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

Hello,

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

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

But I would not want that in almost every exception to have to repeat that line.

I tried to create a class to avoid repetition, but I did not succeed, it follows my attempt (file created in lib / raven_error.rb):

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

Controller example:

    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 by instantiating the RavenError exception, without having to be inquiring into every rescue I have.
