How can I patch a celery task
I'd like to know how I can write unit tests to test a celery task correctly. Unfortunately, the internet gives testing examples of very simple celery tasks. My case looks as follows: I have a custom admin command which is a celery task that does 3 things: Makes a xlsx file from DB data, Uploads the xlsx file to s3, Send a link to the file to the request user (admin). I'd like to test 2 assertions: to test the file itself (that the xlsx file has correct DB data). But I don't understand how I can read the file which is created in the celery task to compare what the file has against the data in the DB. to test that the link is sent to the admin correctly. (I can do it in my second attempt) The code looks like this: Admin site: @admin.register(MyModal) class MyModelAdmin(admin.ModelAdmin): def export_xlsx(self, request, queryset): my_celery_task.delay(ids, queryset, request.user) actions = [export_xlsx] Celery task: @app.task(ignore_result=True) def my_celery_task(ids, queryset, user): # 1) makes a xlsx wb = openpyxl.Workbook() ws = wb.active # blablah wb.save(filename='/tmp/temp.xlsx') # 2) uploads to s3 s3 = boto3.resource('s3', aws_access_key_id=settings.AWS_ACCESS_KEY_ID, aws_secret_access_key=settings.AWS_SECRET_ACCESS_KEY, endpoint_url=settings.AWS_S3_ENDPOINT_URL) s3.Bucket(settings.AWS_STORAGE_BUCKET_NAME).upload_file('/tmp/temp.xlsx', 'file.xlsx') # 3) sends a link to the admin … -

PyTorch AssertionError: "Torch not compiled with CUDA enabled" in Django application
I'm encountering an issue in my Django application where I'm using PyTorch to initialize a model, and I'm getting an AssertionError with the message "Torch not compiled with CUDA enabled." This happens when trying to access GPU functionality. Details: Django Version: 3.0.5 Python Version: 3.6.2 PyTorch Version: CUDA Version: [12.3] Operating System: [win 11] Code Snippet: python Copy code # Relevant code snippet where the error occurs from torch import Model # ... def predict_page(request): model = Model(2).cuda() # ... Troubleshooting Steps Taken: Checked PyTorch installation. Verified CUDA installation. Updated PyTorch and CUDA to the latest versions. Conditionally initialized the model based on GPU availability. Checked GPU availability using torch.cuda.is_available(). Additional Notes: I've ensured that my system has a compatible GPU. I've restarted the Django development server after making changes.

Django dynamic formsets hidden field error
I wanted to add button for dynamcially adding an instance of formset in dajngo. I use django-dynamic-formset for this. The problem is that if I add formset by the button and try to submit the below error appears: (Hidden field TOTAL_FORMS) This field is required. (Hidden field INITIAL_FORMS) This field is required. I read that it is caused by not including "form.managment_form" in a template, but I've included it: Here is a template code: {% extends "mainapp/base.html" %} {% block content %} {% load static %} {% load widget_tweaks %} <!-- Include necessary scripts and CSS for dynamic formset --> <script type="text/javascript" src="{% static 'jquery-3.7.1.min.js' %}"></script> <script type="text/javascript" src="{% static 'jquery.formset.js' %}"></script> <!-- <link rel="stylesheet" type="text/css" href="{% static 'formset/jquery.formset.css' %}"> --> <div id="input-div1"></div> <div class="input-div2"> <form method="post"> {% csrf_token %} {{ simulation_form.initial_amount.label_tag }} {{ simulation_form.initial_amount|add_class:"form-control"}} {{ simulation_form.number_of_simulations.label_tag }} {{ simulation_form.number_of_simulations|add_class:"form-control" }} {{ simulation_form.number_of_trades.label_tag }} {{ simulation_form.number_of_trades|add_class:"form-control" }} <br> <div class="strategy-formset"> {{ strategy_formset.management_form }} {% for form in strategy_formset %} {{ form.as_p }} {% endfor %} </div> <button type="submit" name="save" class="btn btn-primary">Submit</button> </form> </div> <script type="text/javascript"> $(function () { $('.strategy-formset').formset({ prefix: '{{ strategy_formset.prefix }}' }); }); </script> {% endblock %} Do you know what else can cause this error?

Why I'm receiving the 'Connection time out' when I try to run the 'python manage.py migrate' code on putty?
Ok, I'm trying to deploy a Django project using EC2 instance I've already created an RDS/Postgree database and test it through my IDE before deploy it and it's working correctly But when I try to run the 'python manage.py migrate' code on putty I'm receiving this error angtradingdb.xxxxxxx.rds.amazonaws.com" (xxxxxxx), port 5432 failed: Connection timed out I've set 2 inbound rules on my RDS instance: First I put PostgreSQL as 'Type', 'TCP' as Protocol, 5432 as 'Port Range' and my IP as 'Source' Second inbound rule, it's the same thing but the VPC security group of my EC2 application as 'Source' I've done that before and those 2 rules where enough for the deployment to work Any idea of what can be causing this error? -
Django stops serving static files after a while
I recently built my first website with Django, loaded up all my static files, both js and scss scripts, and some pics. All works well, file uploads work, etc. Works fine after deploying to Azure as well. The problems started some time ago when my css stopped generating any changes in the pages layout (its not the scss mapping cause it works locally, and I see the changes in the css). I checked and when it occurs js files dont work also. It only loads up the changes up to my last commit and nothing after it, even though the server loads up the files from the disk with no errors. I thought it has something do to with version conflicts in the git but I resolved all of them, and it still didn't fix it. Tried restarting chrome, deleting cache files, hard reset. Collectstatic doesn't do anything at all. It sometimes works, and then just stops. Restarting the server, even the computer (I am desperate) doesn't work either. I checked the settings.py and the static files are all routed correctly: STATIC_URL = 'static/' STATIC_ROOT = BASE_DIR / 'mainsite/static' I am in debug mode when I develop the app locally. … -
Django with mypy: How to resolve incompatible types error due to redefined field for custom `User` model class that extends "AbstractUser"?
I have an existing Django project which uses a custom User model class that extends AbstractUser. For various important reasons, we need to redefine the email field as follows: class User(AbstractUser): ... email = models.EmailField(db_index=True, blank=True, null=True, unique=True) ... Typing checks via mypy have been recently added. However, when I perform the mypy check, I get the following error: error: Incompatible types in assignment (expression has type "EmailField[str | int | Combinable | None, str | None]", base class "AbstractUser" defined the type as "EmailField[str | int | Combinable, str]") [assignment] How can I make it so that mypy allows this type reassignment? I don't wish to just use # type: ignore because I wish to use its type protections. For context, if I do use # type: ignore, then I get dozens of instances of the following mypy error instead from all over my codebase: error: Cannot determine type of "email" [has-type] Here are details of my setup: python version: 3.10.5 django version: 3.2.19 mypy version: 1.6.1 django-stubs[compatible-mypy] version: 4.2.6 django-stubs-ext version: 4.2.5 typing-extensions version: 4.8.0 -

How to access a Django variable in an external JavaScript?

Let's say I have the following home.html template: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home</title> <link rel="icon" type="image/png" href="{% static 'images/favicon-32x32.png' %}" > <link rel="stylesheet" href"/stylesheet_url"> </head> <body> </body> </html> and urls look like that: urls = [ path('home/', home) ] and home view is: def home(): return render(request, 'home.html') how should the any-referral view and any-referral url look like, so I could process request that uses any referral from inside of any resourse? The Idea for url is that if I firstly specify all the concreate urls, then the last url in urls could be matching any url left. But the main problem seems that the veiw does not trigger on any url pattern (currently my everymatching url looks like path('<path:referral>', any_refferal). Also I suspect that there stands a different mechanism behind using referrals from inside of page, compared to one that that processes the page -
How to do visudo edit in sudoers.d automatically in Python?
I have a complex django-application and want to add the option for the user to shutdown the server (a Raspberry Pi) from the django-webmenu. Because the django-process on the Raspi does not have sudo privileges, I decided to give the shutdown privilege to my user via an additional configfile in sudoers.d. So I added two lines to execute to my installation instructions: To create the new file with visudo: sudo visudo -f /etc/sudoers.d/shutdown_privilege And than add one line to that file: cam_ai ALL=(root) NOPASSWD: /sbin/shutdown This works nicely, but now I would like to move this complication into my (Python-)installation script. This does not work. What am I doing wrong? I tried several things: subprocess.call(['sudo', 'touch', '/etc/sudoers.d/shutdown_privilege']) subprocess.call(['sudo', 'sed', '-i', '$acam_ai ALL=(root) NOPASSWD: /sbin/shutdown' , '/etc/sudoers.d/shutdown_privilege']) cmd = 'echo "cam_ai ALL=(root) NOPASSWD: /sbin/shutdown" | sudo tee -a /etc/sudoers.d/shutdown_privilege' subprocess.call(cmd, executable='/bin/bash') The only thing that worked is the touch command in the first line. The rest stops the program execution or does just nothing... -
django-smart-selects query filter
I am using django-smart-selects to create chained dropdown forms, problem is I cannot filter querysets made by this package since it creates its own formsets. normally i would override init such : def __init__(self,*args, **kwargs): super(BookingForm, self).__init__(*args, **kwargs) self.fields['booked_time'].queryset = AvailableHours.objects.filter(status=True) in my forms.py but now this package is overriding entire form in admin and in user views. I need to filter the query so that only objects with Status=True are fetched my forms.py : class BookingForm(forms.ModelForm): class Meta: model = Bookings exclude = ('user','booking_code','confirmed',) def __init__(self,*args, **kwargs): super(BookingForm, self).__init__(*args, **kwargs) self.fields['booked_time'].queryset = AvailableHours.objects.filter(status=True) my models.py: AVAILABLE_DATE_CHOICES = ( (True, 'فعال'), (False, 'غیرفعال'), ) class AvailableDates(models.Model): free_date = jmodels.jDateField(null=True, verbose_name="تاریخ فعال",) status = models.BooleanField(choices=AVAILABLE_DATE_CHOICES,null=True,default=True, verbose_name="وضعیت",) class Meta: verbose_name_plural = "روزهای فعال" verbose_name = "روز فعال" ordering = ['-free_date'] def __str__(self): return f'{str(self.free_date)}' class AvailableHours(models.Model): free_date = models.ForeignKey(AvailableDates,verbose_name="تاریخ فعال", null=True, blank=True,on_delete=models.DO_NOTHING,related_name='freedate') free_hours_from = models.IntegerField(null=True, blank=True, verbose_name="از ساعت",) free_hours_to = models.IntegerField(null=True, blank=True, verbose_name="الی ساعت",) status = models.BooleanField(null=True,default=True, verbose_name="آزاد است؟",) class Meta: verbose_name_plural = "سانس ها" verbose_name = "سانس" def __str__(self): return f'{str(self.free_date)} - {self.free_hours_from} الی {self.free_hours_to}' class Bookings(models.Model): user = models.ForeignKey(User,on_delete=models.DO_NOTHING, null=True, verbose_name="کاربر",) booker_name = models.CharField(max_length=100, null=True, verbose_name="نام",) booker_service = models.ForeignKey(BarberServices, null=True, on_delete=models.DO_NOTHING, verbose_name='خدمات') booked_date = models.ForeignKey(AvailableDates, null=True, on_delete=models.DO_NOTHING,related_name='booked_date', verbose_name="روز",) booked_time = …
