Python Django modelformset_工厂未保存到数据库

问题在于，当将输入插入表单时，Django modelformset_工厂不会保存到数据库中。在提交表单以进行处理之后，似乎只有else语句到达。很明显，问题出在views.py中的part，如果请求中有“name”，那么就做某事。建议如何解决，我们将不胜感激。多谢各位

姓名

需要在您的

请求中。POST

， 仔细检查模板并添加一个带有

name='name'

<input name='name' />

但是您已经从表单字段中排除了

名称

。所以POST数据从不包含

name

。我不希望这个字段显示给用户。无论如何，我试着把它包括进去，但Sitl并没有保存到数据库中。我认为问题在于，if request.method=='POST'和'name'在request.POST:中永远不会满足，因为'name'在POST中永远不存在。想知道在这种情况下，传递信息和区分不同形式的正确方法是什么？
