Django rest framework add dict to serializer

This is my serializers.py:

class SysUserSerializer(serializers.ModelSerializer):
    pk = serializers.IntegerField(read_only=True)
    login_id = serializers.CharField(required=False)
    name = serializers.CharField(required=False)

    class Meta:
        model = SysUser
        fields = ('pk','login_id','name')

This is my views.py:

class GetUserDetail(APIView):
    def get(self, request, format=None):
        sysuser = SysUser.objects.get(id=1)
        serializer = SysUserSerializer(sysuser)
        serializer.data['gender'] = 'male' # i don't think this line is working
        return Response(serializer.data, status=200)

But i get this response:

{"pk": 1, "login_id": "john77", "name": "John"}

I want the response like this:

{"pk": 1, "login_id": "john77", "name": "John", "gender": "male"}

How it can be done? is it possible to do so?

Problem here that serializer.data is not instance argument, but property which returns it. So you can fix this by assigning serializer.data to variable.

class GetUserDetail(APIView):
    def get(self, request, format=None):
        sysuser = SysUser.objects.get(id=1)
        serializer = SysUserSerializer(sysuser)
        data = serializer.data
        data['gender'] = 'male'
        return Response(data, status=200)

Also you can assign data to serializer.data in validate method of serializer
