what should i do to be able to post multiple contents in my code in django rest framework?-CodePudding

This is my serializers.py:

from rest_framework import serializers
from .models import product
 


class productSerializer(serializers.ModelSerializer):
    class Meta:
        model= product
        fields="__all__"

views.py:

from django.shortcuts import render
from .models import *
from rest_framework import viewsets
from .serializers import productSerializer
from rest_framework.parsers import JSONParser

class productviewset(viewsets.ModelViewSet):
    queryset=product.objects.all()
    serializer_class=productSerializer

When i want to post multiple contents like this:

[
  {
     "Number": 1,
     "name": "1005001697316642",
     "image": "https://",
     "description": "fffffffff",
     "price": "USD 23.43",
     "buy": "https://"
  },
  {
     "Number": 2,
     "name": "1005002480978025",
     "image": "https://",
     "description": "dffdfdddddddddddddd",
     "price": "USD 0.89",
     "buy": "https://"
   }
 ]

I get this error:

HTTP 400 Bad Request

Allow: GET, POST, HEAD, OPTIONS

Content-Type: application/json

Vary: Accept

{ "non_field_errors": [ "Invalid data. Expected a dictionary, but got list." ] }

what should i do to be able to post multiple contents?

CodePudding user response：

You have to overwrite the create method to allow multiple objects, So we will overwrite it in the scope of the class that inherits ModelViewSet, as shown below:

def create(self, request):
serialized = MovieTicketSerializer(data=request.data, many=True)
if serialized.is_valid():
    serialized.save()
    return Response(serialized.data, status=status.HTTP_201_CREATED)
return Response(serialized._errors, status=status.HTTP_400_BAD_REQUEST)
