我有一个页面显示用户及其关于。在那里,有一个链接来更新他们的关于。但是,当我打开该链接时,它会向我显示此错误:
DoesNotExist at /profile/user/update_about/
User matching query does not exist.
回溯突出显示此行,该行来自视图中的profile
方法:
13. user = User.objects.get(username=unquote(user_name))
但是,当我加载profile
方法时,不会发生此错误。它仅出现在视图中的update_profile
方法上。
views.py
from django.shortcuts import render
from django.http import HttpResponseRedirect
from urllib import unquote
from django.contrib.auth.models import User
from models import About
from forms import AboutForm
# Create your views here.
def profile(request, user_name):
user = User.objects.get(username=unquote(user_name))
about = About.objects.get_or_create(user=user)
about = about[0]
return render(request, 'user_profile.html', {
'user':user,
'about_user':about
})
def update_about(request, user_name):
user = User.objects.get(username=unquote(user_name))
if request.method == 'POST':
form = AboutForm(request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/')
else:
about = About.objects.get(user=user)
form = AboutForm(initial={'dob':about.dob})
return render(request, 'update_about.html',{
'form':form
})
urls.py
urlpatterns = patterns('',
# Examples:
url(r'(?P<user_name>[\w@%.]+)/$', 'user_related.views.profile', name='profile'),
url(r'(?P<user_name>[\w@%.]+)/update_about/$', 'user_related.views.update_about', name='update_about'),
造成这种情况的原因是什么?非常感谢您的帮助。谢谢。
答案 0 :(得分:1)
您忘记在正则表达式的第一个位置添加插入符号(^
)。因此,第一个正则表达式与URL的“update_about /”部分匹配。
固定代码:
url(r'^(?P<user_name>[\w@%.]+)/$', 'user_related.views.profile', name='profile'),
url(r'^(?P<user_name>[\w@%.]+)/update_about/$', 'user_related.views.update_about', name='update_about'),
