Dumps objects in JSON
(JavaScript Object

# => "{\"team\":\"rails\",\"players\":\"36\"}"
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.

rescue ActiveSupport::JSON.parse_error
Rails.logger.warn("Attempted to decode invalid JSON: #{some_string}")
