Azure deployed django app not displaying media files on Vuejs frontend in prooduction
These are the packages that I am using Django==3.2 django-storages==1.12.3 I am trying to deploy a django REST API with Vuejs frontend on azure. This is my directory structure for the django API.

Django: 'Response' object has no attribute 'get' when using "del request.session['key']"
Hello I'm trying to practice my understanding of Django sessions and I ran into this error. what I'm trying to do is to save a counter to count how many times a user visited the (' ') route and display it on the Django template and then the key will be destroyed when visiting the route ('/destroy').

Long running Celery task result in mysql 104 Connection reset by peer
At my Django application, I use celery to process very long-running conversion tasks (video, audio and picture encoding). In general everything is working as expected, but sometimes a task takes really long time to complete (talking 6 hrs. Or more here). At the very end of each of these conversion tasks, an update operation is trigger against my database: Files.objects.filter(pk=files_obj).update(... And exactly this is the point where my celery task breaks with this message: django.db.utils.OperationalError: (2006, "MySQL server has gone away (ConnectionResetError(104, 'Connection reset by peer'))") The full trace can be found here: https://pastebin.com/qKB5KdpR Currently, my settings.py for Database connections looks like this: import pymysql pymysql.install_as_MySQLdb() ... # MySQL DATABASES = { 'default': { 'ENGINE': 'django_prometheus.db.backends.mysql', # 'ATOMIC_REQUESTS': True, 'STORAGE_ENGINE': 'InnoDB', 'CONN_MAX_AGE': 600, 'OPTIONS': { 'init_command': 'SET innodb_strict_mode=1', 'connect_timeout': 600, 'charset': 'utf8', }, 'NAME': env.str('MYSQL_DATABASE'), 'USER': env.str('MYSQL_USER'), 'PASSWORD': env.str('MYSQL_PASSWORD'), 'HOST': env.str('MYSQL_HOST'), 'PORT': env.str('MYSQL_PORT'), } } DEFAULT_AUTO_FIELD = 'django.db.models.AutoField' ... Enlarging CONN_MAX_AGE or connect_timeout does not make much sense to me here as tasks that are running for just 3 or 4 hrs. Are processed fine without this behavior. Currently, my guess is that this behavior is pymysql specific. Is there maybe a default timeout? Thanks in advance. -

What's the most efficient way to retrieve django queryset with the hightest number of posts for a related name?
I'm currently working on a website where advertisements will be posted to display vehicles for sale and rent. I would like to retrieve a queryset that highlights only one car brand (i.e. Audi) which has the highest number of posts for the respective model. Example: Displaying the Audi brand because it has the highest number of related posts. My question is, what's the most efficient way of doing this? I've done some work here but I'm pretty sure this is not the most efficient way. What I have is the following: # Algorithm that is currently retrieving the name of the brand and the number of related posts it has. def top_brand_ads(): queryset = Advertisement.objects.filter(status__iexact="Published", owner__payment_made="True").order_by('-publish', 'name') result = {} for ad in queryset: # Try to update an existing key-value pair try: count = result[ad.brand.name.title()] result[ad.brand.name.title()] = count + 1 except KeyError: # If the key doesn't exist then create it result[ad.brand.name.title()] = 1 # Getting the brand with the highest number of posts from the result dictionary top_brand = max(result, key=lambda x: result[x]) # Returns for i.e. (Mercedes Benz) context = { top_brand: result[top_brand] # Retrieving the value for the top_brand from the result dict. } print(context) # … -

My app relies on the js files (jQuery) for all interactions (API calls - for Ajax).

How to cache django rest framework (retrieve) with persistent cache
I have the following Django REST view: class AnnotationViewSet( mixins.CreateModelMixin, mixins.ListModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet ): queryset = Annotation.objects.all() serializer_class = AnnotationSerializer Accessing a single method will call the retrieve function thanks to mixins.RetrieveModelMixin. I would like to speed up the function since it requires multiple queries and it uses a lot of CPU. In particular: I'd like a persistent cache that could be used after restarting the application The cached data needs to be different based on the record retrieved (e.g. http://127.0.0.1/annotations/1 vs http://127.0.0.1/annotations/2, etc) As of now I tried to overwrite the view retrieve method: @method_decorator(cache_page(60 * 60 * 24 * 365)) def retrieve(self, request, *args, **kwargs): instance = self.get_object() serializer = self.get_serializer(instance) return Response(serializer.data) and to set the default cache to disk: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.filebased.FileBasedCache', 'LOCATION': '/home/django_cache', } } I don't think it is working, as I need to cache about 2 million items (I have about 2 millions records): the folder /home/django_cache uses less than a Mb and it's size changes every time I call the API. -

Is there anything else I can do to ensure that the unique_together field can be used? -
