I’m using stringscanner on my request URL in order to get the name of the user’s currently selected category, but I’ve been having difficulty dealing with spaces and special characters.

request.url.scan(/\?category=\w+/).to_s.gsub('?category=', '')

URL examples followed by result

http://localhost:3000/search?category=dog&search=&utf8=%E2%9C%93 => ["dog"]
http://localhost:3000/search?category=dog.com&search=&utf8=%E2%9C%93 => ["dog"]
http://localhost:3000/search?category=dog+cat&search=&utf8=%E2%9C%93 => ["dog"]

I’m trying to get [“dog”] [“dog.com”] and [“dog cat”], but am currently stuck. Any ideas?

Note: Considering removing spaces from categories and replacing them with dashes as multiple spaces could be problematic, but if it’s possible to create one function to rule them all, that would be awesome.

    This is Rails, is there a reason you’re not just using params[:category]?
