Instance Method Details

#create_record(attribute_names = nil) ⇒ Object

This override ensures that pkeys are set on the instance when records are created. However, while ActiveRecord::Persistence defines a create_record method the call in create_or_update is actually calling the method create_record in the Dirty concern which removes the pkey attrs and also sets updated/created at timestamps For some reason when we overide here we lose dirty! So, for now, timestamps are recorded explicitly
