Rails routes with multiple identifiers?

I'm trying to set up routes in Rails 3 that look like:

/items/:category/:name/

It's pretty easy to do a match to set this up, and then generate the URL with the following:

item_path(:category => @item.category, :name => @item.name)

But is there an开发者_开发问答y way to set it up so that item_path @item and form_for @item will work automatically, so I don't have to pass the category every time?

Thanks!

Not really no. I would suggest defining a to_params (note the 's') method on Item as follows:

def to_params {:category => category, :name => name} end

And then calling it like so item_path(@item.to_params). If you hack things to default to this I can guarantee you'll run into situations in which you don't want it.
