Just realised why I couldn't reproduce it - I had a temporary hack in
the Elixir source to work around. Here's the test case:
from elixir import *
class T1(Entity):
has_field('test', Integer, primary_key=True)
has_one('t2', of_kind='T2')
class T2(Entity):
belongs_to('t1', of_kind='T1', colname='bob', primary_key=True)
T1.select()
And this is the patch I'm using (not ready for commit just yet!)
