如何使用django在模板中显示默认值？

Question

我正在使用modelform来扩展用户的个人资料.我希望以前保存的数据在用户决定写入之前显示在表单中.如何在django模板中执行此操作？

模型

class UserProfile(models.Model):
    user = models.ForeignKey(User, primary_key=True)
    quote = models.CharField('About', max_length =  200, null=True, blank=True)
    website = models.URLField('Personal website/blog', null=True, blank=True)

class UserProfileForm(ModelForm):
    class Meta:
        model = UserProfile
        fields = ('quote', 'website')
        widgets = {
            'quote': Textarea(attrs={'cols': 18, 'rows': 7, 'style': "width: 300px;"}),
        }

视图

@login_required 
def user_profile(request):
    user = User.objects.get(pk=request.user.id)
    if request.method == 'POST':
        upform = UserProfileForm(request.POST)
        if upform.is_valid():
            up = upform.save(commit=False)
            up.user = request.user
            up.save()
            return HttpResponseRedirect('/accounts/profile')
    else:
        upform = UserProfileForm()
    return render_to_response('reserve/templates/edit_profile.html', locals(), context_instance=RequestContext(request))

模板

{{ upform.as_p}}

在实例化时传递instance=user.get_profile()给UserProfileForm它.
