Django模型自定義序列化為JSON

Question

默認序列化器實現：

class Serializer(base.Serializer):
    """
    Serializes a QuerySet to basic Python objects.
    """

    internal_use_only = True

    def start_serialization(self):
        self._current = None
        self.objects = []

    def end_serialization(self):
        pass

    def start_object(self, obj):
        self._current = {}

    def end_object(self, obj):
        self.objects.append({
            "model"  : smart_unicode(obj._meta),
            "pk"     : smart_unicode(obj._get_pk_val(), strings_only=True),
            "fields" : self._current
        })
        self._current = None

數據輸出格式：

[{“ pk”：2，“ model”：“ android.job”，“ fields”：{“ status”：“ lol”，“ customer”：“ HAHA”}}，{“ pk”：3，“ model “：” android.job“，” fields“：{” status“：” lul“，” customer“：” BWAHA“}}]

我的首要任務：

class MySerialiser(Serializer):
    def start_serialization(self):
        self._current = None
        self.objects = []

    def end_serialization(self):
        pass

    def start_object(self, obj):
        self._current = {}

    def end_object(self, obj):
        self._current['id'] = obj._get_pk_val()
        self.objects.append(self._current)

輸出格式：

{“狀態”：“ lol”，“客戶”：“ HAHA”，id：2L} {“狀態”：“ lul”，“客戶”：“ BWAHA”，id：3L}

我需要的：

[{“狀態”：“大聲笑”，“客戶”：“ HAHA”，id：2L}，{“狀態”：“ lul”，“客戶”：“ BWAHA”，id：3L}]

注意-這是在Django中-所有這些都是String類型！ 不要以為它們是列表/字典

Answer 1

終於成功了！

class MySerialiser(Serializer):
    def start_serialization(self):
        self._current = None
        self.objects = []

    def end_serialization(self):
        simplejson.dump(self.objects, self.stream, cls=DjangoJSONEncoder, **self.options)

    def getvalue(self):
        if callable(getattr(self.stream, 'getvalue', None)):
            return self.stream.getvalue()

    def start_object(self, obj):
        self._current = {}

    def end_object(self, obj):
        self._current['id'] = obj._get_pk_val()
        self.objects.append(self._current)
        self._current = None
