Is the sqlite database (the default django database) good enough?
I am building this ecommerce app with django, and I was thinking if the default database (sqlite) was fine enough? My django app is going to have around 200 different products, and for payments I will use stripe API. I do not expect too much traffic when the app is up, since it's a website only for the country I live in with 6 million inhabitants. So can I settle with the sqlite database? -

Print users' data inside a template in Django
I'm new to Django and I'm trying to print users' information such as email, first name, username in a template that should work as "My Profile Page".

DRF - enable single object lookup without filter
Using default DRF Viewsets with the following models and model serializers: class Company(Model): active = BooleanField() class Person(Model): company = ForeignKeyField(to=Company) My filter for Companies: class CompanyFilter(filters.FilterSet): ... @property def qs(self): parent = super().qs if 'active' not in self.data: return parent.filter(active=True) return parent I would like to: hide inactive companies by default have a proper navigation from all persons, even to companies that are deactivated According to DRF docs: Note that if a filter backend is configured for a view, then as well as being used to filter list views, it will also be used to filter the querysets used for returning a single object. If I introduce the filter mentioned, a user navigating from person to his company will get a 404 if this company is inactive. He would need to set a GET parameter on a single object lookup which is impossible to know. -

EditUserForm() create a new user insted of editing the correct one in Django
I'm new to Django and I'm building my first website. I'm now in the phase of creating the register/edit profile pages. I have correctly created my register page but I'm having a hard time creating the edit profile page. My profile has the classic fields username, first name, last name, email, password. On my edit page, I would like to be able to modify only the email field. For some reason, instead of editing the current user, my edit profile page creates a new user with every field blank except for the one I've edited.

After input some required information, if the user click the button "Get Pice", the price will be shown in the botton page (here I am using htmx to partially refresh the home page). if the user click the button "Order Now", it will need to redirect to the new page called CreateOrder.html at path: "homepage/order/", where the price will be shown in this new page. below is the full codes.

Django channels served with gunicorn with --preload can't connect to unix socket
I'm working on a web app that uses django channels for websocket communication. On production im using gunicorn with uvicorn workers, behind Nginx, proxying via unix socket. My objective is to have code executed only once (to log configuration and schedule jobs with APScheduler), when the app starts. Considering this asgi.py file: import os from django.core.asgi import get_asgi_application from .startup import run_at_startup os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tcpy.settings') django_asgi_app = get_asgi_application() from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter, URLRouter import tcpy.routing application = ProtocolTypeRouter({ "http": django_asgi_app, "websocket": AuthMiddlewareStack( URLRouter( tcpy.routing.websocket_urlpatterns ) ), }) run_at_startup() I found that using --preload argument in gunicorn, makes the run_at_startup function run only once per boot. The problem is that gunicorn cannot connect to the unix socket. If i take the --preload, everything works fine but run_at_startup will run once per worker process (i dont want that). This is my systemd configuration file to create the socket ( /etc/systemd/system/tr_gunicorn.socket ): [Unit] Description=Testrune unix-socket for http communications (nginx<>gunicorn) [Socket] ListenStream=/run/tr_gunicorn.socket SocketUser=testrune SocketGroup=www-data [Install] WantedBy=sockets.target And this is the file that launches gunicorn ( /etc/systemd/system/tr_gunicorn.service ): [Unit] Description=Testrune Webserver Requires=tr_gunicorn.socket After=network.target [Service] EnvironmentFile=/etc/testrune/environment.env User=testrune Group=www-data WorkingDirectory=/home/testrune/tcpy_srv/testrune/tcpydev/tcpy/ ExecStart=/home/testrune/tcpyenv/bin/gunicorn tcpy.asgi:application -w 2 -k uvicorn.workers.UvicornWorker --bind unix:/run/tr_gunicorn.socket --forwarded-allow-ips='*' --preload Restart=on-failure [Install] WantedBy=multi-user.target These … -

Why can't I use SoftDeletableModel and TimeFramedModel together in Django model?
I need a model that should be soft deletable (not actually deleting from DB) and should have start and end timestamps. I've used SoftDeletableModel and TimeFramedModel from django-model-utils library for this purpose. This is my models.py from model_utils.models import TimeFramedModel, SoftDeletableModel class Quiz(SoftDeletableModel, TimeFramedModel): """ Model for quiz """ total_questions = models.PositiveSmallIntegerField(_("Total no of questions")) duration = models.PositiveSmallIntegerField(_("Duration (in mins)")) This works fine in shell as well as in the APIs. But I'm not able to see any data in Django admin. I tried using one of them at a time, and it works fine. I checked the data using shell as below: >>> from apps.quiz.models import Quiz >>> Quiz.objects.all() <SoftDeletableQuerySet [<Quiz: Mathematics Quiz>, <Quiz: Mathematics Weekly Quiz>, <Quiz: Monday GK Quiz>]> And this is what I see in Django admin: Now I've two questions here: What is the reason I get no data in admin panel when using both together? How can solve this issue while using these prebuilt model classes only? (If its possible) Any help is really appreciated. Thank You !! -
Is it possible to pass a value from HTML page to Django view using GET method?
I have a base sidebar that contains two items page1 and page2. When the user clicks on an item, it will render the corresponding page. I also have a filter in the sidebar that allows the user to filter the results on the page by type. I am able to see to appropriate results on the page when I choose a filter, but my aim is to make the system remember the last filter selection so when the user chooses a new page, it will automatically show the results by the last selected filter. can this be done by sending the variable 'type' through the GET method? or any other solution would be appreciated. in base.html, Rendering a New Page via Get method <div id="page" class="collapse" aria-labelledby="headingUtilities" data-parent="#accordionSidebar"> <div class="bg-white py-2 collapse-inner rounded"> <a class="collapse-item" href="page1">Page1</a> <a class="collapse-item" href="page2">Page2</a> </div> </div> in base.html, Filtering the current page via POST method <div id="collapseTwo" class="collapse" aria-labelledby="headingTwo" data-parent="#accordionSidebar"> <div class="bg-white py-2 collapse-inner rounded"> <h6 class="collapse-header">Filter By Type:</h6> <form name="modality" action="" id='type' method="post" enctype="multipart/form-data"> {% csrf_token %} <input class="collapse-item" name ='type' type="submit" value="type1" onclick="this.form.submit()"> <input class="collapse-item" name ='type' type="submit" value="type2" onclick="this.form.submit()"> <input class="collapse-item" name ='type' type="submit" value="type3" onclick="this.form.submit()"> </form> </div> </div> django view: @login_required(login_url='login') … -

filter a request in django serializer with the current logged-in user
Help please, So, I am making a request with a serializer and what I need is to filter the response by current logged-in user. I was thinking about doing the request using serializerMethodField but it's a read-only type so I could not do anything with it after. Specially this code line which is necessary for my form, because it will retrieve all wallet linked to the current user into a select field, won't work : to = serializers.PrimaryKeyRelatedField(queryset=serializers.SerializerMethodField('get_user_wallets')) I thought also about the way of castrate the return type that I will get from get_user_wallets method into something that I can use as a queryset. But it seems not easy to do it. Maybe someone has a better approach of doing what I want. Bellow is the code : class TransactionSerializer(serializers.HyperlinkedModelSerializer): to = serializers.PrimaryKeyRelatedField(queryset=serializers.SerializerMethodField('get_user_wallets')) class Meta: model = Transaction fields = ['amount', 'to'] def get_user_wallets(self, obj): request = self.context.get('request', None) if request: wallet = Wallet.objects.filter(user_id=request.user.pk) return wallet Thank you for your answers and suggestions. -

Djano email with ics file doesn't adding event in google calendar
I am developing a web application. In there I am creating a zoom meet and send it with email. So i created ics file using django ics this package. The email is getting successfully. And there is an ics file as attachment. But it does not make an event in my google calender. My code is # Creating ICS file for calender invite calendar = Calendar() event = Event() event.name = meet.title event.begin = meet.meet_start_date_time event.end = meet.meet_end_date_time event.organizer = partner_user.email event.uid = meet.zoom_uuid event.url = meet.join_url calendar.events.add(event) filename_event = 'invite-%d.ics' % meet.id with open(filename_event, 'w') as ics_file: ics_file.writelines(calendar) email = EmailMultiAlternatives(subject, plain_message, from_email, [to]) email.attach_alternative(html_message, 'text/html') email.attach_file(filename_event, 'text/calendar') email.send(fail_silently=True) os.remove(filename_event) I am using a stack overflow answer answer as a reference. Can anyone help me to solve this. Thanks in advance.
