我的模板上有一个表单和一个表单集。问题在于，表单集引发验证错误，声称管理表单“丢失或已被篡改”。
这是我的看法

为避免此错误，只需将您的表单集POST边界包装在try / except块中，如下所示。
from django.core.exceptions import ValidationError # add this to your imports if request.method == 'POST': try: delblogformset = delblog(request.POST) except ValidationError: delblogformset = None if delblogformset and delblogformset.is_valid(): delblogformset.save() return HttpResponseRedirect('/home')
您的POST请求blogform缺少您所需的’ManagementForm’隐藏输入，delblogformset因此会引发验证错误。我们包装在try / except块中，因为我们知道ifValidationError已引发，而POST是为您提供的，blogform而不是为您提供的delblogformset。
blogform
delblogformset
ValidationError
