Question

我正在尝试在django中制作用户注册表我浏览了许多链接，但我仍然感到困惑。我正在制作一些基石错误，请指出。这是我的代码：

models.py

from django.db import models
from django.db.models.signals import post_save
from django.contrib.auth.models import User

class UserProfile(models.Model):

    mobile = models.CharField(max_length = 20, null=False)
    address = models.CharField(max_length = 200)
    user = models.OneToOneField(User, unique=True)


def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

post_save.connect(create_user_profile, sender=User)

forms.py

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class CustomerRegistrationForm(UserCreationForm):
    mobile = forms.CharField(max_length = 20)
    address = forms.CharField(max_length = 200)

    class Meta:
        model = User
        fields = ('username','email','mobile','address','password1','password2')

view.py

from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from django.template import RequestContext
from django.core.context_processors import csrf
from neededform.forms import CustomerRegistrationForm

def register(request):
    print "I am in register function"   

    if request.method == 'POST':
        if request.method == 'POST':
            form = CustomerRegistrationForm(request.POST)
            if form.is_valid():
                f = form.save()
            return HttpResponseRedirect('/registered/')
    else:
        args = {}
        args.update(csrf(request))
        args['form'] = CustomerRegistrationForm()
    return render_to_response('User_Registration.html', args ,context_instance = RequestContext(request))

我在想的是，当我在views.py中执行form.save()时，django应该在auth_user表中创建用户并且必须插入值（即移动 UserProfile表中还有地址）。
但是发生的事情是它正在auth_user表中正确插入数据但在UserProfile表中只填充id和user_id颜色，mobile和address仍然是空的。
我究竟做错了什么？还有什么必须做的？谢谢。

看看以下内容：

def create_user_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

您创建的UserProfile对象仅设置了user属性！

我不认为使用signal是解决问题的最佳方法，因为将mobile和address从表单传递到配置文件创建点并不容易。相反，您可以覆盖首先保存用户的save() CustomerRegistrationForm方法，然后创建配置文件。像这样：

class CustomerRegistrationForm(UserCreationForm):
    # rest code ommited
    def save(self, commit=True):
        user = super(CustomerRegistrationForm, self).save()
        p = UserProfile.objects.get_or_create(user=user )
        p[0].mobile = self.cleaned_data['mobile']
        p[0].address = self.cleaned_data['address']
        p[0].save()
        return user

django字段中的自定义用户创建不存储值
