137:         def from_json(json)
138:           set(JSON.parse(json))
139:         end
to_json(*a)

Return a string in JSON format. Accepts the following options:

:except :Symbol or Array of Symbols of columns not to include in the JSON output.
:include :Symbol, Array of Symbols, or a Hash with Symbol keys and Hash values specifying associations or other non-column attributes to include in the JSON output. Using a nested hash, you can pass options to associations to affect the JSON used for associated objects.
:naked :Not to add the JSON.create_id key to the JSON output hash, so when the JSON is parsed, it will yield a hash instead of a model object.
:only :Symbol or Array of Symbols of columns to only include in the JSON output, ignoring all other columns.
:root :Qualify the JSON with the name of the object. Implies :naked since the object name is explicit.
