django - unicode'对象在Django中没有属性 'get'

Question

我正在尝试按照[Django教程6] [1]进行用户身份验证。但是我被卡住了。我收到此属性错误:unicode对象没有属性“get”。型号， View 和表格如下。不确定错误在哪里...需要一些帮助...

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

views.py

from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from django.template import RequestContext
from drinker.forms import RegistrationForm
from django.contrib.auth.models import User
from drinker.models import Drinker


def DrinkerRegistration(request):
    if request.POST:
        form =RegistrationForm(request.POST)
        if form.is_valid():
            user = User.objects.create_user(username=form.cleaned_data['username'],email=form.cleaned_data['email'])
            password = form.cleaned_data['password']
            user.save()
            drinker=Drinker(user=user,name=form.cleaned_data['name'],birthday=form.cleaned_data['birthday'])
            drinker.save()
            return HttpResponseRedirect('/profile/')
        else:
            return render_to_response('register.html',{'form':form,},context_instance=RequestContext(request))
    else:
        form = RegistrationForm()
        return render_to_response('register.html',{'form':form,},context_instance=RequestContext(request))

表格

from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
from drinker.models import Drinker 

class RegistrationForm(ModelForm):
    username = forms.CharField(label=(u'User Name'))
    email = forms.EmailField(label =(u'Email Address'))
    password = forms.CharField(label =(u'Password'),widget=forms.PasswordInput(render_value=False))
    password1 = forms.CharField(label =(u'Verify Password'),widget=forms.PasswordInput(render_value=False))

    class Meta:
        model = Drinker
        exclude = ('user',)

    def clean_username(self):
        username = self.cleaned_data['username']
        try:
            User.objects.get(username=username)
        except User.DoesNotExist:
            return username
        raise forms.ValidationError("That username is already taken. Please select another")
    def clean(self):
        password = self.cleaned_data['password']
        password1= self.cleaned_data['password1']
        if password and password1 and password != password1:
            raise forms.ValidationError("The passwords did not match. Please try again")
        return password

Answer 1

您是从password方法而不是clean()返回self.cleaned_data的。
