Nginx service of type LoadBalancer vs ingress (using nginx-ingress) vs ingress + nginx service of type ClusterIP
We are moving from standalone docker containers architecture to K3s architecture. The current architecture uses a Nginx container to expose multiple uwsgi and websocket services (for django). I'm reading conflicting opinions on the internet over what approach should be used. The options are: Nginx service of type LoadBalancer (Most conf from existing architecture can be reused) Nginx-ingress (All conf from existing architecture will have to be converted to ingress annotations and ConfigMap) Nginx-ingress + nginx service of type ClusterIP (Most conf from existing architecture can be reused, traffic coming into ingress will simply be routed to nginx service) -
Filter objects based on token expiry date and user date_joined using Q and "gt" Django
I want to delete users that haven't activated their accounts when the activation token have expired, activation token expires after 30 minutes. from django.db.models.functions import Now def delete_unactivated_users(): User = get_user_model() expiry = User.date_joined + timedelta(seconds=1800) unactivated_users = User.objects.filter(Q(Now()__gt=expiry) & (Q(is_active = False))) for user in unactivated_users: user.delete() print('<<<User Deleted>>>') user.save I am getting a syntax error on line 5 of the code, I tried using unactivated_users = User.objects.filter(Q(expiry__lt=Now()) & (Q(is_active=False))) but it didn't result in the same meaning. The problem seems to be the placing of Now() and expiry on line 5 -
How we can get the updated data by refreshing the cache using the cache_page in DRF with the same route?
The website is similar in functionality to Twitter and we're using a Django caching mechanism for the feed but when the user created his post he is not able to find his post for the next 10 minutes due to the caching and we want to show the latest results to the user so, how we can show the latest data to the user after creating his post using the same route Here is the urls.py code from django.views.decorators.cache import cache_page from . import views CACHE_TIME=60*10 urlpatterns = [ path('', cache_page(CACHE_TIME)(views.PostListAPIView.as_view()), name="post-list") ] if I call the API --> http://127.0.0.1:8000/v1/posts/ then data will be stored in the cache for the next 10 minutes but I want to refresh after the specific event so, how can I get the updated data before the 10 minutes also, I have found a solution for it if we pass http://127.0.0.1:8000/v1/posts/?{username}=true then we can get the latest data for the user but is there any other better approach or possibility to show the latest data? if yes, then please list the method and some details about it -

Multi screen user input in Django to create one composite order
I am designing a consumer app and I will be writing it in Django. What I would like to be able to do is over a series of templates/screens accept user input. The input from one screen will be relevant to subsequent screen and should be available to the javascript and html in these subsequent screens e.g. I have one lead screen where you choose a type of 1, 2 or 3 and depending on that the javascript on the following screen controls how many pins a user is allowed to drop on a map. At the end of the last user input screen I would like to create an order with a status of ‘payment pending’ with all of the user variables stored on it and then go to a payment screen, and if there is a successful payment set the order to a status of ‘ready to process’. I have looked at some video tutorials about building an e-commerce aplication and read some online resources and I wondered is a ‘context’ the way to do this of is another method such as a session variable or is there another recommended method. Also, is best practice to wait to … -
How to prevent data tampering when form is set as readonly with Django?
INTRO: I have a Django web app which does the following: Allows the user to fill the form After the form is submitted, it shows the form with the previously filled values In step 2, the form fields are set as read-only because they should not be modified. So in my views.py file I have the following information: def insert_data(request): # Get the form from a previous post request (coming from step1) form_one_item = ProductForm(request.POST, request.FILES) # Set the fields as readonly (this is step 2) form_one_item.fields['name'].widget.attrs['readonly'] = True return render(request, 'mypage.html', {'form_one_item':'form_one_item'}) The form therefore looks like this: and it is supposed to be resubmitted through another post request (I know it is confusing but I need to do so). PROBLEM: At first glance, it looks like it is all fine but then I noticed that I can right-click on the field and modify its content: As a matter of fact if I repost the readonly form, the value shown is modified according to what I write into the value field. QUESTION: Are you able to suggest a possible way to keep the readonly option but at the same time to avoid to pass a modified value once I … -

Scheduled tasks in Django to update data in the models (database)
I need to schedule tasks via Pythonanywhere, to update some records in my database. As an example, I do have Events as models: models.py class Events(models.Model): event_title = models.CharField(max_length=300) event_info = models.TextField(max_length=2000) event_date = models.DateField(default=now) event_time = models.TimeField(default='00:00') event_location = models.CharField(max_length=150) event_status = models.CharField(max_length=30, choices=EVENT_STATUS_CHOICES, default='New Event') Also within that Events class in models.py I have the following: def save(self, *args, **kwargs): if date.today() > self.event_date: self.event_status = 'Completed Event' super(Events, self).save(*args, **kwargs) Thanks to that, all events in the past, change their status to Completed. Problem is, you need to refresh the page to have the save function run on the production website. It also drives some other functions, e.g. showing the user the count of active events - this one as well, in order to show the right active number of events, has to be refreshed manually. By scheduling tasks in PA to run overnight, iterating through all Events, and if in the past, changing their status. I created the below file and uploaded it to PA Tasks. tasks.py from .models import Events from datetime import date def verify_events(): all_events = Events.objects.all() for event in all_events: if event.event_date < date.today(): event.event_status = 'Completed Event' event.save() I got an … -
Can i use both django autofield and foreignkey on one field?
so i have specific use case currently the database has a table with one field that acts as both primary key and foreign key (and i have no access to change this as it would break other processes) so what i tried with the models is something like this: class Foos(models.Model): foo_id = models.AutoField(primary_key=True) foo_name = models.CharField(max_length=15) foo_dt = models.DateTimeField() class Bars(models.Model): bar_id = models.AutoField(primary_key=True) bar_id = models.ForeignKey(Foos, db_column='bar_id', on_delete=models.CASCADE, blank=True, null=True, related_name='bars') bar_qty = models.IntegerField() bar_image = models.ImageField() That didn't work as django will keep the last bar_id (the foreignField) and ignore the AutoField, the thing is i need the foreign key to do some reverse lookup like Foos.object.values(bars__bar_qty) so i can get the left outer join query. But someone else need the AutoField. I know django is really strict on it but is there a possible solution? i just need to keep the reverse lookup i am fine with autofield if it is possible but the thing is django return an error not permitted. -
