自定义一个用户很简单models.py

from django.db import models
from django.contrib.auth.models import (
    BaseUserManager, AbstractBaseUser
)

class MyUserManager(BaseUserManager):
    def create_user(self, email, date_of_birth, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError("Users must have an email address")

        user = self.model(
            email=self.normalize_email(email),
            date_of_birth=date_of_birth,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, date_of_birth, password):
        """
        Creates and saves a superuser with the given email, date of
        birth and password.
        """
        user = self.create_user(
            email,
            password=password,
            date_of_birth=date_of_birth,
        )
        user.is_admin = True
        user.save(using=self._db)
        return user
               
class MyUser(AbstractBaseUser):
    email = models.EmailField(
        verbose_name="email address",
        max_length=255,
        unique=True,
    )
    date_of_birth = models.DateField()
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = MyUserManager()

    USERNAME_FIELD = "email"
    REQUIRED_FIELDS = ["date_of_birth"]

    def get_full_name(self):
        # The user is identified by their email address
        return self.email

    def get_short_name(self):
        # The user is identified by their email address
        return self.email

    def __str__(self):              # __unicode__ on Python 2
        return self.email

    def has_perm(self, perm, obj=None):
        "Does the user have a specific permission?"
        # Simplest possible answer: Yes, always
        return True

    def has_module_perms(self, app_label):
        "Does the user have permissions to view the app `app_label`?"
        # Simplest possible answer: Yes, always
        return True

    @property
    def is_staff(self):
        "Is the user a member of staff?"
        # Simplest possible answer: All admins are staff
        return self.is_admin

然后是admin.py

class UserAdmin(BaseUserAdmin):
    # The forms to add and change user instances
    form = UserChangeForm
    add_form = UserCreationForm

    # The fields to be used in displaying the User model.
    # These override the definitions on the base UserAdmin
    # that reference specific fields on auth.User.
    list_display = ("email", "date_of_birth", "is_admin")
    list_filter = ("is_admin",)
    fieldsets = (
        (None, {"fields": ("email", "password")}),
        ("Personal info", {"fields": ("date_of_birth",)}),
        ("Permissions", {"fields": ("is_admin",)}),
    )
    # add_fieldsets is not a standard ModelAdmin attribute. UserAdmin
    # overrides get_fieldsets to use this attribute when creating a user.
    add_fieldsets = (
        (None, {
            "classes": ("wide",),
            "fields": ("email", "date_of_birth", "password1", "password2")}
        ),
    )
    search_fields = ("email",)
    ordering = ("email",)
    filter_horizontal = ()

# Now register the new UserAdmin...
admin.site.register(MyUser, UserAdmin)
# ... and, since we"re not using Django"s built-in permissions,
# unregister the Group model from admin.
admin.site.unregister(Group)

最后是settings.py

AUTH_USER_MODEL = "customauth.MyUser"
AUTHENTICATION_BACKENDS = (
    "accounts.backends.LoginBackend",
)

这样一个自定义的用户模型就弄好了,接下来是自定义登录字段

class LoginBackend(object):
    def authenticate(self, username=None, password=None):
        if username:
            #email
            if re.match("^.+@([?)[a-zA-Z0-9-.]+.([a-zA-Z]{2,3}|[0-9]{1,3})(]?)$", username) != None:
                try:
                    user = User.objects.get(email=username)
                    if user.check_password(password):
                        return user
                except User.DoesNotExist:
                    return None
            #mobile
            elif len(username)==11 and re.match("^(1[3458]d{9})$", username) != None:
                try:
                    user = User.objects.get(mobile=username)
                    if user.check_password(password):
                        return user
                except User.DoesNotExist:
                    return None  
            #nick
            else:
                try:
                    user = User.objects.get(username=username)
                    if user.check_password(password):
                        return user
                except User.DoesNotExist:
                    return None                
        else:
            return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None
