编辑个人资料用户Django

Question

我正在尝试编辑配置文件，但出现此错误“ / blog / edit /中的DoesNotExist，用户匹配查询不存在。”

def Profil(request, username):
    if request.user.is_authenticated():
        base_template_name = 'blog/base.html'
    else:
        base_template_name = 'blog/visitor.html'
    user = User.objects.get(username=username)
    logged_in_user_posts = Post.objects.filter(user=user)
    context = {'base_template_name':base_template_name}
    return render(request, 'blog/profil.html', {'user':user, 'posts':logged_in_user_posts})



def update_profile(request):
    if request.method == 'POST':
        profile_form = ProfileForm(request.POST, request.FILES, instance=request.user.profile)
        if profile_form.is_valid():
            profile_form.save()
            messages.success(request, ('Your profile was successfully updated!'))
            return redirect('blog:index')
        else:
            messages.error(request, ('Please correct the error below.'))
    else:
        profile_form = ProfileForm(instance=request.user.profile)
    return render(request, 'blog/edit_profile.html', {
        'profile_form': profile_form })

在urls.py中：

 url(r'^(?P<username>\w+)/$',  views.Profil, name = 'profil'),
url(r'^edit/$', views.update_profile, name='edit_profile'),

此错误来自user = User.objects.get(username=username)行。 get()函数仅给出1个匹配项，如果不存在任何匹配项，则会引发DoesNotExist错误。 要解决该问题，您将需要使用try-除外：

try:
  user = User.objects.get(username=username)
except User.DoesNotExist:
  # There is no such user, throw 404 or do anything else
