Thank you, Reinout.
I changed the definition of 'allow_syncdb' to the following:
<code>
def allow_syncdb(self, db, model):
# db is a string of database name.
label = model._meta.app_label
if label == 'books':
dbName = 'test'
else:
dbName = None
if dbName == db:
return True
else:
return None
</code>
Now './manage.py syncdb' can run through with no problems. However, it
doesn't create the database 'test.sqlite', which means the models in the
app, books, are still installed in the default database.
Also, I am using django v1.3.
In addition, about the *two* things you mentioned, how can I test for that?
It seems all the functions defined in the class DBRouter are called
internally by django. I don't know how to make django print something so
that I know what's going on when django calls those function.
Again, thank you very much.
