also use a reverse proxy to terminate SSL, which is what Daphne is built assuming (the SSL support in there is because it comes for free with Twisted, rather than being specifically added). Andrew On Thu, May 2, 2019 at 6:32 AM BR wrote: > I'm running a simple Django/Channels website using Da

Re: Run Daphne as non-root on low ports

In this case "reference server" merely refers to it being the place where new features and specs are implemented and tested first, rather than being the best production-capable one. I would say uvicorn is probably the best ASGI server out there right now for performance. Andrew On

Re: AutoField

Probably because you have two AutoFields. You can’t have two in the same model. Set this to eid=models.AutoField(primary_key=True) This is because Django models automatically makes an id autofield primary key if nothing else is set as pk. On Sun, May 26, 2019 at 9:05 PM Bob Gailer wrote: > On M

Re: Can we create a Rest Api in Django which can able to communicate with multiple databases(Relational, Non relational) dynamically. If yes please recommend me a way to do that

There really isn’t any point in doing that. 1) You should just use one of the two. Django officially supports Postgres. 2) You’d want to keep your users all jumbled in one database. If you have a foreign key to the username field, and the db can’t find a specific user because it’s in the other db,

Re: Internal Ranking System Application

Gotcha. I’ll try my best to explain what you could try. And if this looks sloppy, then I’ll make a public gist. So, firstly, let’s set some things straight. A database is a collection of tables. Models in Django represent one table with multiple columns. Tables do not need to have the same columns

Np! https://docs.djangoproject.com/en/2.2/ref/models/fields/#floatfield Just refer to the docs. There’s FloatField and DecimalField for models. When you show the numbers in views, just use python to round the numbers. There are plenty of tutorials and SO (stackoverflow) questions that’ll help. Pe
