Django，使用ModelForm更新用户配置文件 [英] Django, updating a user profile with a ModelForm

问题描述

我正在为用户的配置文件显示一个简单的ModelForm，并允许用户对其进行更新。这里的问题是我的逻辑是有缺陷的，并且在成功的form.save（）调用之后，旧的值显示在页面上。直到刷新才显示适当的值。这里有什么问题？

I'm trying to display a simple ModelForm for a user's profile and allow the user to update it. The problem here is that my logic is somehow flawed, and after a successful form.save() call, the old values show on the page. It isn't until a refresh that the appropriate value is shown. What is wrong here?

@login_required
def user_profile(request):
    success = False
    user = User.objects.get(pk=request.user.id)
    upform = UserProfileForm(instance=user.get_profile())   

    if request.method == 'POST':
        userprofile = UserProfileForm(request.POST, instance=user.get_profile())
        if userprofile.is_valid():
            up = userprofile.save(commit=False)
            up.user = request.user
            up.save()
            success = True

    return render_to_response('profile/index.html',
        locals(), context_instance=RequestContext(request))

我只是想更新一个现有的配置文件，而不是添加一个新的。

I'm just looking to update an existing profile, not add a new one.

推荐答案

尝试这样：

@login_required
def user_profile(request):
    success = False
    user = User.objects.get(pk=request.user.id)
    if request.method == 'POST':
        upform = UserProfileForm(request.POST, instance=user.get_profile())
        if upform.is_valid():
            up = upform.save(commit=False)
            up.user = request.user
            up.save()
            success = True
    else:
        upform = UserProfileForm(instance=user.get_profile())       

    return render_to_response('profile/index.html',
        locals(), context_instance=RequestContext(request))
