I have two models, one is for categories, the other is for posts. I want to group them like mysite.com/category/postID

The category model shares a $belongsTo relationship with the posts modal. What's the best practice if I wanna group the categories to the posts and display in url like this?

I take it I need to make a page. set url and add the component, but not sure how to generate the URL.

Thanks for reading :)
