如何在同一个模板中使用两个不同的Django表单？

My forms.py:

class AlertForm(forms.ModelForm):
class Meta:
    model=Alert
    fields = ('high','medium', 'user')
    widgets = {
        'user':  forms.HiddenInput()
    }

AlertCountFormset = modelformset_factory(Alert,
                                       form = AlertForm)
class AlertForm(forms.ModelForm)
