Django当我使用基于类的视图时，如何在表单中传递request.user（当前登录的用户）？

我想传递request.user以使用ModelMultipleChoiceField以表单形式显示当前用户 . 我可以在这里找出我的问题https://stackoverflow.com/a/25184373/6568309 . 我修改了我的代码，如下所示 .

but I could get solution with only function based view. 好吧，我一直在使用基于类的视图，因为我可以使用通用视图，并且首先推荐它 . Is it way to pass request.user like below with class based view(to use FormView or ModelFormView)? Additionally, Is is normal to mix function based views and class based views to meet your need in Django?

先感谢您 .

forms.py

class CustomForm(forms.Form):
    username = forms.CharField(initial='testname',max_length=150)
    email = forms.EmailField()
    phone_number = forms.CharField(max_length=15)
    position = forms.CharField(max_length=15)
    uperall = forms.ModelMultipleChoiceField(queryset=None)

    def __init__(self, *args, **kwargs):
        user = kwargs.pop('user', None)
        super(CustomForm, self).__init__(*args, **kwargs)
        self.fields['uperall'].queryset = User.objects.filter(username=user.username)

urls.py

urlpatterns = [
    url(r'^$', UserList.as_view(), name='index'),
    url(r'^create/$', UserCreate.as_view(), name='create'),
    url(r'^test/$', TestView.as_view(), name='test'),
    url(r'^test1/$', views.ftestview, name='test1'),
]

views.py

def ftestview(request):
    if request.method == 'POST':

    form = CustomForm(request.POST, user=request.user)

    if form.is_valid():
        username = form.cleaned_data['username']
        email = form.cleaned_data['email']
        phone_number = form.cleaned_data['phone_number']
        position = form.cleaned_data['position']

        with transaction.atomic():
            user = User.objects.create(username=username,email=email)
            userinfo = UserInfo.objects.create(user=user,phone=phone_number,position=position)
            userinfo.save()
            user.save()

        return HttpResponseRedirect('/success')

else:
    form = CustomForm(user=request.user)

return render(request, 'manager/alltoall.html', { 'form': form })

根据levi的回答，感谢 . 我改变了我的代码，如下所示

views.py

class TestView(FormView):
    form_class = CustomForm
    template_name = 'manager/alltoall.html'

    def get_form_kwargs(self):
        user = self.request.user
        form_kwargs = super(TestView, self).get_form_kwargs()
        form_kwargs.update({'initial': {'uperall': User.objects.filter(username=user.username)}})
        return form_kwargs

    def form_valid(self, form):
        username = form.cleaned_data['username']
        email = form.cleaned_data['email']
        phone_number = form.cleaned_data['phone_number']
        position = form.cleaned_data['position']

        with transaction.atomic():
            user = User.objects.create(username=username,email=email)
            userinfo = UserInfo.objects.create(user=user,phone=phone_number,position=position)
            userinfo.save()
            user.save()

        return super(TestView, self).form_valid(form)

但我得到的错误如下 .
