Using threading.local() in a kubernetes container
I have a middleware in my app that sets the currently logged in user. On my local machine, get_current_user() works fine, but it seems to return None when the app is run in a kubernetes container.

Get updated session data in a Django Channels' consumer
Django Channels documentation says the following regarding session persistence: If you are in a WebSocket consumer, however, the session is populated but will never be saved automatically - you must call scope["session"].save() However, I noticed that it doesn't work the other way aroung, e.g. if session data gets modified by a view, those changes don't affect the version of the session state accessible from inside a consumer (even with request.session.modified = True applied) -

Django Flutter Ecommerce Shopping Cart
I am attempting to build an ecommerce site with a functional shopping cart that does not require a user to login before adding/removing items. To add this functionality I plan to store information based around the user's device to remember their order history, current items in cart, etc. For this, I am using a python Django backend (Django Rest Framework) and a Dart Flutter front end. This is going to be solely a web application to start and then cross into a mobile application, hence why I am using flutter. My question is more of a general architecture question rather than specific coding. I have done a lot of research as to how to grab a device ID using the flutter front end and then send that device ID to the backend Django application through a cookie. My question is if this is the right direction to go? Do I use flutter to create the cookie and then send it via POST request to the backend to manage the shopping cart? Or do I create the device ID through django backend some how? Any help would be appreciated. Thanks. -

How to set up a callable for Django Imagefield's >> default << parameter
So I have a Model that contains a couple hundred instances and I now added an imagefield logo. As I don't want to upload each and every logo via the admin manually, I want to set up a callable that returns the correct file path so I can just push all logos to media/company_logos. # models.py def logo_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> return f'company_logos/{instance.symbol}' class Company(models.Model): symbol = models.CharField(max_length=50) logo = models.ImageField(upload_to='company_logos/', default=logo_directory_path(instance=symbol, filename=f'{symbol}.png')) This returns an error at instance=symbol saying Type 'str' doesn't have expected attribute 'symbol' Another approach was logo = models.ImageField(upload_to='company_logos/', default=f'company_logos/{symbol}') which returns a URL as src="/media/company_logos/<django.db.models.fields.CharField>" I am not quiet sure how to set this up as I cant fully understand the official docs. My desired outcome is to have a URL for default like so: company_logos/IBM.png with field symbol being the corresponding part (I tried it via f-string). -

How save edit form in multilanguage project
I'm studying Django from the book Django 2 by Examples. I'm trying to improve a project which starts in chapter 10. Now, I'm trying to add multilingualism with the help of "django-parler". In general I did it, but it seems to me that there are better ways. Views are implemented as classes that are inherited from mixins. If a language other than the default language is selected on the page, the form still comes with the value of laguage_code field equal to default. I tried unsuccessfully to change this field in the form_valid method. The form was still saved with the default language. The only option that works for me is this, by it looks like kludge: def form_valid(self, form): language = translation.get_language() _course = form.save(commit=False) try: course = Course.objects.get(pk=_course.id) except Course.DoesNotExist: course = Course() course.owner = self.request.user course.set_current_language(language) cd = form.cleaned_data course.subject = cd['subject'] course.title = cd['title'] course.slug = cd['slug'] course.overview = cd['overview'] course.save() return redirect(reverse('courses:manage_list')) Maybe someone knows a more elegant way to implement this? I will be grateful. -

Django View Not Being Called from Template Form
This is my first time using Django (and I'm a beginner in web development in general), so I'm making a very simple project. It's a "daily check-in" app, where every day I click a button to check in, and I can view the history to see days I checked in or missed. The page is very minimal right now: My problem is I can't get the buttons to connect to their functions. Following along the official documentation, my current understanding is that the Django way to handle input is to wrap elements in a <form> that POSTs to a view, which is mapped in urls.py. Snippet of home.html: <div id="buttons-container"> <form action="{% url 'checkin-checkin' %}" method="post" style="display: inline;"> {% csrf_token %} <input type="button" value="Check in"> </form> <form action="{% url 'checkin-history' %}" method="post" style="display: inline;"> {% csrf_token %} <input type="button" value="View history"> </form> </div> Snippet of views.py: def home(request: HttpRequest) -> HttpResponse: # query DB to see if user is checked in... checked_in = True # hard-coded for now return render(request, "checkin/home.html", context={ "title": "Daily Check-in", "checked_in": checked_in, }) def checkin(request: HttpRequest) -> HttpResponse: print("called checkin") return home(request) # temp, just to return something def history(request: HttpRequest) -> HttpResponse: print("called history") … -

Handle HEAD request method using gunicorn and django

Get gzip file from endpoint, extract data and add to database improvements
I currently have a script that fires a request to an API endpoint which returns a csv.gzip file - which roughly contains 75,000 rows and 15 columns. I download this files to the webserver disk storage, unzip the file to .csv and then loop through every row and add the data into my database. Finally deleting the files saved to disk. The process currently takes between 5 and 10 minutes to complete. I'm sure there is areas of improvement but not sure how to implement them. Some of them is: Save csv data to variable rather than on disk. Bulk import the data into my database. I'm sure there are other improvements to be made, so any advice would be appreciated. response = oauth.get(realm) content = ET.fromstring(response.content) coded_string = (content.find('.//pricefile')) decoded_string = base64.b64decode(coded_string.text) with open('test.csv.gzip', 'wb') as f: f.write(decoded_string) with gzip.open('test.csv.gzip', 'rb') as f_in: with open('test.csv', 'wb') as f_out: shutil.copyfileobj(f_in, f_out) with open('test.csv') as f: reader = csv.reader(f) next(reader) for row in reader: pricing.objects.update_or_create( product_id=row[0], date=datetime.now(), defaults={ 'average_price': Decimal(row[1] or 0), 'low_price': Decimal(row[2] or 0), 'high_price': Decimal(row[3] or 0), ... }) os.remove('test.csv') os.remove('test.csv.gzip') -

If anyone can help it would be appreciated. for(let i = 0; i < 1; i++) { Array.prototype.zip = function (other, reduce, thisArg) { var i, result = [], args, isfunc = typeof reduce == "function", l = Math.max(this.length, other.length); for (i = 0; i < l; i++) { args = [this[i], other[i]]; result.push(isfunc ? reduce.apply(thisArg, args) : args); } return result; } const debt_outstanding = Array.from(document.querySelectorAll('.debt-outstanding-data')) const total_assets = Array.from(document.querySelectorAll('.total-assets-data')) const A = total_assets.map((element) => element.innerText) const B = debt_outstanding.map((element) => element.innerText) const C = A.zip(B, function (l, r) { return (l / (l - r)) - 1; }); var result = C.reduce(function (agg, item) { var key = "other"; if (item < .25) key = "0<0.25"; if (item > .26 && item < .50) key = "0.26<.50"; if (item > .51 && item < .75) key = "0.51<.75"; if (item > .76 && item < 1) key = "0.76<1"; if (item > 1.01 && item < 1.5) key = "1.01<1.5"; if (item > … -

Django & Celery: How to start a thread in AppConfig() only once?
I have a Django app iot_app with Celery and Rabbitmq, where in an app called app_users a thread is started in AppConfig(): app_users/apps.py: def start_test_thread(): th = Thread(target=mqtt_test_function, args=(), daemon=True) th.start() class AppUsersConfig(AppConfig): default_auto_field = "django.db.models.BigAutoField" name = "app_users" def ready(self): run_once = os.environ.get('CMDLINERUNNER_RUN_ONCE') print(run_once) if run_once is not None: return os.environ['CMDLINERUNNER_RUN_ONCE'] = 'True' start_test_thread() As you can see, I check if an environment variable is set to start the thread only once. This works. The thread is started only once. The problem is that when I start Celery with the command celery -A iot_app worker -l info, the thread is started twice. How can I make the thread start only once even with Celery?
