adding more details to Exception object

rubyonrails-talk
1

I know that the default ruby Exception object holds message and backtrace.

Sometimes I want to specify variable names and values to the Exception object so that I can email myself the details in the exception_notifier.

I know I could subclass Exception to add more details to it, but I dont want to have to recreate all the classes for exceptions that already exist (ArgumentError,IOError, etc).

I also know that I could tack on all the info in the message but that would get very messy since the message is usually in the subject of my error emails.

I want to be able to do :

raise ArgumentError.new(msg, details)

Should I try something like

class Exception attr_accessor :details def initialize(msg, details)

end end

which probably wont work since its a builtin function and there is only stub code for it.

Make your own exception:

class CustomException < StandardError     attr :message, :details     def initialize(message, details)     @message = message     @details = details     end end
