Generic Django template to display multiple tables
Is there a way to create a generic html table in Django. I want to reuse the same form.html to display entities with different columns. For example in the below code a pass a list of headers, and dynamically create the thead,but I need for each row in the body to get every value. So I need to iterate. Or is there any other approach to reuse templates in a mo generic way instead of build N templates for each table yuo need to display <table class="table table-bordered" id="vendor_table" style="text-align: center;"> <thead class="tables-success"> <tr> {% for header in list_headers %} <th>{{ header }}</th> {% endfor %} </tr> </thead> {% for row in list_values %} <tr> {% for header_name in list_headers %} <th> {{ row.{{ header_name }} }} </th> <--------- {% endfor %} </tr> {% endfor %} </table> -

Dear masters! Please help me with this question. models.py class New_tables(models.Model): TYPEBET_CHOICES = ( ('1','up'), ('0', 'down'), ) type_bet = models.IntegerField(choices=TYPEBET_CHOICES) form.py type_bet = forms.TypedChoiceField(choices=New_tables.TYPEBET_CHOICES) how to make sure that when you select from the list, there are not “up” and “down”, but that instead of them a picture is displayed, preloaded in /media/ ?

Can Django ORM calculate market share of specific brands over multiple time periods in a single query?
I have the following Django model: class MarketData(models.Model): category = models.CharField(max_length=64, null=True) brand = models.CharField(max_length=128, null=True) time_period = models.DateField() sales = models.IntegerField(default=0, null=True) I am trying to use Django's ORM to calculate the market share of each brand within each time period of my dataset to output to a line chart. The market share calculation itself is simple: the sales of each brand within the time period divided by the total sales in each time period. I can use Django's ORM to generate a queryset of brands and sales by time period, but I'm struggling to annotate the additional metric of sales for all brands. My current query: sales = MarketData.objects.filter(brand__in=['Brand 1', 'Brand 2']) \ .values('time_period', 'brand') \ .annotate(sales=Sum('sales')) \ .order_by('period', '-sales') My current queryset output: <QuerySet [{'time_period': datetime.date(2020, 6, 30), 'brand': "Brand 1", 'sales': 21734}, {'time_period': datetime.date(2020, 6, 30), 'brand': 'Brand 2', 'sales': 93622}]> How can I add another annotation that includes the sales of ALL brands for that time period, not just the brands specified in the filter, and not just the current brand? I have tried to use a Subquery to get the total market sales by period, but I end up with an aggregate across all … -
Django.auth.authenticate not authenticating user
I am creating an app, and I am trying to manually create the login page so I can add some things that I can't add using the default Django authentication pages. This is what my view looks like: def logIn(request): formClass = LogInForm template = "login.html" if request.method == "POST": auth.authenticate(username=request.POST["username"], password=request.POST["password"]) return redirect("/") return render(request, template, { "form" : formClass }) But, when I print out the user's id after logging in, it returns none. Does somebody know what is going on? -
Why isn't session value persisting with Django Rest Framework (DRF)?
thank you for your time and attention to this query. I am trying to set (key, value) into the request session from one drf function and accessing that (key, value) via the request session in another drf function. Please see the code below for the current implmentation: class FunctionOne(GenericAPIView): permission_classes = (permissions.AllowAny,) authentication_classes = [] def get(self, request, *args, **kwargs): request.session["kcc"] = request.GET.get("code") request.session.modified = True print("kcc", request.session.get("kcc", None)) return redirect("http://localhost:3000/checkout") class FunctionTwo(GenericAPIView): permission_classes = (permissions.AllowAny,) authentication_classes = [] def get(self, request, *args, **kwargs): print(dir(request.session)) code = request.session.get("kcc") if code: return Response(status=status.HTTP_200_OK) else: return Response(status=status.HTTP_404_NOT_FOUND) It is successfully setting the (key, value) into the session in function one and can be seen via the print statement. However when accessing the function two view the (key, value) saved in the session can't be found. I've checked the settings.py "django.contrib.sessions.middleware.SessionMiddleware" is included in the middleware and also these are the current rest_framework settings: REST_FRAMEWORK = { "DEFAULT_AUTHENTICATION_CLASSES": [ "backend.authentication.FirebaseAuthentication", ], "DEFAULT_RENDERER_CLASSES": [ "rest_framework.renderers.JSONRenderer", ], "DEFAULT_PERMISSION_CLASSES": [ "rest_framework.permissions.IsAuthenticated", ], } Additionally, I am not using the default Sqlite database that is shipped with Django, I have a postgresql database hooked up to the project instead. I would greatly appreciate if pointed in the … -
how to use ckeditor for two fields in django crispy form?

Least painful way of not using int4 as primary key in Django user models?
I'm new to Django, and upon running the first migration, it seems the primary key ID of the auth_users table is an int4. Looking through the docs, it seems if I use any kind of custom User model, for example to bigint or uuid, I am opening a can of worms and losing Django Admin functionality and possibly all sorts of auth scaffolding functionality? Is there a standard way of not using int4 that I'm failing to see, let's say using UUID, short of going full custom on the auth backend? Tried custom model extending django.contrib.auth.models.AbstractUser. Django Admin stops working, which seems expected according to documentation. However, auth scaffolding, such as python manage.py createsuperuser also starts throwing errors, such as django.db.utils.IntegrityError: null value in column "id" of relation "users_user" violates not-null constraint. This is when id is a Postgres UUID. Here's the User model: class User(AbstractUser): id = models.UUIDField(primary_key=True) -
How do I use a statically hosted design template in a Django Project
I need to use elements from a statically hosted design template in a django site. When I try using resources from the statically hosted site hosted on github pages the content is available, however when I hosted the static host on an ec2 instance (using http with Apache) the content from the design template is not available. Any thoughts on what the issue might be? Possibly using http vs https? Ideally I would like the static content to be hosted in AWS in order to control access to it and do not want to use django's local features for rendering static content. I tried using a statically hosted design template hosted over github pages and an ec2 instance, it works on the github pages but not the ec2 host. I tried changing the aws security groups on the ec2 instance -

Django new entry fetching previous entry in Postgres and not creating a new one
This is my first time here, and I'm trying to develop an app for a personal project (journal app) using Django and Postgres. When I use the Shell method, I am able to create a new entry into a table defined in my Postgres DB. However, when using the browser method, it keeps retrieving the last entry in the DB instead of creating a new one. I tried calling the entry_id in my views.py file and made sure to call the save() method to save a new entry. But instead, it keeps fetching the latest entry from the DB. Any help and/or direction is highly appreciated by someone who's just learning. Misael VIEWS.PY from django.shortcuts import render, redirect from .models import Entry from .forms import EntryForm from django.urls import reverse def entry_form(request): latest_entry = Entry.objects.latest('id') latest_entry_id = latest_entry.id if latest_entry else None if request.method == 'POST': form = EntryForm(request.POST) if form.is_valid(): entry = form.save() # Save the form data to the database return redirect(reverse('journal:entry_success', kwargs={'latest_entry_id': entry.id})) # Pass the latest_entry_id as a parameter else: print('Form errors:', form.errors) else: form = EntryForm() return render(request, 'journal/entry_form.html', {'form': form, 'latest_entry_id': latest_entry_id}) def entry_list(request): entries = Entry.objects.all() return render(request, 'journal/entry_list.html', {'entries': entries}) def entry_success(request, … -
Display the value of current foreignkey in update form when limiting queryset choice
I have a model named TimeTable (as shown below). In my update form I want to display the current value of the foreignkey field (say 'mon_1').

Django test multiple databases managed and unmanaged
My setup: one managed database for "django-stuff" (auth, admin, contenttypes, sessions) one unmanaged database for the company_db I am trying to create a test databases for both. Django only sets up the test database for the company_db and adds the tables from django-stuff to that db. It does not add the company_db tables to the django_test_company_db.

How to retrieve the first object for each set of values in a django filter operation?
I'm running a django 1.29 app on a postgresql database. I have a model similar to this: class DataFile(models.Model): user = models.ForeignKey('data.User', verbose_name='Data View') period = models.ForeignKey('data.Period', verbose_name='Period') category = models.ForeignKey('data.Period', verbose_name='Period') created = models.DateTimeField(auto_now_add=True,null=True) My code is currently retrieving objects that the program needs as this: pending_ids = pending_files.values_list("id", flat=True).distinct() my_data = pending_files.values_list("user_id","category_id","period_id") import_files_pending=[] for u, c, p in pending_bu_way_period: last_file_bpw = DataFile.objects.filter(user_id=u, period_id=p,category_id=c).order_by('-created').first() if last_file_bpw and last_file_bpw.id in pending_ids: import_files_pending.append(last_file_bpw) But is very inefficent, so I tried refractoring and came up with this: import_files_pending2 = DataFile.objects.filter(id__in=pending_ids,user_id=my_data.values_list("user_id", flat=True), category_id__in=my_data.values_list("category_id", flat=True), period_id__in=my_data.values_list("period_id", flat=True)).order_by('user_id', 'period_id', '-created').distinct("from_who_id", 'period_id') But it appears to retrieve much more objects other than the ones I need. What am I doing wrong? Why is my refractoring giving different results? For what I understand, my query is not retrieving only the first instance for the other values' combination, but any of them. -

How to resolve an InconsistentMigrationHistory in Django?
In our django project we had over 900 migrations and they were slowing down our tests. Due to complex interdependencies between apps, we decided that squashing wasn't a real option, so we wanted to reset them. However we have a couple of 3rd party apps as well (celery etc.) with their own migrations. After running python manage.py shell -c "from django.db import connection; cursor = connection.cursor(); cursor.execute(\"DELETE FROM django_migrations WHERE app IN ('api', 'user');\")" and makemigrations we are now trying to apply the migrations with --fake-initial. We are now getting the error django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency user.0001_initial on database 'default'. which makes sense as the database currently "thinks" that it has celery, admin etc. installed, but not user (even though it has). How could we work around this issue? Also we can't loose any data, otherwise I would just delete the migrations for this as well or reset the entire database. -

Django model with properties that come from an external API
I want to have properties on a model that come from an external API. I also want to leave those properties blank when the ORM loads an instance of the model so that queries within the ORM aren't making API requests unless explicitly asked. It'd be nice if I could call a function on the model to retrieve those external properties, maybe something like .with_external(). How could I achieve this?

Dockerfile for Nginx is the official image from Docker Hub v 1.25.1. There's no docker-compose/podman-compose available on the server. I'm starting the build by creating a dedicated network: podman network create testapp-net The next component is Django application: podman build -t testapp-django -f src/testapp-django/compose/django/Dockerfile . Dockerfile for the app is based on Ubuntu base image and I'm exposing port 8000: FROM ubuntu:22.04 ... RUN addgroup --system django \ && adduser --system --ingroup django django ... WORKDIR /app ... RUN chmod +x /app ... EXPOSE 8000 ...

Which frame work to use to build a web app [closed]
I have a desktop application that used to work with the tkinter package. But I need to turn it into a web application, so I have to rewrite it. I don't know which framework to choose between Django, Turbogears, Web2py and Cubicweb, as I'm not familiar with any of them. My application has 4 pages, the home page and 3 other pages accessible via buttons on the home page. These tabs contain large graphs in the form of a network and a map with numerous filters, everthing is built using data loaded when the application is launched (the data are loaded using an url link). The application also features images, help buttons that open a help pdf, and buttons to return to the home page. I have no idea which framework would be best suited to my problem and at the same time the easiest to use. From what I've read, I'd go for Django, even if it's a bit complex, especially as there are lots of tutorials on youtube. Thanks !
