How to write a Case() SQL expression with an aggregated field (Sum) using Django's query builder
I am trying to recreate this SQL statement using Django's query builder: CASE WHEN sum(imps) = 0 THEN NULL ELSE SUM(total_expenses) / (sum(imps) / 1000) END as "cpm" I have tried: MyModel.objects.annotate( cpm=Case( When( Sum("imps")>0, then=Sum("total_expenses") / Sum("imps"), ), default=0, output_field=FloatField(), ) ) However it doesn't work because of this TypeError '>' not supported between instances of 'Sum' and 'int'. If there was a field lookup that enabled me to do total_imps__sum__gt=0, I am sure that would solve the problem. Note: Adding Sum("imps") as an annotation (total_imps=Sum("imps")) and doing total_imps__gt=0 works but it is not an ideal solution as I would have to create multiple annotations for fields I won't need. -
Postgresql SELECT optimisation into Django ORM
Please see below a PostgreSQL SELECT statement. This presently returns around 300k rows, which is the grouped result of several million underlying rows. The dataset is only going to get larger. Using the ANALYSE EXPLAIN function the cost of this select is 111847 units. This select statement is being used in a Django ORM query set model. So the results are queried and mapped into an object. Due to the time taken for the SELECT to complete my Django application is timing out. The underlying data is made of up daily times series data, but I don't need the whole history. I am using the dataset for current day, MTD, QTD, YTD, ITD grouped values. How can I optimise this? I have been investigating indexing but am struggling to apply here. Or should I just try and re-structure the whole query? Or even build other tables to hold the aggregated results for my Django ORM to call? SELECT customers_data.position_date, customers_data.code_id, customers_data.book_id, customers_data.base_lmv, book_tags.book, book_tags.market, book_tags.employee, pnl_data.base_daily_pnl, disasters_data.disaster_5_pnl FROM ( SELECT daily_customers_holding_scenario.code_id, daily_customers_holding_scenario.position_date, daily_customers_holding_scenario.book_id, sum(daily_customers_holding_scenario.base_lmv) AS base_lmv FROM daily_customers_holding_scenario GROUP BY daily_customers_holding_scenario.position_date, daily_customers_holding_scenario.code_id, daily_customers_holding_scenario.book_id) customers_data LEFT JOIN book_tags ON customers_data.book_id = book_tags.book_id FULL JOIN ( SELECT products.position_date, products.code_id, products.book_id, sum(products.palliser_base_pnl) AS … -
I need help to solve this
I'm encountering an issue with one of my Django views, and I'm hoping someone can help me troubleshoot it. When I try to access the URL: https://tout-talent.com/forfait/, the browser or site displays a different page with the message: {"success": false, "message": "Invalid request method"} However, on my server and in the debug.log file, I see the following log entry: "GET /forfait/ HTTP/1.1" 200 indicating a 200 OK HTTP status code. But the template that should normally display is not being rendered. Here's the code for the view : @login_required def subscribe(request): if not hasattr(request.user, 'company'): print("Utilisateur non connecté ou sans compagnie associée.") return redirect('login') # Or show an appropriate message company = request.user.company print(f"Company: {company}") active_subscription = None try: active_subscription = CompanySubscription.objects.get(company=company, is_active=True) print(f"Active subscription found: {active_subscription}") except CompanySubscription.DoesNotExist: print("No active subscription found.") if request.method == 'POST': form = SubscriptionForm(request.POST) if form.is_valid(): plan = form.cleaned_data['plan'] print(f"Selected plan: {plan}") if plan.name == 'lite': print("Redirecting to Lite plan duration view.") return redirect('days_duration_for_lite_plan', plan_ref=plan.ref) else: days = plan.duration_days amount = plan.price_per_month if days >= 30 else plan.price_per_day * days print(f"Days: {days}, Amount: {amount}") if plan.name == 'free': subscription, created = CompanySubscription.objects.get_or_create( company=company, defaults={ 'plan': plan, 'start_date': timezone.now(), 'end_date': timezone.now() + timedelta(days=days), 'is_active': True, … -
How to access set of objects in reverse Foreign Key in Django
I have 2 tables defined like this: class Optimization(BaseModel): name = models.TextField(unique=True, null=False) is_active = models.BooleanField(null=False, default=True) class Meta: db_table = 'optimization' class OptimizationInput(BaseModel): name = models.TextField(null=False) optimization = models.ForeignKey(Optimization, null=False, on_delete=models.CASCADE) class Meta: db_table = 'optimization_input' I want to get some Optimizations with their inputs.

Adding a filter to a Django Module
I'm working in a Django project. I've created a model to save the last 50 errors that happen. models.py class Error(models.Model): ERROR_TYPE_CHOICES = [ ('ERROR', 'ERROR'), ('WARNING', 'WARNING'), ] user_mail = models.CharField(max_length=500, blank=True, null=True) error_type = models.CharField(max_length=7, choices=ERROR_TYPE_CHOICES) error_message = models.CharField(max_length=1000, blank=True, null=True) error_message_detail = models.CharField(max_length=500, blank=True, null=True) created_at = models.DateTimeField(default=timezone.now) # Static field for maximum errors limit max_errors = 50 def __str__(self): return f"{self.error_type}: {self.error_message}" class Meta: ordering = ['-created_at'] # Order by descending creation date @classmethod def check_and_trim(cls): # # Obtain all errors ordered by creation date errors = cls.objects.all().order_by('-created_at') # If there are more than 50 errors, delete the older ones if errors.count() > cls.max_errors: errors_to_delete = errors[cls.max_errors:] for error in errors_to_delete: error.delete() admin.py class ErrorAdmin(admin.ModelAdmin): list_display = ('user_mail', 'error_type', 'error_message', 'error_message_detail', 'created_at') admin.site.register(Error, ErrorAdmin) So as you can see when there are more than 50 errors the oldest one is erased so that the new one can be saved. In the future maybe is needed to be saved more than 50 errors, so instead of changing the code I'd like to add a feature now so in the localhost:8000/admin/Error you can input how many errors you want to be saved. -

Using structlog with Datadog
We're using the logging module from the stdlib to send logs from our Django app to Datadog and we have customised our logging based on django-datadog-logger We're exploring a move to structlog, and I was wondering if there is a package that gives a good starting point to get log formatted for Datadog, similar to what the above library does as Datadog expects a few top level keys. Has anyone built something reusable already? Is there a recipe that we could reuse? PS: I already found the structlog Django extension, my question is more around formatting for Datadog -
What is the best approach to handle class instances in django application in a production environment?
I would like to consider 2 approaches. First, you could create a class and its instance in a class and inside views import the instance and call its methods. Second, you import the class and create instance of the class inside the view function when you handle a request. which one do you think is better. Also I am not saying about any class like , models, forms or serializer etc that are related to Django , but the ones I manually create for myself. Approach 1: Create an instance at module level and import it # utils.py class Calc: def run(self): # perform calculations return result calc_instance = Calc() # views.py from utils import calc_instance def view_function(request): result = calc_instance.run() # rest of the view logic Approach 2: Import the class and create an instance inside the view function # utils.py class Calc: def run(self): # perform calculations return result # views.py from utils import Calc def view_function(request): calc_instance = Calc() result = calc_instance.run() # rest of the view logic Also, I see Approach 1 creates a single instance that remains in memory for the lifetime of the process, at least in the development server.

whitenoise module not found in production
Error: I ran into this error when trying to deploy my Django app using GAE: ModuleNotFoundError: No module named 'whitenoise'. The error occurs when starting the wsgi application. Attempted fixes: Wrapping the wsgi in whitenoise as mentioned here was done, (https://whitenoise.readthedocs.io/en/stable/index.html#quickstart-for-django-apps) but it didn't make a difference. whitenoise 6.7.0 is downloaded and is in requirements.txt, and the necessary whitenoise middleware is in settings.py.

Django - dropdown (select widget) in form is not saving data to db
I'm using this form to get a dropdown menu in my html form : forms.py class forms_bdc(forms.ModelForm): [...] bdc_description_1 = forms.ModelChoiceField(required=False,queryset=models_products.objects.values_list('product_denomination', flat=True), widget=forms.Select(attrs={'id': 'editable-select-2','onchange': 'populate_selected_product(this.id)'}),empty_label=None ) models.py class models_bdc(models.Model): [...] bdc_description_1 = models.CharField(max_length=50) But when I save / submit the form, the data are not saving into the database. If I remove the select widget to a regular forms.charfield, the datas are saving correctly. So I assume the mistake is the forms.py but I can't see where. Thanks -
Frequent Deletion Failures in Django with CockroachDB
I'm using CockroachDb (version 24.2) with Django (version 5.0.7) but im currently running into an issue I don't really understand. When I trigger a certain view many times in a row which will delete an object from the Cockroach Database, it maybe works for like 4 out of 6 object I requested a deletion for, meaning 2 object will stay undeleted, I dont get any Error or stacktrace at all, the transaction simply does not get trough while Django reports back that everything went fine. The view can be very simple, like below.: @api_view(['DELETE']) @authentication_classes([]) @permission_classes([IsAuthenticated]) def delete_my_model_entry(request, pk): try: # Fetch the object to be deleted my_model_entry = MyModel.objects.get(pk=pk) # Delete the object my_model_entry.delete() return Response(status=status.HTTP_204_NO_CONTENT) except ObjectDoesNotExist: return Response({'error': 'Object not found'}, status=status.HTTP_404_NOT_FOUND) except Exception as e: return Response({'error': str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) But if I fire against it many times in a short timeframe, the deletion actually dont happen at all ... For the moment I'm was not able to isolate the actual issue here I simply use django-cockroachdb==5.0 and psycopg2==2.9.9, exactly like described in the Readme file of the libraries. Thank in advance. -

Django/Python - How to assign a file path variable in a platform-independent way?
I have a Django project where one of the .env file variables is going to represent an absolute file path. E.g., DEBUG=True SECRET_KEY='blah_blah_blah' MY_STORAGE_PATH = 'D:\\files\\for\\my\\project' Obviously the above would work fine on a Windows machine with a D: drive, but it's no good if there's no D: drive or if the machine is using some other OS. Now I can think of any number of functioning ways to supply this .env string in a platform-independent way, and then use string manipulation and the os.path methods to assemble the actual path. I could break out the drive & path separately, using a 'neutral' path separator of my own choosing: MY_STORAGE_DRIVE_FOR_WIN = 'D:' MY_STORAGE_PATH = '|files|for|my|project' ...I could supply the configuration formatted as a list, convert it to a real list, then feed into os.path.join(): MY_STORAGE_PATH_ELEMENTS = '["files","for","my","project"]' ...and so on, and so on. But before I go roll my own that way, I wanted to know: is there some accepted convention for this kind of use case? (Surely this isn't the first time someone needed to provide an .env value to represent a platform-independent path?) -
