如何在序列化后从查询中更新json数据?

I have a model which have a ForeignKey field.

我有一个模型，它有一个外国人的领域。

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)

And on views, I do a filter query.

在视图上，我做一个过滤器查询。

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

And serializing.

和序列化。

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

As we now, here's the json look likes:

现在，json看起来是这样的:

"[
{
    "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
}
]"

It's looks not cool because it just return id of client, I can't call the name and address of client. So how to update that json in order to looks like this:

它看起来不太酷，因为它只返回客户id，我不能调用客户的名字和地址。那么如何更新这个json呢?

"[
{
    "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
}
]"

Or there's another way to call name and address of client in template?

或者在模板中有另一种调用客户端名称和地址的方法?
