Hi, I have been playing with object.to_json to searilise my objects into JSON notation. How does one deserailise these JSON strings back into ruby objects?

I has assumed that rails could handle it without the gem as it does serialisation.

When I install ''JSON'' it seems to overload the to_json method. My active record models now serialise as: "#" instead of the original to_json output of: {"vehicle_ids": [3, 6, 5]} Does the ''JSON'' library work with complex objects?

Sorry, the to_json output from the ''JSON'' library is: "#<Cart:0x2475448>" not "#" as I stated above -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
