Re: Integrate dj-database-url into Django

2018-07-28 Thread Luke Murphy

I'd love to see native dj-database-url support in Django. I suppose it
would have to support all the back-ends, no? It might lead to confusion
otherwise.

  I'd like to approach this as 'support database urls in django', rather
  than 'copy/paste dj-database-url into django'. For postgres (I'm not sure
  about other backends), a database url can be passed directly to psycopg2.
  The postgres connection string format actually supports more features than
  is possible with django's HOST/USER/PORT... style settings. For example,
  you can pass multiple hosts and psycopg2 will attempt to connect to one of
  them: https://paquier.xyz/postgresql-2/postgres-10-multi-host-connstr/.
  Any attempt to parse the url in django will result in a loss of those
  features.
  The only problem I see is that we have to parse the database backend out
  of the url, and you can't pass a url like 'postgis://' to psyscopg2.
  I'd like to be able to do something like:
  DATABASES = {
      'default': {
          'DSN': 'postgres://',
          'ENGINE': 'django.contrib.gis.db.backends.postgis',
      },
  }
  And let psycopg2 handle the DSN.

Re: Type hints, PEP 561, and mypy-django

FYI we're chatting on https://gitter.im/mypy-django/Lobby about organising this.

Feel free to drop by there.

Hi folks,

Following a short discussion over at:


https://github.com/machinalis/mypy-django/issues/9,


There is some renewed interest in getting stuck into type hints for
Django. I wanted to drop a mail here to see what the status is.

In preparation for this email, I've been combing the Django issue
tracker and some related project Github issues to see what has already
been done and adding notes over at:


https://github.com/lwm/mypy-django/issues/1


Was I correct in discovering that there is some general consensus on
waiting PEP 561 to land? It seems like that PEP has been accepted and
there are three options for implementation:


PEP 561 notes three main ways to distribute type information. The
first is a package that has only inline type annotations in the code
itself. The second is a package that ships stub files with type
information alongside the runtime code. The third method, also known
as a “stub only package” is a package that ships type information for
a package separately as stub files.


I saw mention of the necessity of DEP being submitted.  Has it been
done yet or started? I can't see anything related over at:


https://github.com/django/deps


Hope someone can enlighten me, thanks!

Best,

Luke
