  2. import dejavu
  3. class Zoo(dejavu.Unit):
  4.     Name = dejavu.UnitProperty()
  5.     Size = dejavu.UnitProperty(int)
  7.     def total_legs(self):
  8.         return sum([x.Legs for x in self.Animal()])
  9. class Animal(dejavu.Unit):
  10.     Legs = dejavu.UnitProperty(int, default=4)
  11. Animal.set_properties({"Name": unicode,
  12.                        "ZooID": int,
  13.                        })
  14. Animal.many_to_one('ZooID', Zoo, 'ID')
  15. # Set up a global Arena object.
  16. arena = dejavu.Arena()
  17. conf = {u'Connect': r"PROVIDER=MICROSOFT.JET.OLEDB.4.0;DATA SOURCE=C:\zookeeper.mdb;"}
  18. arena.add_store("main", "access", conf)
  19. arena.register_all(globals())
I don't know "self.Animal()" what it means. why it can write as such?
how do I write the code if I want to connect sqlite db?
