Can't get Apache web server to show my django app
On the server I can run python manage.py runserver 0.0.0.0:8000 on the server and it renders my app fine. When I try via Apache, I get the infinite load and nothing renders. Spent too much time trying to troubleshoot and can't figure it out. Any help is appreciated! Here's my configs. <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host.

Email verification fails everytime in django project
I am making a project in Django in which I need the users to go through an email verification. The email verification link is being generated and sent to the user on the email provided on signup. However when the confirm_email function(provided below) is called to check, it always results in failure(failure.html is shown everytime). def confirm_email(request, uidb64, otp): try: uid = force_bytes(urlsafe_base64_decode(uidb64)) user = User.objects.get(pk=uid) print(user, uid, otp) except (TypeError, ValueError, OverflowError, User.DoesNotExist): user = None if user and default_token_generator.check_token(user, otp): user.is_active = True user.save() return render(request, 'path to email_confirmation_success.html') else: return render(request, 'path to email_confirmation_failure.html') What can be the issue here?

No profile page member found matching the query: Profile page of all users (except admin) does not render)

Can't able to update latest migrations in CICD using GITHUB actions

Django: Select objects that have a duplicate value when related to same secondary object
I want to find objects with duplicate values for a specific field, but only if they are related to the same secondary object. For example, with the following models: class Blog(models.Model): name = models.CharField(max_length=100) ... class Entry(models.Model): blog = models.ForeignKey(Blog, on_delete=models.CASCADE) headline = models.CharField(max_length=255) pub_date = models.DateField() ... How do I select all Entry objects that have the same headline IF they are published in the same Blog. So headlines shared between blogs should not be included. (Bonus: An extra filter that extracts only duplicate headlines with the same publication date, still within the same blog). The closest solution I have is based on this answer: https://stackoverflow.com/a/8989348/20488494 The first part, obtaining duplicate values, is successful: dupe_entries_vals = ( Entry.objects .values('blog', 'date') .order_by() .annotate(count=Count('date')) .filter(count__gt=1) ) But then I can't use the second part because it loses related object filtering. The PKs are also lost due to taking values (necessarily, otherwise the duplicate filtering fails), so I can't use those either. # No longer restricted to related blog dupe_entries = Entry.objects.filter(headline__in=[e['headline'] for e in dupe_entries_vals]) # KeyError (id not in `dupe_entries_cals`) dupe_entries = Entry.objects.filter(pk__in=[e['id'] for e in dupe_entries_vals]) So is there a nice solution for this? -

While I want the phone number to be stored in the phone number table and displayed together with the fields of the student or adviser model in form. in other words, I need to receive the phone number along with the student or adviser model fields, but it must also be stored in the PhoneNumber table.

Why is Vue not adding the base path to some pages but to others
I have a Django backend and a Vue3 front end and everything works fine but on one page and in one component Vue is not adding the base url to the image src, so the images are not being displayed. Nothing is different from the component and view and the other components and views. So here is the part that gets the user profile pic from the localstorage which I save after login <div class="topUser" v-if="store.account != undefined && store.loggedIn" > <div class="pointer" @click="toggleSub" v-if="store.loggedIn"> <img class="profilePic" v-if="store.account.user.profile.profile_picture !== null" :src=" 'http://localhost:8000' + store.account.user.profile.profile_picture " alt="Profile Image" /> <img class="profilePic" v-else src="../assets/img/user.png" alt="Default Image" /> </div> </div> The 'http://localhost:8000' + I have to put there otherwise the image will not display The data that is in the store to feed the picture is this: store.account.user.profile.profile_picture:"/storage/user_6/profiles/1/images/tumblr_1580180affd193225f45aafa4039c395_c0ff6e67_540_pkdm85S.jpg" So ultimately I want to know why is Vue not adding the base url to the component and view but it adds it to all the other components and views? There is really nothing different in how the app gets the data. It's a worry because then what prevents it from adding the base url for some users and for others not? Is there a … -

Reverse Serializing Many to Many Relations Causes RecursionError
Following on from this answer, I've attempted to reverse serialize objects from a many to many relationship. Using a serializer method field, I've tried to populate the people that have a person type however this is causing a RecursionError from django. I can see the issue, PersonA has PersonTypeA who has PersonA etc. but I'm not sure how to 'flatten' the returned people to one level. How can I overcome the recursion error? Models: class PersonType(models.Model): name = models.CharField(max_length=128) created = models.DateTimeField(auto_now_add=True) last_updated = models.DateTimeField(auto_now_add=True) start_time = models.DateTimeField() end_time = models.DateTimeField(null=True) class Person(models.Model): title = models.CharField(max_length=16) first_name = models.CharField(max_length=128) last_name = models.CharField(max_length=128) email_address = models.CharField(max_length=256) created = models.DateTimeField(auto_now_add=True) last_updated = models.DateTimeField(auto_now_add=True) start_time = models.DateTimeField() end_time = models.DateTimeField(null=True) person_types = models.ManyToManyField(PersonType, related_name="people") Serializers: class PersonTypeSerializer(serializers.ModelSerializer): people = serializers.SerializerMethodField() class Meta: model = PersonType fields = '__all__' def get_people(self, obj): people = obj.people.all() response = PersonSerializer(people, many=True).data return response class PersonSerializer(serializers.ModelSerializer): person_types = PersonTypeSerializer(many=True) class Meta: model = Person fields = '__all__' depth = 1 -

Celery task not executing in Django project with Redis broker
I'm working on a Django project where I'm using Celery with a Redis broker to run asynchronous tasks. I have a task that is supposed to run every minute, but it's not executing as expected. The task is received by the Celery worker, but it doesn't seem to be executed. Here's the code for my task: # socials/tasks.py from celery import shared_task import logging logger = logging.getLogger(__name__) @shared_task def hello(): logger.info("Hello") print("Hello") And here's my Celery configuration in Django settings: # settings.py CELERY_BROKER_URL = 'redis://localhost:6379/0' # I'm running Redis locally CELERY_BEAT_SCHEDULE = { 'every-minute': { 'task': 'socials.tasks.hello', 'schedule': crontab(minute='*/1') }, } I'm running the Celery worker and beat services with the following commands: celery -A my_project worker --loglevel=info celery -A my_project beat --loglevel=info The worker log shows that the worker is running and the socials.tasks.hello task is registered: [tasks] . socials.tasks.hello The beat log shows that the beat service is running and connected to the Redis broker: Configuration -> . broker -> redis://localhost:6379/0 However, the hello task is not executing. There are no error messages in the logs, and the task doesn't print "Hello" or log the message "Hello". I've checked that the Redis server is running, and the worker … -
How to display images in webpage in django with multiple apps
I currently have 2 applications. When I first made the first app it was displaying the images correctly. I would upload the images in the admin console then the image would be displayed in the webpage. Feeling confident I made another app on the same project with a different purpose but recycled the code to display images and now both apps are no working.

Django post_save signal, executing chained tasks
When I save a model I want to create some folders, then download a few things to those folders. Folders need to be created for the downloads, obviously, downloads can happen in parallel. HEre's what I have: @receiver(post_save, sender=Game) def after_game_model_save(sender, instance, created, **kwargs): logger.info("after_game_model_save") task = None task_id = uuid4() tasks_chain = chain(create_game_folder.s(instance.id)) if created: tasks_chain |= download_game.s(instance.id, instance.download_link).set( task_id=str(task_id) ) else: if instance.tracker.has_changed("screenshots_urls"): tasks_group = group( [ download_game.s(instance.id, instance.download_link).set( task_id=str(task_id) ), download_screenshots.s(instance.id), ] ) if instance.tracker.has_changed("download_link"): tasks_group = group( [ download_game_update.s(instance.id, instance.download_link).set( task_id=str(task_id) ), download_screenshots.s(instance.id), ] ) tasks_chain |= tasks_group tasks_chain.delay() try: task_obj = Task.objects.get(game=instance) task_obj.task_id = str(task_id) task_obj.save() except Task.DoesNotExist: Task.objects.create(game=instance, task_id=str(task_id)) I'm getting the error TypeError: download_game() takes 2 positional arguments but 3 were given If I interpret the examples correctly, the result of the first chained task get's sent as an argument to the second task? How can I chain tasks so they're executed in order without worrying about this? The functions return nothing. So I guess right now I end up with something like download_game.s(instance.id, instance.download_link, None)
