带有反斜杠的 Json 序列化数据

Question

我正在使用 rest_framework.response 方法发送多个 django 模型的对象。但是，响应包含带引号的反斜杠。这是我的观点:

@api_view()
def myfunctions(request,id):
    responseData = {}
    userObject = TifUser.objects.filter(id=id)
    attendances = Attendance.objects.filter(User=userObject)
    leaves = Leave.objects.filter(User=userObject)
    odds = ODD.objects.filter(User=userObject)
    printjobs = PrintJob.objects.filter(User=userObject)
    issues = Issue.objects.filter(User=userObject)

    #serialize into json
    userObject = serializers.serialize("json", userObject)
    attendances = serializers.serialize("json",attendances)
    leaves = serializers.serialize("json",leaves)
    odds = serializers.serialize("json",odds)
    printjobs = serializers.serialize("json",printjobs)
    issues = serializers.serialize("json",issues)

    #set responseData dictionary values
    responseData['user'] = userObject
    responseData['attendances'] = attendances
    responseData['leaves'] = leaves
    responseData['odds'] = odds
    responseData['printjobs'] = printjobs
    responseData['issues'] = issues
    #responseData['attendances'] = userObject
    return response.Response(responseData)

我得到的 json 响应是:

{"attendances":"[{\"model\": \"mainApp.attendance\", \"pk\": 5, \"fields\": {\"ArrivalTime\": \"2016-06-27T18:45:46.355Z\", \"DepartureTime\": null, \"User\": 4, \"ArrivalImei\": \"1\", \"DepartureImei\": null, \"Hash\": \"321f059c-4230-417a-adff-f0035097c85d\"}}, {\"model\": \"mainApp.attendance\", \"pk\": 13, \"fields\": {\"ArrivalTime\": \"2016-07-18T15:40:39.943Z\", \"DepartureTime\": null, \"User\": 4, \"ArrivalImei\": \"2\", \"DepartureImei\": null, \"Hash\": \"e61fad3e-8238-46fc-b09b-8b7754d43f3b\"}}]","printjobs":"[{\"model\": \"mainApp.printjob\", \"pk\": 1, \"fields\": {\"User\": 4, \"DateAdded\": \"2016-07-18\", \"Status\": \"disapproved\", \"Person\": 5, \"Level\": \"boss\", \"Client\": \"someone\", \"HandledBy\": \"tester\", \"SanctionedBy\": \"myself\", \"AdvancePayment\": 0, \"FinalPayment\": 1000, \"PaymentNumber\": 1, \"Remarks\": \"something\"}}]","odds":"[]","user":"[{\"model\": \"mainApp.tifuser\", \"pk\": 4, \"fields\": {\"AuthUser\": 7, \"Head\": null, \"Boss\": null, \"ClrLevel\": 1, \"Department\": 1, \"DesignationName\": 1, \"Name\": \"tester\", \"IsRegistered\": true, \"DateOfBirth\": \"1222-11-11\", \"Anniversary\": \"2001-12-22\", \"Mobile\": \"2134567890\", \"gcmDevice\": null, \"FatherName\": \"\", \"MotherName\": \"\", \"PersonalEmail\": \"\", \"Gender\": \"Male\", \"CurrentAddress\": \"\", \"PermanentAddress\": \"\", \"PANNumber\": \"\", \"AadharCardNumber\": null, \"BloodGroup\": \"\", \"MaritalStatus\": \"Married\", \"ProfilePhoto\": \"\", \"Imei\": \"\"}}]","leaves":"[]","issues":"[]"}

有没有其他方法可以做到？我的理解是，它对数据进行了两次编码(一次在 serializers.serialize 中，然后在 response.Response 中)。但我不想那样。我想要嵌套对象。像这样的东西:

{"attendances":[{"model": "mainApp.attendance", "pk": 5, "fields": {"ArrivalTime": "2016-06-27T18:45:46.355Z", "DepartureTime": null, "User": 4, "ArrivalImei": "1",...

谁能告诉我如何实现这一目标？提前致谢。

我终于设法解决了它。问题是，当使用 serializer.serialize() 函数序列化对象时，我得到了一个字符串。而我想要一个字典。我不得不使用 json.loads() 将字符串转换为字典:

responseData['user'] = json.loads(userObject)

一切都如我所愿。现在，响应类似于:

{
    "attendances": [
        {
            "pk": 5,
            "model": "mainApp.attendance",
            "fields": {
                "DepartureTime": null,
                "Hash": "321f059c-4230-417a-adff-f0035097c85d",
                "ArrivalImei": "1",
                "DepartureImei": null,
                "User": 4,
                "ArrivalTime": "2016-06-27T18:45:46.355Z"
            }
        },
