You'll need to post actual code and error stack traces if you want people
to help.

I am in the process of setting up a django server. I am trying to connect
our 4 legacy DBs to her. I have created a separate app for each DB, added
the app_label to the meta of the model and wrote a read only router for
each db. This was working fine until i got to the last one. The routing is
Hi Philip,
I'm not sure your sharding will be possible in the way you describe it.
There will be cases for which selecting the database will not be possible. For
example, Customer.objects.get(name=) won't be able which DB you'll need to
hit to get the result.
Same goes for a new Customer. H
Hello list,
In my database, I have a `Customer` table defined in my database that all
other tables are foreign keyed on.
class Customer(models.Model):
...
class TableA(models.Model):
Customer = models.ForeignKey(Customer)
...
class TableB(models.Model):
What I did is create an attribute in my models and called it
model.py
class Data(models.Model):
# connection_name is my database name which points to the name from
settings.py
connection_name = "gis"
name = models.CharField(max_length=50)
area = models.IntegerField()
and created a
The only solution I can directly think of, since the SITE_ID is in
settings.py would be to use some python logic to determine the
database for that site.
eg.
if SITE_ID == 1:
... Database settings for site 1 here ...
Use an if-then like this in your settings.py.
Now if what your going after
I had a kind of crazy idea and I wanted to bounce it off of some
people with a lot more django experience than I.
Here's my scenario...
I would like 1 code base, this code base services potentially hundreds
of businesses, each of which I want to have a copy of the same schema
but with data only r
Russ,
Your gut feeling confirms my suspicion.
Changing the lines to the following fixes my problem:
db = model_instance._state.db
if db is None:
db = router.db_for_write(model_instance.__class__,
instance=model_instance)
qs =
self.rel.to._default_manager.using(

I didn't work with multidb but I think it is possible anyway... try it using
additional middleware... for example.. change dynamically db settings...

Hello,
In my application a number of databases are configured with identical
schemas.

cookie.
An object with the same primary key can be created in each schema by
