Django sessions not saving data from form, no error or apparent reason
I have a view with different 'stages' (as I wanted to keep the same URL without resorting to something like AJAX), which takes data from a form, does some processing, and then would save that data to the database. Because I can't forward some data via POST, I wanted to save that data in a session. For some reason, this is not working - at all. I can see the data being extracted from the form, and I can forward that via POST, but attempting to save or retrieve it to a session either results in blank data, or a KeyError. This is the view I am using (very trimmed down, but the error is reproducible) def processpayment(request, *args, **kwargs): if request.method == 'POST': form = paymentDetailsForm(request.POST) amount = request.POST.get('amount', False); stage = request.POST.get('stage', False); if (stage == "checkout"): return render(request, "payment.html", {'form': form, 'amount': amount, 'stage': stage}) if (stage == "complete"): return render(request, "payment.html", {'amount': request.session['amount'], 'stage': stage, 'name': request.session['name']}) if (amount == "custom"): if form.is_valid(): amount = form_data.get('amount') name = form_data.get('name') request.session['amount'] = amount request.session['name'] = name request.session.modified = True return render(request, "payment.html", {'form': form, 'stage': stage, 'amount': amount}) return render(request, "payment.html", {'amount': amount, 'stage': stage}) else: return … -

HTML element src attributes sends concatenated string to server
I have a ReactJs and Django project setup. I send a GET request to my localhost for localhost/index, the server running my Django project returns index.html which is correct. The index.html has a html element with src value "asset/script.js". It sends a request to Locahost/index/asset/script.js instead of Localhost/asset/script.js.

How to get the date of last change from multiple Django models?
The environment is Django 4 and Python 3.10+. In the application there are multiple data models, each with 'created' and 'modified' DateTimeFields. I need to get the timestamp of last data modification - either creation of new object or modification of a existing one, for cache invalidation. Currently the code checks for the newest creation timestamp and is like this: from django.db.models import Max qs_1 = Model_1.objects.all() qs_2 = Model_2.objects.filter(active=True).order_by('created') qs_3 = Model_3.objects.filter(active=True).order_by('created') last = max(list((itertools.chain(list(queryset.aggregate(Max('created')).values()) for queryset in (qs_1, qs_2, qs_3) if queryset.count()))))[0] My questions are as follows: The expression to get the last creation date is quite convoluted. Is there a way to compute the latest timestamp over multiple models using the ORM alone? It can be done in pure SQL, so it should be possible in the ORM. How do I extend it to also compare the modified fields of the models? -

Django Forms two models with foreign key
I am trying to implement the booking function in my Django project. I have two models, one for the customer (Fordonsregister) and one for the service (FordonsService), a one to many relationship as one customer (ID is vehicle registration number: "regnr" which is the primary key in the customer model and the foreign key in the service model (code below). When a customer wants to book they click on a certain service (generated from the service types model (ServiceTypes, below) and get redirected by the urls.py to that specific service url. I would then like the customer to fill out only certain fields. The customer should only fill out the primary key, the foreign key in the form should be auto filled. the "typ" in the service model should be autto filled as the URL is different for the chosen service type. The models: from django.db import models # Create your models here. class Fordonsregister(models.Model): regnr = models.CharField(max_length=6, primary_key=True, null=False, blank=False) namn = models.CharField(max_length=255, null=True, blank=True) tel = models.CharField(max_length=255, default='070-000 00 00', null=True, blank=True) email = models.EmailField(null=True, blank=True) kund_sedan = models.DateTimeField(auto_now=True) kund_points = models.IntegerField(default=0) def __str__(self) -> str: return self.regnr class Meta: ordering = ['regnr'] verbose_name = 'Kunder' verbose_name_plural = … -
