How to access the Data of an model using particular id in django rest framework

Question

I want to access the data of an model which is named as IssueReport by using it's ID in django rest framework so I used the post method for passing the ID manually to get the IssueReport data by that ID but it gives me the Error as,

This is my views.py,

class GetIssueReportById(generics.GenericAPIView):

    serializer_class=GetIssueReportSerializer
    def post(self,request,*args,**kwargs):
        serializer=self.get_serializer(data=request.data)
        if serializer.is_valid(raise_exception=True):
            id=serializer.data.get('id')
            report=IssueReport.objects.get(pk=id)
            data=IssueReportSerializer(report,context=self.get_serializer_context()).data
            return Response({
                'message':"Data Fetched successfully",
                'status':"success",
                'data':data,
                },status=status.HTTP_200_OK)
        else:
            return Response({
                'message':"Data not fetched",
                'status':status.HTTP_400_BAD_REQUEST
                })

this is my serializers.py,

class IssueReportSerializer(serializers.ModelSerializer):
    class Meta:
        model=IssueReport
        fields='__all__'

class GetIssueReportSerializer(serializers.ModelSerializer):
    class Meta:
        model=IssueReport
        fields=('id',)

So can someone help me out to access the data by using ID only or any other way, Thank you in advance.

Answer 1

You obviously sent GET request to your server, but in class GetIssueReportById(generics.GenericAPIView): you declared only post method.

Either define def get(): method in class GetIssueReportById , or send POST request to the server (may be with some REST client from browser plugin or VS Code plugin). If you get id argument with id=serializer.data.get('id') , id field must be in POST body.
