ModelForm including ForeignKeys with multiple databases
Having two models in models.py such as: provider_name = models.TextField(primary_key=True, default=None) provider_address = models.TextField(null=False, blank=False, default=None) class PhoneNumber(models.Model): number = models.IntegerField(primary_key=True, default=None) provider = models.ForeignKey(PhoneProvider, on_delete=models.SET_NULL, default=None, null=False, blank=False) And then in forms.py I create two model forms: class Meta: model = PhoneProvider fields = "__all__" class FormPhoneNumber(forms.ModelForm): class Meta: model = PhoneNumber fields = "__all__" My question is, how to use the FormPhoneNumber (which has a ForeignKey) when using multiple databases with manual routing. Do I need to overwrite the field employing a query employing .using('database_name')? I am aware that Django does not support cross-referencing of Foreign keys along multiple databases, but I am talking about two tables placed in the same database. How can I let the ModelForm now the database from which it can extract the foreign key options? -

Render label names instead of integer fields in Django templates
As part of my models, I have an IntergerField "choices". These choices have been labelled. (Label 1 = Straw, Label 2 = Yellow...) However, the HTML renders the integer rather than the actual labels. What do I need to do return the labels and not the field's interger? Is it somethng I need to do in views? Or do I address it directly in the html file? Code below: Models CHOICE1=( ('',''), (1,'Straw'), (2,'Yellow'), ) class Model1(models.Model): user = models.ForeignKey(User,blank=True,on_delete=models.CASCADE) Choice_A = models.IntegerField(choices=Choice1,default=0) Views def account(request): review_list = Model1.objects.all return render(request,"main/account.html", {'review_list':review_list}) HTML <h6>Champagnes</h6> {% for Model1 in review_list%} <table class="table table-hover table-striped table-bordered "> {% if Model1.user == user%} <tr> <th>Text</th><th>{{Model1.Choice_A }}</th> </tr> {%endif%} </table> {% endfor %} -
Celery results not updating after dockerization
I'm currently putting my Django app on Docker. I successfully dockerized Django, gunicorn, nginx and Celery, however when I run a Celery task, even though it's executed (displayed in the logs), the results are not stored to my database. That worked before dockerizing everything so that probably comes from my docker configurations, but I didn't manage to find which part was incorrect/incomplete. Also, I'm using the default sqlite3 Django database as I don't need to store a huge amount of data. Here is my docker-compose.yml: version: '3.8' services: django_gunicorn: volumes: - db:/db.sqlite3 - static:/static - media:/media env_file: - env build: context: . ports: - "8000:8000" command: sh -c "python manage.py migrate && python manage.py collectstatic --no-input && gunicorn main.wsgi:application --bind 0.0.0.0:8000" nginx: build: ./nginx volumes: - static:/static - media:/media ports: - "80:80" depends_on: - django_gunicorn rabbitmq3: image: rabbitmq:3-alpine ports: - 5672:5672 celery: restart: always build: context: . command: celery -A main worker -P eventlet -c 100 -l INFO env_file: - env depends_on: - rabbitmq3 - django_gunicorn volumes: - db:/db.sqlite3 volumes: db: static: media: Dockerfile FROM python:3.10.5-alpine ENV PYTHONUNBEFFERED = 1 RUN pip install --upgrade pip COPY ./requirements.txt .

Is Django able to handle PostgreSQL's truncated table names?
I am creating a Django application with PostgreSQL and some of my model names have become a bit long. Now, PostgreSQL is truncating the table name for such models to 63 characters. Please throw some light as to whether Django is able to handle such truncated table lengths on its own.. For example, consider a sample model with: App Name: MosaicApp Model Name: BeethovenBandLovedRockPopHipHopMetalReggaeLatinMetalCountryElectronicMusic Table Name created: MosaicApp_BeethovenBandLovedRockPopHipHopMetalReggaeLatinMe2dcf (or, something of this sort) Should I overlook this table name truncation? I am able to successfully apply-unapply my migrations. But it would be great if the experienced guys could throw some light as to whether this phenomenon can be overlooked. -

Unit testing with AWS Cognito and GraphQL
I'm currently writing tests for my software but got stuck at the point. I try to get data from my db with a normal GraphQL Query but my endpoint is first checking, if the idToken within the header is valid. For the user handling I'm using AWS Cognito but couldn't find a good way to mock the login to retrieve the valid token to query and mutate the data within various endpoints. Any idea how to handle this case?

Django ImageField image uploaded correctly, but not being displayed in template

Individual product detail pages with django cms
I have an e-commerce app based on Django. The product model contains basic fields like name, brand, short description, etc. So far, I only have a "generic product detail page" that displays these information for each product. Now I want to create more extensive product detail pages for some of the products with django cms so that they contain more product information and seo keywords. This means that most products would just have the "generic" detail page and some have a more extensive version. I am using a url path like mydomain.com/products/ and the view finds the respective product to be displayed using the product-slug. So far, this "/products/..." path is handled outside of the django-cms url namespace. I am rather new to django cms and unsure how I should handle this project. My first idea would be: Add empty django-cms placeholders to the generic detail page Include the /products/... path in the django-cms namespace Run a script that creates a page in django-cms for each individual product (whenever a new product is added to the database, a new django-cms page must then be added as well programatically) Go to the products of high interest and add additional content with … -

Django oAuth2 without saving the user into the database
I'm currently coding a website with Django and I successfully implemented an external oAuth2. (I'm not using any libraries) the problem is that the user is saved in the database. I would like to avoid it for hosting costs reasons. In my current project, the oAuth2 is purely for verification purposes. Is there a way in Django to log in a user in without saving him to the database? I would like the website to keep him logged in if the page is refreshed but logged out if the page is closed. Thanks! -
