我让它与exists()一起工作。

try:
    if MyModel.objects.filter(
        name = active_sheet["{}{}".format("A", row)].value,
    ).exists():
        # add data to list 
    else: 
        # save the new user into the user model
        MyModel.objects.create(
            name = active_sheet["{}{}".format("A", row)].value,
        )
except Exception as e:
    messages.warning(request, '%s. If you are seing this, there is an error in your file.' % e)
