But I want after categories/category_name .

I don't want that You say me everything, I just need some tip. So I could do the research.

Answer 1

You can use the friendly_id gem to achieve that. You will find all the explanation you need to implement this feature in this Railscasts episode.

Or you can do it manually by following this other Railscasts episode.

Answer 2

If the category_name is something that can be placed in url (like no spaces and so) you can achieve that by simply overriding to_param method in your model

class Category
  def to_param
    category_name
  end
end
