How can I decrease the value of a field of a queryset simultaneously?
I want to make a site where people can make listings for things to sell. I want it to have a front page where the most popular (hot) items are always displayed. Popularity decreases with time and increases with activity (bidding, commenting, clicking). Every item starts with a popularity of 100. That way uninteresting items dissapear quickly and interesting ones stay on longer. So everytime a user interacts with the objects its popularity should increase (for example, everytime a get request from a unique user is made for the details of the object, its popularity value goes up by 1, every bid increases it by 10). On the opposite, everytime a minute or so passes, the popularity of all currently active items decreases. Once it hits 0, it will be "deactivated" it will still be tradable, but it will never hit the frontpage again. The problem is, how do I decrease the popularity of a queryset of all active items? I realize that everytime the user request the front page. I could just fetch all active objects, calculate the popularity within python code and sort them by hand, but that seams rather wastefull. I know I can easily set a … -
How do you clone a model and its dependencies in Django 2.2?
How do I clone a model in such a way that it includes (clones) data on FK-related models? I've looked through various related questions on Stack, and found most of them are for old/outdated versions of Django. Here's some illustrative model code (with str methods, etc omitted for brevity): class Tracking(models.Model): entry = models.CharField(blank=False, max_length=50) timestamp = models.DateTimeField(null=True, auto_now_add=True) active = models.BooleanField(default=False) class Author(models.Model): entry = models.ForeignKey(Tracking, on_delete=models.CASCADE) first_name = models.CharField(blank=False, max_length=50) last_name = models.ImageField(null=True, blank=True) class Scene(models.Model): entry = models.ForeignKey(Tracking, on_delete=models.CASCADE) location = models.CharField(blank=False, max_length=50) image = models.ImageField(null=True, blank=True) My desired result would be to clone an existing "entry" on the Tracking model, such that a new "entry" on a new row is created with its own PK, as well as cloned copies of "Author" and "Scene" data on their respective tables which also point to the new cloned "entry". Any pointers in the right direction would be helpful. I'm not finding anything in the django docs. -
'Keyerror at /' when passing user with primary key in queryset for a listview
models.py class Notes(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=100) content = models.TextField() date_added = models.DateTimeField(default=timezone.now) views.py class HomepageView(ListView): model = Notes template_name = "home.html" def get_queryset(self): # object_list = Notes.objects.filter(Q(author=self.kwargs['pk'])) return Notes.objects.filter(Q(author=self.kwargs['pk'])) It points out pk has KeyError, is there any way to get rid of it Thanks in advance...! -
SSH tunnel (via Serveo.net) not connecting to Django server
I'm using Django to host a small server (i.e. etesync), and while I'm not fully familiar with all the technical details that go into this sort of thing, I know that I run the server at 0.0.0.0:8000. I can confirm that it connects successfully when I navigate to http://localhost:8000/ and http://192.168.1.XXX:8000/ (where XXX is local device's static IP). I'm trying to set up an SSH tunnel to Serveo.net so I can access this server from outside my LAN. So, I ran: ssh -R xyz:80:localhost:8000 serveo.net in my SSH client and received the output, "Forwarding HTTP traffic from https://xyz.serveo.net." If I then navigate to http://xyz.serveo.net/, my SSH client will output, "HTTP request from [my external IP] to https://xyz.serveo.net/." However, it does not connect to my Django server. In the python terminal where I'm running my server, I do not see any new requests (whereas navigating to http://localhost:8000/ will output, "GET HTTP/1.1" for the server). Am I doing something wrong with configuring Serveo? As this is my first project involving hosting and SSH, I'm not super familiar with what the "80" in "80:localhost:8000" refers to. I've tried changing this to: ssh -R xyz:8000:localhost:8000 serveo.net but that just results in the output, "Warning: … -

Django: How to validate / Validator a "greater then" between two FormFields?
I am testing writing validator in django. So far it worked, but now i would like to write something like a "range". forms.py class AnimalForm(forms.ModelForm): weight = forms.DecimalField(validators=[validate_gtr]) class Meta: model = Animal fields = [ 'name', 'weight', 'daily_food_min', 'daily_food_max', 'species', 'farmer', ] def __init__(self, *args, **kwargs): super(AnimalForm, self).__init__(*args, **kwargs) self.fields['name'].help_text = 'Name of Animal' self.fields['weight'].help_text = 'Weight in Kg' self.fields['species'].help_text = 'choose a species' validator.py from django.core.exceptions import ValidationError from django.utils.translation import gettext_lazy as _ def validate_gtr(value): if value > 100: raise ValidationError( _('(value) Kg.

django redirect view with parameter
I was wondering if something like this is possible in Django. In my App i have the file urls.py that contains these rows: ... path('home/', views.home, name='home'), path('page/', views.page, name='page'), .... and in my view.py file i have two view like this: def home(request, value=0): print("value=", value) return render(request, 'template.html', context) def page(request): if bad: return redirect(reverse('home'), value=1) Is it possible to have the view function with a parameter (like value in this case) and then use redirection from the page view passing some value based on same condition like value=1 in this case using the format described in the urls.py? The code above always prints value=0 no matter what. The only way i can think to do this is to use global variables which i would really like to avoid.. Thank you -

How to link two variable DBs together
I am trying to think about the right way of implementing this schema. I have a piece of music with a pre-determined instrumentation. For example, Beethoven wrote a piano trio.

On a high level, I think of Performance is an "instance" of a piece of music. One would expect there to be 1 pianist, 1 violist, and 1 cellist to perform. class Performance(Event): work = models.ManyToManyField(Work_Music, verbose_name=_('work'), blank=True) players = models.ManyToManyField(Ensemble, verbose_name=_('players'), blank=True) //Ensemble is just multiple players What is the best way to parallel link the two models?

How do I translate Javascript standard error messages in Django?
I've a couple of Django projects using translations and everything works fine except Javascript error messages on forms are not translating. For example, on my Login form, if I simply press enter I will get the JS error message "Please fill in this field" in English, whether I've selected English, French, German or any other language. This is not my JS error message and if I run manage.py makemessages -d djangojs, then this message doesn't show up to translate so I don't think I need to correct through that process. Can anyone advise me how to ensure the user is getting JavaScript error messages in their language. Thanks -
Django Filtering Articles by Categories
I'm building a news web site as a part of a task I was given, homework. I have a "articles.html" template which renders all of my news articles by publish date. I added a for loop in the template to loop over the Category model and display Categories as a list.

How to Model Peer to Peer Transactions in Django?
I'm trying to figure out the correct way to model transactions between users in an ecommerce site I'm building. I want the transaction to be available to both users in a dashboard. It seems incorrect to have the transaction, and all its details, saved to both users objects. I think I need to create a separate model for transactions, with a unique id for each transaction. Then, in each user's object I could simply save that transaction id. Would I then simply give each transaction two primary keys, one for the purchaser's user.id and one for the purchasee's user.id? Is this "many to many"? Thanks for any guidance here. -
