View function that handles only POST requests to check database
My friends and I are writing a game that uses a website for registration/login. When a player logs into the game, it'll check the Django website's SQLite database using a POST cURL request or an equal to see if the player is valid. What should I sent in my request and how should I write my function that handles this? http://127.0.0.1:8000/login/ Login includes Username Password import requests url = 'http://localhost:8000' data = { "username": "password" } x = requests.post(url, data=data) print(x.status_code) Currently, this is all I have. It tells me I have to add the CSRF token. But would just doing this and adding the csrf token work? -

Access One to One Field property in DRF Serializer
I am having trouble with setting the password as a write_only property in my Serializer. This is what I currently have, and I want to hide the password. { "nit": "54545445", "direccion": "ciudad", "telefono": "54545454", "usuario": { "id": 12, "password": "asdf12321", "last_login": null, "is_superuser": false, "username": "admin3", "first_name": "admin3", "last_name": "admin3", "email": "admin3@gmail.com", "is_staff": false, "is_active": true, "date_joined": "2021-06-24T20:47:56.286694Z", "groups": [], "user_permissions": [] } } There should be a way of getting that value in my serializer to set the write_only=True property. class UserExtraSerializer(serializers.ModelSerializer): class Meta: model = UserExtra fields = ['nit', 'direccion', 'telefono', 'usuario'] depth = 1 extra_kwargs = {''''access usuario['password'] here''': {'write_only': True, 'required': True}} -

FloatField vs DecimalField in Django and JS/React
I have a Django app as the backend a React app as the frontend. Most of my Django fields related to prices/monetary values were FloatField. It worked with the frontend: when receiving objects from the backend I could see that those fields were numbers and I could make calculations with them. But I've recently changed from FloatField to DecimalField, and now on the frontend the prices are assumed as string. Why is that happening and what is the best approach to deal with this? Has anyone experienced something similar? -
Avoiding duplicate row entry inside django model
I have a CarRent model that is a ForeignKey to the Car model. On the Car detailView page i have a button for drivers to place a Rent which will result in adding a row to the CarRent Table. The rent isn’t active yet until the Car owner approves the rent request. The problem now is that a driver could click the rent button multiple times thereby resulting in many duplicate rows in the CarRent model and also multiple redundant car rent request to the car owner. I am looking for a way to hide the “Place A Rent” form if the current user (driver) has already requested for a particular car and rent_approval is not True. Thanks. Any help will be greatly appreciated. models.py class Car(models.Model): car_owner = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='car_owner', on_delete=models.CASCADE) car_model = models.CharField(max_length=20, blank=True, null=True) rented = models.BooleanField(default=False) class CarRent(models.Model): car = models.ForeignKey(Car, related_name='rented_car', on_delete=models.CASCADE) driver = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='driver_renting', on_delete=models.CASCADE) rent_approval = models.BooleanField(null=True) active_rent = models.BooleanField(default=False, null=True) views.py class CarView(LoginRequiredMixin, UserPassesTestMixin, FormMixin, DetailView): model = Car form_class = RentForm def get_success_url(self): return reverse('app:car-detail', kwargs={'pk': self.object.pk}) def post(self, request, *args, **kwargs): form = self.get_form() self.object = self.get_object() if form.is_valid(): return self.form_valid(form) else: return self.form_invalid(form) def form_valid(self, form, *args, **kwargs): … -
Loading of Django test fixtures into database
I'm trying to do some test-driven development and would find it useful to look inside the database to see what's being done using database tools in PyCharm. I load up the test fixture here: case6_fixtures = ['test_case6.json'] try: call_command('loaddata', *case6_fixtures, verbosity=9) except Exception as ex: print(str(ex)) And it seems to be loading. Loading 'test_case6' fixtures... Checking '/Users/user/Workspace/application/application/fixtures' for fixtures... Checking '/Users/user/Workspace/project' for fixtures... No fixture 'test_case6' in '/Users/am034402/Workspace/project'. Installing json fixture 'test_case6' from '/Users/user/Workspace/application/application/fixtures'. Processed 2 object(s). Installed 2 object(s) from 1 fixture(s) If I try to query it with the Django ORM, I get a record back, and it matches what is in the fixtures file. However, if I query the sqlite3 db file that is supposed to have something in it (testing.db): DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), 'TEST': { 'NAME': 'testing.db' } } } nothing's there. The same can be said for db.sqlite3. Yes, the tables are there, but they're empty. I'm thoroughly confused. Does Django's test runner load these fixtures into memory or something? Shouldn't there be data in those database tables in testing.db? -
Is shifting an existing Django project to FastAPI a good idea?
I am working on a Django project currently and recently I came across FasAPI. After seeing all the advantages of FastAPI, I am really tempted to shift my project to it. The current project is pretty huge and it's gonna take a while to switch. Is it worth switching to FastAPI spending such a huge effort in the long run? -

Django / Model Forms
Completely new to all computer programming and trying to build an app that tracks my smoking habits. The first step was creating a Django model called packs: class packs (models.Model): timestamp = models.DateTimeField(auto_now_add=True, auto_now=False, blank=False) num_packs = models.SmallIntegerField(max_length=10) cost_packs = models.DecimalField(max_digits=6, decimal_places=2) Next I created a forms.py page and this is where I started getting lost: from django.forms import ModelForm from .models import packs class packsForm(ModelForm): class Meta: model = packs fields = ['num_packs', 'cost_packs'] Of course that led to my failure in HTML trying to render a page that has all the form data: {%block content%} <div class = "form_pack"> <h3>FORM PACK</h3> <p> <form method="POST" action="."> {% csrf_token %} <input text="cost_pack" name=cost_pack> {{ form }} <input type="submit" value="save"/> </form> </p> </div> {% endblock %} To help my view.py looks like this: def packs_create(request): form=packsForm(request.POST or None) if form.is_valid(): return render(request, 'pack/index.htmnl', {'form': form}) Now when I refresh the page I don't get the form. Just the one input i put in. Can someone help me sort out which path I got lost in and where I need to connect the dots? I believe my forms.py is not complete, but not sure where to progress... Thanks, DrKornballer -
Optimizing for loop inside for loop django
I have a function which checks for a profile name and determines if it is in a tagged profile name. def check_profiles(request): try: # get all individual profiles profiles = Profile.objects.all() # get all individual tagged profiles tagged_profiles = TaggedProfiles.objects.all() # ids to exclude in adding dates exclude_profiles = [] # for profile in profiles for profile in profiles: # for tagged in sdn list for tagged_profile in tagged_profiles: # if contains 1 if any(name in tagged_profile.name_breakdown() for name in profile.name_breakdown()): # put in exclude exclude_profiles.append(profile.pk) profile.status = 'FOR REVIEW' profile.save() break for profile in Profile.objects.all().exclude(pk__in = exclude_profiles): cleared_dates = profile.cleared_dates cleared_dates.append( { 'date': datetime.now().strftime('%Y-%m-%d'), 'time': datetime.now().strftime('%I:%M %p') }) logger.debug(cleared_dates) profile.cleared_dates = cleared_dates profile.save() except Exception as e: logger.error(e) Basically, if a profile's name is 'firstname lastname', it's breakdown is ['firstname', 'lastname']. And if tagged_profiles include either a 'firstname' or a 'lastname' in any of it's breakdowns, it's a hit. But I'm doing it very inefficiently. How may I optimize it with any of django's built in functions? -

Django filter on combination using F
I wrote the following query using the Django ORM: fixtures = Fixture.objects.filter(league=league).filter((Q(predictions__value__gt=0.0) & Q(predictions__team=F("home"))) & (Q(predictions__value__gt=0.0) & Q(predictions__team=F("away")))) With this I'm trying to filter out each fixture where the prediction__value for the home is greater than 0.0 and the prediction__value of the away is greater than 0.0. Sadly my query is returning 0 records upon using .count() whereas it should return almost every record. When I only use one part of the query; so either the home or the away part the query does return a certain amount of records. The value of league is irrelevant here. -

I suppose that I have to override the save method too, but I don't know how. Thanks in advance -
