Question

我有一个使用我的imagemodel的inlineformset。它有一个外键给我的住宿模型定义如下：

ImageFormset = inlineformset_factory(Lodging,ImageModel,fields=('image',),
can_delete=True,form=ImageForm,extra=0)

我可以从网址获取accommodation_id，并可以使用它来创建住宿实例。然后，我将它传递给我的ImageFormset实例

lodging=Lodging.objects.get(id=ad_id)
formset = ImageFormset(instance=lodging)

通过这种方式，我将得到一些初始形式。我的问题是我应该在单元测试中作为数据传递什么。到目前为止我尝试的是：

data = {
        'imagemodel_set-TOTAL_FORMS': 2,
        'imagemodel_set-INITIAL_FORMS': 2,
        'imagemodel_set-0-image': SimpleUploadedFile('test_image1.jpg',
                get_binary_data(self.image3_location),
                content_type='image/jpeg'),
        'imagemodel_set-1-image': SimpleUploadedFile('test_image2.jpg',
                get_binary_data(self.image4_location),
                content_type='image/jpeg'),
    }

但是这给了我错误：“['ManagementForm数据丢失或被篡改']” 任何帮助将不胜感激。

编辑：

测试代码

def test_lodging_edit_view_success(self):
    create_lodging(self)
    response = self.client.get(reverse('lodging:edit',args=[1]))
    data = {
        'imagemodel_set-TOTAL_FORMS': 2,
        'imagemodel_set-INITIAL_FORMS': 2,
        'imagemodel_set-0-image': SimpleUploadedFile('test_image1.jpg',
                get_binary_data(self.image3_location),
                content_type='image/jpeg'),
        'imagemodel_set-1-image': SimpleUploadedFile('test_image2.jpg',
                get_binary_data(self.image4_location),
                content_type='image/jpeg'),
        'rent': '4100',
        'update': 'any value'
    }
    response = self.client.post(reverse('lodging:edit',args=[1]),data)
