Rails - Feb 2007 - Always eager load

Is it possible to make a model always eager load an association,
without explicitly specifying it every time? For example:

class Article < AR::Base
  has_one :author
end

I''m *always* going to need the Author for the Article, so is there a
way to set :include => :author by default for find()? I thought about
overwriting find() on Article and then just call super() with
the :include, but I''m not exactly sure how that would go. Any ideas?

Thanks

This seems to work:

def self.find(*args)
  options = extract_options_from_args!(args)
  options[:include] ||= :author
  super(args.first, options)
end

Is there an easier way or are there any problems with this approach?

Thanks

If there''s already an options[:include] you''re going to use it
then, right?
[That''s what the code says.] If you''re wanting to append it to
any other
manual :include, you''ll need to convert options[:include] to an array
and
all. If there''s no other possible models to include then you could
options[:include] = :author instead. But I''d say you''ve got it
solved
already.

Actually, it''s the opposite, if there is an :include defined then it
does nothing, this way I can specify :include => nil if I didn''t
want
to eager load (which won''t happen, but just in case). That seems to do
the job then, thank you.
