How to load static css file inside extended template
I have a base.html file which contains the base of all of the HTML pages. I want to create 404.html page: {% extends 'base.html' %} {% block title %} Page 404 {% endblock title %} {% load static %} <link rel="stylesheet" type="text/css" href="{% static '404_style.css' %}"/> {% block content %} <!-- HTML code here --> {% endblock content %} The tree: ./app/app |-- ./app/app/settings.py |-- ./app/app/static | |-- ./app/app/static/404_style.css | `-- ./app/app/static/style.css |-- ./app/app/templates | |-- ./app/app/templates/404.html | |-- ./app/app/templates/base.html | |-- ./app/app/templates/homepage.html |-- ./app/app/urls.py |-- ./app/app/views.py I don't understand why it does not load 404_style.css. My guess is that it is not inside the head tag (which is in base.html. So I tried to add {% block extra_head_content %}{% endblock %} inside the head tag inside base.html but it does not work. How can I load static css file inside extended template? -
Sort objects by interaction time grouped by users in Django
I have a Django app (I use Postgresql for the database), and I have these models of Customers, Products and Transactions that are connected as follows: class Customer(models.Model): products = models.ManyToManyField(Product, through='Transaction') class Product(models.Model): ... class Transaction(models.Model): customer = models.ForeignKey(Customer, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) transaction_timestamp = models.DateTimeField(auto_now=True) The transaction model tracks the time when a customer interacted with a product. I have a list of user ID-s users. I want to get a list of say 1000 products they last interacted with for every customer in users. Is there any way of doing this faster than iterating all the users? I assume this might be done through Aggregation somehow, but I couldn't find anything that worked in my case. -

How to install cruds_adminlte correctly?
I'm going round in circles here.

How to set daily Update limit on Django model
I'm new to Django. I have created one Django App where users can update their Shift Timing(Morning/Evening/General) and based on this Shift Timing I am taking real-time data from Django Model and running Linux script which will be evaluating user shift timing and allowed timing to use the application. I have used Django import and export which allow the user to upload multiple users' data by using a .xls file from the front-end. Now here I want to apply some limit for example suppose my model is having 5000 records so I want that only 50% of its records should be allowed to modified whether it is added through .xls file or by clicking on update single records(I am doing this because I don't want that more than 50% of users should update Shift Timing). Is there any easiest way to implement this requirement? I have checked https://pypi.org/project/django-limits/ (django-limits 0.0.6)but did not understood from step 3. I am adding my models.py class CTS(models.Model): AConnectID = models.CharField(max_length=100,) Shift_timing = models.CharField(max_length=64, choices=SHIFT_CHOICES, default='9.00-6.00') EmailID = models.EmailField(max_length=64, unique=True, ) Vendor_Company = models.CharField(max_length=64, ) Project_name = models.CharField(max_length=25, default="") SerialNumber = models.CharField(max_length=19, default="") Reason = models.TextField(max_length=180) last_updated_time = models.DateTimeField(auto_now=True) class Meta: ordering = ['-id'] def … -
IntegrityError UNIQUE on blog_post.slog despite creating unique slug function
I am new to django and somewhat new to python too. I am trying to create a simple blog application and as we all know you want to have unique slugs for your blog links. However I cannot seem to rid myself of this UNIQUE error. Problem description When I create a blog post I create a slug from the title. Then I see if that slug matches any others in the database. If it does, I add a little string to the end. Nevertheless, the database keeps throwing an IntegrityError. What I've tried I have been using import pdb; pdb.stack_trace() to try to trace the issue. It seems to me to happen after setting self.object.slug and then doing self.object.save(). Somehow the unique slug is may not be be being passed to save.(). But I'm not sure how to debug beyond this point. I'd appreciate help in the debugging process. The confusing thing is that I'm working from a (functioning) django blog app. I cannot find the difference between my code and that one, and I've tried changing the methods.py and views.py to match that of the other blog, and yet that app produces unique slugs and throws no errors, … -

Calling other docker container by name doesn't work when using Nginx (Docker, Django, React/Next.js)
I am working on a project with Docker using Django in the backend and Next.js in the front. I currently have it working without using Nginx by binding the ports of each container to the host machine's port 8000 and 3000 respectively, with the Next.js's serverside calling from environment variable set as 'backend:8000/users/auth_api/google/' for authentication (backend is the container name for the backend). However, upon including Nginx, it doesn't seem to work anymore. I had to include a '/backend/' prefix to my backend container with the proxy_pass setting as I intend for the root '/' to be for the frontend. I've tried setting different environment variables and verified that uri call from the serverside from the logs but it just doesn't reach the backend (logs show that the api call to the environment variable uri was made by the frontend but not received by the backend meaning the api uri is wrong). Environment variables I've tried: SS_BACKEND_GOOGLE_AUTH=http://0.0.0.0:8000/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://0.0.0.0:8000/backend/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend:8000/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend:8000/backend/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend/users/auth_api/google/ SS_BACKEND_GOOGLE_AUTH=http://backend/backend/users/auth_api/google/ Docker-compose file version: '3.8' services: backend: restart: unless-stopped build: context: ./backend dockerfile: Dockerfile.test command: sh entrypoint.prod.sh container_name: backend expose: - 8000 ports: - 8000:8000 volumes: - ./backend/:/usr/src/backend/ - static_volume:/usr/src/backend/staticfiles - media_volume:/usr/src/backend/mediafiles env_file: - ./.env.test depends_on: - db - … -

I'm learning django and testing how it works with API and currently I'm trying to display records from an localhost API, but it seems like I missed something def fetchapi_patients(request): url = 'http://localhost:8000/core/users/roles/superuser' headers={"Authorization":"Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2MDYzMDg3MzYsImlkIjoiYWRtaW4iLCJvcmlnX2lhdCI6MTYwNjMwNTEzNn0.J2wBp8ecA9TebP6L73qZ1OZmo02DwQy9vTySt0fil4c"} response = requests.get(url, headers=headers) #Read the JSON patients = response.json() #print(patients) #Create a Django model object for each object in the JSON and store the data in django model (in database) for patient in patients: #print(patient['ID']) Patient.objects.create(first_name=patient['first_name'], last_name=patient['last_name'], email=patient['email'], coreapi_id=patient['ID'], created_date=patient['CreatedAt']) return JsonResponse({'patients': patients}) #return HttpResponse('ok') I tried different thing to make it work and I end up to test if it prints something with print(patients) and this gives the list in the terminal from my localhost API, and I found that the API works, but can't find why they don't printed in my frontend part of the websystem.

Get initial value on nested serializer with many=True
class SomeSerializer(ModelSerializer): class Meta: fields = ("currency", "amount") model = SomeModel def get_amount(self, value): if getattr(self, "initial_data", None): currency = self.initial_data.get("currency") # for a case when serializer used directly else: currency = self.root.initial_data[self.source]["currency"] # for a case when serializer is nested # do some stuff return amount My serializers works fine, bith when is's used directly or as nested serializer. Here is serializer that uses previous one as nested: class OperationSerializer(Serializer): ... operation = SomeSerializer() Everything works fine until I try to use OperationSerializer with many=True. In this case I cannot get initial value of currency, because I need to specify an index for the root element which is not known for me. -

whats the most sensible way of keeping the current user when using mobile auth on login?
I want mobile auth on login, but am wondering what the best way would be to store the current user, before giving them a session id (which would be granted on successful mobile auth). does it make sense to store a jwt in cookies for the user after they enter their password, while they're on the 2fa auth page? I've looked at a few sites with 2fa, and cant see any that do this, so figure there must be a better way? -
Django RecursionError on A2 Hosting server with basic project
I recently set up Python hosting for my Django application. I used A2Hosting with cPanel, and followed these instructions that they gave. So now I have a Django project and application, with a few modifications they asked for; I can confirm that the app is running, but… Now I'm doing the standard procedure, creating a simple HttpResponse view, creating an app-local urls.py, linking that urls.py to the project-wide urls.py, and removing this url block that they had me use, which WORKS, but I really don't want to render the templates raw like this: url(r'^$', TemplateView.as_view(template_name='static_pages/index.html'), name='home'), Well now I'm getting this error: (DOMAIN, APP, and USERNAME removed for privacy) RecursionError at / maximum recursion depth exceeded while calling a Python object Request Method: GET Request URL: http://APP.DOMAIN.TLD/ Django Version: 3.1.4 Exception Type: RecursionError Exception Value: maximum recursion depth exceeded while calling a Python object Exception Location: /home/USERNAME/virtualenv/APP/3.7/lib/python3.7/site-packages/django/urls/resolvers.py, line 258, in match Python Executable: /home/USERNAME/virtualenv/APP/3.7/bin/python Python Version: 3.7.8 Is my version too high? I assumed the documentation just used lower numbers because it hasn't been updated in a while. -
