What is wrong with this django view?
in this django view I'm trying to do the following: Check if there is a "chartentry" with today's date In that case, do not substitute the description with the new value, but just append it to the old value I can't for the life of me figure out why it is always repeating twice the new value (e.g. the description ends up as "newvalue;newvalue" instead of "oldvalue;newvalue" Help appreciated @login_required def chartentry_create(request, chart_id): obj = get_object_or_404(Chart, id=chart_id) todaysentry = obj.chartentries.filter( created_at__gte=timezone.now().replace(hour=0, minute=0, second=0), created_at__lte=timezone.now().replace(hour=23, minute=59, second=59), ).first() # if it's today's entry, append data to it instead of creating a new one if todaysentry: form = ChartEntryForm(request.POST, instance=todaysentry) else: form = ChartEntryForm(request.POST or None) if form.is_valid(): # if it's today's entry, append description if todaysentry: form.instance.description = ( todaysentry.description + ";" + request.POST["description"] ) form.instance.chart = obj form.save() messages.success(request, "Entry updated successfully") else: for error in form.errors: messages.error(request, form.errors[error]) if is_ajax(request): context = {"chart": obj} return render(request, "chart_entries_by_patient_partial.html", context) else: return redirect("chart-detail", patient_id=obj.patient.id) -
Could not find 'price' in DJ4E assignment
I've got a problem with DJ4E course by dr.Chuck.

Django for loop with parentheses for zip command
In Python this code works mylist1 = ["peru", "germany", "japan"] mylist2 = [["lima","cusco"], ["berlin","munich"], ["tokyo"]] mylist3 = [[1,2], [3,4], [5]] for country, (cities, numbers) in zip(mylist1, zip(mylist2, mylist3)): print(country) for city, number in zip(cities, numbers): print(city) print(number) I'm able to print what I want: peru lima 1 cusco 2 germany berlin 3 munich 4 japan tokyo 5 However in Django I have an issue with the parenthesis. In views.py I can set mylist=zip(mylist1, zip(mylist2, mylist3)), so I will have {% for country, (cities, numbers) in mylist %}: print(country) {% for city, number in zip(cities, numbers) %}: print(city) print(number) The first for loop is where I'm stuck. what should I do to use (cities,numbers). I think parenthesis is not accepted. python approach doesn't work -
Offcanvas dismiss button does not work when instance initialised via Javascript
I have offcanvas as part of the page layout. It does not show by default, but I want it to always show on large screens. On small screens it should have a button to dismiss it. Another button to show the offcanvas is placed on the menu panel underneath it. I'm using JavaScript on page load and on page resize to show the offcanvas when if screen is large. If the user then scales the screen down, the offcanvas should remain visible until dismissed. The issue is that the dismiss button works on the offcanvas only if it has not been initialised via JS. I.e. if opened on a small screen, the offcanvas is not visible and the two bottons can be used to toggle back and forth. But once the offcanvas has been triggerd via JS on a large screen, the dismiss button no longer works when the screen is downsized. I'm struggling to figure out if it has lost an EventListener and how to add it back, if so. Layout: <!-- Button to show offcanvas (positioned underneath it) --> <div> <button class="btn" type="button" id="off-canvas-body-toggle" data-bs-toggle="offcanvas" data-bs-target="#floating-menu"> <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" fill="#422543" class="bi bi-arrow-bar-right" viewBox="0 0 16 16"><path fill-rule="evenodd" … -
Why is this react-django app not rendering anything

Cannot visualize ImageField in Django Rest Framework
I have a model with an ImageField: image_url = models.ImageField(upload_to=upload_to, blank=True, null=True) I did include it in my serializer in this way: image_url = serializers.ImageField(required=False, use_url=True) This is my viewset: class ProductViewSet(viewsets.ModelViewSet): queryset = Product.objects.order_by('-id') serializer_class = ProductSerializer parser_classes = (MultiPartParser, FormParser) permission_classes = [ permissions.IsAuthenticatedOrReadOnly] def perform_create(self, serializer): serializer.save() The media root and url: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' My urls.py: urlpatterns = [ path("users/", include("user.urls")), path("products/", include("products.urls")), path("utils/", include("utils.urls")), path("auth/", include("djoser.urls")), path("auth/", include("djoser.urls.jwt")), path("graphql/", csrf_exempt(GraphQLView.as_view(schema=schema, graphiql=True))), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) It get listed properly: But the problem is that once I click on the url of the image (that is inside the media folder), it shows me a 404 error in this url: http://127.0.0.1:8000/media/images/base_bWxtftQ.png.

Creating A Responsive / Dynamic Form for Business Users, Efficiently
I am a data engineer and I've found myself in a position of needing to develop advanced frontend forms for nontechnical business users. These business users do not want or need to understand complexities of data modeling, and this is my strategy to try and remove the manner by which the complexities of data modeling impact the data entry process. As I said though, I am a data engineer- not a web developer. Before I reinvent the wheel here, what would be some feedback for this approach? Form Components and Their Expected Behaviors: Selection Fields: Behavior: Prepopulated with unique values from a column, allowing users to select or search for an option. Initialization: Start as empty fields. Input Fields: Behavior: Accept raw input from the user. Update Fields: Behavior: Corresponds to a table column that should receive updates. Also listens to a single Invisible Field for state changes. Visibility: Not editable until their corresponding Invisible Field is populated with a row-id value. Edit State: Require a double-click to enter an editable state. Value Update: Leaving the editable state with a changed value results in an UPDATE to the database record matching the ID value in the corresponding invisible field. Invisible … -
UserAccountManager superuser not loggin in
I am trying to add to my UserAccountManager, a way of creating a superuser so that I can easily manage my database, my problem is that when I create the super user from the terminal, everything seems ok, I don't get errors, but when I try to log in the default django admin page, it says that no staff account with those credentials is found. I have tried deleting my database, removing and redoing migrations. This is my models.py class UserAccountManager(BaseUserManager): def create_user(self, email, first_name, last_name, password=None, **extra_fields): if not email: raise ValueError('User must have an email') email = self.normalize_email(email) user = self.model(email=email, first_name=first_name, last_name=last_name, **extra_fields) user.set_password(password) user.save() return user def create_superuser(self, email, first_name, last_name, password=None, **extra_fields): extra_fields.setdefault('is_staff', True) extra_fields.setdefault('is_superuser', True) return self.create_user(email, password, first_name, last_name, **extra_fields) class UserAccount(AbstractBaseUser, PermissionsMixin): email = models.EmailField(max_length=255, unique=True) first_name = models.CharField(max_length=64) last_name = models.CharField(max_length=128) is_active = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) objects = UserAccountManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['first_name', 'last_name'] -
Daphne refuses to connect websocket requests
I have a developed a complex Django server consisting of several applications, making use of channels in combination with the Daphne server an reverse proxy uplink from Nginx. This is the site configuration from /etc/nginx/sites-available: server { listen 80; server_name django.mydomain.eu; return 301 https://$server_name$request_uri; } server { client_max_body_size 100M; listen 443 ssl; server_name django.mydomain.eu; ssl_certificate /etc/letsencrypt/live/django.mydomain.eu/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/django.mydomain.eu/privkey.pem; access_log /var/log/nginx/django.mydomain.eu.access.log combined; error_log /var/log/nginx/django.mydomain.eu.error.log info; location /ws/ { proxy_pass http://127.0.0.1:8000/ws/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; } location / { proxy_pass http://127.0.0.1:8000/; } } Both HTTP and Websocket requests are forwarded to Daphne on port 8000.

Django Container Fails to Find Settings Module Specified in Environment Variable
I'm encountering a persistent issue when deploying my Django application using Docker. Despite specifying the settings module in my environment variable, Django throws an OSError indicating it cannot find the file. Here's the error I'm getting: OSError: No such file: /code/app/settings/environments/.py This suggests that Django is looking for a .py file without a preceding filename in the /code/app/settings/environments/ directory.
