Authentication with Microsoft Azure AD in a multi-tenant app
Following the documentation, registered an application with Accounts in any organizational directory. The Tenant where the application resides is in "Default Directory" and has only one user, tiagomartinsperes@gmail.com. Also, the app has user assignment (as pointed out here) set to No After, created another Tenant (different directory) and invited the external user me@tiagoperes.eu. That's the user I'm getting troubles logging into the previously created app. Then, enable the OAuth2 support using social_core.backends.azuread.AzureADOAuth2 (from here). As I try to authenticate now, it works well with tiagomartinsperes@gmail.com but with me@tiagoperes.eu gives the following error Selected user account does not exist in tenant 'Default Directory' and cannot access the application 'a9a22676-8a1c-4297-95d3-8cd89553220e' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account. -
How do I affect a single looped element in Django html?
I'm building an app in Django, using Bulma for styling. I have a Polishes model that has a favorites field, which references the User (users can save polishes to their list of favorites): models.py: class Polish(models.Model): name = models.CharField(max_length=100) image = models.CharField(max_length=400, default="https://www.dictionary.com/e/wp-content/uploads/2018/02/nail-polish-light-skin-tone.png") brand = models.ForeignKey(Brand, on_delete=models.CASCADE, related_name='polishes') favorites = models.ManyToManyField(User, related_name='favorite', default=None, blank=True) def __str__(self): return self.name The add_favorites function checks to see if the polish has been added to the user's favorites already, and if it has, it removes the polish from the list. If it hasn't, it adds it: views.py: @ login_required def add_favorite(request, id): polish = get_object_or_404(Polish, id=id) if polish.favorites.filter(id=request.user.id).exists(): polish.favorites.remove(request.user.pk) else: polish.favorites.add(request.user.pk) return redirect('favorites_list') When I render the list of polishes, I'm using Bulma cards, displaying one polish per card. In the footer of the card, I want it to say 'Save to Favorites' if the polish is not in the user's list of favoties and 'Remove from Favorites' if it is. I'm struggling to get this piece to work. It will currently show either Save to Favorites or Remove from Favorites on all of the cards. Does anyone have any insight on how to render a different message only on those that are already … -

Change color of a field in a table depending on how much time is left for the user to pay with Django
I am trying to change the color of a field in a table depending on how much time is left for the user to pay, if there are 7 days to pay it should change to yellow and if it is already the date of payment or already had to have paid it should change to red, the one that changes to red I got it, but I can't get it to change to yellow when there are 7 days to pay.

Django model foreign key cascade will not trigger delete
there two basic ways to do something when an instance gets deleted: Overwrite Model.delete Signal I used to reckon both of them serve the same purpose, just provides different ways of writing, but works exactly. However, in this occasion, I realise I was wrong: class Human(models.Model): name = models.CharField(max_length=20) class Pet(models.Model): name = models.CharField(max_length=20) owner = models.ForeignKey(Human, related_name="pet", on_delete=models.CASCADE) def delete(self, *args, **kwargs): print('------- Pet.delete is called') return super().delete(*args, **kwargs) h = Human(name='jason') h.save() p = Pet(name="dog", owner=h) p.save() h.delete() # nothing is shown Why Pet.delete Is not firing at Human.delete By the foreign cascade? Does I have to apply a signal on this? If so, would it cost more performance? I am building something very heavy, comment system, filter decent records and delete when the commented target get deleted, the comment model has many null-able foreign key fields, with models.CASCADE Set, only one of them is assigned with value. But in product delete view, I call product.delete Then triggers cascade, but comment.delete Is not firing. -

Django-select2 not loading css maybe or just form looks bad

ViewSet class variable
Now I have the following logic implemented for a GET request in Django Rest Framework: class SomeViewSet(mixins.ListModelMixin, GenericViewSet): count = None def get_queryset(self): query_set = ... # some_logic self.count = query_set.count() return query_set def list(self, request, *args, **kwargs): response = super().list(request, *args, **kwargs) response.data = {'count': self.count, 'data': response.data} return response That is, the queryset is calculated according to complex logic, and it may contain a different number of objects that need to be returned in a GET request, since I don’t have access to the query_set variable inside the list function and I don’t want to copy the query_set calculation logic, I decided do it with a class variable. But still, the feeling that this is not very correct does not leave. What other options are there? -

Django choosing which model to use in Django admin
I have three models models.py class Cluster(models.Model): blockOption= (('IMG', 'IMG'),('DESC', 'DESC'),) block = models.CharField(max_length= 100, choices=blockOption) order= models.IntegerField(null=True) post = models.ForeignKey(Post, verbose_name=('Link to Post'), on_delete=models.CASCADE) class Image(models.Model): src = models.ImageField(verbose_name=('Imagefile')) captions= models.CharField(max_length= 100, null=True) cluster = models.ForeignKey(Cluster, verbose_name=('Link to Post'), on_delete=models.CASCADE) class Description(models.Model): text=models.TextField(max_length=400) cluster = models.ForeignKey(Cluster, verbose_name=('Link to Post'), on_delete=models.CASCADE) and in admin.py class ImageAdminInline(TabularInline): extra = 1 model = Image class DescriptionAdminInline(TabularInline): model= Description @admin.register(Cluster) class ClusterAdmin(admin.ModelAdmin): inlines= (ImageAdminInline, DescriptionAdminInline) I have put ImageAdminInline and DescriptionAdminInline as inlines to ClusterAdmin. I' m planning to use ClusterAdmin to choose which admin I would be using. I hope it will be something similar to wagtail's streamfield(image above).
