Proposal to expose a class or object of ActiveModel::Errors caller

ActiveInteraction and a big amount of other frameworks are using ActiveModel::Errors to implement errors.

When combined with other gems or frameworks that are using ActiveModel it is difficult to find out what class have called ActiveModel::Errors.new(self). For example the following case:

module MyAwesomeFramework class Errors < ActiveModel::Errors def merge!(other_instance_of_active_model_errors) if other_instance_of_active_model_errors.called_by? User # User is an ActiveRecord::Base # Use ActiveModel’s error translations else # Do magic to decide what translations to use end end end end

``

That is why I propose to expose something like

class ActiveModel::Errors

#…

def called_by?(klass) caller.class == klass end

def caller @base end

#…

end

``

Not sure about the name of method however.

Thanks in advance,
