Question

因此，在此表单中，第一个字段保存＆amp;更新就好......但是当我想添加一个新对象时，它并没有那么好用。

#Views.py
def edit_auto(request):
car = Auto.objects.filter(user=request.user)
CarFormSet = modelformset_factory(Auto, form=AutoForm, max_num=3)

if request.method == 'POST':
    formset = CarFormSet(request.POST, request.FILES, queryset=car)
    if formset.is_valid():
        formset.save(commit=False)
        formset.user = request.user
        formset.save()

    return render_to_response('manage_users.html', {'message':'Success! The user has been updated!'}, context_instance=RequestContext(request))
else:
            formset = CarFormSet(queryset=car)
return render_to_response('mycar.html', locals(), context_instance=RequestContext(request))

#forms.py
class AutoForm(forms.ModelForm):
    class Meta:
        model = Auto
        user = Auto.user
        exclude = ('user',)

模板中有什么东西吗？如果它是表单的单个实例，form.user = request.user通常会保存，但事实并非如此。有什么建议？谢谢你的帮助。

对于用户分配步骤，只需遍历formset。

...
if request.method == 'POST':
    formset = CarFormSet(request.POST, request.FILES, queryset=car)
    if formset.is_valid():
        formset.save(commit=False)
        for form in formset:
            form.user = request.user
        formset.save()
...

Django Formset ...使用字段排除保存用户
