How to store hash in session in Ruby

I'm开发者_运维知识库 looking for a way to serialize a hash so it can be stored in a Sinatra flash session. Does anyone have any idea? Thanks.

Serialize your Hash to a JSON or YAML string and store that. This assumes that you don't have anything crazy in your Hash like a lambda or a Thread that cannot be serialized.

Might want to read this for ideas:

Personally, I use json for most of my client-facing objects that come from ruby.
