Django join tables with two or more FK conditions
I want to join models B and C with two conditions, data_a and human in model_B, and data_a and autor in model_C, but how do I do it with Django ORM class user(models.Model): data_1 = models.CharField(max_length=60) data_2 = models.SmallIntegerField() data_3 = models.IntegerField(blank=True, null=True) class model_A(models.Model): data_1 = models.CharField(max_length=60) data_2 = models.SmallIntegerField() data_3 = models.IntegerField(blank=True, null=True) class model_B(models.Model): data_a = models.ForeignKey(model_A) human = models.ForeignKey(user) data_2 = models.IntegerField() class model_C(models.Model): data_a = models.ForeignKey(model_A) author = models.ForeignKey(user) data_1 = models.CharField(max_length=5) data_2 = models.IntegerField() additional conditions on join in django I've seen this place, but I don't know if it's applicable to my situation -
Django bulk_create() with inexistent ForeignKey
I have 2 models. For simplicity, I deleted all unnecessary fields. class User(models.Model): id = models.CharField(max_length=36, primary_key=True, null=False) age = models.IntegerFiels(default=-1) and class Device(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) Through the API, I receive information about devices and create a list with devices. devices = [] for device_data in data: devices.append( Device( user_id=device_data("user_id") ) ) Once I have the list of devices, I add it to the database. Device.objects.bulk_create(devices, ignore_conflicts=True) The problem is that if, when creating a Device, I specified a user_id that is not in the database, I will get a crash because I am trying to link with a non-existent id. Now to get around this I do the following: devices = [] users = [] for device_data in data: users.append( User( id=device_data("user_id", age = -1) ) ) devices.append( Device( user_id=device_data("user_id") ) ) Then, when saving: User.objects.bulk_create(users, ignore_conflicts=True) Device.objects.bulk_create(devices, ignore_conflicts=True) User.objects.filter(age=-1).delete() How can I make sure that when saving, if the specified user_id does not exist, this device is not added? Or add a device, while creating a User with this user_id, but with the rest of the fields by default, and then, at the end, I will delete all users, and with them all devices, where age … -

Why does the variable not change its value after admin action has been triggered?
I have two admin actions for the Feedback Model in the admin panel, approved and unapproved. The value for approved in the Feedback Model is default to False. When admin use the action to approve, it turns this value to True and unapproved will turn True to False. This works on the admin panel on the deployed site, however when I'm trying to do the test for the admin.py I ran into an error where the test_approve is passing, while the test_unapprove failed. When I try to debug the test_unapprove I set the approved value as True and then check the value of feedback.approve before the response and it came out as True, which is expected. Then I check again after the response and it still came out as True where it should come out as False. Please have a look if you have any clue why this is happening. If you need any more info please let me know! admin.py @admin.register(Feedback) class FeedbackAdmin(admin.ModelAdmin): list_display = ('username', 'body', 'lesson_id', 'created_on', 'approved') list_filter = ('approved', 'created_on') list_display_links = ('username',) search_fields = ['username', 'user_id', 'body'] actions = ['approved_feedback', 'unapproved_feedback'] def approved_feedback(self, request, queryset): queryset.update(approved=True) def unapproved_feedback(self, request, queryset): queryset.update(approved=False) test_admin.py class TestAdmin(TestCase): … -
Django data problem : new salons always with all users
Problem is that I want to create a new salon, so beginning with only the user who created it. But, when I consult my django database (with localhost:8000/admin/), I notice that every user (UserSalon) is present in every 'Salon'... However, when I print all the users of this salon in the terminal, I can see there is only this one. So wtf? I have this in my models.py: class UserSalon(models.Model): # etc. class Salon(models.Model): salon_users = models.ManyToManyField(UserSalon) # etc. and this is a part of code from my view.py: user_salon_id = request.session.get('user_salon_id') if request.method == 'POST': create_salon_form = CreateSalonForm(request.POST) try: user_salon = UserSalon.objects.get(id=user_salon_id) except UserSalon.DoesNotExist: user_salon = None if create_salon_form.is_valid(): created_id_salon = create_salon_form.cleaned_data['id_salon'] created_key_salon = create_salon_form.cleaned_data['key_salon'] new_salon = Salon.objects.create(id_salon=created_id_salon, key_salon=created_key_salon) new_salon.salon_users.clear() new_salon.salon_users.add(user_salon) new_salon.save() -
How to assign the result of a conditional to a variable in a Django template?
There are two django models, "Production" and "Season". Production has a foreign key to Season (i.e. in rails-speak Season has_many Productions, Production belongs_to Season). I have a detail view for Production, and the page sidebar has the list of all productions in the current season. {% for p in season.production_set.all %} <li class="nav-item"> <a class="nav-link d-flex align-items-center gap-2" href="{% url 'production_detail' season.id p.id %}"> {{p.name}} </a> </li> {% endfor %} {% endblock %} But I would like the nav item to be disabled for the current production being viewed. That means adding the 'disabled' class to a element, and setting the "aria-current" attribute as well. I can use if/else takes, but it ends up being quite verbose and also repetitive, given that I need this logic twice in the same html tag <a class="nav-link d-flex align-items-center gap-2 {% if p.id is not production.id %} active {% else %} disabled {% endif %}" aria-current="{% if p.id is production.id %}true{%else%}false{%endif%}" href="{% url 'production_detail' season.id p.id %}"> So I tried to assign a variable like {% with p.id is not production.id as current %} but no syntax I have tried allowed me to assign a boolean expression to a variable.

Django : IsAuthenticated and TokenAuthentication decorated views getting accessed without any Authentication Token
I have used simple-jwt for JWT authentication in a simple To-Do app. For OTP based authentication i have created a custom user model and also overridden the TokenObtainPairSerializer from simple-jwt. My token urls are working fine but my get-todos view getting accessed without any authentication. Github Repo: https://github.com/ShouravAhmed/django-react-practice-code/tree/main/Django/djtodo following is my code snippets. //urls path('get-todos/', get_todos, name='get_todos'), path('token/', TokenObtainPairView.as_view(), name='token_obtain_pair'), path('token/refresh/', TokenRefreshView.as_view(), name='token_refresh'), //views.py @authentication_classes([TokenAuthentication]) @permission_classes([IsAuthenticated]) @api_view(['GET']) def get_todos(request): resp = {'status': 200, 'message': 'success'} try: todos = Todo.objects.all() serializer = TodoSerializer(todos, many=True) resp['count'] = len(serializer.data) resp['data'] = serializer.data except Exception as e: resp['status'] = 400 resp['message'] = 'Exception Occered' resp['exception'] = str(e) return Response(resp) // models.py class User(AbstractUser): id = models.CharField(max_length=15, default="") phone_number = models.CharField( max_length=15, unique=True, primary_key=True) full_name = models.CharField(max_length=73, blank=True, null=True) address = models.TextField(blank=True, null=True) total_purchase = models.IntegerField(default=0) points = models.IntegerField(default=0) visit_count = models.IntegerField(default=0) staff_level = models.IntegerField( choices=StaffLevel.choices, default=StaffLevel.USER) created_at = models.DateField(auto_now_add=True, editable=False) updated_at = models.DateField(auto_now=True, editable=False) is_phone_verified = models.BooleanField(default=False) username = models.CharField(max_length=30, null=True, blank=True) def save(self, *args, **kwargs): self.id = self.phone_number super(User, self).save(*args, **kwargs) USERNAME_FIELD = 'phone_number' REQUIRED_FIELDS = ['full_name', 'email'] objects = UserManager() // manager.py class UserManager(BaseUserManager): use_in_migrations = True def create_user(self, phone_number, password=None, **extra_fields): if not phone_number: raise ValueError('phone number is required') user = … -
Django first() for every item
Suppose I have a model EventParticipant, which stores participant data for a given Event. Now I want to retrieve the next event participance for a list of users. The following: EventParticipance.objects.filter(user__in=userlist, start__gte=timezone.now()).order_by(start) would give me all event participances for all users in userlist that start in the future. However, I only want the first one for each user. In Postgres, this could be achieved (I think) by this: EventParticipance.objects.filter(user__in=userlist, start__gte=timezone.now()).order_by(start).distinct('user'). However, this does not work for sqlite or mysql. Obviously, as shown here, this would work, but I suppose it'd be very slow: next_occurrence_ids = [] for user in userlist: id = EventParticipant.objects.filter(user=user, .....).order_by(start).values('id').first() next_occurrence_ids.append(id) return EventParticipant.objects.filter(id__in=next_occurrence_ids Is there any other strategy I could employ? -

Timezone conversion failed due to winter hour change pytz
in my code I am trying to convert a date with pytz timezone, but due to the change to winter hour at 3 am, my code crash. I have two questions : one, why does changing hours makes the timezone conversion crash ? Two, how to avoid this bug ?
