            form_ownerset.instance.owner1 = owner1
            form_ownerset.instance.owner2 = owner2
            form_ownerset.instance.owner3 = owner3
            form_ownerset.instance.owner4 = owner4
            form_ownerset.instance.owner5 = owner5

完成以上所有操作后，请致电：

            form_ownerset.instance.save()

如果仍然不起作用，请先尝试保存表单，而不必访问实例，然后编辑并保存：

            instance = form_ownerset.save(commit=False)
            instance.owner2 = owner2
            instance.owner3 = owner3
            instance.owner4 = owner4
            instance.owner5 = owner5
            instance.save()

或者更清楚地说：

            ownerset = form_ownerset.save(commit=False)
            ownerset.owner1 = owner1
            ownerset.owner2 = owner2
            ownerset.owner3 = owner3
            ownerset.owner4 = owner4
            ownerset.owner5 = owner5
            ownerset.save()

            company = form_company.save(commit=False)
            company.ownerset = ownerset
            company.save()

问题在于我的OwnerSet功能。在forms.py中，我定义了我希望owner1_id是一个字段，但我从未将任何数据传递到该字段中，也从未真正使用过它。每当我尝试提交数据时，这会在命令终端中抛出一个validationError，这会擦除POST请求，因此没有数据发送到数据库。删除forms.py中的OwnerSet表单并将所有OwnerSet ID发送到views.py中的company解决了此问题，数据再次提交到我的数据库
