Elastic Beanstalk server using 97% memory warning
I just discovered that my Elastic Beanstalk server has health status with a warning "97% of memory is in use". Because of this I can not deploy updates or ssh and run the django shell.

Django - how to automatically create a new model instance when another model instance is created
I have an Order and Notification Model, whenever there is a new order model instance, i want to immediately create a notification for the new order, i wrote some functions in the models but when there is a new order, the notification instance does not get created. i still think there should be a better way to do this, how can i go about this? models.py class Orders(models.Model): service = models.ForeignKey(Service, on_delete=models.SET_NULL, null=True, related_name="service_orders") seller = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, related_name="seller") def create_notification(self): create_notification = Notification.objects.create(provider=self.seller, service=self.service, order=self , notification_type='new_order') create_notification.save() return create_notification class Notification(models.Model): provider = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, related_name="provider_notifications") service = models.ForeignKey(Service, on_delete=models.SET_NULL, null=True, related_name="service_notifications") order = models.ForeignKey(Orders, on_delete=models.SET_NULL, null=True, related_name="service_order") notification_type = models.CharField(max_length=100, choices=NOTIFICATION_TYPE, default="none") -
Django "DATABASES is improperly configured" error after updating versions
I am trying to update a few-year old existing django project to current django and python 3. We're running into a multitude of issues, but most haven't been to hard to identify and resolve. Currently we are running into the dreaded django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. error when trying to manage.py migrate or some other commands like inspectdb. The odd thing is that we definitely are defining the database config with a default db and engine. This setup below is from our settings.py file. It's set up that way just so that we could use sqlite for testing purposes or mysql like the live servers. I've tried both, and it doesn't work with either. I have put print statements in to confirm that it does hit the appropriate sections. I also tried the dummy engine just to test and that had the same issue. #LOCALDEV_DB = 'MYSQL' LOCALDEV_DB = 'SQLITE' if LOCALDEV_DB == 'MYSQL': DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'foo', 'USER': 'root', 'PASSWORD': '123456789', 'OPTIONS': { 'init_command' : 'SET default_storage_engine=MYISAM', }, #'STORAGE_ENGINE': 'MYISAM' } } elif LOCALDEV_DB == 'SQLITE': DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } The … -
Django CMS page tree default language
It seems I don't understand how to set the default language for Django CMS. I want the default language to be set to Dutch. However, for an unknown reason, it always defaults to English when creating or after modifying/editing a Page. Take the following scenario. I open the Page tree. English is selected. I select Dutch. It I edit this page. I publish it. I refresh the page, I click on edit, it opens the English page which is empty. Note: All cookies were removed as suggested in the documentation.

Django: Is possible use _set into the filter() method?
I'm working on my ListView called IndexView on my polls app. This view currently return the last five published questions (not including those set to be published in the future).

In Django, when trying to access a model's 1:1 relation that doesn't exist, sometime that relation is None, and sometimes it raises an exception. Why?
I noticed while debugging a Django application that with two tables with a 1:1 relation, trying to access the related object from the table that defines the 1:1 relation would return None, while trying to access the same nonexistent relation from the table that does not define the relation Django will raise a Model1.model2.RelatedObjectDoesNotExist exception. I was confused by this behavior as the same action has two different results on objects on the same type of relation. This is an example of the models used: class RelatedModel(models.Model): pass class RelationshipDefiner(models.Model): related_object = models.OneToOneField( RelatedModel, on_delete=models.CASCADE, related_name="relationship_definer", blank=True, null=True ) This is an example of trying to print the relations to screen: relationship_definer = RelationshipDefiner.objects.create() related_object = RelatedModel.objects.create() print("RELATIONSHIP DEFINER'S RELATED OBJECT:") print(relationship_definer.related_object) print("RELATED OBJECT'S RELATIONSHIP DEFINER:") print(related_object.relationship_definer) And the output: RELATIONSHIP DEFINER'S RELATED OBJECT: None RELATED OBJECT'S RELATIONSHIP DEFINER: Internal Server Error: /test/ File "/django/app/views/test.py", line 17, in test print(related_object.relationship_definer) app.models.sample.RelatedModel.relationship_definer.RelatedObjectDoesNotExist: RelatedModel has no relationship_definer. Why do 1:1 nullable relationships behave differently on either side of the relation, and is there a way to coerce Django to behave consistently across both sides of the relationship? -
Styling a GeoDjango widget with TailwindCSS
I have been trying to style the GeoDjango OSMWidget (for Polygon drawing) for ages but can't work out how to make it flexible. Setting the map width and map height is all fine for a fixed page size but what happens if someone snaps their browser window to half-screen? A fixed map width does not react to these changes and becomes an unwieldily feature so fast it's painful. Here is what the GeoDjango documentation suggests for widget styling: widgets = { 'geometry': forms.OSMWidget(attrs={ 'map_width': 1000, 'map_height': 400, 'default_zoom': 7.5 }), } Other widgets, such as forms.Select have the option for a style attribute where custom css can be defined. The map widgets ignore this completely. How can I force this map widget to respond to my css demands? I want flexible widgets, goddamit! *Bonus points for integration with tailwind -

How to indicate required fields on initial form render, using Bootstrap 5 styling and Django?
I am using Django 4.1 and Bootstrap 5. I think I'd like to mark required fields in a form as required, or maybe optional fields as optional, as suggested in this question. Django/Bootstrap already styles fields as green/red after form submission, if a required field is missing, but my request is when the form is first rendered. Could be with *s or with "(optional)" or whatever. What's the best way to do it? -

CSRF verification Failed in Firebase and Django integration
I am trying to integrate django and DRF with firebase real-time database and while creating a post request I ran into a CSRF verification error. CSRF verification failed. Request aborted. Some solutions I found online said that I should use render but I am actually using Django Rest Framework and would like to use something that works with JsonResponse and Serializers. Here's a test code. def post(self, request): """Function to handle post requests Args: request (_type_): _description_ """ # Get the data to be posted from the request name = request.POST.get('name') age = request.POST.get('age') location = request.POST.get('location') # Set the reference to the database ref = db.reference('/user1') # Push the data to the database ref.push({ 'Name': name, 'Age': age, 'Location': location }) Let me know if I should share how I am creating my firebase client, although I don't think that would be necessary. In conclusion, I would like to find a way to add a csrf_token to a post request method in Django and DRF. Another solution I saw used csrf_exempt but I don't want to use that either as that is not ideal. I do plan on taking this to production at some point so do recommend solutions … -

Docker-Compose Network Issue on Ubuntu 22.04 LTS
I've been developing my python application using Django with PostgreSQL and Nginx and Docker, driven by Docker-Compose on my Macbook M1. And recently, decided to deploy it on the remote server, which has Ubuntu 22.04 LTS, but encountered really weird issue. My web application says, that it cannot resolve host postgresql (service at docker-compose file, which you can find down below), however, it works fine on my machine, can it be related to the Docker? It might be because I installed imcompatible versions of Docker and Docker-compose on this remote server or apparently used wrong commands, but not really sure about that, as I haven't gained enough experience of working with Ubuntu yet. My Macbook's M1 Docker & Docker-compose Versions: ~ Docker - 20.10.12 ~ Docker-Compose - 1.29.2 My Remote's Server Ubuntu Docker & Docker-compose Versions: ~ Docker - 20.10.23 ~ Docker-compose - 1.29.2 My docker-compose.yaml file version: "3.9" services: nginx_server: container_name: "nginx_web_server" image: crazycoderrr/vdnh_nginx_server:latest # образ nginx для нашего проекта ports: - "8010:80" depends_on: - application_service volumes: - ./nginx/nginx.conf:/etc/nginx/nginx.conf networks: - private_network application_service: container_name: "application_server" image: crazycoderrr/vdnh_application:latest # образ backend сервиса нашего приложения ports: - "8000:8000" depends_on: - postgresql env_file: ./env/application.env networks: - private_network postgresql: container_name: "postgresql_database" image: crazycoderrr/vdnh_postgres_db:latest … -
How to override the autocomplete view for a specific model field in the Django admin?
I need to override the way a Select2 widget of a particular ForeignKey is behaving in the Django (4.1) admin. Namely, I am trying to increase the number of objects returned by the AJAX requests and defined by paginate_by in AutocompleteJsonView. Sadly this great solution no longer works with Django 4. How can I extend AutocompleteJsonView and somehow tell Django to use my custom view?
