if is not supported in Django?
I read from Django documentaion:
Django doesn’t currently provide any support for foreign key or many-to-many relationships spanning multiple databases.
So I have two databases DB_1 and DB_2
DB_1: All inserts and updates will go to the default database( DB_1 ).
DB_2 (read_only): All read queries will go to DB_2 database
I have this class:
class Task(models.Model):
person = models.OneToOneField(Person)
start_date = models.DateField(null=True)
end_date = models.DateField(null=True)
free_day = models.DateField(null=True)
text = models.CharField(max_length=100)
def __str__(self):
return '%s' % self.person
and I'm trying to create object by using shell
p = Person.objects.get(username='Herehere')
t = Task(person=p,text='blabla')
t.save()
But I got this error:
AttributeError: 'DatabaseWrapper' object has no attribute 'Database'
If I change
person = models.OneToOneField(Person)
to
person = models.OneToOneField(Person, primary_key)
I got
'DatabaseWrapper' object has no attribute 'operators'
My settings.py db configurations:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
},
'ldap': {
'ENGINE': 'ldapdb.backends.ldap',
'NAME': AUTH_LDAP_SERVER_URI,
'USER': AUTH_LDAP_BIND_DN,
'PASSWORD': AUTH_LDAP_BIND_PASSWORD,
},
}
DATABASE_ROUTERS = ['ldapdb.router.Router']
