你这样做是正确的,只要改变 __init__ 对此

class NewTicket(forms.ModelForm):

    def __init__(self,user, *args, **kwargs):
        super(NewTicket, self).__init__(*args, **kwargs)
        try:
            client_id = UserExtend.objects.values_list('client_id', flat=True).get(user=user)
            self.fields['business'].queryset=Business.objects.filter(client__id=client_id)
        except UserExtend.DoesNotExist:
            ### there is not userextend corresponding to this user, do what you want 
            pass


    class Meta:
        model=Ticket
        fields = ('subject','business')

另外,不要忘记将request.user传递到视图中的表单。
