I need to create exceptions that do something already by default and have the same behavior as Standarterror

Question

Hello,

I work with Rails and use Sentry to log errors from my applications automatically. When an exception is thrown the error is not generated, so I have to force the error capture through the command:

Raven.captureMessage(e.message, level: 'error')

However I would not like that in almost every Exception have to repeat this line.

I tried to create a class to avoid repetition, but I ended up not succeeding, follow my attempt (file created in lib/raven_error.Rb):

class RavenError < StandardError
    def initialize exception
        super
        Raven.captureMessage(exception.message, level: 'error')
    end
end

Sample controller:

    def create
    @user = User.new(user_params)

    begin
        @user.save
    rescue RavenError => e
        render :new
    end

I would like the captureMessage method to be executed when instantiating the Ravenerror exception, without having to order inside every.
