Before my product model doesnt include variants. Now I have added variants which is ManytoMany relationships with Product model.

Override method of a django builtin Class
Just for example, I need to modify the implementation of AdminSite.get_app_list like following From #app['models'].sort(key=lambda x: x['name']) To app['models'] = sort_with_name_length(app['models']) //my own method Expected/desired approach: I supposed that it should be achievable by just writing following code in any of my custom module's models.py or sites.py file class MyAdminSite(AdminSite): def get_app_list(self, request): app_list = super().get_app_list(request) for app in app_list: #app['models'].sort(key=lambda x: x['name']) app['models'] = sort_with_name_length(app['models']) #an example change I need return app_list But what above code does is nothing, its never executed, until I use Monkey patching guided by this answer. What I could achieve from django.contrib.admin import AdminSite class MyAdminSite(AdminSite): def get_app_list(self, request): # res = super(MyAdminSite, self).get_app_list(request) //gives following error # super(type, obj): obj must be an instance or subtype of type # So i have to rewrite complete method again in my module like following app_dict = self._build_app_dict(request) app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower()) for app in app_list: #app['models'].sort(key=lambda x: x['name']) app['models'] = sort_with_name_length(app['models']) return app_list AdminSite.get_app_list = MyAdminSite.get_app_list Problem being faced: Above does what I need in a totally undesired way.

I have a Django app in which we have a download button and on click, on that button, the file should be rendered to the browser. I have already tried using the download_file method but the issue is the file is downloaded to the local system. Here is how my current code looks like: def downloadObject(sourceBucket, key): content_type = 'application/x-zip' s3_temp = boto3.client('s3') file = s3_temp.get_object(Bucket=sourceBucket, Key=key) response = FileResponse(file, content_type=content_type, filename="{}".format(key)) response['Content-Disposition'] = 'attachment; filename="{}"'.format(key) return response
