「元組」對象沒有屬性「更新」

Question

我想使用自定義模型來擴展我的用戶配置文件。不幸的是，無論何時訪問配置文件所在的頁面，我都會收到'元組'對象沒有任何屬性'更新'

我試圖自己解決這個問題，但經過2,5小時後，米卡住了。

請問有誰能夠賜教嗎？

型號：

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') 

視圖

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) 

應用urls.py

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

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

和標準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')), 
) 

最後回溯：

Environment: 


Request Method: GET 
Request URL: http://127.0.0.1:8000/accounts/profile/

    20.  args.update(csrf(request)) 

Exception Type: AttributeError at /accounts/profile/

另外，我運行在一個虛擬的ENV這個項目。

任何幫助，將不勝感激。

Answer 1

在您看來args應字典不會元組：

# args =() 
args = {} 

Answer 2

在從一個元組的字典視圖代碼更改：

args =() 

到：

args = {} 

Answer 3

我我不確定你想要做什麼，但問題是：

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 

嘗試：

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
