Does the post_save signal work continuously in Apache server?When it is executed behind Apache, just when we refresh the page it again saving the same password in next password column as the previous password column.I need to check password history for 5 passwords to not repeat.The post_save code: def check_oldest_password_instance(mbox): passwd_list = [] oldest_password = None oldest_password_datetime = datetime.now() pfield = '1' n = 0 mphistory = Phistory.objects.filter(mbox=mbox) if mphistory: print('======phistory exists====', mphistory) for p in mphistory: if p.password1: passwd_list.append(p.password1) oldest_password_datetime = p.datetime1 oldest_password = p.password1 pfield = '1' if p.password2: passwd_list.append(p.password2) if oldest_password_datetime > p.datetime2: oldest_password_datetime = p.datetime2 oldest_password = p.password2 pfield = '2' if p.password3: passwd_list.append(p.password3) if oldest_password_datetime > p.datetime3: oldest_password_datetime = p.datetime3 oldest_password = p.password3 pfield = '3' if p.password4: passwd_list.append(p.password4) if oldest_password_datetime > p.datetime4: oldest_password_datetime = p.datetime4 oldest_password = p.password4 pfield = '4' if p.password5: passwd_list.append(p.password5) if oldest_password_datetime > p.datetime5: oldest_password_datetime = p.datetime5 oldest_password = p.password5 pfield = '5' print(len(passwd_list),pfield,'passwd_list_len,pfield_oldest') n = len(passwd_list) # For new mailbox, check if all 5 values are populated # if n == 0: # pfield = '1' if n == 1: … -

How to set different permissions for GET and POST methods with ListCreateAPIView?
I would like to set IsAuthenticated permission for GET and IsTeamLeader permission for POST with ListCreateAPIView and ModelSerializer, but without having a unique permission that check the request method in has_permission, as suggested in these questions here and here. How could I do that ? @permission_classes([IsAuthenticated]) class ManagerListView(ListCreateAPIView): queryset = Manager.objects.all() serializer_class = ManagerSerializer class IsTeamLeader(permissions.BasePermission): def has_permission(self, request, view): if Manager.objects.filter(pk=request.user.pk).exists(): return Manager.objects.get(pk=request.user.pk).is_team_leader class ManagerSerializer(serializers.ModelSerializer): password1 = serializers.CharField(write_only=True) password2 = serializers.CharField(write_only=True) fields = serializers.JSONField(write_only=True) def validate(self, data): if data['password1'] != data['password2']: raise serializers.ValidationError('Passwords must match.') return data def create(self, validated_data): data = { key: value for key, value in validated_data.items() if key not in ('password1', 'password2') } data['password'] = validated_data['password1'] user = self.Meta.model.objects.create_user(**data) return user class Meta: model = Manager fields = ('id', 'email', 'first_name', 'last_name', 'username', 'role', 'is_team_leader', 'password1', 'password2', 'fields') read_only_fields = ('id', 'first_name', 'last_name', 'role', 'is_team_leader', 'address', 'contact') -
How do I run a function in the background of my Django server and send the output to the correct view?
I have a queue of users defined as: class QueueItem(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) In addition, I have the following functions to interact with the queue: def should_pair(user1, user2): # Add user preferences later # compare the attributes of the two users and return True if they should be paired, False otherwise if user1.school == user2.school: return True return False def pair_users(): # get all users in the queue users = QueueItem.objects.all() # pair users two at a time for i in range(0, len(users), 2): user1 = users[i] try: user2 = users[i + 1] except IndexError: return None if should_pair(user1, user2): return [user1, user2] return None My question is, is there a way that I can run the pair users function constantly in the background, and when it finds a match, send a common url for the 2 users to a view that can redirect the users to the common link? This is for a video chat app that connects random users (similiar to Omegle). -

Is it necessary add IsAuthenticated permissions to permission_classes in view that is inherited from LoginRequiredMixin
I have a class-based view called ProfileDetail. It is inherit LoginRequiredMixin from django.contrib.auth.mixins. And then set permission_classes = (IsAuthenticated,). Basically all client that view ProfileDetail is already logged-in, hence authenticated. My question is, is it necessary to set permission_classes = (IsAuthenticated,) even though all client already logged-in? What's your advice? Thank you. -

Figuras interactivas HTML CSS JS DJANGO
Pará un proyecto de Django con HTML CSS y JS me piden poner una figura de un cuerpo humano en la que se puedan seleccionar articulaciones haciéndoles click y se marque un checkbox que tenga encima la articulación. Es decir, tiene que haber un checkbox posicionado encima de cada articulación y se tiene que poder intersctuar independientemente con cada uno. Alguna ayuda? Gracias! La única solución que se me ocurrió es posicionar la imagen del cuerpo fija y posicionar (también fijo) cada checkbox, pero me parece un laburo muy pesado y creo que debería haber alguna otra forma. -
Django 'runserver' displays blank page. It returns the source code and shows no errors. This problem was not here the last time I opened VS Code
I am doing a CS50 Web Project and it worked just fine until today. Now when I run the command 'python3 manage.py runserver (any port I want)' it displays: Just a blank page Django shows no errors, the settings are fine. the '/admin' page functions without issues and the page source code is shown without issues. This is not a Jinja syntax problem as well, as I checked it was correct to. It shows this blank screen no matter the URL I go too. If I open a live server it 'works' in that it displays contents to me. For example: Using this comand: Live server VS command It displays at least something close to the page: 'Live' display. !!! - I got also {% endblock %} at the end. I tried: Opening it with Live server, it displays contents, however, obviously, not what I need. Chaning the settings, they are fine. Chaning the port, that's not the issue. Checking the Jinja syntax, that's not the issue. Restarting VS code, no change (the last time, once again, had no issues regarding such problems). What is interesting is that if I remove all the code from a template like 'index.html': If … -

Facebook comment section for multiple pages
I am trying to add a Facebook comments section on each page in my website. For example, pk=27 (https://www.donadogs.org/en/dogs/27/) should have its own section and pk=28 a different one. https://developers.facebook.com/docs/plugins/comments#configurator allows me to create a section per URL provided. This means that I can't add a section for each separate PK on my website as each URL has to be provided manually. Is there a workaround to this? -

How to test Django API that uses Celery task with send_email?
So, in my Django project, I have an API view that sends data by email to the user. That job doing by Cerely (celery task). I want to test that API sends the right data. But I can't realize how to do that with that celery job, because the user created in a testcase has a non-exist email. So even if I run celery worker in a test it'll fail due to the wrong email with SMTP error... If we implement the view without celery we can use Django mail.outbox[0].body to inspect the mail. But with Celery we can't. Pls, advise. -

Here are my post and post image models: class Post(models.Model): EV = "Everybody" FO = "Followers" FR = "Friends" AUDIENCE = [ (EV, "Everybody"), (FO, "Followers"), (FR, "Friends"), ] category = models.ForeignKey(Category, on_delete=models.SET_DEFAULT, default=1) body = models.TextField("content", blank=True, null=True, max_length=5000) slug = AutoSlugField(populate_from=["category", "created_at"]) video = models.FileField(upload_to=user_directory_path, null=True, blank=True) can_view = models.CharField(max_length=10, choices=AUDIENCE, default=EV) can_comment = models.CharField(max_length=10, choices=AUDIENCE, default=EV) user = models.ForeignKey( User, on_delete=models.CASCADE, verbose_name="user", related_name="user" ) published = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) class Meta: verbose_name = "post" verbose_name_plural = "posts" db_table = "posts" ordering = ["created_at"] def __str__(self): return self.body[0:30] def get_absolute_url(self): return self.slug class PostImage(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name="post") image = models.FileField( upload_to=post_directory_path, default="posts/default.png", null=True ) class Meta: db_table = "post_images" ordering = ["post"] def image_tag(self): return mark_safe( '<img src="/storage/%s" width="50" height="50" />' % (self.image) ) image_tag.short_description = "Image" This is the post and post images serializers: class PostImageSerializer(serializers.ModelSerializer): class Meta: model = PostImage fields = ["id", "image", "post"] extra_kwargs … -
