序列化后如何从查询中更新json数据？

Question

我有一个具有ForeignKey 字段的模型。

class Client(models.Model):
    # more fields
    name = models.CharField()
    address = models.TextField()

class FessapComment(models.Model):
    # more fields
    timestamp = models.DateTimeField(auto_now=True)
    client = models.ForeignKey(Client)

关于视图，我进行filter 查询。

comments = FessapComment.objects.filter(fessap_id=fessap_id)

并进行序列化。

json_data = serializers.serialize('json', comments)
return JsonResponse(json_data, safe=False)

就像我们现在一样，这是 json 的样子：

"[
{
    "fields": 
        {
            "timestamp": "2016-05-06T13:39:46.584Z",
            "client": "U2B3DBDC",
        },
    "model": "socmed.fessapcomment", 
    "pk": 1
},
{
    "fields": 
        {
            "timestamp": "2016-05-06T15:23:12.641Z",
            "client": "U26A6E19",
        },
    "model": "socmed.fessapcomment", 
    "pk": 2
}
]"

它看起来并不酷，因为它只返回client 的id，我不能调用client 的name 和address。那么如何更新该 json 以使其看起来像这样：

"[
{
    "fields": 
        {
            "timestamp": "2016-05-06T13:39:46.584Z",
            "client": 
                {
                    "id": "U2B3DBDC",
                    "name": "Herman James",
                    "address": "Uooepi St.",
                },
        },
    "model": "socmed.fessapcomment", 
    "pk": 1
},
{
    "fields": 
        {
            "timestamp": "2016-05-06T15:23:12.641Z",
            "client": 
                {
                    "id": "U26A6E19",
                    "name": "Jared",
                    "address": "Ter St.",
                },
        },
    "model": "socmed.fessapcomment", 
    "pk": 2
}
]"

或者还有其他方法可以在模板中调用client 的name 和address？

非常感谢您的回答...
