解决方法:
要避免此错误,只需将您的formset POST绑定在try / except块中,就像这样.
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')
来自blogform的POST请求缺少delblogformset所需的“ManagementForm”隐藏输入,因此会抛出验证错误.我们包装了一个try / except块,因为我们知道如果引发了ValidationError,那么POST就是针对你的blogform而不是delblogformset.
