Django Rest Framework: Multiple post


Card image cap

I need to have a massive put in my rest endpoint and Django Rest Framework doesn’t do it. So I make my personal method for mycase.

Setup fo the project

You need to follow the tutorial from the official documentation of Django Rest Framework.

After this you have a MyModel, MyModelSerializer and a view class MyModelListPost.

Why I can’t use the default?

After you did the tutorial you have a base for a standard Django Rest Framework. This mean that you have only a get massive not an update massive. So we make one from scratch.

The CODE

This is the code for massive put. You need to map your classes and your fields for make this code working

 
# Code from https://fundor333.com

from rest_framework.response import Response 
from rest_framework.views i_port APIView 
from rest.models import MyModel_ 
from rest_framework import generics
from rest.serializer import MyModelSerializer

class MyModelListPost(generics.GenericAPIView, APIView): 
    queryset = MyModel.objects.all() 
    serializer_class = MyModelSerializer

    def put(self, request, *args, **kwargs):
        output = []
        for data in request.data:
            try:
                instance = MyModel.objects.get(unique_id=data["unique_id"])
                created = False
            except Exception:
                instance = MyModel.objects.create(
                    field1=data["field1"],
                    field2=data["field2"],
                )
                created = True
    
            if created:
                serializer = self.get_serializer(data=data)
            else:
                serializer = self.get_serializer(instance, data=data)
            if serializer.is_valid():
                serializer.save()
                output.append(serializer.data)
            else:
                output.append(serializer._errors)
        return Response(output, status=status.HTTP_200_OK)

In this case we use the unique_id to find any instance and update one by one with the get method. I know it’s not very Python Way but if you have some better solution please write below. Thanks
