Tests not running - Postgres database not connect via circle ci
I am running a Django project and I have set up tests and wanted to run them through circle ci. However, when I push my code to GitHub. Circle CI can't seem to connect the database. This only started when I introduced a .env file and python decouple What is the best way to setup environment variables that I need for development and the same time for Circle CI? I have tried creating seperate settings config files.

Reuse queryset in multiple views
I am building a application which has several views - HomePageView, SearchPageView and DetailPageView. The aforementioned views return the same queryset. My question is, what is the proper way to define let's say a "global" queryset which would be then used in multiple Views. To illustrate my point here is an example of what I have: class HomePageView(TemplateView): def get_queryset(): return Systemevents.objects.filter(**filter) class SearchPageView(ListView): def get_queryset(): return Systemevents.objects.filter(**filter) class LogDetailView(DetailView): def get_queryset(): return Systemevents.objects.filter(**filter) What I would like to achieve: global queryset = Systemevents.objects.filter(**filter) class HomePageView(TemplateView): def get_queryset(): return queryset class SearchPageView(ListView): def get_queryset(): return queryset class LogDetailView(DetailView): def get_queryset(): return queryset Thanks in advance, Jordan -

Django Channels - Channel Layer?
I am newbie in web development and learning mostly Django and Vanilla Javascript, CSS for now. I got confused while reading the docs about Django Channels. In tutorials it is written that Channel Layer is like kind of a router which passes HTTP request to views and Websocket traffic to Consumers and Redis is mostly used for Channel layer. As I mentioned I am kind of newbie in development and never used Redis. The thing I understood from reading couple of posts that Redis is used as cache for lowering the load on database accesses. So my question is: What is relattion of Channel Layer and Redis. If Redis is a caching technology, how it is used as router for requests? -

Paginating AJAX results on a Django Template
I have a basic Django template that displays the objects in the database and I have used Django's pagination and it works just fine. However, I have a sort functionality on the template that is tied with an AJAX function that updates the template based on the choice picked.

Working with Mapbox JS in a Django project
I am working with a MapBox JS map element in a Django project, and the intention is to use the returned map result to query an SQLite3 database. My question is whether I am best placed to work with JS to query my database, or whether I can pass the JS variable/s to an existing function I have within my views.py which does the database lookup. If the latter, I would appreciate any advice/instruction on how to go about doing this. -
