Deep Learning Model calling through FAST API
Is it possible to call a deep learning model which is working on several GBs of data to be called through an api which is made by Fast API? Or would DjangoREST or Flask be a better approach? -
How to prevent race condition while working with sessions?
I’m working on an e-commerce website with a cart and products. A product’s primary key is added to the user’s session data in a dictionary 'cart_content'. I successfully reproduced a race condition bug by triggering a click() twice with an amount of product that will sold out for the next purchase. So the two requests increment twice the cart but there is not enough stock. How can I prevent race condition to happen like the example given above or in a multi-user case ? Does there is for example some sort of lock system that prevent add_to_cart() from being executed asynchronously ? core/models.py : class Product(models.Model): … number_in_stock = models.IntegerField(default=0) @property def number_on_hold(self): result = 0 for s in Session.objects.all(): amount = s.get_decoded().get('cart_content', {}).get(str(self.pk)) if amount is not None: result += int(amount) return result … cart/views.py : def add_to_cart(request): if (request.method == "POST"): pk = request.POST.get('pk', None) amount = int(request.POST.get('amount', None)) if pk and amount: p = Product.objects.get(pk=pk) if amount > p.number_in_stock - p.number_on_hold: return HttpResponse('1') if not request.session.get('cart_content', None): request.session['cart_content'] = {} if request.session['cart_content'].get(pk, None): request.session['cart_content'][pk] += amount else: request.session['cart_content'][pk] = amount request.session.modified = True return HttpResponse('0') return HttpResponse('', status=404) cart/urls.py: urlpatterns = [ … path("add-to-cart", views.add_to_cart, name="cart-add-to-cart"), … -
Cannot login on my website with a user I create in django admin
I have a login and signup page, where a user that signs up is able to login and i can view this user in the admin portal as shown in the screenshots below: Example User created through signup page: Username=usertest Password=pass123 Signup page Signed up user visible in admin portal (note: password is hashed) However, when i create a user in admin portal I cannot login with that user in login. This may be due to the password that is being stored as it is not hashed when viewing admin portal-not too sure: Example User created through django admin portal: Username=usertest2 Password=pass1234 User created via admin portal (note: password is not hashed) Login says invalid despite user present in admin view I have tried to have a look and think it might be the password is not hashed when creating a new user in admin portal and so when login is compared this might be causing the issue- not too sure. Below are my codes, I can share further code that can help solve this too: models.py from django.db import models from django.contrib.auth.models import AbstractUser class User(AbstractUser): username = models.CharField(max_length=50, unique=True) profile_pic = models.ImageField(null=True, blank=True, upload_to="images/profile-images") date_of_birth = models.DateField(null=True, blank=True) … -
How do i get these crsf token for a drf api without frontend?
Hi I am new to Django Rest frameworks and I am making a api for a mobile app which will make post request to the Backend so the thing is I am getting a response from the request which is { "error": "CSRF token missing" } And I tried to see BardAi and ChatGPT they said that it would only work if I have a front end framework dealing with these cookies so is that a solution to get the token without using the decorator which would exempt the token all in itself. I would like source code and any solutions. -
How to render in real-time one of the fields of the Django model?
I already set up the connection between the server side which are the asgi.py, consumers, and routing, that is already listening to client side using javascript. But I don't know how to render out, in real time, the field in that one model to my javascript that'll will be shown in HTML. I'm not trying anything for now since I do not know where to start, and what to do. But all I want to achieve is to render that one field from the model through the HTML in real time. -
Running django project using pm2 and gunicorn fails with syntax error I cant fix

AWS Django NGINX timeout and async errors
I have a view in which I try to upload an excel sheet via a form. The excel that I upload isn't that big but the processing of the data in that excel is causing nginx time out issues resulting in a 502 Bad Gateway error. I do not have this problem when testing locally but it pops up on AWS EC2 when testing it on that environment. I increased the time out periods in nginx via (as suggested here): proxy_read_timeout 300s; proxy_connect_timeout 300s; proxy_buffer_size 128k; proxy_buffers 4 256k; proxy_busy_buffers_size 256k; And that did improve things somewhat since I can see more results but it was not sufficient. Curiously it timed out again before the 300s were up. Incidentally, if it used all 300s it should complete the process. It was also suggested I use async to make the processing independent of the upload process and that it run the processing in the background. However in attempting I keep running into this error: "object HttpResponseRedirect can't be used in 'await' expression" This error occurs when I try to load the page even before I try to upload the excel file which is the only time I have a redirect, which … -

Issues with Django Import-Export: Validation Errors during CSV Import
I am currently working on a Django project where I'm using the django-import-export library to import CSV data into my models through the Django admin interface. I have set up resources, models, and made necessary changes in the admin, but I'm facing validation errors during the import process. I have the following structure in my Django project: models.py: Contains the definitions of various models like PlayStyles, Coaches, Stadiums, Leagues, Teams, Players, Matches, and Statistics. resources.py: Includes corresponding ModelResource classes for each model. admin.py: Configures the Django admin interface to use the ModelResource classes for data import/export. CSV Files: I have CSV files for each model with data to be imported. Despite setting up the resources correctly, I am encountering issues when importing CSV files for certain models, specifically for Teams. The error message mentions validation errors related to foreign key fields (stadium, coach, and league). Here's a snippet of my relevant code: models.py: # ... (models for PlayStyles, Coaches, Stadiums, Leagues, etc.) class Teams(models.Model): name = models.CharField(max_length=100) established_year = models.IntegerField() stadium = models.ForeignKey(Stadiums, on_delete=models.CASCADE) coach = models.ForeignKey(Coaches, on_delete=models.CASCADE) league = models.ForeignKey(Leagues, on_delete=models.CASCADE) number_of_titles = models.IntegerField() resources.py: # ...

Create django filter choices based on current queryset
I have a table with a number of category columns and I want to provide a choice filter for each category column based on the current set of values, not based on all possible values. year category_a category_b 2020 x a 2021 y b 2022 z b Given the above the initial choices for category_a would be x,y,z and category_b would be a,b. This I can achieve by using something like self.parent.queryset.distinct('category_a'). However once the user applies a filter like category_b=b, the choices should only be y,z, i.e. something like self.parent.qs.distinct('category_a'). This however runs into recursion. I'm looking through the execution path of FilterSets, since it seems to me that they must be used twice in a request, once to apply the current filter data and a second time to render the filter widgets for the response, but choices is evaluated as part of the initial set validation, hence the recursion. Is there a way to defer the computation of choices until the widget is rendered? -

cannot install mod_wsgi on windows over wampserver 3.3.2 6rbit
I have been trying to install mod_wsgi using pipenv install mod_wsgi on windows machine over a wampserver, but I get this error. I searched google for info on proceeding getting a Django app hosted over Apache, but couldn't find any information (or a resolution). They all mention to install mod-wsgi using "pip install mod-wsgi", as it is tried and tested, but each time I try it, I get this error below. Any suggestions to overcome this would be helpful. Thanks. (spolls-JBTzETyl) C:\spolls\polls>pipenv install mod_wsgi Installing mod_wsgi... Resolving mod_wsgi... Added mod-wsgi to Pipfile's [packages] ...
