Continously running Celery Task in Django
I've a Django app which should constantly listen for messages from Kafka and then send them via WebSocket to client. Problem is how to setup constant listener. For future scalability we decided to bring Celery in project to manage these issues with scaling. My task actually look like: class ConsumerTask(Task): name = 'consume_messages' def run(self, *args, **kwargs): consumer = get_kafka_consumer(settings.KAFKA_URL, settings.FAULT_MESSAGES_KAFKA_TOPIC, 'consumer_messages_group') logger.info("Kafka's consumer has been started") while True: messages = consumer.poll() for _, messages in messages.items(): messages, messages_count = self.get_message(messages) if messages_count > 0: messages = save_to_db() send_via_websocket_messages(messages) It properly saves and sends messages via WS, but problems comes from infinite loop in task. For some reason (probably task timeout constraint) task pop out if queue and never runs again. I am not sure that daemonizing celery workers will solve this problem. Could you please provide some strategies now organize "Constantly running part" of this process? -
Difference between add() and create() functions and the functionsality of save() method
I have been trying to understand the difference between .add() and .create() functions through django documentation. As far as I have understood is that: add() function with Foreign Key just updates the model and with m2m relation it does the bulk creation which eventually doesn't call for any save method. create function will create the instance of the object and save it. My doubt is: What does actually save does? If only create an instance without saving it, what does it mean? What is the main difference between add() and create() functions? -
Passing model instance's id in Django modelformset_factory
I am using modelformset_factory to be able to edit one parameter for all instances of a model. It works but I would like to display in the template the id of each individual model instance.

Django(WAS) and Nginx running in same fargate task container - what proportion of cpu and mem allocation is recommended?
I have django and nginx containers running in same fargate task containers with 4GB mem and cpu_limit of 2048(=2vCPU). I currently have django use 75% of cpu and 3GB mem, and ngxin with 25% of cpu and 0.7GB mem (0.3mem left for task itself). But I have made this proportional decision on hitch, as I could not find any materials/guidelines on this topic. Any ideas or recommendations? Thanks. -

How to create an object of Foreign class key in python with filter?
I came across the problem of creating an object which doesn't exist. The models are as follows: class Contact(models.Model): name = models.CharField(max_length=255, blank=True) class Phone(models.Model): contact = models.ForeignKey(Contact,related_name='contact_number') number = models.CharField(max_length=255) Now, when I fire a query Contact.objects.filter(id=1031).values('contact_number') The Output is: <QuerySet [{'contact_number': None}]> Can there be any Query for creating the contact_number for the same when it is None? Because if I update Contact.objects.filter(id = 1031).update(contact_number = '9999999999') it gives me an error? Error: AttributeError: 'ManyToOneRel' object has no attribute 'get_db_prep_save' What can be the possible correct query for creating it? -

How to hide Django Admin from the public on Azure Kubernetes Service while keeping access via backdoor
I'm running a Django app on Azure Kubernetes Service and, for security purposes, would like to do the following: Completely block off the admin portal from the public (e.g. average Joe cannot reach mysite.com/admin) Allow access through some backdoor (e.g. a private network, jump host, etc.) One scenario would be to run two completely separate services: 1) the main API part of the app which is just the primary codebase with the admin disabled. This is served publicly. and 2) Private site behind some firewall which has admin enabled. Each could be on a different cluster with a different FQDN but all connect to the same datastore. This is definitely overkill - there must be a way to keep everything within the cluster. I'm think there might be a way to configure the Azure networking layer to block/allow traffic from specific IP ranges, and do it on a per-endpoint basis (e.g. mysite.com/admin versus mysite.com/api/1/test). Alternatively, maybe this is doable on a per-subdomain level (e.g. api.mysite.com/anything versus admin.mysite.com/anything). This might also be doable at the Kubernetes ingress layer but I can't figure out how. What is the easiest way to satisfy the 2 requirements? -

Dango bootstrap styling shows up fine on dev-box, not on production
I've got a Django site which uses the "django-machina" forum software, which in its latest incarnation apparently uses Bootstrap4 styling. After installing the package according to directions, it looks beautiful on my development box. But, when I deploy exactly the same software on production, Bootstrap obviously isn't running because nothing is properly styled. There are no 404's and no console messages. *(Yes, I remembered to run manage.py collectstatic ...) There are some stylesheets complaints from Firefox but they're identical in both cases. But ... the display is not! Can anyone suggest what I might do in order to solve this problem? I'm stumped! -
How to get list of all fields corresponding to a model saved in content type framework in django
I have this requirement in which I have to show two dropdown fields on Django admin page. The first field will be the dropdown of all the table names available in my project, and the second field will be a dropdown all the available fields of the table selected in 1st dropdown. The second field will be dynamic based on the selection of the first dropdown. I am planning to handle this by overriding change_form_template. Now, I can show the dropdown of table names by fetching them through content type Django model, But not able to fetch corresponding fields as content type model save the model name as a string. So is there any way not necessarily using Content-Type to achieve such a requirement? Any help around that will be highly appreciated. Thank you. -
Saving many-to-many fields from the excel file in Django
