Hello,
Here is an extremely simple scenario:

f1 = models.CharField(max_length=64)
class A(Base):
f2 = models.CharField(max_length=64)
class B(models.Model):
f3 = models.CharField(max_length=64)

Hi all - I'm trying out the multi database options in django 1.2 beta

Remember you can also write your own login/logout/... views but still

Hi. All that you say is totally clear to me, but I tried to suit the

To clarify. If I have three houses, and house 120 has two

If the query matches one reservation of house 120 i get a list like

House 120 should been excluded from the list though.

Look at the way contexts are implemented. There are actually a chain of
mappings, and if a variable isn't found in the mapping at the head of the
chain, the next is consulted, and so on. Certain operations (and, apparently,
ifequal is one of them) push a new mapping onto the chain, so when that

Maybe feed your templates through a call to unicode.decode, with the
