Question

I have a string like this:

\"foo=bar&bar=foo&hello=hi\"

Does Ruby on Rails provide methods to parse this as if it is a querystring,

Answer 1

Edit : as said in the comments, symolizing keys can bring your server down if someone want to hurt you. I still do it a lot when I work on low profile apps because it makes things easier to work with but I wouldn't do it anymore for high stake apps

Do not forget to symbolize the keys for obtaining the result you want

Rack::Utils.parse_nested_query("a=2&b=tralalala").deep_symbolize_keys

this operation is destructive for duplicates.
