这就是我最终解决此问题的方式：
我错误地选择了字段的类型：正确的是ModelChoiceField：
class ArchiveForm(forms.ModelForm): class meta: model = Archive fields = ['tags', 'version', 'sharegp'] localized_fields = None labels = {'tags': 'Related Keywords'} user = None usergroups = None sharegp = forms.ModelChoiceField(label='Share with groups', queryset=usergroups) def __init__(self, user, *args, **kwargs): self.user = user self.usergroups = Group.objects.filter(user=self.user) super(ArchiveForm, self).__init__(*args, **kwargs) self.fields['sharegp'].queryset = self.usergroups
