Question

I want to configure a route with optional flags.

E.g. I want to be able to call the products page and send optional filters (flags) for offers and in stock options. If the flags are NOT specified then all products should be returned.

http://localhost/products

http://localhost/products/onlyOnOffer

http://localhost/products/onlyInStock

http://localhost/products/onlyInStock/onlyOnOffer

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult GetProducts(bool onlyInStock, bool onlyOnOffer)
{
    //...
}

How would I configure the route? Is it even possible in MVC 1.0? What about MVC 2.0.

Answer 1

I see 2 ways:

1) Set up 4 different Actions:

   [AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index()
{
    //...
}

    [AcceptVerbs(HttpVerbs.Get)]
public ActionResult IndexOnOffer()
{
    //...
}

    [AcceptVerbs(HttpVerbs.Get)]
public ActionResult IndexInStock()
{
    //...
}

    [AcceptVerbs(HttpVerbs.Get)]
public ActionResult IndexInStockAndOnOffer()
{
    //...
}

2) Send in the 2 parameters in the query string:
http://localhost/products/?onlyInStock=false&onlyOnOffer=true

 [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult GetProducts(bool? onlyInStock, bool? onlyOnOffer)
    {
       //...
    }
