[Djangoチュートリアル6][1]に従ってユーザー認証を行おうとしています。しかし、私は立ち往生しています。この属性エラーが発生します：unicode'オブジェクトに属性'get'がありません。モデル、ビュー、およびフォームを以下に示します。エラーがどこにあるのかわからない...助けが必要...
models.py
from django.db import models
from django.contrib.auth.models import User
class Drinker(models.Model):
user = models.OneToOneField(User)
birthday = models.DateField()
name = models.CharField(max_length=100)
def __unicode__(self):
return self.name
