Filtering Results

Hi group,

I’ve got a question regarding filtering with EZ-Where and link_to. I have a Category model and a Car model. If you visit the cars listing, you see a list of all cars, regardless of which category they are in. There is a form on the page to filter through these, which is passed to EZ::Where for the filtering. The question I have, is I pass the params to EZ-Where with car[:category_id], so if I wanted to allow people to click a link on the category page to view all cars in that category (which is just a link_to to the cars page) how would I pass the car[:category_id]? Am I overlooking something stupid and simple?
