Trying to override assocation find

Hey Guys,
I’m stumped with something, hoping somebody can help.

Basically, I’m trying to override the default belongs_to accessor.

For example, I have an Event model, that belongs_to a Venue:

class Event < ActiveRecord::Base
belongs_to :venue


The venue is not always set, so sometimes “event.venue” returns null.
I want to be able to override “event.venue”, and provide my own code
that grabs the venue if it doesn’t exist. I was thinking I could do
something like:

def venue
if self.send(:venue) == nil
# code to fetch the venue and insert into db

Clearly though, this doesn’t work, because self.send(:venue) just calls
itself, and ruby barfs on a stack overflow from the recursion.

The workaround is to create a “get_venue” method, and always call that
instead of “venue,” but that seems kind of icky.

Any ideas?
