Question

我想使用自定义模型扩展我的用户配置文件。不幸的是，每当我访问配置文件所在的页面时，我收到'tuple'对象没有属性'update'

我自己试图解决这个问题，但是经过2.5小时之后它确实让我感到困惑。

有人可以开导我吗？

型号：

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

# Create your models here.

class Skills(models.Model):
description = models.CharField(max_length=3000)

class UserProfile(models.Model):

#Choices
STAFF = (
    ('AD', 'Super User'),
    ('MA', 'Manager'),
)
DEPT = (
    ('TD', 'Tech Service'),
    ('CS', 'Customer Service'),
)
user = models.OneToOneField(User, blank=False, unique=True)
staff = models.CharField(max_length=2, choices=STAFF)
dept = models.CharField(max_length=3, choices=DEPT)
team = models.BooleanField(default=False)
skill = models.ManyToManyField(Skills)
email = models.EmailField()

User.profile = property(lambda u: UserProfile.objects.get_or_create(user=u)[0])

形式

from django import forms
from models import UserProfile

class UserProfileForm(forms.ModelForm):

class Meta:
    model = UserProfile
    fields = ('staff', 'dept', 'team', 'skill', 'email')

视图

from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect
from django.core.context_processors import csrf
from forms import UserProfileForm
from django.contrib.auth.decorators import login_required

@login_required
def user_profile(request):
if request.method == 'POST':
    form = UserProfileForm(request.POST, instance=request.user.profile)
    if form.is_valid():
        form.save()
        return HttpResponseRedirect('/accounts')
else:
    user = request.user
    profile = user.profile
    form = UserProfileForm(instance=profile)

args = ()
args.update(csrf(request))

args['form'] = form

return render_to_response(profile.html, args)

app urls.py

from django.conf.urls import patterns, include, url

urlpatterns = patterns('',
    url(r'^profile/$', 'userprofile.views.user_profile'),
    )

和标准urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
# Examples:
# url(r'^$', 'tms_core.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),

url(r'^admin/', include(admin.site.urls)),
url(r'^accounts/', include('userprofile.urls')),
)

最后回溯：

Environment:


Request Method: GET

另外，我正在虚拟环境中运行这个项目。

任何帮助都将不胜感激。

Answer 1

在您看来args应该是dict not tuple：

# args = ()
args = {}

Answer 2

在您的视图中，代码从元组更改为dict：

args = ()

为：

args = {}

Answer 3

我不确定你要做什么，但问题是：

args = ()   # This makes args into an empty tupple
args.update(csrf(request)) # This tries to invoke a missing update method

args['form'] = form # This looks like args should be a dictionary

尝试：

args = {}   # This makes args into an empty dictionary
args.update(csrf(request)) # This tries to invoke a update which a dict has

args['form'] = form

'tuple'对象没有属性'update'
