# Django method decorator

Recently I found some interesting issue when switching from Django 4.x to Django 5.x. I’ve been working with a legacy software and I had found some interesting case when core framework (Django) has been updated to one of the latest versions.

In the [class view](https://docs.djangoproject.com/en/5.1/topics/class-based-views/) we can add lots of different decorators to methods. One of the main decorator I’ve been using for ling time in my django code was the one that I wrote to catch and log view calls, ie.

```python
def my_log(*args):
    def log_func(function):
        def wrapper(request, *args, **kwargs):
            # inject request API payload for airbrake
            if log.isEnabledFor(logging.DEBUG):
                function_name = "{}.{}".format(type(function).__name__, function.__name__)
                log.debug(
                    "{} called with data: {}, args:{}, kwargs:{}".format(function_name, request.data, args, kwargs)
                )
                responder = function(request, *args, **kwargs)
                try:
                    log.debug("{} responds with: {}".format(function_name, responder.content))
                except Exception as ex:
                    log.error("{} failed to log response: {}".format(function_name, ex))
                return responder
            else:
                return function(request, *args, **kwargs)
        return wrapper
    return log_func
```

Once I have custom decorator I can apply it to my view as shown in the following example.

```python
class MyRestAPIView(GenericAPIView):

    authentication_classes = ()
    authentication_classes = (authentication.TokenAuthentication,)
    permission_classes = (permissions.IsAuthenticated, )

    @my_log
    def post(self, request):
        """"magic happens here"""
        return Response(response.data, status=http_status.HTTP_201_CREATED)
```

That’s been working just fine until Django version 5. Once upgraded to this I realized that my decorator does not work anymore. The easiest fix is to move it under method decorator call like in proceeding example.

```python
from django.utils.decorators import method_decorator

class MyRestAPIView(GenericAPIView):

    @method_decorator((my_log())
    def post(self, request):
        """"magic happens here"""
        return Response(response.data, status=http_status.HTTP_201_CREATED)
```

That’s it! Happy coding:)
