我現在將它與元類（而不是方法）一起使用，因為Django 1.3否則會顯示一些怪異之處。

class MyModelAdmin(admin.ModelAdmin):

    form = MyCustomForm

    def get_form(self, request, obj=None, **kwargs):

        ModelForm = super(MyModelAdmin, self).get_form(request, obj, **kwargs)

        class ModelFormMetaClass(ModelForm):

            def __new__(cls, *args, **kwargs):

                kwargs['request'] = request

                return ModelForm(*args, **kwargs)

        return ModelFormMetaClass

然后重寫MyCustomForm.__init__如下：

class MyCustomForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):

        self.request = kwargs.pop('request', None)

        super(MyCustomForm, self).__init__(*args, **kwargs)

然后，您可以使用ModelFormwith的任何方法訪問請求對象self.request。

值得一說的是，如果使用的是基于類的視圖，而不是基于函數的視圖，請get_form_kwargs在編輯視圖中覆蓋。自定義CreateView的示例代碼：

from braces.views import LoginRequiredMixin

class MyModelCreateView(LoginRequiredMixin, CreateView):

    template_name = 'example/create.html'

    model = MyModel

    form_class = MyModelForm

    success_message = "%(my_object)s added to your site."

    def get_form_kwargs(self):

        kw = super(MyModelCreateView, self).get_form_kwargs()

        kw['request'] = self.request # the trick!

        return kw

    def form_valid(self):

        # do something

上面的視圖代碼將request作為關鍵字的參數之一提供給表單的__init__構造函數。因此，在您ModelForm執行以下操作：

class MyModelForm(forms.ModelForm):

    class Meta:

        model = MyModel

    def __init__(self, *args, **kwargs):

        # important to "pop" added kwarg before call to parent's constructor

        self.request = kwargs.pop('request')

        super(MyModelForm, self).__init__(*args, **kwargs)
