Using pytest to test django packages
I have created a Django package (a Django App) that adds functionality to Django when installed and referenced in settings.py INSTALLED_APPS of the Django project. I am familiar with writing tests for Django using pytest, and the pytest-django plugin. As the pytest-django plugin provide fixtures such as a web client to interact with the django project. However I never wrote tests for a Django package. How do I use pytest and pytest-django plugin to test my Django package, without having a real django project that has settings.py that loads the package? -

Set table width with pandas set_table_styles
I'm trying to set the table width using set_table_styles, but it doesn't work. I tried to find information about this in the documentation, but there is no example there. I looked into this issue, but it didn't help either. https://stackoverflow.com/questions/74046791/set-width-to-100-fill-container-with-pandas-set-table-styles Part of my code: turnover = pd.pivot_table(data_for_turnover, columns=['Date'], values=['Turnover', 'Sales', 'Stocks'], aggfunc='sum') table_style = {'selector': 'table','props': [('width', '100%')]} turnover = turnover.style.format('{:.0f}') turnover.set_table_styles([table_style]).to_html() Next I display using Django, but the width (I also tried change border, margin) does not change. If I try to change the th or td styles, they are applied. Please help me find, if not a solution, then a reason. -
Django Channels Web Socket Connection Keeps Closing
I created the following consumers in my django application to handle real time notifications: class NotificationConsumer(AsyncWebsocketConsumer): async def connect(self): self.room_name = f"notification_{self.scope['url_route']['kwargs']['user_id']}" await self.channel_layer.group_add(self.room_name, self.channel_name) await self.accept() # other methods below and i have my routing to this consumer here: from django.urls import re_path, path from .consumers import NotificationConsumer websocket_urlpatterns = [ path('notification/<int:user_id>/', NotificationConsumer.as_asgi()), ] Then i am connecting to this in the frontend with javascript: const websocketProtocol = window.location.protocol === "https:" ?

Why doesn't my Django app work, 404 Page not found
I know somebody has asked this question this is the link to it, but none of the solutions there worked for me so I had to open a new question. When I run my code I get this error message: Using the URLconf defined in storefront.urls, Django tried these URL patterns, in this order: admin/ playground/ The empty path didn’t match any of these. here is my storefront urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('playground/', include('playground.urls')), ] and here is my playground urls.py: from django.urls import path from . import views # URL conf module urlpatterns = [ path('hello/', views.say_hello) ] also here is my playground views.py: from django.shortcuts import render from django.http import HttpResponse def say_hello(request): return HttpResponse('Hello World') Can somebody tell me what could be the problem?

Optimizing Video Load Times on Mobile(Django)
I'm currently developing a website for a client, which serves as a platform for uploading and showcasing videos to their customers. The site features seven short videos (each under 1 minute) on the landing page. However, I've encountered a loading speed issue when accessing the site on mobile devices; the videos load quite slowly despite a fast internet connection. This issue doesn't occur on PC. The website is hosted on an Ubuntu VPS and is dockerized. Does anyone have suggestions on how to optimize the loading speed for mobile devices? Any advice would be greatly appreciated. I implemented lazy loading for the videos, hoping this would enhance the loading speed on mobile devices. Despite this implementation, the loading speed on mobile remains considerably slow, which is not the case on desktop. -
Wagtail, can't add settings
I'm trying to add custom settings to wagtail (version 4.0.4). Following the guide from the docs, I added wagtail.contrib.settings to INSTALLED_APPS and added this to models.py: from wagtail.contrib.settings.models import register_setting, BaseGenericSetting from django.db import models @register_setting class Authors(BaseGenericSetting): facebook = models.URLField() Then made makemigrations/migrate. But nothing appeared in Wagtail settings. Then I tried to register model in admin. In wagtail_admin.py from wagtail.contrib.modeladmin.options import ( ModelAdmin, modeladmin_register, ) from .models import Authors @modeladmin_register class AuthorsAdmin(ModelAdmin): model = Authors list_display = ("facebook",) add_to_settings_menu = True menu_label = "Authors" But still the same result. What do I miss? Some extra config or ...? Only after removing add_to_settings_menu = True, Authors appears in the side-menu (but, of course, not in the settings). With this line - nothing. -

Getting code coverage 0% despite getting print statements in Django development server
I have a django project running on local development server. It has different remote DB server. I am trying run API integration tests. Tests are running and giving expected output.

AddEventListener is executed twice
I am working with Django and Js, and I am trying to get the code to switch the checked attribute of an element so that it changes the category during the creation of an entry in the form, but when clicking on the element, addEventListener is executed twice and, thus, first adds the checked attribute to the element but then immediately removes it Code: form <div class="new-post-header"> <div class="new-post-functions"> <button type="submit" class="save"><ion-icon name="checkmark-outline"></ion-icon></button> <div class="categories"> <div class="first-category">{{ form.category.0 }}</div> <div class="second-category">{{ form.category.1 }}</div> </div> </div> </div> <div class="new-post-content"> <div class="new-title">{{ form.title }}</div> <div class="new-description">{{ form.description }}</div> </div> js secondInput.hasAttribute('checked') ? localStorage.setItem('secondInput', true) : localStorage.setItem('secondInput', false) secondLabel.addEventListener('click', function() { let secondInputItem = localStorage.getItem('secondInput') if (secondInputItem === 'false') { firstLabel.innerHTML = `<input type="radio" name="category" value="1" required="" id="id_category_0"><ion-icon name="bookmark-outline"></ion-icon>` secondLabel.innerHTML = `<input type="radio" name="category" value="2" required="" id="id_category_1" checked="checked"><ion-icon name="archive-outline"></ion-icon>` localStorage.setItem('secondInput', true) console.log(true) } else { firstLabel.innerHTML = `<input type="radio" name="category" value="1" required="" id="id_category_0" checked="checked"><ion-icon name="bookmark-outline"></ion-icon>` secondLabel.innerHTML = `<input type="radio" name="category" value="2" required="" id="id_category_1"><ion-icon name="archive-outline"></ion-icon>` localStorage.setItem('secondInput', false) console.log(false) } }) -

Django + Celery + SQS - Messages not received by celery worker?
I'm trying to implement background tasks on my Django web app using Celery and AWS SQS as the message broker. I have a view which calls a task, which is sent to SQS successfully.

Django Refresh Token Rotation and User Page Refresh
I'm using Django simple JWT to implement user authentication, I have done few adjustments so the access token and refresh token are sent as http-only cookies and everything works well On the frontend I have implemented Persistent Login that would keep the user logged in when they refresh the page or close the browser etc. But since I have enabled these settings: "ROTATE_REFRESH_TOKENS": True, "BLACKLIST_AFTER_ROTATION": True, If the user keeps refreshing the page multiple times in a very short time, it might occur that a token is blacklisted before the user receives the new refresh token is there a way to fix that? One possible fix yet I'm not sure of its reliability is disabling the automatic blacklisting and waiting for the frontend to send a request upon receiving the new refresh token, the request containing the old refresh token in its body like this @api_view(['POST']) def blacklist_token(request): refreshToken = request.data.get("refresh") print(refreshToken) if refreshToken: token = tokens.RefreshToken(refreshToken) token.blacklist() return Response(status=status.HTTP_200_OK) PS: Using React.js on the frontend -
How to update Django model fields after filtering by id?
I want to write a function that, when executing a "GET" request, will change fields such as: "inaction" and "lastAction" to 2 and the datetime.now(). But when I wrote my code for the first time, I encountered an error: TypeError: cannot unpack non-iterable int object. This code: def update(self, res_id: str): user, updated = User.objects.filter(id=res_id).update(inaction="2", lastAction=datetime.now()) code_status = HTTPStatus.ACCEPTED if updated else HTTPStatus.OK.value return user, code_status For this reason, I rewrote my code to the following and that started works: def update(self, res_id: str): updated_rows = User.objects.filter(id=res_id).update(inaction="2", lastAction=datetime.now()) user = User.objects.filter(id=res_id).first() code_status = HTTPStatus.ACCEPTED if updated_rows else HTTPStatus.OK.value return user, code_status But in this code, I'm worried about duplicates of the form: User.objects.filter(id=res_id). How can I avoid them? -

Deploying Django project in an Amazon EC2 Ubuntu instance
I have developed a Django website and hosted the application in an Amazon EC2 instance. AMI name: ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-amd64-server-20231207 Instance type: t2.micro I run the project following these steps: SSH into the EC2 instance from my terminal. I locate into the proper django project folder. I run this command: python3 manage.py runserver 0.0.0.0:8000 Now, following these steps, I'm able to run the project and it works fine. But when I close the cmd opened in my local PC that I used to SSH into the EC2 instance and to run the application, then the application doesn't work anymore. My aim would be to simply run the django project from my cmd once (of course after having SSH to the EC2) and then close my laptop and having the application still alive. Do you know how can I do this?
