to display a nice "Not Found" page, since they did not give an ID. I currentl handle this by accepting a nullable int as the parameter in the Controller Action and it works fine. However, I'm curious if there a more standard MVC framework way of handling this, rather than the code I presently use (see below). Is a smoother way to handle this, or is this pretty mush the right way to do it?
[HttpGet]
public ActionResult Edit(int? id)
{
if (id == null)
return View("QuoteNotFound");
int quoteId = (int)id;
var viewModel = new QuoteViewModel(this.UserId);
viewModel.LoadQuote(quoteId);
if (viewModel.QuoteNo > 0)
{
return View("Create", viewModel.Quote.Entity);
}
else
return View("QuoteNotFound");
}
