Host a Django project on Apache2 locally
I have finished a Django project and want to deploy it over Apache2 locally over LAN. I have figured out how to connect Django with Apache2 using mod_wsgi and it worked great because I was able to use Apace2 to actually host Django on localhost. Now I want to actually make this project available to anyone on my local network. Like for instance assuming that my local IP address was 10.10.10.51 I could go to a different device connected to my local network and type in 10.10.10.51 to actually get to the Apache2 server homepage. It does that successfully. My Django project is hosted on my Apache2 localhost server at djangoproject.localhost and it works fine just on my PC. When I move on to the other PC and go to djangoproject.localhost the site is not up there. Yes they are both connected to the same LAN network. I used this tutorial to host Django on Apache2: Host Django on Apache2 with mod_wsgi -

Django GeoIP2 libmaxmind c library in a docker container
I use GeoIP2 in a dockerised Django app and am looking to improve the performance of the IP lookups. The Django documentation says: Additionally, it is recommended to install the libmaxminddb C library, so that geoip2 can leverage the C library’s faster speed. Could somebody please provide a working example of how to do this in a docker container? I am using a Django Cookiecutter template, which uses docker-compose and a python image in the Django Dockerfile: ARG PYTHON_VERSION=3.9-slim-bullseye FROM python:${PYTHON_VERSION} as python FROM python as python-build-stage ARG BUILD_ENVIRONMENT=local I'm currently using GeoIP2 like this in views.py, and it does not perform well: from django.contrib.gis.geoip2 import GeoIP2 from ipware import get_client_ip class CheckInView(View): def get(self, request, pk): if client_ip and is_routable: client_ip, is_routable = get_client_ip(request) g = GeoIP2() city_dict = g.city(checkin.ip) checkin.city = city_dict['city'] checkin.post_code = city_dict['postal_code'] checkin.region = city_dict['region'] checkin.country_code = city_dict['country_code'] checkin.country_name = city_dict['country_name'] lat_lon = g.lat_lon(client_ip) checkin.lat = lat_lon[0] checkin.lon = lat_lon[1] ... return HttpResponseRedirect(...)

Django Registration - Checks if a user already exists
The web app currently should be able to register new users. However, should a user already exists, it should redirect user to the login page with a message of "User already exists!". The Django views: def registerPage(request): form = CreateUserForm() if request.method == 'POST': form = CreateUserForm(request.POST) if form.is_valid(): email = form.cleaned_data['email'] username = form.cleaned_data['username'] if User.objects.filter(username=username).exists(): messages.info( request, 'User already exists! Try logging in.') return redirect('login') else: user = form.save(commit=False) raw_password = User.objects.make_random_password() user.set_password(raw_password) user.save() ... I filter the user by his/her username and checks if it already exists by using the exists() method. This doesn't seem to work though. Is there something I'm missing? -

Django Rest Framework Am I doing it right?
I have studied DRF myself and one question bothers me, unfortunately I have no one to ask and this question bothers me all the time. Is writing application logic in views (as in the attached code) a good approach? When sending a query to the server with the intention, for example, to accept an order, I have to update the values from models other than the order or carry out validation of statuses, change the data on their basis. In the first tutorials from which I learned, among others, JustDjango all logic is in the view. However, after writing some code and watching other tutorials, I feel that this is not the right approach. Should not save and update models be done through a serializer? If so, whether through one large serializer or several smaller serializers. class ZK_AddUpdateItemWithInstaReservation(APIView): permission_classes = (IsAuthenticated,) def post(self, request, *args, **kwargs): pzitem_id = request.data.get('pzitem_id') ordered_quantity = request.data.get('ordered_quantity') order_id = request.data.get('order_id') user_id = request.data.get('user_id') item_id = request.data.get('item_id') if ordered_quantity: if int(ordered_quantity) < 0: return Response({'error': 'Próbujesz zamówić ujemną wartość'}) try: item = Item.objects.get(id=item_id) except: return Response({'error': 'Item with given id does not exists'}) try: order = Order.objects.get(id=order_id) except: return Response({'error': 'Order with given id does not … -
Add filters to autocomplete fields in django
I have a question about autocomplete fields in django. Let's assume we have these 2 models: class Animal: name = models.CharField() is_big = models.BooleanField() class Human: pet = models.ForeignKey(Animal) And then we have the admin file which looks something like this: class HumanAdmin(admin.ModelAdmin): autocomplete_fields = ['pet'] def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == 'pet': kwargs["queryset"] = Animal.objects.filter(is_big=True) return super().formfield_for_foreignkey(db_field, request, **kwargs) class AnimalAdmin(admin.ModelAdmin): search_fields = ['name'] admin.site.register(Animal, AnimalAdmin) admin.site.register(Human, HumanAdmin) What I wanted to achieve here is to have in the animal selection dropdown only the big animals which worked, and then I decided to make that filed an autocomplete one but after making it autocomplete it seems to be ignoring my formfield_for_foreignkey filter, it is now loading all the animals. And I wanna ask how should I combine these two properly? I want an autocomplete field for animals, but I want it to consider only those who have is_big == True . My idea is that I should somehow capture what is entered on the autocomplete textfield and add that to my filtering but I'm not sure how to do that. -
How do I livestream the video I have captured using OpenCV on my webpage which is made using Django while also keeping the face recognition function
I am a new developer working at an interI am developing a web application which takes your attendance using face recognition and puts the entry in the database using django, python, open-cv and the face_recognition library of python. The Login page looks like this: Login Page. When I click the login button, my views program directs to an external python function which opens a separate camera window which does the face recognition. The Camera Window. What I want to do is display the camera directly in the browser window rather than as a separate window. I found some tutorials and also tried to implement them but using them I can only display the frames in the browser window while the functionality of face recognition is lost. The Views Code (views.py): def camera_on(request): out = Popen('E:/Study/Internship/Capstone/Project/Web App/web_app/Basic.py', shell=True, stdout=PIPE) op = out.stdout.read().decode("utf-8") new_str = '' for i in range(len(op)-2): new_str += op[i] request.session['name'] = new_str return render(request, 'open_camera.html', {'data': new_str}) This code accesses the Basics.py file which opens the camera window, does the face recognition and gives the entry in the database. The Basics.py code: from datetime import datetime, date import os import django os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'web_app.settings') django.setup() import cv2 import face_recognition … -
How to display choices in a django form based on a database
I am writing a django application that helps create a shopping list based on the store stock. The store stock will be stored as a database that looks like this (please ignore spelling errors!): Type Name Colour Fruit Apple Pink Fruit Apple Green Fruit Banana Yellow Fruit Banana Green Fruit Clementine Orange Fruit Blueberry Blue Veg Tomato Red Veg Spinach Dark green Veg Kale Dark green Veg Dwarf beans Light green From this store stock, a user can create a shopping list by choosing the above three fields using a form. The user will first choose the type - which should be displayed as a choice between "Fruit" or "Veg". Then when they choose "Fruit" for example, only the fruits should be provided as choices in "Name". Finally, for them to choose colour, only the corresponding colour of the chosen fruit should be displayed as the options in the form. To create the store stock database, the form I created is as follows: Class Stock(models.Model): Type_choices = models.TextChoices('Fruit','Veg') stock_type = models.CharField(choices=Type_choices.choices) name = models.CharField(max_length=264, unique=False) colour = models.CharField(max_length=264, unique=False) I then populated it to look like the above table. To store the shopping list, I created a model: Class ShoppingList(models.Model): … -

How to add extra key in created object in Django Rest Framework?
I'm new to Django Currently I'm trying to add a simple extra key on my returned json in the serializer. Here's the create() override of my serializer: def create(self, validated_data): available_dates = validated_data.pop("available_dates") # Default expiry time is 3 days expiry = datetime.datetime.now() + datetime.timedelta(days=3) event = Events.objects.create(**validated_data, expiry=expiry) for selectedTime in available_dates: AvailableDates.objects.create( event=event, **selectedTime, ) signer = Signer() signedObject = signer.sign_object( {"expiry": expiry.isoformat(), "id": event.id} ) return {**event, "signed_url": signedObject} As you can see, I don't want to only return event, but I want to add a signed url. This gave me an error: 'Events' object is not a mapping So then how do I add extra key? What do I return in the create function? Can I create Response() as the return of create function in DRF? -

Django models with mutually exclusive references
I think I have this completely muddled in my head and would like some help please. I am new to this, so be gentle. I have a model of a transformer core: class Core(models.Model): name = models.CharField(max_length=100, default="") laminations = models.ForeignKey(Lamination, on_delete=models.CASCADE) ccore= models.ForeignKey(Ccore, on_delete=models.CASCADE) stack = models.FloatField() stack_factor = models.FloatField(default=0.92) def __str__(self): return self.name I don't think I am doing this correctly. A Core can have either a lamination OR a ccore but not both. How do I set up the relationship between Core and lamination and ccore so that I can select which one (maybe late on a different type as well) is valid? I thought of having a selection called core_type, that the front end would then be able to change, and depending on this selection one of these ForeignKeys is set to NULL. But that feels wrong to me. -
