[Re BR]

I have the following hash myhash
{ "inter" => "team", "shirt" => "stripe" }

desired output

inter=team&shirt=stripe

I tried url_for myhash but got undefined method `url_for' for

thanks

The single line answer would be

hsh = { "inter" => "team", "shirt" => "stripe" }
hsh.to_a.map{|e| e.join('=')}.join('&') # 'inter=team&shirt=stripe'

Broken down

hsh = { "inter" => "team", "shirt" => "stripe" }
ary = hsh.to_a #[['inter', 'team'], ['shirt', 'stripe']] - take the hash and
switch into array
new_ary = ary.map{|e| e.join('=')} #['inter=team', 'shirt='stripe'] - take
the array and join the inner arrays using a =
final = new_ary.join('&') # 'inter=team&shirt=stripe' take the remaining
array and join the element with &

Hi --

The single line answer would be

hsh = { "inter" => "team", "shirt" => "stripe" }
hsh.to_a.map{|e| e.join('=')}.join('&') # 'inter=team&shirt=stripe'

No need for the to_a. You'll get a [key,value] array in e each time
through by just mapping the hash.

Note that the order might come out different; for example, on my
machine anyway:
=> "shirt=stripe&inter=team"

though I suspect it doesn't matter in this case.

The correct way escapes the `=' and `&' signs. I wrote my own
library and it seems that it doesn't. Ugh.

Hi,
I think I had faced the same issue before for encoding, I have used this
method for encoding urls.

require 'rubygems'
require 'rest-open-uri'
require 'uri'
require 'cgi'

def form_encoded(hash)
encoded = []
hash.each do |key, value|
encoded << CGI.escape(key) + '=' + CGI.escape(value)
end
return encoded.join('&')
end

representation = form_encoded({ "user[name]" => username,
"user[password]" =>
password,
"user[full_name]" =>
full_name,
"user(e-mail address removed)
