python - django_auth_ldap 自定义 AUTH_USER_MODEL IntegrityError

我试图让 django_auth_ldap 与自定义用户模型一起工作。经过一番努力,我用一个模型创建了新的应用程序:

class MyUser(django.contrib.auth.models.AbstractUser):
uidNumber = models.IntegerField(unique=True)

在 settings.py 中我有:

AUTH_USER_MODEL = 'test_ldap.MyUser' 
AUTH_LDAP_ALWAYS_UPDATE_USER = False
AUTH_LDAP_USER_ATTR_MAP = {"first_name": "firstName", "last_name": "sn", "email": "mail", "uidNumber": "uidNumber"}
AUTH_LDAP_PROFILE_ATTR_MAP = {"home_directory": "homeDirectory", "uidNumber": "uidNumber"}
AUTH_LDAP_BIND_DN = ""
AUTH_LDAP_BIND_PASSWORD = ""
AUTH_LDAP_USER_SEARCH = LDAPSearch("ou=People,ou=Main,o=TECH",
ldap.SCOPE_SUBTREE, "(uid=%(user)s)")

作为登录页面:

urlpatterns += patterns('', 
url(r'^login/$', 'django.contrib.auth.views.login', {
'template_name': 'login.tmpl'
}),
(r'^logout/$', 'django.contrib.auth.views.logout', {'next_page': '/'}),
)

manage.py syncdb 成功。

登录后我有NOT NULL 约束失败:test_ldap_myuser.uidNumber。看起来 LDAP 后端正在尝试仅使用默认类 User 数据保存用户。

Exception Type: IntegrityError at /login/
Exception Value: NOT NULL constraint failed: test_ldap_myuser.uidNumber

所以我尝试使用 populate_user 信号,如文档中所述:

@receiver(django_auth_ldap.backend.populate_user)
def ldap_populate_user_receiver(sender, user=None, ldap_user=None, **kwargs):
print "Signal received"
# set uidNumber accordingly

(我把它放在models.py中)

但是这个函数没有输出(它根本没有被调用)。当我将用户模型改回默认 User 时,一切正常(并且出现信号输出 - 在这种情况下,当然不需要更改任何数据)。看起来像 django 试图将数据写入数据库(get_or_create_user())或其他东西?

我做错了什么?

最佳答案

我设法解决了这个问题。我使用了默认的 auth.User 并添加了带有指向它的 ForeignKey 的模型。在这个模型中,我将拥有我需要的额外属性。通过与 LDAP 后端进行某种同步(例如,在创建新用户的情况下),这应该可行。
