same class name in two applications in different projects
Hi. I have some problem i cant figure out. I have two separate apps in separate projects. I want to write script that uses both apps. Problem is that in models i have two different classes with same name (call it C). So to make it short i have something like this: from projA.appA.models import C as C1 from projB.abbB.models import C as C2 C2 is equal C1. So i guess that framework does some magic behind the scenes and does not import class again. Seems like it uses only class name not full class path. Can anyone tell me where should i look for to see why this is happening? Cheers --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

mysql problems - guess not, but still :)
Hi. We have some intresting situations in one of our environments. 1. When we generate request that causes object not found errors after 5 such requests we get info that we cannot connect DB. Looks like some connection limitation but we cant reproduce it in other environments. 2. Occures when user has opened browser (opened session i guess) during apache restart. After restart when user is refreshing page content receives information that he can't connect to db. We are using django.contrib.auth and django.contrib.sessions Does anyone has similar issues, or maybe know origins of such behave.

Re: connecting to multiple databases
I had an data import task for django application. Client moved data
from several databses into new one. All legacy databases had same
model, so there was proper django model created for them. And I had
problem with importing data from all those legacy system. I've sniffed
a bit and on the base of django code created something like this:
#Script for switching connections between databases
import django
import types
import MySQLdb as Database
from django.db.backends import util
from MySQLdb.constants import FIELD_TYPE
from MySQLdb.converters import conversions
django_conversions = conversions.copy()
django_conversions.update({
types.BooleanType: util.rev_typecast_boolean,
FIELD_TYPE.DATETIME: util.typecast_timestamp,
FIELD_TYPE.DATE: util.typecast_date,
FIELD_TYPE.TIME: util.typecast_time,
})
def switch(_conf):
instance = django.db.connection
try:
instance.connection.close()
except AttributeError:
pass
instance.connection = None
def cursor():
if not instance._valid_connection():
kwargs = {
'user': _conf['DATABASE_USER'],
'db': _conf['DATABASE_NAME'],
'passwd': _conf['DATABASE_PASSWORD'],
'conv': django_conversions,
}
if _conf['DATABASE_HOST'].startswith('/'):
kwargs['unix_socket'] = _conf['DATABASE_HOST']
else:
kwargs['host'] = _conf['DATABASE_HOST']
if _conf['DATABASE_PORT']:
kwargs['port'] = int(_conf['DATABASE_PORT'])
if hasattr(instance, 'options'):
kwargs.update(instance.options)
instance.connection = Database.connect(**kwargs)
cursor = instance.connection.cursor()
if instance.connection.get_server_info() >= '4.1':
cursor.execute("SET NAMES 'utf8'")
#if settings.DEBUG:
#return util.CursorDebugWrapper(MysqlDebugWrapper(cursor),
instance)
return cursor
instance.cursor = cursor
return
Function takes as argument hash with connection params.
