I have a model similar to the following:
class Item(Model):
name = CharField()
fieldA = CharField(null=True)
fieldB = CharField(null=True)
class ItemHolderA(Model):
item = ForeignKey('Item')
class ItemHolderB(Model):
item = ForeignKey('Item')
Then I attempt the following:
item = Item.objects.create(name='ItemOne')
holderA = ItemHolderA.objects.create(item=item)
...
item = Item.objects.get(name='ItemOne')
holderB = ItemHolderB.objects.create(item=item)
...
holderA.item.fieldA = 'Foo'
holderA.item.save()
holderB.item.FieldB = 'Bar'
holderB.item.save()
What I end up with n the db is item.fieldA = None because the item in
holderB is a different object than the one in HolderA.
I've only been using Django for a few months now, so I'm sure I'm
missing something obvious. I was a bit surprised there was no object
caching, but barring that I couldn't find a way to make sure the
objects were kept in sync. Any help on this issue would be
appreciated.
