At the risk of hijacking the thread, I'd be happy to know of any
better ways that can be suggested to achieve this. For example, I've
got this method (okay, it's a get rather than set, but it's the same
idea):
alias_method :ar_creator, :creator
def creator
ar_creator || Person.find_by_sql("select 'unknown' as firstname,
'noter' as lastname, '' as othernames").first
end
I *could* check for the existence of "creator" [1] in views and other
places, but it sometimes strikes me as easier to just ensure I'm
providing a valid associated object from the model if one does not
exist.
[1] I do use guards most of the time, but on occasion, the amount of
checks for "if Model.associated_object" seems not very DRY
