如何在序列化之後更新查詢中的json數據？

Question

我有一個模型有一個ForeignKey字段。

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) 

而在視圖上，我做了filter查詢。

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

並序列化。

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

正如我們現在，這裏的JSON看喜歡：

"[ 
{ 
    "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 
} 
]" 

這看起來並不酷，因爲它只是返回的clientid，我不能調用name和clientaddress。因此，如何更新，以便JSON來看起來像這樣：

"[ 
{ 
    "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 
} 
]" 

或者有另一種方式調用clientname和address模板？

非常感謝您的回答...
