Django: safely store auth token to be share along all django users
I build a Django site wheres requires all users to be authenticated using the standard authentication of Django. In some of the pages django will be doing Request to a third party site which also require authentication. This third party site is not a django site and only has one user, this means that all django users will be sharing that 1 user to retrieve the information. The authentication to this third party site, is with a JWT Flow. We first retrieve an auth token and then we send this token to the desire end point adding the Django user ID, to retrieve that user ID information. I want to avoid all users in django doing multiple request to get the same auth token as this should be the same for all of them. Is there a way in Django to storage this auth Token safely? and perhaps if a user fail due to expiry token, django retrieves a new one and keep it safely store for all users to use? -

Django reset oneToOneField on Custom User Model
I have a custom User model, which has a one-to-one relationship with a UserProfile model. I want to create a new UserProfile object and switch the existing related UserProfile object with the newly created one. This is essentially what I am trying to do: **views.py** def perform_create(self, serializer): club = serializer.save(created_by=self.request.user) user = self.request.user user.current_userprofile = None user.save() UserProfile.objects.create( user_account=self.request.user, club=club, current_active_userprofile=self.request.user, is_admin=True ) **models.py** class UserProfile(models.Model): user_account = models.ForeignKey(UserAccount, related_name='userprofiles', on_delete=models.CASCADE) club = models.ForeignKey(Club, related_name='club_userprofiles', on_delete=models.CASCADE) current_active_userprofile = models.OneToOneField(UserAccount, related_name='current_userprofile', on_delete=models.SET_NULL, blank=True, null=True) is_admin = models.BooleanField(default=False) However, the perform_create method triggers an integrity error: UNIQUE constraint failed: userprofile_userprofile.current_active_userprofile_id How do I reset the field to NULL so that I can connect it to the newly created object? -
NameError: name *model* is not defined; ManyToManyField/ForeignKey
Here is a relationship I'm aiming for in terms of a User, Question, Bookmark relationship; Bookmark being an intermediary table: A user can bookmark many Questions (topic pages) A Question (topic page) can be bookmarked by several users The keyword here being bookmark(ed), I have created a Bookmark model to show this relationship. However there's a problem of trying to make migrations due to a NameError being raised. Depending where they are defined in the script it's raising either: NameError: name 'Question' is not defined NameError: name 'Bookmark' is not defined How can I get past this error in order to push the Bookmark into the migrations directory with its ForeignKey references? class Question(models.Model): title = models.CharField(unique=True, max_length=40) body = models.TextField() created = models.DateField(auto_now_add=True) likes = models.IntegerField(default=0) author = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.SET_NULL, null=True, blank=True ) views = models.ManyToManyField( View, related_name="+" ) tags = models.ManyToManyField( Tag, related_name="questions" ) bookmarks = models.ManyToManyField( Bookmark, related_name="+", ) def __str__(self): return self.title class Bookmark(models.Model): question = models.ForeignKey( Question, on_delete=models.CASCADE, related_name="+" ) user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="bookmarks" ) -
Implement f-string like syntax, with Django SafeString support

How create invalid email in python
I tried to find a function for my django project that creates invalid email, but I didn't find any. I found only functions that create valid emails and validators for them like this: import random import string DOMAINS = ["hotmail.com", "gmail.com", "aol.com", "mail.com", "yahoo.com", "mail.ru"] letters = string.ascii_letters def get_one_random_domain(): return random.choice(DOMAINS) def get_one_random_name(length=7): return ''.join(random.choice(letters) for i in range(length)) def get_random_email(): return get_one_random_name(letters) + '@' + get_one_random_domain() Please advise sites with similar information or links to ready-made solutions -
Nav item links not properly linking to new page
I am using Django to do this, I have a nav list with tabs and I want each tab to go to a new page and new corresponding view, the new pages will all have the same nav list, just with a different active tab. For some reason when I click on the tab, it won't change the page, I'm not sure what I'm doing wrong. Here is my code in the main page with the tabs: <ul class="nav nav-tabs"> <li class="nav-item"> <a class="nav-link active" data-toggle="tab" href="#summary">Summary</a> </li> <li class="nav-item"> <a class="nav-link external" data-toggle="tab" href="{% url 'financials:description' ticker %}">Description</a> </li> </ul> I know the link is correct, because I have tested it outside the nav links and it works fine. When I hover over the tab I see the proper URL at the bottom of page, but when I click nothing happens. I'm not sure if this has to do with javascript (I don't understand javascript yet and got the website template online). Thanks, any help greatly appreciated! -

Convenient and simple solution to receive and answer emails in a small Django app
I am developing a Django app which uses Email in some of its components (but not at its core). I am looking for a simple and cheap solution that satisfies the following requirements: Only the custom domain of the app is used (no username@gmail address) Django can send emails programmatically (error reporting, user data from forms) The admin can receive and and answer mails through an email client of their choice Solutions I have considered so far: Using my hosting provider: They understandably don't support custom email accounts for VPS customers Amazon SES: would work for sending email, but received emails would land in a S3 bucket; it is unclear to me how to connect this to an email client Sendgrid: would work for sending email, but the only way to handle inbound mail is to forward it as HTTP POST request to a view Django extensions to read and send email through the admin interface: I can't use my email client Google Workspace: seems like this could work. My issue is that it includes a lot of functionality I don't really need. Does anyone have experience with this? All I really need is to alias a standard email account … -

Why can't I use custom slugs for Parent and Children in Django Rest Framework?
I'm trying to use custom slugs for Parent and Child models. Models: # models.py class Parent(models.Model): slug = models.SlugField() class Child(models.Model): parent = models.ForeignKey(Parent) order = models.IntegerField() slug = models.SlugField() class Meta: ordering = ['order', 'pk'] def save(self, *args, **kwargs): self.slug = f"{parent.slug}/{self.order}" super(Text, self).save(*args, **kwargs) def get_absolute_url(self): return reverse("app:child-detail", kwargs={"slug": self.slug}) The Child model will use its order and the Parent's slug in its slug. I can get everything working with the default <int:pk> in the URLs but when I try to swap it to <slug:slug>, I get this error on both List and Detail views: Could not resolve URL for hyperlinked relationship using view name "app:child-detail". You may have failed to include the related model in your API, or incorrectly configured the lookup_field attribute on this field. When I try to call get_absolute_url() on a Child object (where the order is '1' and the parent's slug is 'parent-slug'), I get the following error: django.urls.exceptions.NoReverseMatch: Reverse for 'child-detail' with keyword arguments '{'slug': 'parent-slug/1'}' not found. 2 pattern(s) tried: ['api/v1/child/(?P[-a-zA-Z0-9_]+)(?P\.[a-z0-9]+/?)$', 'api/v1/child/(?P[-a-zA-Z0-9_]+)$'] URLs: # project urls.py urlpatterns = [ path("admin/", admin.site.urls), path("api/v1/", include("app.urls", namespace="app")), path("api-auth/", include("rest_framework.urls")), # login for Browserable API ] # app urls.py from django.urls import path, include from … -

Venv stops working as supposed after opening a branch in git
I had a project set up within VS-Code together with a venv (setup via "python -m venv venv") in it. Everything was working fine: Git worked and my venv did also do its job, e.g. opening python via the terminal while the venv was active would open the right python interpreter within the venv and thus find the correct libraries. I decided to open a new branch via the git command : "git checkout -b eel_replacement" and wanted to install Django afterwards via "pip install django"(while my venv was active). Installation succeded and I wanted to verify that by opening the python interpreter and trying "import django"(I also tried "import Django"), which did not work, resulting in the error: Traceback (most recent call last): File "", line 1, in ModuleNotFoundError: No module named 'django' If I type in pip list, then this is the output: pip list output There are 2 things that really got me confused right here: It does show all packages, not only the ones I installed within my venv.

check password always returns false django

How to return relative to request django
In my django project, I built a little like-button. The problem is, that I had it only when I take a detailed view on a post, and now want to put it on the home page, where multiple posts are shown. The problem the Like Function of the button returns to the detailed page, but I want to make the return dependent from the url where the like came from, so that I can just scroll ahead on the home page or what ever page am on, without being returned to another page. So here is my views.py Like function: def PostLike(request, pk): post = get_object_or_404(Post, id=request.POST.get('post_id')) if post.likes.filter(id=request.user.id).exists(): post.likes.remove(request.user) else: post.likes.add(request.user) return HttpResponseRedirect(reverse('post-detail', args=[str(pk)])) So in a nutshell: how could I change my Like function so that I am returned to the page I liked from? -

Avoid querying related tables in Django
The model: class RegistrationSlot(models.Model): event = models.ForeignKey(verbose_name="Event", to=Event, related_name="registrations", on_delete=CASCADE) hole = models.ForeignKey(verbose_name="Hole", to=Hole, null=True, blank=True, on_delete=DO_NOTHING) registration = models.ForeignKey(verbose_name="Registration", to=Registration, blank=True, null=True, on_delete=SET_NULL, related_name="slots") player = models.ForeignKey(verbose_name="Player", to=Player, blank=True, null=True, on_delete=DO_NOTHING) starting_order = models.IntegerField(verbose_name="Starting order", default=0) slot = models.IntegerField(verbose_name="Slot number", default=0) status = models.CharField(verbose_name="Status", choices=STATUS_CHOICES, max_length=1, default="A") class Meta: ordering = ("hole", "slot") constraints = [ UniqueConstraint(fields=["event", "player"], name="unique_player_registration") ] objects = RegistrationSlotManager() In the manager I declare that I always want the player: class RegistrationSlotManager(models.Manager): def get_queryset(self): return super().get_queryset().select_related("player") The primary access pattern for this data is to query by an event id, so the view filter looks like this: def get_queryset(self): queryset = RegistrationSlot.objects.all() event_id = self.request.query_params.get("event_id", None) if event_id is not None: queryset = queryset.filter(event=event_id) return queryset And what my UI wants is very simple. The serialized json object does not include related objects other than the player: { "id": 5798, "event": 344, "hole": 1, "registration": 9996, "starting_order": 0, "slot": 0, "status": "R", "player": { "id": 353, "first_name": "John", "last_name": "Dough" } } So while trying to optimize my api, this query should be one of the fastest, but it's not. The Django ORM is generating 1000+ queries that I do not want. The register_registrationslot query … -
Migrations Applied Locally but not in production
I have a django app in docker. The local setup is identical to the production one. However, the migrations are applied in the local setup but not in production.
