I need to post like this product: {"product_id": 5,"product_name": "time"}, what fields are available in the product model it should be posted on this product field.

Can you please suggest me a way as i tried many ways as per my knowledge but it dosen't worked.

CodePudding user response：

you are using a tuple for fields, put a comma behind product in youre fields. If you use a list then dont use an end comma

fields = ('org_id', 'org_name', 'org_address', 'org_phone_number', 'org_mail_id','org_logo','org_code','product',)
        depth = 1

CodePudding user response：

Update your serializers to:

class Organisation_Serializers(serializers.ModelSerializer):
    class Meta:
        model = Organisation
        fields = ('org_id','org_name','org_address','org_phone_number','org_mail_id','org_logo','org_code','product',)

Update your views as:

class Organisation_Viewset(DestroyWithPayloadMixin,viewsets.ModelViewSet):
    renderer_classes = (CustomRenderer, )  #ModelViewSet Provides the list, create, retrieve, update, destroy actions.
    queryset=models.Organisation.objects.all()
    parser_classes = [MultiPartParser, FormParser]
    serializer_class=serializers.Organisation_Serializers


    def create(self, request, *args, **kwargs):
        data = request.data
        serializer = Organisation_Serializers(data)
        serializer.is_valid(raise_exceptions=True)
        serializer.save()
        return Response(serializer.data)

Now we can send the id as an array for the create api:

curl -XPOST \
     -H [authentication]
     http://localhost:8000/some/api/url
     -d '{"org_name": "hero", "product": [1,2]}'
