Djangoカスタムログイン検証バックグラウンド

メールアドレス/携帯番号/ニックネームの登録をサポートし、django 1.6.2テストに成功しました.1、models

# -*- encoding: utf-8 -*-
from django.db import models
from django.contrib.auth.models import AbstractUser

from common.thumbs import ImageWithThumbsField

class User(AbstractUser):
    avatar = ImageWithThumbsField(' ', max_length=200, blank=True, null=True, upload_to='avatar/%Y/%m/%d/%H/%M%S', sizes=((30, 30), (50, 50), (100, 100), (180, 180), ))
    mobile = models.CharField(max_length=100, null=True, blank=True, db_index=True)

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

 
3、settings.pyにカスタム検証バックグラウンドを追加する

AUTHENTICATION_BACKENDS = (
    'accounts.backends.LoginBackend',
)

 
4、ビューでカスタムバックグラウンド検証を使用する
