Anyone know if I can put a hash in the cookie?
Something like this: cookies [: test] = {: top => 5,: middle => 3,: bottom => 1}
Thanks
I woud look into serializing the hash to store it. Then deserialize it to retrieve it.
When you serialize a hash, the result will be an encoded string. This string can be decoded to get the original object back.
You could use YAML or JSON for this. Both are nicely supported in Ruby.
A YAML example
require "yaml"
cookies[:test] = YAML::dump {a: 1, b: "2", hello: "world"}
# => "---\n:a: 1\n:b: '2'\n:hello: world\n"
YAML::load cookies[:test]
# => {a: 1, b: 2, c: "world"}
cookies[:test] = JSON.generate {a: 1, b: "2", hello: "world"}
# => '{"a":1,"b":"2","hello":"world"}'
JSON.parse cookies[:test]
# => {"a"=>1, "b"=>"2", "hello"=>"world"}
Note: when using JSON.parse
, the resulting object will have string-based keys

There are a number of ways which it is possible (i.e. storing a string and eval
ing that value, SCARY!). This is a simple way.
cookies[:test_top] = 5
cookies[:test_middle] = 3
cookies[:test_bottom] = 1
You can also convert to JSON and then parse it when loading the cookie.
Newer versions of Rails include automatically serialization using the session object.
