django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet with Django’s user database authentication from Apache
I have created a django project with only one application. I haven't made any changes in the application. Only added the application to the settings and updated static and media urls. Migration is done and super user was created. I have configured apache(version:2.4.29) and mod_wsgi(4.5.17) according to Authenticating against Django’s user database from Apache.

Conflict between python-slugify and awesome-slugify
I am using the awesome-slugify python library (1.6.5) but for another Django app I need also to use the csvkit python library (version 1.0.3). Once I install the csvkit (pip install csvkit), I start getting an error when importing the Slugify. I figured out, that this is cause csvkit also required the python-slugify (2.0.1) in order to work. There is a conflict between awesome-slugify and python-slugify. In the past I have used all 3 together without any issue. The versions I have used were the following: python-slugify: 1.2.4 csvkit: 1.0.0 awesome-slugify: 1.6.2 I thought I could solve the issue by doing: pip install csvkit==1.0.0 <-- this still installs the latest python-slugify pip install python-slugify==1.2.4 pip install awesome-slugify==1.6.2 But unfortunately it doesn't seem to work. Cause somehow the two slugify libraries share the same folders. The problem is that python-slugify is installed as a dependency of the csvkit. So its not straightforward to me, how I could define the folder name of the insllation inside the site-packages.. What a mess.. -
How to enforce logger format during Celery task execution?

How to avoid end user actions based on stale data in DB
I have a database table at the backend, that provides various items for sale and their prices as well. For the sake of simplicity, let us assume that the schema for the same is like so:- class Product(models.Model): item_id = models.Integer() item_name = models.CharField(max_length=30) item_price = models.CharField(max_length=30) item_count = models.Integer() There is an API getProducts(), that is used to show to the enduser all the products available, including their price. There is another API buyProduct(product_id), exposed to the enduser, using which he may purchase the item after seeing its price. There is a third API, updatePrice(product_id, new_price) available to the administration backend using which the price may be modified. Now w/o having a database transaction that spans across >1 HTTP requests, how can I ensure that the API buyProduct() succeeds only if the price is the same as what the enduser saw (basically whatever getProducts() had returned last to the browser). It is possible that a customer sees the price of a product as 1$, and clicks BUY, but simultaneously the price at the backend was changed to 2$. I have two solutions:- Fix the buyProduct() API to include a price, which indicates whichever price that was shown to the … -
Django separate settings files in Docker
Following multiple articles around the web, I've split my Django 1.11 settings.py file into multiple files, base.py, local.py, staging.py, production.py, in a settings folder. The Django app runs in a Docker container. docker-compose.yml: django: build: context: . env_file: .env command: ["/wait-for-it.sh", "mariadb:3306", "--", "/gunicorn.sh"] In the Dockerfile I export the DJANGO_SETTINGS_MODULE as the local settings file (which in turn imports the base.py settings file). Dockerfile: FROM python:3.6.4 RUN mkdir /app ADD requirements/*.txt app/requirements/ RUN pip install -r mira/requirements/dev.txt ADD . /app RUN export DJANGO_SETTINGS_MODULE=app.settings.local RUN export DJANGO_SECRET_KEY=dummy-secret-key COPY ./docker/web/entrypoint.sh ./docker/web/gunicorn.sh ./docker/web/wait-for-it.sh ./docker/web/logging.conf ./scripts/setup.sh / RUN chmod +x /entrypoint.sh /gunicorn.sh /wait-for-it.sh /setup.sh WORKDIR ./app settings/base.py: SECRET_KEY = os.environ['DJANGO_SECRET_KEY'] .env: DJANGO_SECRET_KEY=FOOBAR When I try to up the container, I get this error: The SECRET_KEY setting must not be empty. -

"Django not found" using venv in Eclipse/PyDev
I'm having trouble setting up Eclipse IDE for JavaScript and Web Developers (version 2018-12 4.10.0) with PyDev to use Django from a virtual environment. I'm using Ubuntu 18.04. TL;DR: when I create a new Django project in PyDev, Eclipse doesn't find Django, although it is installed in the venv. Details: My workspace structure is as follows: └── workspace └── djangogirls ├── mysite ├── djvenv ├── manage.py ├── db.sqlite3 └── requirements.txt I set up the virtual env with python3 -m venv djvenv I installed Django~=2.1.5 from requirements.txt using pip install -r requirements.txt I activate the venv in shell and test Django is installed (returns '2.1.5') source djvenv/bin/activate django-admin --version In Eclipse, I create a new workspace in directory workspace; installed PyDev and activated its perspective in Window>Perspective>Open perspective>Other>PyDev.

Django: how do you deal with queries that can not scale?
In my code, I have a few queries that are not scalable at all. For example, take a look at this code: class OrderQuerySet(query.QuerySet): def for_day(self, day: date): """ Return all orders that concerns the given service day """ day_order_pks = [order.pk for order in self.all() if localdate(order.service.start) == day] return self.filter(pk__in=day_order_pks) At the beginning, it perfectly worked. The problem is, when order amount increase, the performance seems to decreases in a linear way, which makes senses because all orders need to be tested each time. Having 1000 new orders every day, it's obvious my system will not be usable anymore in a few time! Usually, how do you deal with this kind of problem in Django? I mean, sometimes I can find a trick to write a better query, using Django ORM only. But sometimes, to get what I want, I seems to be forced to create my queryset this way, using Python and a for loop. -
Django: How to get select2 to start working, basic hello world
I would like to use select2 in Django to create a multi-select combobox (pillbox), such as: However, my result looks like: Efforts: I have downloaded, as well as tried to link directly to CDN <link rel="stylesheet" type="text/css" href="{% static 'product/lib/select2/css/select2.min.css' %}"> <script src="{% static 'product/lib/select2/js/select2.min.js' %}"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/css/select2.min.css" rel="stylesheet" /> <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.6-rc.0/js/select2.min.js"></script> I have also, step by step, trying to identify the problem, as well as analysing and comparing in the browser using the inspector. I do not use Bootstrap (save for importing some functionality from the js) and cannot see it is related to the conflict mentioned in some forums and on the help page for select2. Using the basic example on https://select2.org/getting-started/basic-usage, produces the same result. Its like it cannot "activate", despite using the script and checking linkage. What could be the problem? I'm using Django 2.1.5, Python 3.6, and latest select2 (both css and JS, header and near bottom of body) -

Unable to get django declared app routes working as pages
I am creating an Django app and am facing issues with routes not being identified. It is the same DJango poll app I am trying to create but the documentation code does not work. Here is my code below: djangoproject/urls.py from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^simpleapp/', include('simpleapp.urls')), url(r'^admin/', admin.site.urls), ] simpleapp/views.py from django.shortcuts import render from django.http import HttpResponse, request def index(request): return HttpResponse("Hello, world. You're at the polls index.") def detail(request, question_id): return HttpResponse("You're looking at question %s." % question_id) def results(request, question_id): response = "You're looking at the results of question %s." return HttpResponse(response % question_id) def vote(request, question_id): return HttpResponse("You're voting on question %s." % question_id) simpleapp/urls.py from django.conf.urls import url from . import views urlpatterns = [ # ex: /simpleapp/ # url('', views.index, name='index'), # ex: /simpleapp/5/ url('<int:question_id>/', views.detail, name='detail'), # ex: /simpleapp/5/results/ url('<int:question_id>/results/', views.results, name='results'), # ex: /simpleapp/5/vote/ url('<int:question_id>/vote/', views.vote, name='vote'), ] If I un-comment the first url of '' path of simpleapp/urls.py code, all the pages shown are '' path. However, if I keep the url '' path commented, then the routes give me the following error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/simpleapp/34/ …
