Class Public methods
decode(json) Link
Parses a JSON
string (JavaScript Object
Notation) into a hash. See www.json.org for more info.
ActiveSupport::JSON.decode("{\"team\":\"rails\",\"players\":\"36\"}")
=> {"team" => "rails", "players" => "36"}
Also aliased as: load
parse_error() Link
Returns the class of the error that will be raised when there is an error in decoding JSON
. Using this method means you won’t directly depend on the ActiveSupport’s JSON
implementation, in case it changes in the future.
begin
obj = ActiveSupport::JSON.decode(some_string)
rescue ActiveSupport::JSON.parse_error
Rails.logger.warn("Attempted to decode invalid JSON: #{some_string}")
end
