If user_data is validated_data, you can simply add kwarg 'context' to pass
an extra data.
serializer = UserSerializer(data=user_data, context={'device_id': device_id
})
Inside UserSerializer, you can get device_id by
self.context['device_id']
Or you can use built-in method get_serializer_context in viewset.
def get_serializer_context(self):
"""
default return is
{
'request': self.request,
'format': self.format_kwarg,
'view': self
}
"""
context = super(YourViewSet, self).get_serializer_context()
# You can add what you want
context['device_id'] = self.request.META.get('HTTP_DEVICEID', '')
if you override get_serializer_context, you must call serializer with
get_serializer because get_serializer contains get_serializer_context
method.
class YourViewSet(viewsets.GenericViewSet):
queryset = Foo.objects.all()
serializer_class = UserSerializer
...
def bar(self, request, *args, **kwargs)
...
*serializer **= self.get_serializer(data=user_data)*
Now, You can get context in serializer.
self.context['device_id']
# this also available because we pass request as context
self.context['request']['META']['HTTP_DEVICEID']
Hope this could help you :)
