Routing - newbie question about shorting the url

Hi Right now I have my url showing as the following: http://localhost/categories/italian/recipes/special-pasta-sauce

I would like it to be: http://localhost/categories/italian/special-pasta-sauce (or even http://localhost/italian/special-pasta-sauce)

my category model has_many :recipes and my recipes model belongs_to :category (for the purposes of my test project a recipe can only belong to one category)

Is this possible in RoR? Any pointers?

This is possible but you will basically be setting up a rule like this

"whenever we get a url like /foo/bar then we want the category 'foo' and the recipe 'bar'"

That might clash with the existing url schema on your site. If you want to go for it though then set up your routes like this:

  map.category_recipe ':category_name/:recipe_name', :controller => 'recipes', :action => 'show', :conditions => {:method => :get}

Make sure you put it down the bottom, above the

  map.connect ':controller/:action/:id'

section.

Now the url http://localhost/italian/special-pasta-sauce

should call the recipes controller, with params like {:recipe_name => "special-pasta-sauce", :category_name => "italian"}

And in your views you can say eg category_recipe_path(category, recipe)

The above assumes that you've overriden to_param in Category and Recipe to use the name of the object instead of it's id.

If you're using slus or something instead of name then you can substitute appropriately.
