Use phone number / sms token instead of username password in django
I'm new to django and I'm developing a website with django, but I want to have a custom flow for register/login instead of django's default, as described below: When a user want to login/register redirects to a form that only have one field "phone number" and a submit button in the next page if the phone is belongs to a registered user, user receive a token via SMS and enter it to complete login. and if the phone isn't found, redirects to a form to receive user's information such as first/last name and SMS token to complete registering user. I know I need custom forms and custom user model, but I don't know how to implement this. Do I need to subclass my custom user model from django's AbstractUser or AbstractBaseUser? Do I need to use any plugin? Should I write a custom authentication backend? what should I do, if i want to differ between staffs and customers. So staff should login with username/password and customers use system described. I browsed some topics and tutorial about django user system and official document of django, but I feel confused and can't find my way. -

Django Email doesn't render HTML tags
I am trying to make an email notification system using Django, but there's a problem. The body of the email doesn't render html tags, and instead the body display the html tag and the message in a long line instead. Even when the message contains \n, it doesn't create a new line but the \n is not visible in the body of the email This is my email template <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>{{subject}}</title> </head> <body> {{body}} </body> </html> This is my code to send the email from django.core.mail import EmailMultiAlternatives from django.template.loader import render_to_string from django.utils.html import strip_tags from django.conf import settings class SendNotification: @staticmethod def by_email(instance): subject = instance.subject to = list(instance.receivers.values_list("to", flat=True)) html_content = render_to_string("email.html", {'subject': subject, "body": instance.message}) text_content = strip_tags(html_content) try: email = EmailMultiAlternatives( subject, text_content, settings.EMAIL_HOST_USER, to, ) email.attach_alternative(html_content, 'text/html') email.send() instance.counter += 1 instance.save() instance.receivers.all().update(status=True) any idea why the html tag is not rendered properly? -
Simple Example of Multiple ManyToMany Model Relations in Django
I'm writing a workout app and have a number of models that need to link together. Specifically, I have an Exercise model that needs to track the name of each exercise as well as the primary and secondary muscle groups targeted by the exercise. I also need a muscle group model, and these all need to link together in a ManyToMany fashion, e.g. any muscle group be associated with the primary and/or secondary or multiple exercises and vice versa. How do I write the code to define the classes, as well as write a script to populate the database and test how to access various fields? Answered below as hopefully a useful super intro tutorial for others since I couldn't find something so easily online. -

Uploading multiple images no longer working after updating from django 3 to 4

How to serve InMemoryStorage media files during Django tests
I have some Selenium-based integration tests (subclassed under django.contrib.staticfiles.testing.StaticLiveServerTestCase) for my Django app that require a functioning user-uploaded media configuration. I've been using S3 storage (django_s3_storage.storage.S3Storage from etianen/django-s3-storage) and that works just fine, but it incurs S3 costs each time I run my tests, plus the network overhead of going out to S3 is a lot during some of my media-heavy tests. The newly added (in Django 4.2) InMemoryStorage solves both of these problems (S3 costs and overhead) perfectly, but I can't get the test server to actually serve the uploaded media files. I've added: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) to my urlpatterns.py, but that has no effect since Django tests are always run with DEBUG=False. But even if I force it in to my urlpatterns by inlining the relevant portion of django.conf.urls.static.static like so: import re from django.views.static import serve urlpatterns += [ re_path( r"^%s(?P<path>.*)$" % re.escape(settings.MEDIA_URL.lstrip("/")), serve, kwargs={"document_root": settings.MEDIA_ROOT}, ), ] it still doesn't work since the serve function looks like it's not storage-aware; it only works with media files on the filesystem. The result is that my media files all return 404s when my Selenium browser requests them. Is there a storage-aware equivalent to django.views.static.serve that I can … -

Django Admin - Proxy model loses edit/add on Foreign Key fields and no auto-complete?
Goal: I want to group some of my models inside of other apps on the Admin page.

If I register the original model with the admin model, it displays fine. (original)--> (proxy) Issue 2: If I set autocomplete_fields inside the corresponding admin models, I get an error that the original model should be registered. But I want to only register the proxy model, not both ? -

Migration file errors when trying to get rid of a third party Django app
I'm working on a Django Project that currently uses the third party app Oscar. We're in the process of migrating away from Oscar, to a custom-built shop, and for this we want to get rid of a bunch of old files, models and of course the actual third party dependencies. But I am having a hard time doing this because the migration files keep throwing up errors. The situation is that we have first-party models that depend on Oscar's models. For example: from oscar.apps.catalogue.models import Product class Executable(Model): exec_hash = CharField(max_length=64, unique=True) product = ForeignKey(Product, blank=True, null=True, on_delete=CASCADE) version = CharField(max_length=32) os = CharField(max_length=32) update_url = CharField(max_length=128, blank=True) This means we have a migration file that contains the code to create this table: migrations.CreateModel( name="Executable", fields=[ ("id", models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name="ID")), ("exec_hash", models.CharField(max_length=64, unique=True)), ("version", models.CharField(max_length=32)), ("os", models.CharField(max_length=32)), ("update_url", models.CharField(blank=True, max_length=128)), ( "product", models.ForeignKey( blank=True, null=True, on_delete=django.db.models.deletion.CASCADE, to="catalogue.product" ), ), ], ), The product field from this Executable needs to be removed, so I removed the field from the model and created a new migration. Now I want to remove all the Oscar apps from my INSTALLED_APPS list, but this is causing a whole lot of headaches because when I … -

How to notify multiple separate cached Django read-only instances when a view has changed?
I am considering a Django stack for a site with high-frequency read (GET) events and low-frequency write (POST) events. Suppose there are a large number of read-only instances which are all serving GET events and caching various views. There are a smaller number of non-cacheing writeable instances which handle POST events. These instances are all independent and might be running on separate machines, although they access the same central database. Now suppose there is a POST event which invalidates, say, a user's e-mail address. Then various views across the various read-only instances need to invalidate their caches. Is there a standard way to implement this pattern within the Django framework, or do I need to do this myself? (Or there a much better totally different way to do this?) -

However, when I deploy it on Heroku, I'm getting the following error: heroku log `2023-09-29T13:50:20.958856+00:00 heroku[web.1]: State changed from crashed to starting 2023-09-29T13:50:24.630050+00:00 heroku[web.1]: Starting process with command `daphne nanochat.asgi:application --port 16299 --bind 0.0.0.0 -v2` 2023-09-29T13:50:25.627718+00:00 app[web.1]: Traceback (most recent call last): 2023-09-29T13:50:25.627755+00:00 app[web.1]: File "/app/.heroku/python/bin/daphne", line 8, in <module> 2023-09-29T13:50:25.627769+00:00 app[web.1]: sys.exit(CommandLineInterface.entrypoint()) 2023-09-29T13:50:25.627785+00:00 app[web.1]: File "/app/.heroku/python/lib/python3.10/site-packages/daphne/cli.py", line 171, in entrypoint 2023-09-29T13:50:25.627826+00:00 app[web.1]: cls().run(sys.argv[1:]) 2023-09-29T13:50:25.627827+00:00 app[web.1]: File "/app/.heroku/python/lib/python3.10/site-packages/daphne/cli.py", line 233, in run 2023-09-29T13:50:25.627875+00:00 app[web.1]: application = import_by_path(args.application) 2023-09-29T13:50:25.627876+00:00 app[web.1]: File "/app/.heroku/python/lib/python3.10/site-packages/daphne/utils.py", line 12, in import_by_path 2023-09-29T13:50:25.627909+00:00 app[web.1]: target = importlib.import_module(module_path) 2023-09-29T13:50:25.627909+00:00 app[web.1]: File "/app/.heroku/python/lib/python3.10/importlib/__init__.py", line 126, in import_module 2023-09-29T13:50:25.627951+00:00 app[web.1]: return _bootstrap._gcd_import(name[level:], package, level) 2023-09-29T13:50:25.627952+00:00 app[web.1]: File "<frozen importlib._bootstrap>", line 1050, in _gcd_import 2023-09-29T13:50:25.628008+00:00 app[web.1]: File "<frozen importlib._bootstrap>", line 1027, in _find_and_load 2023-09-29T13:50:25.628030+00:00 app[web.1]: File "<frozen importlib._bootstrap>", line 1006, in _find_and_load_unlocked 2023-09-29T13:50:25.628055+00:00 app[web.1]: File "<frozen importlib._bootstrap>", line 688, in _load_unlocked 2023-09-29T13:50:25.628081+00:00 app[web.1]: File "<frozen importlib._bootstrap_external>", line 883, in exec_module 2023-09-29T13:50:25.628117+00:00 app[web.1]: File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed 2023-09-29T13:50:25.628142+00:00 app[web.1]: File "/app/./nanochat/asgi.py", line 16, in <module> 2023-09-29T13:50:25.628169+00:00 app[web.1]: … -
Error while reading a csv file in django rest framework
I am simply trying to read a csv file in django rest framework but its giving me this error and I can't seem to find what is the issue because I also tried reading the file in 'r' mode. Error _csv.Error: iterator should return strings, not bytes (the file should be opened in text mode) Views.py (csv reading code) csv_file = request.FILES["Bus"] data = [] with csv_file.open('r') as file: reader = csv.DictReader(file) for r in reader: print(r) I am using postman to send the csv file for testing
