Need help running Django at a local machine after deploying it to DigitalOcean apps
I'm using Digital Ocean app platform to host my website but after following the settings from the end of this documentation from the website (at the end of step 2), there's something I think I'm missing cause I have deployed the app following the guide but now I can't run it on my local machine. The error comes from this snippet, throwing the Exception "DATABASE_URL environment variable not defined" elif len(sys.argv) > 0 and sys.argv[1] != 'collectstatic': if os.getenv("DATABASE_URL", None) is None: raise Exception("DATABASE_URL environment variable not defined") DATABASES = { "default": dj_database_url.parse(os.environ.get("DATABASE_URL")), } Any clue? I thought I should use something like python-dotenv or django-dotenv or having multiple Django settings modules, but my brain right now is just frosted. Please help -
Django ASGI/channels with Streaminghttpresponse
I add channels to my project and it's creating a problem, I have a stream func that streama video with streaminghttpresponse , and that work well before I add asgi/channels to run the server I saw that it's some bug that will be fixed in django 4.2 but I look for solution for now/ or if someone suggests another library for a socket that will now cause a similar problem this is my code Django v - 4.0 channels - 3.0.5 views.py def stream(source,startVideo): if startvideo : url = source + str('.mp4') cap = cv2.VideoCapture(url) while (cap.isOpened()): ret, frame = cap.read() if not ret: check = False break results = model(frame,augment=False,size=320) det = results.pred[0] results.render() annotator = Annotator(frame,line_width=2, pil=not ascii) im0 = annotator.result() image_bytes = cv2.imencode('.jpg', im0)[1].tobytes() yield (b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + image_bytes + b'\r\n') cap.release() cv2.destroyAllWindows() @csrf_exempt def video_feed(request): if request.method == 'POST': global startvideo,start,content startvideo=True content = request.GET.get('url','not') return StreamingHttpResponse(stream(content,startvideo), content_type='multipart/x-mixed-replace; boundary=frame') ASGI.PY application = ProtocolTypeRouter({ 'http': get_asgi_application(), 'websocket':AuthMiddlewareStack(URLRouter( webcam.routing.websocket_urlpatterns )) }) setting.py INSTALLED_APPS = [ 'channels', ......

Django form.instance.field displaying incorrect datetime value on HTML template despite having the correct value at hand
I'm running Django 4.1, and the view that serves the template is a FormView-child. To start off with, here's the canonical answer as to what the correct value is, taken directly from the database: In [6]: DCF.objects.last().appreciation_date Out[6]: datetime.date(2023, 1, 24) The first HTML template invocation of that same field: <h5>Title: {{ form.instance.appreciation_date }}</h5> And the result is as expected: About 30 lines of code below (none of which do anything particularly functional, it's just a boatload of div declarations for CSS and styling), inside a <form>, on a modal: <div class="mb-3"> <label for="{{ form.appreciation_date.id_for_label }}">Date</label> <input class="form-control datepicker" placeholder="Please select date" type="text" onfocus="focused(this)" onfocusout="defocused(this)" name="{{ form.appreciation_date.name }}" value="{{ form.instance.appreciation_date }}"> </div> And now, prepare for the result - which also highlights the question I am about to get to: What in Django's ghost in the shell is going on? How did 2023-01-24 become 2023-01-01 for no apparent reason? Or said differently, why and how can the same context invocation have two different values in the same render of the same template? I would very much like for the second invocation to show the correct value - meaning the value that is both in the database, and presumably also in … -

datetime.datetime.now() is five minutes off
I'm currently developing a django backend. I use auto_now_add=True in my model to populate a start point on create(). I use datetime.datetime.now() to add an endpoint on update(). The entire code for that is datetime.datetime.now().replace(tzinfo=pytz.timezone(settings.TIME_ZONE). Here's an example for an instance that was created at 2023-01-21T19:26:04.561888Z and updated only seconds later. As you can see, the endpoint populated on update() is somehow before the startpoint, which is not intended behavior. Thank you -

In Django, is it possible to see which method is generating a SQL query?
When creating a custom User (inherits from AbstractUser) we have a signal which creates a randomized password (from Django's get_random_string) and send it out in an email in a celery task to the user: # signals.py @receiver(post_save, sender=User, dispatch_uid="c_employee") def create_employee(sender, instance: User, created, **kwargs): if not instance.has_usable_password(): password = get_random_string(length=12) email_args = { # we're collecting information for the celery task "password": password, } email_send_as_task.delay( email_args, "Sending PASSWORD CREATE email to {{ instance.email }}" ) if password: logger.debug(f"CREATE PASSWORD FOR INSTANCE: {instance}") sender.objects.filter(pk=instance.pk).update(password=make_password(password)) # .update so we don't trigger signal again And looking through my (logging level DEBUG) logs, I can see the following: D0121 18:55:35.434 accounts.signals:81 CREATE PASSWORD FOR INSTANCE: Employee @ Example D0121 18:55:35.641 django.db.backends:123 (0.000) UPDATE "accounts_user" SET "password" = 'pbkdf2_sha256$260000$FKRktQOZAwQ4OjcvD3QHGn$dmg9T1Y3mEwN1nbI5W2EyOAHp2chU4MGvSlaOTORNxY=' WHERE "accounts_user"."id" = 394; args=('pbkdf2_sha256$260000$FKRktQOZAwQ4OjcvD3QHGn$dmg9T1Y3mEwN1nbI5W2EyOAHp2chU4MGvSlaOTORNxY=', 394) So far so good.

Django third-party library views: determining async vs sync
I want to incorporate async into my Django library. If I have a Django library that has 1) a sync view and 2) a urls.py that points to that sync view, how do I support both sync and async? Presumably, I could ask the developer to set a setting to LIBRARY_ENABLE_ASYNC, then in views.py, I could write: from django.conf import settings if settings.LIBRARY_ENABLE_ASYNC async def view(request): pass else: def view(request): pass But that doesn't seem quite... right? Admitedly, I believe because we integrate with the Django ORM, we'll be splitting the views into two separate files/directories/and urls.py files, and the developer would simply include() the correct urls.py based on whether they're using ASGI/WSGI, but in the event the above does happen, is there a better way to determine whether a user is using ASGI/WSGI? -

Increment field value by 1 from the last value if a boolean field is checked - Django
I have a simple model of application: class Application_data(Models.model): application_sn=models.AutoField(primary_key=True) applicant_name=models.CharField(max_length=20) sanction_sn=models.IntegerField(default=0) is_sanctioned=models.BooleanField(default=False) In this model, I may have multiple applications, not sanctioned. I want that if I set is_sanctioned as true,sanction_sn gets incremented by 1, and for the next random row from the db, if I set the boolean as true, sanction_sn gets again incremented by 1, i.e. 2. And setting boolean as False should also decrease the values of sanction_sn, accordingly. For example: in a set of 130 rows, at 124th sanction_sn, I set the boolean as False, so 123 records before that particular record, have no effect at all but after 123, 125th record will have sanction_sn as 124 and 130th record will have sanction_sn as 129. -
