Hosting static site and Django apps on Ubuntu with Nginx
I am hitting a wall on what to do here. I have tried so many variations of solutions on line and none seem to work. This is what I want to do: I have a domain example.com and a VPS running Ubuntu wth a nginx server. I have a static site that I would like accessible when going to example.com. I have a django project and applications that I would like accessible when going to example.com/apps/. I would like example.com/apps/ to be the root for all files that belong in the project. So far, my basic set up is: I can access my static site via example.com. The files are sitting in /var/www/example.com/html. I cannot access my django app correctly. When I try going to www.example.com/apps/, I can see the Django test page when you first install the software and have it running (with the rocket ship). However, when I go to example.com/apps/admin, the browser URL changes to example.com/admin and I get a 404. I have tried many things here that end up not working. I get some kind of error with the server or with Django. Nginx Using proxy_set_header SCRIPT_NAME /apps (this doesn't seem to do anything). Rewriting the … -
Problem with non-Latin letters in website links
I am programming a website using django. I have placed my website in namecheep hosting and in pythonanywhere (for testing only). I faced a problem when adding Arabic links in the project, in namecheep hosting, where when I choose the link that contains an Arabic word, it directs me directly to the page page not found. In pythonanywhere and in localhost, which accepts Arabic links normally Now I want to know whether namecheep does not accept Arabic links? Are there any settings in cpanel to solve the problem? Is there a solution to the problem? I have verified that the problem is not in the code, but rather a settings problem in the hosting -

Django ManyToManyField Validators
What's the best solution to apply following requirement? In my model I have 2 manytomany fields (team1 and team2) which contains both a list of players. If a player is in team1 he cannot be also in team2. How can I implement this logic? First idea is to use validators, but they are not supported by manytomanyfield as in the django doc, so i'm humbling ask your support for a better solution please. As of now not a single view expose a POST to create matches and only admin via django admin should be able to create matches. here the Model class Match(models.Model): date=models.DateField(auto_now_add=False,auto_now=False) team1=models.ManyToManyField(Player,related_name='team_1') team2=models.ManyToManyField(Player,related_name='team_2') score_team1=models.IntegerField( validators=[MinValueValidator(0)] ) score_team2=models.IntegerField( validators=[MinValueValidator(0)] ) -
Efficient Django query for model with foreign key to itself
I'm building a simple blog post website using Django. Basically there are two models: Post and Comment, where the comment model looks like this: class Comment: post = models.ForeignKey(Post, on_delete=models.CASCADE, related_name='comments') # A comment can have many replies, and an user can only reply to the "parent" comment (A comment which isn't a reply to any comment) reply = models.ForeignKey('self', on_delete=models.CASCADE, null=True, blank=True) likes = models.ManyToManyField(User, 'like_comments', blank=True) # Some other fields def save(self, *args, **kwargs): if self.reply is not None: self.post = self.reply.post super(Comment, self).save(*args, **kwargs) I have a class-based view which inherits Django generic DetailView to retrieve a specific post. The problem is I also want to retrieve all comments of the post, along with the replies of those comments and number of likes in an efficient way. What would be the most performant way to do so? I came up with the following way: from django.db.models import Prefetch from django.views.generic.detail import DetailView # Some views here ... class PostDetailView(DetailView): model = Post template_name = 'core/post_detail.html' context_object_name = 'post' def get_queryset(self, **kwargs): return Post.objects.prefetch_related(Prefetch('comments', queryset=Comment.objects.annotate(num_likes=Count('likes')))) However, when I inspect the query using QuerySet.query, the raw SQL looks the same as if I used "Post.objects.all()". I'm not sure if … -

Is it safe to manually delete django_sessions data rows in ProsgreSQL table?
First, let me state that I know about the Django Python session cleanup scripts, but I currently don't have easy access to the shell where the Django framework is hosted. However, I have access to the backend PostgreSQL database. I'm trying to reduce the size of the over-data tables, and I noticed that the django_session table now has over 2.8 million rows. I don't think there's ever been a cron job setup for cleanup sessions since this website started running in 2016. From what I read, the django_session table stores user sessions when they log in, and if they don't log out, it stores them. Therefore, could I remove any rows older than a specified date? DELETE FROM public.django_session WHERE expire_date < '2023-01-01' I plan to test this out on a test server, but I would like to know whether it's the right approach. Otherwise, I'll have to figure out how to get access to run the shell script to do the cleanup. -

how to connect django models?

Deleting 'disabled' when saving changes in formset
I'm creating a table with a formset from a queryset of existing objects. Few fields in the table should change, and other fields should be displayed, but not changed. For displaying non-editable fields, I use the widget with 'disabled' in the form. GET request does everything right. But the POST request does not save changes to the resolved fields, because unresolved fields are required and have disabled and blocks the sending of existing values. I tried to use jQuery from the example, but it doesn't work. Moreover, I do not understand how I can refer to different ids in the formset. Models: class Order(models.Model): car = models.ForeignKey( Car, blank=True, null=True, on_delete=models.PROTECT, related_name='car_orders', ) department = models.ForeignKey( Department, blank=False, null=False, on_delete=models.PROTECT, related_name='dep_orders', ) ...

Solution for Django model composite foreign keys
I’m working with two models in Django: Order and OrderItems. I want to establish a one-to-one relationship between them using two columns instead of the usual single column. I’m aware of solutions like SQL Alchemy’s ForeignKeyConstraint and the django-composite-foreignkey package, but I’d prefer not to use ForeignKeyConstraint and the latter isn’t compatible with Django 4.0. Is there an alternative solution available for creating a composite foreign key that references two columns in Django 4.0? class Orders(models.Model): objects = models.Manager() id = models.AutoField(primary_key=True) order_id = models.CharField(max_length=255) --------> here it should reference with two columns ( id and department_id ) orderItem = models.ForeignKey('OrderCustomers', on_delete=models.PROTECT, db_column='order_item_id', to_field='id') order_item_id = models..CharField(max_length=255) department_id = models.CharField(max_length=255) created_at = DateTimeWithoutTZField(auto_now_add=True) updated_at = DateTimeWithoutTZField(auto_now=True) def __str__(self): return self.order_id -

Error in setting SIGNING_KEY in djangorestframework-simplejwt

Django Ajax Request - JSONDecodeError: Expecting value
I am working on a Django project where I have a course enrollment system. I have a button on my HTML page that, when clicked, triggers an Ajax request to submit enrollment data. The button redirects me to a page with a form where a student can fill in data such as name, surname, phone number, email, and language level. However, I am facing an issue where the values from the HTML attributes (data-language-id, data-course-name, data-price) are not getting passed into the Django view. The Django view returns a JSONDecodeError: Expecting value when trying to parse the request body. I intend to save this data into two tables in my database: Student and Enrolment. Any insights or suggestions on how to resolve this issue and successfully save the data into these tables would be greatly appreciated. Thank you! HTML Code: <!-- This is the button triggering the Ajax request --> <div class="block1_1"> <!-- ... other HTML content ... --> <div class="block__button" onclick="submitData(this)" data-language-id="1" data-course-name="Стандарт" data-price="6000"> <a href="{% url 'index3' %}">Записатися</a> </div> </div> JavaScript Code: function submitData(clickedBlock) { var languageId = clickedBlock.getAttribute('data-language-id'); var courseName = clickedBlock.getAttribute('data-course-name'); var price = clickedBlock.getAttribute('data-price'); $.ajax({ url: "/index3/", type: "POST", contentType: "application/json; charset=utf-8", dataType: "json", data: … -

Including some records in an SQL query increases query time fivefold on Heroku
We use Django with django-guardian for object-based permissions. Recently, we have been experiencing an extreme increase in runtime of a specific query for at least one user with a lot of annotation_texthighlight . Here is the query: SELECT "annotation_texthighlight"."uuid", [omitted for readability] FROM "annotation_texthighlight" INNER JOIN "annotation_annotation" ON ("annotation_texthighlight"."annotation_id" = "annotation_annotation"."uuid") WHERE ( "annotation_texthighlight"."annotation_id" IN (SELECT U0."uuid" FROM "annotation_annotation" U0 WHERE (U0."chapter_id" = '9a481c82-c44b-4ead-94bb-48de0910877b'::uuid AND U0."min_revision_id" IN ('5a301886-e200-441f-ad8e-03c4eb9bd773'::uuid, '6f539d6f-c9eb-41e2-956e-32b4a5950c33'::uuid))) AND "annotation_texthighlight"."uuid" IN (SELECT CAST(U0."object_pk" AS uuid) AS "obj_pk" FROM "guardian_userobjectpermission" U0 INNER JOIN "auth_permission" U2 ON (U0."permission_id" = U2."id") WHERE (U0."user_id" = 1522 AND U2."content_type_id" = 89 AND U2."codename" IN ('view_texthighlight'))) ); This puzzles me quite a bit. Here are the results of my investigation so far: Copying the database from its original Heroku (Postgres 13.4, standard-2, 4GB RAM, 1.2 GB DB size) to local (stock Postgres 13 via standard Docker image) will cut the runtime ~250ms. In total, about 1200 records will be returned. The first 700 (LIMIT 700) will take ~5 seconds. The remaining (OFFSET 700 LIMIT 700) will take ~25 seconds. Removing either of the WHERE filters will reduce runtime <1s. My best guess would be a different configuration on Heroku as compared to the default Postgres … -
Django MySQL OperationalError (1045) - Access Denied for User

Celery does not see objects in the database
I know that similar questions have already been asked here, but none of the answers I found turned out to be suitable. I hope I get lucky now. So, I have a Django application using Postgres, RabbitMQ and Celery. When I run the components individually, everything works fine. The problem occurs when running through docker-compose. For some reason, celery tasks cannot find the object in the database. The object exists, moreover, it stores the celery task id (for example, for possible subsequent cancellation of the task). Here are the parts of the code relevant to the problem: # docker-compose.yml version: "3.7" services: db: image: postgres:12.4 container_name: "fbrq_db" volumes: - postgres_data:/var/lib/postgresql/data/ env_file: - .env environment: - POSTGRES_HOST_AUTH_METHOD=trust networks: - default rabbitmq: restart: always container_name: "fbrq_rabbit" image: rabbitmq:3-management-alpine ports: - 5672:5672 - 15672:15672 networks: - default app: restart: always container_name: "fbrq_app" build: . volumes: - .:/code - ./static:/code/static command: gunicorn --bind 0.0.0.0:8000 fbrq_api.wsgi ports: - "8000:8000" networks: - default celery: restart: always container_name: "fbrq_celery" build: . command: celery -A fbrq_api worker -l info env_file: - ./.env depends_on: - app - rabbitmq environment: - CELERY_BROKER_URL=amqp://guest:guest@rabbitmq:5672/ - DJANGO_SETTINGS_MODULE=fbrq_api.settings networks: - default celery-beat: restart: always container_name: "fbrq_celery-beat" build: . command: celery -A fbrq_api beat -l … -
Celery Task does not retry after a certain number of times
I have a celery task with RabbitMQ as the broker. The task calls an API and checks the response, if the response does not meet some conditions, the task retries itself with a 5 seconds countdown. The problem is that my task gets retried for exactly 279 times and after that it gets stuck in "retried" status and does not execute. Here is what my task basically does: @shared_task(name="get-progress", bind=True, max_retries=10 ** 65, acks_late=True, reject_on_worker_lost=True) def get_progress(self, object_id: str): # get progress from third party api and store in status variable if status == "available": # update object in db return else: self.retry(countdown=5) I created another task to test my configuration as follow @shared_task(name="dummy", bind=True, max_retries=10 ** 65, acks_late=True, reject_on_worker_lost=True) def dummy(self): logger.info(f"retry {self.request.retries} of {self.max_retries} with {self.request.id}") self.retry(countdown=1) The dummy task works just fine and gets retried for a ridiculously large number of times. There are no exceptions being raised, I checked if the API times out and that wasn't the case. The number 279 is really confusing me and I guess I'm missing something here. Any help would be appreciated. -
