how can I use 2 database models in Django programming?
in my models.py , I have 2 database named 'DB' and 'Rent'. what I want to do in my html page is to subtract rented number ( which is in Rent database ) from total number ( which is in DB databases ). I wonder if there is possible way to use for loop which first loop uses DB databases and second loop uses Rent databases. point is that I have to lookup both databases every loop. {% for p in DB %} <tr> <td>{{ p.product_name }}</td> <td>{{ r.rented_num }}</td> <!-- how can I do this??? --> <td>{{ p.total_num }}</td> </tr> {% endfor %} -
How to add object to ManyToMany field in django?
I have several models/table classes: class User(AbstractUser): pass class Listing(models.Model): title = models.CharField(max_length=65, null=False) description = models.TextField() starting_bid = models.PositiveIntegerField(null=False) image = models.URLField(null=True, blank=True) category = models.ForeignKey(Category, on_delete=models.CASCADE) user = models.ForeignKey(User, on_delete=models.CASCADE) date = models.DateField(auto_now_add=True) def __str__(self): return self.title class Watchlist(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) listing = models.ManyToManyField(Listing) def __str__(self): return f"Watchlist item of {self.user} user. Product: {self.listing}" I've registered these models in admin.py file: from django.contrib import admin from .models import Category, Listing, Bid, Comment, Watchlist, User # Register your models here. admin.site.register(Category) admin.site.register(Listing) admin.site.register(Bid) admin.site.register(Comment) admin.site.register(Watchlist) admin.site.register(User) When I go to the admin interface and trying to add item to the watchlist table I see the next form where I cat pick User to which will be belong that new watchlist object and also I can pick one or more Listing items: But when I hit save it saves Watchlist object with filled User field, and listing field stays empty. My question is how to add record to ManyToMany field in general and how could be added more than one item to the row with only two columns (admin and listing). Django Admin specifies literally that: "Hold down “Control”, or “Command” on a Mac, to select more … -
correct use of class method in django
I had studied class methods in python but never really understood its application in Djnago. My coding life was going well without the use of it. But I came across a situation where class method will be useful. My model: class Example(models.Model): post_count = models.IntegerField(default=0) @classmethod def total_counts(cls): return cls.objects.values('post_views').annotate(sum logic) In the above function, if I had used property decorator, i can only get a single object post_count because the object self is used. But if I use classmethod then I can count the post views of all the objects. So my thought is that whenever we have to deal with all the objects instead of a self object we need class method. Is this correct? Also, can we use this class method directly into our model serializer field just like we use property to serializer?? -
Django - Changed url to re_path, now getting 404 error
I've changed my url to re_path and am now getting 404, not found error. Any ideas?

HTML form sending duplicate files to the django server

Django - creating a model with circular relationship - from instance to another instance?
I am currently working on a small project. Two models are of interest: -Warehouse -BetweenWarehouseTransfers Note: each warehouse has multiple items in a different model (which are the products); Question: I want to be able to transfer the items from one warehouse to another. To this end in BetweenWarehouseTransfers I would like to have one field specifying the warehouse to which I am transferring speak item (to_warehouse) and one field specifying from which warehouse this item is coming (from_warehouse). Later on I would like to add autocomplete_fields to these two fields which only accept existing warehouses as inputs. Does anyone have an idea on how to create this circular relationship. I have posted a couple of solutions which I envisioned but each time there is a circular relationship problem: #0.

How to use same ListView class for different model?
There are 3 models (companies, divisions and staffgroups) to display as list. I am trying to create a class base view extended from ListView to list various models through passing the model name in the URLpatterns.

Access GCP VM via HTTPS
Hi everyone I have a GCP VM (Debian 10 image) running a Django REST API via Nginx and Gunicorn. Since I need to call the API via HTTPS I created a load-balancer with HTTPS frontend and HTTP connection to the VM on the backend. When I call the load balancer domain it connects via HTTPS to the VM. However, instead of the Django REST API, the standard NGINX message is displayed. If I call the IP of the VM directly, without the load balancer, it still displays the Django REST API. How can I access the Django REST API via the load balancer through HTTPS? Also if there are other easy-to-implement ways of accessing the VM via HTTPS without the load balancer I d be interested. Cheers -
django reference to an entire table, not to a specific entry
I'm currently working on a setting system. here i create settings for the display of different models. I'm just missing an efficient reference to the model/table. With the foregnkey you can set a reference to a specific instance, but I'm looking for a reference to an entire table. I'm currently doing it via a charfield, but find it inefficient. is there some kind of modelField? class A(models.Model): pass class B(models.Model): pass class C(models.Model): pass Classes A, B and C are any datastores for which I want to store settings. class foo(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) classname = models.CharField(max_length=64) parameters of settings foo is the class in which I want to store the settings for the other classes settingsA = foo.objects.filter(user=user, classname = A.__name__) settingsB = foo.objects.filter(user=user, classname = B.__name__) settingsC = foo.objects.filter(user=user, classname = C.__name__) -
Update profile avatar DRF and Vue.js
I am not fully understanding why I can not update an image url in my DRF api. I am using djoser for the api endpoints and activation, django rest framework and vue.js for the frontend with axios making the API requests.

Django VSCode debug raising exception for code that actually works
I have looked into similar questions, but found none exactly similar to the issue I'm facing. I am not using a virtual environment. I wanted to test debugging django project/app files in VSCode but I'm stuck with 'fake' import exceptions. Everything seems to be working as expected, but for some reason VSCode's debugger can't find my files. Here's the code snippet: from django.contrib import admin from .models import Paciente The first line doesn't raise any exceptions. The second one, though, raises this: Exception has occurred: ImportError attempted relative import with no known parent package So I put the parent folder in the path, like: from app.models import Paciente but then I get another exception: Exception has occurred: ModuleNotFoundError No module named 'app' So then, I tried removing the python path syntax, leaving just "models", as in: from models import Paciente I then get another exception, this time not in the admin file (the one I was trying to debug), but in the models file, complaining that: Exception has occurred: ImproperlyConfigured Requested setting USE_TZ, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. Except it is configured in settings.py. It's there(always … -

Forigen Key not displaying in rendered model form
I am looking for guidance on where I am going wrong. My model form is rendering correctly however the author has no option to select or input.

In DJANGO, how do I query for records that do not exist after a certain date?
Assume I have a model as such: class Invoices(models.Model): customer = models.ForeignKey(Customer, ...) date = models.DateField() amount = models.FloatField() I want to know all customers that have not purchased for the last 30 days. Basically the inverse of this query: no_sales = Invoices.objects.filter( date__gte=certain_date_30_days_ago ).values( 'customer__code' ) using .exclude() just excludes the customers who have purchased in the last 30 days but not include the people who have not purchased in the last 30 days. Any thoughts? :) Thanks! -
