Parse a Query String in Ruby

If you ever need to parse a query string in Ruby - or Rails, Rack has a convenient utility to do just that. parse_nested_query will parse from a string to a hash:

Rack::Utils.parse_nested_query("&sort_dir=asc&sort_by=date_created&filter_by=lead")

=>  {"sort_dir"=>"asc", "sort_by"=>"date_created", "filter_by"=>"lead"}

You can also go the opposite way with build_nested_query and generate a query string:

Rack::Utils.build_nested_query({"sort_dir"=>"asc", "sort_by"=>"date_created", "filter_by"=>"lead"})

=>  "sort_dir=asc&sort_by=date_created&filter_by=lead"
