why model attribut is necessary for update view but not create view?
here in the below code in the CreateView theres no mention of model , but since we have mentioned form_class it automatically uses the model class mentioned in the form_class which is Book.but why doesnt it do same with the Update view . in UpdateView if i remove the model attribute it gives error: UpdateBook is missing a QuerySet. Define UpdateBook.model, UpdateBook.queryset, or override UpdateBook.get_queryset(). required code: models.py: class Book(models.Model): name = models.CharField(max_length=50) picture = models.ImageField() author = models.CharField(max_length=30, default="Anonymous") email = models.EmailField(blank=True) describe = models.TextField(default="Good Book") def __str__(self): return self.name views.py: class Upload(CreateView): form_class = BookCreate template_name = "libraryapp/upload_form.html" success_url = reverse_lazy('libraryapp:index') class UpdateBook(UpdateView): model=Book form_class = BookCreate template_name = "libraryapp/upload_form.html" success_url = reverse_lazy('libraryapp:index') -
Linking enum values when used in Django choices
I'm writing a Django web app to allow doctors to manage their pending licenses, certifications, and access to scientific journals in one dashboard. I've created a model JournalEntry that represents information shown on the dashboard about a journal they are subscribed to, with information like renewal date and subscription type built into the model. It is the case that there are certain choices for journal name, so the name field on the JournalEntry model is a CharField: class JournalEntry(models.Model): name = models.CharField( null=False, choices=JOURNAL_NAME_CHOICES, max_length=256) renewal_date = models.DateField( verbose_name="Date of Renewal", auto_now=False, auto_now_add=False, blank=True, null=True, ) sub_cost = models.FloatField( blank=True, null=False, max_length=6, verbose_name='Subscription Cost', ) icon_link = models.CharField( null=True, max_length=1024, blank=True) with the choices defined in an enum at the top like this: JOURNAL_NAME_CHOICES = [ ('NEJM', 'New England Journal of Medicine'), ('JVS', 'Journal of Vascular Surgery'), ] I want to have an icon image associated with each journal we allow for (eg the logo of the New England Journal of Medicine should show up next to the name on the entry on the dashboard), but I'm not sure how I can get the logo image url (say, a google images link) to be associated with the Journal name such … -

Django Modelform does not save TimeField to database
Hi i am creating a ModelForm where a user can enter a date and it gets saved to the database. Although the form is submitted successfully and the Charfield is saved to the database my Timefield object does not get saved. This is what the admin page looks like for me My models.py: from django.db import models # Create your models here. class GameSession(models.Model): gamechoices=[ ('seasons', 'Seasons'), ('proclubs', 'Proclubs'), ] game_choice=models.CharField(max_length=50, choices=gamechoices, default=None) time=models.TimeField() my forms.py from django import forms from .models import GameSession class CreateGameForm(forms.ModelForm): class Meta: model=GameSession fields=['game_choice', 'time'] my views.py from django.shortcuts import render, redirect from django.contrib.auth.decorators import login_required from .forms import CreateGameForm # Create your views here. @login_required def create_game(request): if request.method=="POST": form=CreateGameForm(request.POST) if form.is_valid(): form.save() return redirect('create-game') else: form=CreateGameForm() context={ 'form':form } return render(request, 'games/create_game.html', context) Also, right now models.TimeField shows up in the browser as a text input.

Proper way of doing Geolocations using GeoIP inside a Celery task
So, I have a Django middleware calling a Celery task. This task queries the GeoIP2 database to geolocate the given IP address and perform some additional processing. In the simplified form, the celery task looks like this: @shared_task(bind=True) def dump_json_logs(self, data): g = GeoIP2() location = g.city(data["ip_address"]) # some other code... The thing is, this celery task may be called thousands of times a second, which will cause the g = GeoIP2() client to be initialized every time the task is processed. Can I move this statement outside the function so that the client is initialized only once and then passed to each task? Where should I move it to in this case? -
How do I trigger a Celery task from Django admin?

Perhaps it was deleted? -

Modify datetime value in result of F() expression
I am trying to modify datetime value while making filter. I need to make each scheduled_for value to 02:00 AM next day and compare this date to other field. So at first I add 1 day with timedelta(days=1) and then in annotation I try to replace hours and minutes: bookings = Booking.objects.filter( cancel_time__isnull=False ).annotate( invoice_date=ExpressionWrapper((F('scheduled_for') + timedelta(days=1)), output_field=models.DateTimeField()) ).annotate( invoice_time=F('invoice_date').replace(hour=2, minute=0, second=0, microsecond=0) ).filter(invoice_time__gte=F('cancel_time')) But that thing doesn't work and I got error: AttributeError: 'F' object has no attribute 'replace' Is there any way to accomplish what I am trying to do? P.S.: Also I am not sure should I use DurationField or DateTimeField as output_field in ExpressionWrapper. -

Source page instead of page and wrong validation

Django admin template: what is base_site.html
I am currently customizing the admin templates and this makes me wonders that what is the usage/purpose of base_site.html? I understand that base_site.html extends from base.html but from the original code itself, it only adds HTML content for branding and title blocks. Hence, if I'm overriding the whole base.html, I can just add HTML content for branding and title blocks in base.html and empty the base_site.html. Please correct me if I am wrong. Thank you -
