Django-如何在管理表单中设置请求?

我有一个使用请求对象的表单:

class FooForm(forms.ModelForm):

    class Meta:
        model = Foo
        fields = ('title', )

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop('request')
        super().__init__(*args, **kwargs)

在我看来,每当我想实例化表单时,只需执行以下操作即可:

class FooCreateView(LoginRequiredMixin, CreateView):
    model = Foo
    form_class = FooForm

    def get_form_kwargs(self):
        kwargs = super(FooCreateView, self).get_form_kwargs()
        kwargs.update({'request': self.request})
        return kwargs

class FooAdmin(admin.ModelAdmin):
    form = FooForm

但是轰!它死了:

KeyError at /admin/foo/foo/add/
'request'

我试着做下面的事情,但没有成功

def get_form(self, request, *args,  **kwargs):
    form = super(FooAdmin, self).get_form(request, *args, **kwargs)
    form.request = request
    kwargs['request'] = request
    return form
