Run python script with multiple users accessing Django server
I have built a python script to run some process in downloading files and serve to users, I also built a website and added it to the Django framework, Now it is working properly for a single users (tested in the development environment, not a production environment). For example, If one user is using the website to request a particular file the background script runs properly and completes the task, and make files on the server... but if multiple users try to input the file at the same time, the backend python code is run but the Django produces an error. Is there a way that each individual user will have a separate instance of the script running for them without interrupting the process of other users? In views.py file : def index(request): if(request.method == "POST"): # here I call the function of other python files to run the script # the process may take like 15 - 30 sec based on internet speed # return a FileResponce of the file to be served to the user -
How to restore default celery backend_cleanup task in django?
I'm using Django celery-beat with a Redis backend. I accidentally deleted the celery.backend_cleanup Crontabschedule, which deleted the Periodic task that was using it. How do I put them back? From the celery docs: result_expires Default: Expire after 1 day. Time (in seconds, or a timedelta object) for when after stored task tombstones will be deleted. A built-in periodic task will delete the results after this time (celery.backend_cleanup), assuming that celery beat is enabled. The task runs daily at 4am. A value of None or 0 means results will never expire (depending on backend specifications). -

Django Next.js handling responses when signing up
I am building my first Django + Next.js app and I want to display an alert when the user sign up if the username or the email already exists. Currently, if the user chooses an username/email that already exists there is a 400 error (what I want), otherwise everything is working fine. When I try it on postman, I get the explicit problem (username already exists or email already exists). But I didn't manage to achieve that on my frontend, even in the console, I don't see any message.

django: unable to save new user
I'm trying to build a view that shows a form for creating a new user. Next are the template I'm using and the code attempts at views.py and forms.py. user_form.html <form action="{% url 'app:register' %}" method="post"> {% csrf_token %} {{form.as_p}} <input type="submit" value="Register"> </form> First attempt: views.py class NewUser(generic.CreateView): model = User fields = ['username','email','password'] template_name = 'app/user_form.html' success_url = reverse_lazy('register') This one didn't return errors, but was unable to save the new user data. Second try involved creating a form for the occasion: forms.py class NewUserForm(forms.Form): username = forms.CharField(max_length=100) email = forms.EmailField() password = forms.PasswordInput() views.py class NewUser(generic.CreateView): model = User fields = ['username','email','password'] template_name = 'app/user_form.html' success_url = reverse_lazy('register') This one returned an error: TypeError at /newuser/ BaseForm.__init__() got an unexpected keyword argument 'instance' Third: forms.py class NewUserForm(forms.ModelForm): class Meta: model = User fields = ['username','email','password'] views.py class NewUserView(generic.CreateView): model = User form_class = NewUserForm template_name = 'app/user_form.html' success_url = reverse_lazy('cadastro') Can't save a new User instance either. I've also noticed that the model = User line in this last try can be removed. I'm using the User.objects.all() query in the terminal and the admin page to check for new users. What am I not doing? -

Exclude field from Django validation in admin form
I am working on project with a lot of legacy code base. I have a custom model field for price that goes like this class PriceField(PositiveIntegerField): def get_prep_value(self, value: float) -> Optional[int]: return int(value * 100) if value else self.default def from_db_value(self, value: int, expression, connection) -> Optional[float]: return value / 100 if value else value class Expertise(models.Model): price = PriceField(blank=True, default=0, help_text='Price per min.') ... Prices are stored in db multiplied by 100, e.g. 9.90 is stored as 990, and values are obtained from db in human readable way (990 as 9.90). Now I am facing a problem with default PositiveIntegerField Django admin form validation for that field. Because this value represented as float every time I click "Save" I get a PositiveIntegerField's ValidationError. Is there any way to exclude this field from admin form validation or to send this field value multiplied by 100? -
Unable to upload files/images to cloud storage (GCP) with Django
I am trying to upload files & images to the GCP bucket which I created a while ago. I am using Django rest-framework as the backend. I came across this library called [django storages][1].

Structuring multi-apps Django project to minimize import dependancies
I am trying to reorganize my project in order to minimize dependancies and get rid of potential circular imports, especially when doing the first migrations on an empty database to create the apps from scratch. To minimize those dependancies, I currently have 4 apps: puzzles (contains all info about puzzles) users (all info about users) games (everything that relates to a user performing a puzzle) puzzle_explorer (generates new puzzles) I'm however interested (for instance) by the number of users that completed a specific puzzle, so I first defined a property nb_users_who_completed in the puzzles.Puzzle model ... which leads to two-directional dependancies and potential circular imports Because in reality, there are of course a lot more models, and lot more cross-app properties, quick and dirty won't be sustainable. I've first thought about "extending" the different models (plus managers) in puzzles through Mixins: #in games: class Puzzle_Games_Mixin(object): @property: def nb_users_who_completed(self): return pass def custom_method1(self): pass # in puzzles: from games.mixins import Puzzle_Games_Mixin class Puzzle(Puzzle_Games_Mixin, models.Model) That makes the modularity more clear, but does not really help in term of solving circular imports The second strategy I thought of, is to extend in games the Puzzle model with the extra cross-application functionalities (as … -

On my web page I have an paragraph which looks like this: <p class="article-content mb-1" id="cost"><strong>Cost [Euro]: </strong>1000000</p> Number is always something else (which I read from db and represent using Django forms) and I would like to represent it as currency (in this case 1.000.000). I tried to get the value with: <script type="text/javascript"> function on_load(){ var a = document.getElementById('cost').value; console.log(a) } on_load(); </script> but Console output is: 'undefined'. When I get value, I'll use something like (12345.67).toFixed(2).replace(/\d(?=(\d{3})+\.)/g, '$&,'); // 12,345.67 To convert to currency. -

Django server not initializing with Docker?
I'm new to Docker, and I'm not being able to make it work. I'm on Windows. I cloned the repository https://github.com/18F/docker-compose-django-react, went to VSCode and built the containers with the "Remote - Containers" extension. When I try to access http://localhost:8000/, I get the message "localhost didn’t send any data.", although the React http://localhost:3000/ loads correctly. If I open the terminal from inside the Container, go to the correct folder and run python manage.py runserver, I can access it normally. So it seems that the server isn't being initialized on the Dockerfile/docker-compose. I'm also having this trouble on a setup I'm trying to make from some blog posts. How can I fix/debug this? -
Django implementation of if-else statement
I want to implement a django payment system using a payment platform named mpesa. I also want to print "hello world" on the console every time the page loads or when the request.POST.get('action') == 'post' is not triggered when the function is accessed. I have my code below. def pay_online(request): response_data = {} current_user = request.user queryset = Individual.objects.filter(user = request.user.id) if queryset.exists(): queryset = Individual.objects.get(user = request.user.id) else: queryset = Business.objects.get(user = request.user.id) if request.POST.get('action') == 'post': print("hello world 1") MpesaNo = request.POST.get('mpesaNumber') response_data['message'] = "Check your phone for ussd prompt to complete the payment." access_token = MpesaAccessToken.validated_mpesa_access_token api_url = "https://sandbox.safaricom.co.ke/mpesa/stkpush/v1/processrequest" headers = {"Authorization": "Bearer %s" % access_token} request = { "BusinessShortCode": LipanaPpassword.Business_short_code, "Password": LipanaPpassword.decode_password, "Timestamp": LipanaPpassword.lipa_time, "TransactionType": "CustomerBuyGoodsOnline", "Amount": queryset.ccTotal, "PartyA": Number, "PartyB": LipanaPpassword.Business_short_code, "PhoneNumber": Number, "CallBackURL": "https://sandbox.com", "AccountReference": "Trial", "TransactionDesc": "Trial payments" } response = requests.post(api_url, json=request, headers=headers) return JsonResponse(response_data) else: print("hello world") context = {'queryset':queryset} template = 'payments_page.html' return render(request, template, context) My main question is why this is not displaying "hello world" on the console when request.POST.get('action') == 'post' is not triggered.
