Multiple database and AutocompleteForeignKey = 'incorrect table name'

[vital.fadeev@…]

I need your help.

I describe two models. One in MySQL. And one in Oracle.
While save I get error: (1103, Incorrect table name USERS_V)
I.e. model 'User' look in to MySQL.

Databases:
Oracle

• table USERS_V

MySQL

• table realtors

Models:

# MySQL
class Realtor(models.Model):

realtor_id = AutocompleteForeignKey(User, db_column='realtor_id',

primary_key=True,
verbose_name=u'Realtor')

class Meta:

db_table = 'realtors'

# Oracle
@using('fe_test')
class User(models.Model):

id_user = models.PositiveIntegerField(u'ID', db_column='id_user', primary_key=True)

class Meta:

db_table = "USERS_V"

My router:

class Router(object):

def _by_applabel(self, model, hints):

app_label = model._meta.app_label
if app_label in settings.DATABASES:

return app_label

else:

return fallback

def db_for_read(self, model, hints):

if model in using_map:

return using_map[model]db_read

else:

return self._by_applabel(model, hints)

def db_for_write(self, model, hints):

if model in using_map:

return using_map[model]db_write

else:

return self._by_applabel(model, hints)

def allow_relation(self, obj1, obj2, hints):

return True

# Model Decorator "using"
using_map = {}
def using(db_read, db_write=None):

"""
Model class decorator for directing into specific databases.
"""

if db_write is None:

db_write = db_read

def using_decorator(model):

using_map[model] = {

'db_read': db_read,
'db_write': db_write,

}
return model

return using_decorator

I use decorator 'using'. It work. But not work with AutocompleteForeignKey Fields.
What I can do for solve this task?
