python object is not iterable (.objects.get(ID=id) 将对象序列化 )

在models.py中对象的class表中加入下列代码




class LicenceInfo(models.Model)
下面的代码放入到models 中 
def toJSON(self):
    fields = []
    for field in self._meta.fields:
        fields.append(field.name)

    d = {}
    for attr in fields:
        if isinstance(getattr(self, attr), datetime.datetime):
            d[attr] = getattr(self, attr).strftime('%Y-%m-%d %H:%M:%S')
        elif isinstance(getattr(self, attr), datetime.date):
            d[attr] = getattr(self, attr).strftime('%Y-%m-%d')
        else:
            d[attr] = getattr(self, attr)

    import json
    return json.dumps(d,ensure_ascii=False)#ensure_ascii=False的作用是中文输出是不会呈现\xxx\xx的字符、

使用:

print(obj.toJSON())
