Django : automatic retry of failed database operations
Database operations can fail because of temporary network errors or because the database is temporarily unavailable. Is there a way to automatically retry the operation in these cases ? The documentation of Google's managed database offering states that connection pooling systems should reconnect to the database if a connection is in a bad state, and applications should retry a database transaction if an error app in the middle of a transaction. (See https://cloud.google.com/sql/docs/postgres/manage-connections, section "Exponential backoff") How can I implement this advise using Django? I'm currently having problems with views that successfully perform some database operations but randomly encounter a connection error during a subsequent database operation. How can I retry the database operation so that the view is finally rendered successfully? -
Status code 400 (Bad Request) with Django API tests
I'm working on a project with Django as framework and poetry as manager. Running some tests I found some problems with my viewsets, but I don't know exactly where it is.

Django - Naive datetime field to time zone
I'm using Django to build an web app and I have a shift in datetime datas when I upload them. In settings.py I specify : TIME_ZONE = 'CET' USE_TZ = True When I upload data like 29/01/2024 14:00:00 , I have this message : DateTimeField my_table.date received a naive datetime while time zone support is active In the PostgreSQL database, datas are stored in UTC not CET, in my example: 2024-01-29 13:00:00+00 Django interpret naive datetime in UTC not in CET (UTC+1) despite my settings.py TIME_ZONE parameter. How can I define that datas are CET and store 2024-01-29 13:00:00+01 ? -

cropping image only works by triggering second time save method
I have a django application. And I try to crop an high resolution image to a smaller resolution image. The problem I am facing is that cropping the image only works when the save method is triggered for the second time. So not the first time when I trigger the save method. So in models.py I have an image property: images = models.ImageField( upload_to="media/photos/animals", blank=True, null=True, verbose_name="Foto") And the save method looks like: def save(self, *args, **kwargs): self.slug = slugify(self.name) if self.pk is not None: orig = Animal.objects.get(pk=self.pk) if self.images: if orig.images != self.images: # Perform the crop if the image is updated with a different image im = Image.open(self.images) # To standardize your color space if not already RGB im = im.convert("RGB") exif = None if 'exif' in im.info: # Exif data records orientation, among other things exif = im.info['exif'] output = BytesIO() square = 200 # Set the dimension x_final, y_final = square, square # Get image dimensions width = im.size[0] height = im.size[1] if width > height: # crop the largest square out of the center of a landscape image and resize x1 = (float(width/2)-float(height/2)) y1 = (height - height) x2 = ((float(float(width/2)-float(height/2))) + height) y2 = … -
How to make a proxy model's relationships return proxy models themselves

Filter queryset based on values in the other queryset
I have the following model in django: class EmailSubscriber(BaseSubscriber): email = models.EmailField() name = models.CharField() Now let's say I made a queryset from EmailSubscriber Like below: queryset1 = EmailSubscriber.objects.all() Now I create another queryset like below: queryset2 = EmailSubscriber.objects.filter(some filters) I want to exclude those fields in queryset1 that have their email and name in queryset2. I mean, if a record in queryset1 has {"email": "john@gmail.com", "name": "john"} and there is a record in queryset2 with {"email": "john@gmail.com", "name": "john"}, the record in queryset1 must be excluded. So they must be unique together. How can I do that in an efficient way? Thanks in advance -

Why aren't the environment variables working inside my Django Docker container?

Skipping a step in a WizardView based on data entered in that step
I'm trying to build a formtools Wizard where a confirmation form is shown in one of the steps. The confirmation form is only show in specific cases (e.g. if a user has previously ordered the same item before), and it should no longer be shown after the user has confirmed. Basically, my code looks like this: def ask_confirmation(wizard): # Database conditions go here return user.has_ordered_same_item_before class ItemWizard(SessionWizardView): condition_dict = { "confirm": ask_confirmation, } ... Obviously, the step where the user is asked to confirm is never passed, because the condition is always True. I don't want to store the user's response in the database, it's just something that the wizard needs to "remember" and that I can check in the condition function. How can I test whether the user has confirmed and skip the form once they did? -

I have the setup below that I'm using to inject extra data from the request object into each log message and it works fine. I recently needed to import a urls.py file from another app into the auth_middleware.py file to check all registered DRF routes and redirect appropriately, but I immediately got ValueError: Unable to configure filter 'session_context' each time I attempt to start the application. The import statement that is triggering this error (called from auth_middleware.py) looks like this: from apps.app_name.api.urls import router proj/middleware/auth_middleware.py import threading local = threading.local() class CheckUserLogin: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): setattr(local, "uip", request.META.get("REMOTE_ADDR")) setattr(local, "sid", request.session.session_key or "n/a") if request.user.is_anonymous and request.path != reverse("auth_service_login"): # apply redirect login and send to url_login return HttpResponseRedirect(url_login) return self.get_response(request) services/log_ctx.py import logging from proj.middleware.auth_middleware import local class ExtraLogCtx(logging.Filter): def filter(self, record): defs = "n/a" record.uip = getattr(local, "uip", defs) record.sid = getattr(local, "sid", defs) return True proj/settings.py MIDDLEWARE = [ ...

"filters": ["session_context"], ... }, }, } I have __init__.py in the services and middleware folders and am unsure where else to look. Any … -
Stream Zeros with Django with StreamingHttpResponse
I have to send an amount of Zeros as response, defined by the request. They have to be plain zeros. (I know, a rather odd task...) so, for example, you need 100mb of zeros, you query ?size=100&unit=mb, you will get a stream of 100mb only zeros. Since it can be up to 16gb of zeros, I do not want to generate them at first, rather generate a stream of zeros and send this "line by line". This is what I came up with, but it does not behave like I want because it first gathers the full data and then sends it. class CreateImageAndResponseView(View): line_count = 0 def get(self, request): size_str = request.GET.get('size', '') unit = request.GET.get('unit', '').lower() if unit not in ('gb', 'mb'): return HttpResponse(status=400) try: size = float(size_str) if unit == 'gb': size_bytes = int(size * 1024**3) else: size_bytes = int(size * 1024**2) except ValueError: return HttpResponse(status=400) self.line_count = size_bytes // 1024 return StreamingHttpResponse((b'0' * 1024 for _ in range(0, self.line_count)), content_type='application/octet-stream',) I already saw Problem with Django StreamingHttpResponse, but I do not know which middleware could block this. Also, I am not running nginx or apache, just django from my console.
