*之后的add（）参数必须是序列，而不是Result

Question

Models.py

class Result(models.Model):

            host = models.CharField(max_length=200)
            type = models.CharField(max_length=1, choices=TYPE_CHOICES)
            active = models.BooleanField(default=False)
            current = models.FloatField()
            value = models.FloatField()
            notify = models.BooleanField(default=False)
            info = models.TextField()
            test = models.ForeignKey('test', related_name='result')
            group = models.ForeignKey(Group, blank=True, null=True, default=None, related_name='result')
            timestamp = models.DateTimeField()
            created = models.DateTimeField(auto_now=True)

我的资源：

class ResultResource(ModelResource):
        test = fields.ForeignKey(TestResource, 'test', full=True, related_name='result')
        group = fields.ForeignKey(GroupResource, 'group', full=True, related_name='result')

        class Meta:
            queryset = Result.objects.all()
            list_allowed_methods = ['get', 'post']
            resource_name = 'result'
            fields = ['host', 'type', 'current', 'value', 'notify', 'info', 'timestamp']
            include_resource_uri = False
            excludes = ['id', 'group']
            authentication = Authentication()
            authorization = Authorization()

我想通过帖子请求创建新资源。

这是我的JSON：

{
    "current": 26.74,
    "host": "host 1",
    "info": "info text",
    "notify": true,
    "test": "/api/v1/test/1/",
    "timestamp": "2010-11-10T03:07:43",
    "type": "w",
    "value": 10,
    "group" : "/api/v1/group/1/"
}

测试和小组存在。

但是我得到了这个错误：“error_message”：*之后的“add（）参数必须是序列，而不是结果”。

我读到tastypie在Many2Many字段中存在一些问题，因此我将Many2Many字段更改为Foreignkey字段。但它并没有解决问题。
