[ASK] Django REST Framework POST multiple object

gan,,, ada yg bisa django ga disini.? semoga aja ada
ane ada kasus nih,,,

kronologi :
ane buat sebuah api untuk input data,,, kurang lebih gini tampilannya

Spoiler for DRF Api:

oke,, sekarang ane jelasin codingan ane gan,, biar gampang mencernanya,,,

Spoiler for models.py:

Code:

from django.db import models

from jsonfield import JSONField



class RawData(models.Model):

 types = models.CharField(max_length=10, null=True, blank=True)

 time = models.DateTimeField(auto_now_add=True)

 data = JSONField(null=True, blank=True, max_length=2000)



class Temp(models.Model):

 types = models.CharField(max_length=100, null=True, blank=True)

 data = models.TextField(null=True, blank=True)

 time = models.DateTimeField(auto_now_add=True)

Spoiler for serializers.py:

Code:

from django.forms import widgets

from rest_framework import serializers

from read.models import RawData



class JSONSerializerField(serializers.Field):

 """ 

 Serializer for JSONField -- required to make field writable

 """

 def to_internal_value(self, data):

 return data

 def to_representation(self, value):

 return value



class RawDataSerializer(serializers.ModelSerializer):

 data = JSONSerializerField()

 class Meta:

 model = RawData

 fields = ('id', 'types', 'data', 'time')

di serializer di atas ane pake JSONSerializerField biar bisa nampilin json di api nya nanti,

Code:

ane dapat script ini distackoverflow
soalnya kalo ga diginiin, nanti data yg masuk dianggap string...

lalu views.py nya kayak gini

Spoiler for views.py:

Code:

import json

from django.shortcuts import render

from read.models import RawData

from read.serializers import RawDataSerializer

from django.http import Http404

from rest_framework import generics

from rest_framework import filters



class RawDataList(generics.ListCreateAPIView):

 queryset = RawData.objects.all()

 serializer_class = RawDataSerializer()

 filter_backends = (filters.DjangoFilterBackend,)



class RawDataDetail(generics.RetrieveUpdateDestroyAPIView):

 queryset = RawData.objects.all()

 serializer_class = RawDataSerializer

lalu, kalo misalnya ane post single object, bisa masuk dg gampang
misal ane mau POST data JSON ini

Code:

{

 "types": "web",

 "data": {"data1": "data2", "data2": "data2", "data3": "data3"}

}

Hasil nya:

Spoiler for POST Single JSON:

lalu ane mau POST json list/array kaya gini

Code:

[{

 "data": {

 "data1": "1",

 "data2": "2"

 },

 "types": "VIN"

}, {

 "data": {

 "data1": "1",

 "data2": "2"

 },

 "types": "PPS"

}, {

 "data": {

 "data1": "1",

 "data2": "2"

 },

 "types": "PCM"

}]

muncul error kayak gini setelah ane post multiple JSON

Code:

HTTP 400 Bad Request

Content-Type: application/json

Allow: GET, POST, HEAD, OPTIONS

Vary: Accept



{

 "non_field_errors": [

 "Invalid data. Expected a dictionary, but got list."

 ]

}

inti nya ini kan ga bisa POST jika data nya adalah LIST,,,

setelah mencari dimana2, baca di docs nya tp ga jelas,,,
Docs django : http://www.django-rest-framework.org...ltiple-objects
disitu dijelasin tambahlan atribut

Code:

many=True

, udah tak coba malah error,,,
emank nya harus ditaruh mana,, ane bingung,,,

lalu ada referensi lain di SO
http://stackoverflow.com/questions/1...rest-framework
dia pake List()
cuma aku ga ngerti naruh nya dimana

ini jg ada ref lain di SO
http://stackoverflow.com/questions/2...ray-of-objects
di override get_serializers, sekali lagi ane ga paham taruh mana

kalo yg ini,, udah ane coba, ga error, tp ga ngaruh apa2
http://stackoverflow.com/questions/1...rest-framework

tolongin saya gan,,, pliss,,,,
kalo kurang jelas ttg pertanyaan saya tanyakansaja,,
matur nuwun
