convert ruby hash to URL query string … without those square brackets

Question

In Python, I can do this:

>>> import urlparse, urllib
>>> q = urlparse.parse_qsl(\"a=b&a=c&d=e\")
>>> urllib.urlencode(q)
\'a=         


        

Answer 1

Quick Hash to a URL Query Trick :

"http://www.example.com?" + { language: "ruby", status: "awesome" }.to_query

# => "http://www.example.com?language=ruby&status=awesome"

Want to do it in reverse? Use CGI.parse:

require 'cgi' 
# Only needed for IRB, Rails already has this loaded

CGI::parse "language=ruby&status=awesome"

# => {"language"=>["ruby"], "status"=>["awesome"]}
