Handling complex computation on a web app involving data from a database
Just some background. This question is to help my team and I make a decision on how to handle an app we are working on. Currently the application is hosted locally in ASP.NET C# and the complex calculations that are done are handled in SQL as a stored procedure. The data is pulled into queries and the server will handle all the calculations and return a recordset which is written to a table and the front end can access that table. So moving forward, we're thinking of moving the application to the web with Django and deciding how to handle the server side of things. So what we really wanted to understand is, how do others handle situations like these? Do we continue with the same idea and build a SQL server and do the same thing or is there a better way to solve this problem? We want to the user to be able to kick the calculations off and do other things while it runs in the background. The user shouldn't have to sit on the page because these calculation can take an hour or more depending on the complexity. We'd appreciate the thought and ideas. Thank you … -

Why doesn't {% if %} {% else %} construction work in Django template?
So I am trying to display "YOU" above the comment if it's in fact a comment that has been posted by current user, otherwise I am trying to display just a username of one who left a comment.

Redis wrong version number
I am very new to deploying my Django site on Heroku. I was trying to get Celery to work (as my Django has long processes). I was following a tutorial on how to set up Redis on Heroku. The issue now is that I am getting this error: Error accepting a client connection: error:1408F10B:SSL routines:ssl3_get_record:wrong version number (conn: fd=11) There are not many solutions online, I only kind of understand that I will need to downgrade this somehow, any suggestions on how to overcome this problem? Note that I am using the free tier for Heroku and Redis. -
Django Abstract User - how to implement it and adapt to current signal
I don't have the standard Django User model to rely on, I don't know how to refer to the instance below. Before changing to the Abstract User Model I would refer to (user=instance). I was attempting to adapt a functioning e-commerce site by removing/including aspects, one of these adaptations was a Custom User model. Could it be true that I wouldn't need the "create_or_update_user_profile" function anymore since User is now the model that is used as the AUTH_USER_MODEL? When attempting to log in as admin, this error fires: File "/workspace/Project-Saasy/profiles/models.py", line 48, in create_or_update_user_profile instance.userprofile.save() AttributeError: 'User' object has no attribute 'userprofile' So I wondering either how to add the attribute to the 'User' object, or if there another way around all of this models.py from django.db import models from django.contrib.auth.models import AbstractUser from django.db.models.signals import post_save from django.conf import settings from django.dispatch import receiver class User(AbstractUser): """ A user profile model for maintaining default delivery information and order history """ is_volunteer = models.BooleanField(default=False) is_organisation = models.BooleanField(default=False) default_phone_number = models.CharField(max_length=20, null=True, blank=True) default_street_address1 = models.CharField(max_length=80, null=True, blank=True) default_street_address2 = models.CharField(max_length=80, null=True, blank=True) default_town_or_city = models.CharField(max_length=40, null=True, blank=True) default_county = models.CharField(max_length=80, null=True, blank=True) default_postcode = models.CharField(max_length=20, null=True, blank=True) class Volunteer(models.Model): user … -
How to get last element in a ForeignKey relation?
To describe my problem I will use basic models : class Chatroom(Model): date_created = models.DateTimeField(auto_now_add=True) name = models.CharField(max_length=3000) class Message(Model): date_created = models.DateTimeField(auto_now_add=True) text = models.CharField(max_length=3000) room = models.ForeignKey( Chatroom, on_delete=models.CASCADE, related_name='messages' ) I want to display every last messages sent to a room ordered by date of creation. In practice, the user connect to the page and he can see the messages ordered by date, but only the last message of each room. Example : in the database we have: rooms = [RoomA, RoomB] messages = [ { text: 'firstA', date_created: 01/05/21, room: RoomA }, { text: 'secondA', date_created: 03/05/21, room: RoomA }, { text: 'firstB', date_created: 02/05/21, room: RoomB }, { text: 'secondB', date_created: 06/05/21, room: RoomB }, ] As a result of my queryset, I want to get last messages of each room, meaning messages [secondB, secondA]. Currently I am doing the following : messages_uids = Message.objects \ .order_by('room_id') \ .distinct('room_id') \ .values_list('pk', flat=True) queryset = Message.objects \ .filter(pk__in=messages_uids) \ .order_by('-date_created') return queryset I have only one message per room (good point), messages are ordered by date_created (good point), but I do not have the last message of each room.

DisabledBackend Error with every second reload with Django, Celery and RabbitMQ
I am using django, celery and RabbitMQ for a webserver. On my development server everything works fine. However, when I try to run the webserver on my production server with apache2/mod_wsgi every second time I reload the result page I get the following error: 'DisabledBackend' object has no attribute '_get_task_meta_for' That happens when I try to run the following command: task_state = <taskname>.AsyncResult(task_id).state My CeleryConfiguration is as following: app = Celery('<name>', broker='amqp://<user>:' + RABBITMQ_PASSWD + '@localhost:5672/<vhost>', backend='django-db', task_ignore_result=False, task_track_started=True, ) The backend is set and it works exactly every second time. I tried restarting the services, the computer and cleaning the databases. Same problem with different backends. Does anyone have an idea what could cause the problem? Thank you for your help! -
What to use instead of DO_NOTHING to only delete one field?
I want to link two models like this class t_data(models.Model): receiver = models.TextField() file_desc = models.TextField() file = models.FileField(upload_to='files') another model : class transaction_detail(models.Model): transaction_id = models.ForeignKey( t_data, on_delete=models.DO_NOTHING, ) sender=models.TextField() receiver = models.TextField() *yes i am using DO_NOTHING and i have read that it is wrong to use it. But it is not working. now when a user tries to delete his file, The t_data object should be deleted but the transaction_details should not change.There is nothing specific on my view for deleting objects. Yet, simple example would be def delete_request(request,id): requested = t_data.objects.get(id=id) requested.delete() return HttpResponseRedirect('/requests') When I try to delete the t_data object it throws an Integrity Error. How to solve it? Or what to use in place of DO_NOTHING? We can also use OneToOneField if you want to solve this problem. Thank you :) -

Django : Run task in background immediately
Similarly to this question, I don't understand how the django-background-tasks module works. What I want is to have a button which would start a task in background so it doesn't block the front. The task has to be run as soon as the click occurs. Reading the docs I thought that I only had to define my task as a function preceded by the decorator @background(schedule=1) then calling the function would start the task one second after the click handler was run. Calling notify_user as normal will schedule the original function to be run 60 seconds from now: However this is not what happens. What happens is that a new task is created after each click (I could understand that by requesting the background_task database thanks to this answer) but none ever runs. The command python manage.py process_tasks seems to run one task defined previously before stopping. If no task has been defined, then it waits for a task to be defined for up to duration seconds (specified when running the command). This behavior is not what I expected while reading the documentation. duration - Run task for this many seconds (0 or less to run forever) - default is … -

How to define extra fields when creating super user in Django?

How to hide and show "ADD" button in Django while using DRF

Django: How to take my query out of my for loop
I got the following code, that contains N queries: for qty in total_qty_bought: product_id = qty["product"] quantity = int(qty["quantity__sum"]) try: method_title = ( self.shipment_model.get(order_id=qty["order_id"]) .method_title.replace("Hent-selv", "") .strip() ) To solve the issue I tried to take the method_title query out of the for loop like this: quantity = 0 for qty in total_qty_bought: quantity = int(qty["quantity__sum"]) method_title = ( self.shipment_model.get(order_id=total_qty_bought[0]['order_id']) .method_title.replace("Hent-selv", "") .strip() ) Note! There will be a full refrence further down, to understand the bigger picture The issue in my solution is, that I am hard choosing which dict to enter , as I select [0] before order_id, and not in a for loop like before, would be selecting every individual item in the loop. Is there a more sufficient way to do this? I do not see a solution without the for loop, but django debugger tool tells me it creates 2k+ queries.

So, my HTML file is: <table> <thead> <tr> <th>Item</th> <th>Quantity</th> </tr> </thead> <tbody> {% for item in cart.get_all_items %} {% with product=item.product %} <tr> <td>{{ product.name }}</td> <td> <form action="{% url 'cart:cart_add' food.id %}" method="post"> {{ quantity_update_form.quantity}} {{ quantity_update_form.override}} <input type="submit" value="Update"> {% csrf_token %} </form> </td> </tr> {% endwith %} {% endfor %} </tbody> </table> get_all_items method would return all items in the cart and item.product is the object of Product model class. I want to set {{ quantity_update_form.quantity}} field to item.quantity and {{ quantity_update_form.override|default:True }} field to true. Is there any template tags or filters to do this? -

Django model validator using reference from Foreign Key
I was building models from a LED Strip application based in django. First of all, I have two base models, Strip and Zone, every Strip could have many zones. The Strip model has a field called max_led_number which represents the maximum number of LEDs in the strip. And the Zone model has two fields called initial_led and final_led which represents what its names says. In the validators attributes of the initial_led and final_led fields I added the MaxValueIndicator and MinValueIndicator, which works well if I gave them an integer value, but I tried to do is to pass the max_led_number to the MaxValueIndicator value as a method of validation. These are my models. class Strip(models.Model): name = models.CharField(blank=False, null=False,unique=False, max_length=250) serial_port_name = models.CharField(blank=False, null=False,unique=True, max_length=250) status = models.BooleanField(blank=False, null=False, default=False) max_led_number = models.IntegerField(default=300) def __str__(self): return(str(self.name)) class Zone(models.Model): position = models.IntegerField(blank=False, null=False, default=0, unique=False) strip = models.ForeignKey(Strip, on_delete=models.CASCADE) status = models.BooleanField(blank=False, null=False, default=False) initial_led = models.IntegerField(default=0,validators=[MaxValueValidator(strip.max_led_number), MinValueValidator(0)]) final_led = models.IntegerField(default=0,validators=[MaxValueValidator(strip.max_led_number), MinValueValidator(0)]) mode_choices = [(1,'Fixed color'),(2,'Rainbow'),(3,'Color theatre'),(4,'Rainbow theatre'),(5,'Meteor rain'),(6,'Meteor rain - Trigger')] mode = models.IntegerField(choices=mode_choices,default=0) color = models.CharField(blank=False, null=False,unique=False, default="#FFFFFF", max_length=7) def __str__(self): return("Zone " + str(self.position)) But I receive this error.

Rendering a response from request.GET as an iframe

How should I format url to enable redirection to payment stripe page? @login_required def checkout(request): try: if request.user.customer.membership: return redirect('settings') except Customer.DoesNotExist: pass if request.method == 'POST': pass else: membership = 'monthly' final_dollar = 10 membership_id = 'price_1IkjAAHziP1k1SzvFKdNwo3h' if request.method == 'GET' and 'membership' in request.GET: if request.GET['membership'] == 'yearly': membership = 'yearly' membership_id = 'price_1IkjAAHziP1k1Szv9v3TxSHn' final_dollar = 100 # Create Strip Checkout session = stripe.checkout.Session.create( payment_method_types=['card'], customer_email = request.user.email, line_items=[{ 'price': membership_id, 'quantity': 1, }], mode='subscription', allow_promotion_codes=True, success_url='http://domainname.com/success?session_id={CHECKOUT_SESSION_ID}', cancel_url='http://domianname.visyrelax.com/cancel', -
Djano ORM datetime filter
I have a simple query where I retrieve all the rows from the current date's 12 AM to current time. time_now = datetime.now() time_passed = time_now.hour * 60 + time_now.minute a = (datetime.now() - timedelta(minutes=time_passed)).strftime('%Y-%m-%d %H:%M:%S') b = datetime.now().strftime('%Y-%m-%d %H:%M:%S') result_inwardCount = MYmsEvents.objects.all().filter(recorded_at__range=[a, b],event='In-ward') print(result_inwardCount.query) print(len(result_inwardCount)) Now when I print the query, it gives me this : SELECT "m_yms_events"."id", "m_yms_events"."vin", "m_yms_events"."event", "m_yms_events"."location", "m_yms_events"."recorded_at", "m_yms_events"."sys_id", "m_yms_events"."x", "m_yms_events"."y", "m_yms_events"."last_updated" FROM "m_yms_events" WHERE ("m_yms_events"."event" = In-ward AND "m_yms_events"."recorded_at" BETWEEN 2021-05-19 00:00:37+05:30 AND 2021-05-19 16:49:37+05:30) This gives me 0 results. When I run the same query in pgAdmin it gives me 41 rows. Below is the query after adding the apostrophie : SELECT "m_yms_events"."id", "m_yms_events"."vin", "m_yms_events"."event", "m_yms_events"."location", "m_yms_events"."recorded_at", "m_yms_events"."sys_id", "m_yms_events"."x", "m_yms_events"."y", "m_yms_events"."last_updated" FROM "m_yms_events" WHERE ("m_yms_events"."event" = 'In-ward' AND "m_yms_events"."recorded_at" BETWEEN '2021-05-19 00:00:37+05:30' AND '2021-05-19 16:49:37+05:30') The timezone in Postgres is IST, so is the timezone on to the server.
