Django queryset排除值
Django queryset exclude values

models.py

class ChatMessage(models.Model):
    ip=models.IPAddressField()
    message=models.CharField(max_length=200)

class BlockIp(models.Model):
    ip=models.IPAddressField()

admin.py

class ChatMessageAdmin(admin.ModelAdmin):
    def queryset(self, request):
        qs = super(ChatMessageAdmin, self).queryset(request)
        #block=BlockIp.objects.all()
        return qs.exclude(ip='1.1.1.1')

我已经为ChatMessage类重写了queryset方法。 我试图返回类似的东西：

SELECT * FROM chatmessage as v1 JOIN blockip as v2 on v1.ip!=v2.ip

所以用户只能看到ip不在blockip条目中的消息

return qs.exclude(ip=BlockIp.objects.all().ip)语法不正确:(

有什么建议？
