测试Django Inline ModelForms：如何安排POST数据？

Question

我有一个Django的'添加业务'视图，它增加了一个新的业务，内嵌'business_contact'表单。

形式工作正常，但我不知道怎么写了单元测试 - 具体而言，“POSTDATA”发送给self.client.post（settings.BUSINESS_ADD_URL，POSTDATA）

我已经检查我的浏览器中的字段，并尝试添加具有相应名称的发布数据，但运行时仍出现'ManagementForm数据丢失或被篡改'错误。

任何人都知道如何发布内嵌数据的任何资源？

相关型号，如果有帮助，查看&表格。洛塔谢谢。

的问题是你有没有包含在您的数据管理形式。您需要包含form-TOTAL_FORMS（formset中的表单总数，默认值为2），form-INITIAL_FORMS（formset中的初始表单数，默认值为0）和form-MAX_NUM_FORMS（表单集中表单的最大数量，默认值为'' ）。

有关管理窗体的更多信息，请参阅Formset documentation。
