我已经为django 2实现了自定义用户设置。但是，我似乎找不到任何试图注册的错误源。
AttributeError at /register/
'AnonymousUser' object has no attribute '_meta'
出现此错误时，密码传递时没有散列，并且不保存到数据库，而其他值则传递良好。

答案 0 :(得分：1)
在注册中，您尝试使用关键字参数email进行身份验证，但是身份验证没有任何虚假的email，它需要username和password（除非您覆盖它）在自定义后端）。因此，请尝试这样（就像您的login_user视图一样）：
authenticate(request, username=email, password=password)
有关更多详细信息，请参见documentation。
您的密码也不会以哈希格式保存，因为您是使用save方法将密码直接保存到数据库而没有使用set_password。您需要以Registration格式更新save方法（就像您的UserAdminCreationForm一样）
def save(self, commit=True):
# Save the provided password in hashed format
user = super(UserAdminCreationForm, self).save(commit=False)
user.set_password(self.cleaned_data["password1"])
if commit:
user.save()
return user
