我正在尝试按照 [Django Tutorial 6][1] 进行用户身份验证。但我卡住了。我收到此属性错误：unicode' 对象没有属性'get'。模型、视图和表格如下。不知道错误在哪里......需要一些帮助......
模型.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
视图.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.py
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
