This made me think, wouldn't-it-be-nice-if...

...you could declare the default of an association?

The reason I say this is that while defaulting a foreign key property  
works if you save immediately, it doesn't let you build object graphs  
in memory.  I've been bitten by a bug I let creep in by setting  
properties directly, that lurked for a while until we finally fixed it  
by loading all the associated objects.  (In general, I've found using  
ids in the domain model dangerous.)

I'm thinking something like this:

   belongs_to :job_role,
              :default => lambda { |r, p| JobRole.first(:name =>  
"Boss" ) }

I wrote a spec[1] not long ago to see if the behaviour existed - which  
it doesn't - but I wasn't sure about putting it on Lighthouse.   
WDYAT?  Worth filing a ticket?
