I'd adopted this codebase with every intention of being a good maintainer, but that's clearly not happening. There's a backlog of issues I'm unable to get to, and it's clearly leading to some frustration. So, I'm taking the nudge of Volunteer Responsibility Amnesty Day and looking for new maintainers.

If you'd like to pick up maintaining this repo, leave a comment here and let me know. I'll check back in a week or so and do the logistics.

I am mildly wary of supply-chain attacks, so I do have a few requirements to try to protect our users:

1. If more than one person step up I'd like y'all to coordinate creating an organization to transfer this repo to; if it's just a single person I can transfer it to your personal github or a repo, either way.
2. Anyone who's going to be a maintainer needs at least a bit of history here on github -- I won't be ok transferring this to a new account.
3. I'd like you to commit to cutting a new release within a month or so, as a way of notifying users that the ownership has changed. I'll grant you access to PyPI to do the release, but I'll also keep access; I'll had that last bit over once this new release goes out.

Sorry I haven't been a good steward; I'm sure the next folks will do better!

Project details

If the password contains special characters such as ? or /, the following exception is raised (here I tried to use "foo?bar" as a password):

I tried to escape the special characters with backslashes but then it got interpreted as "foo". I also tried to url-encode them, ie. replacing "?" by %63 but then the password returned by dj-database-url was "foo%63bar".

The issue can be easily reproduced with the following URL: postgres://foo:foo?bar@localhost/foobar.

Maybe I'm just missing something but if that's the case I think it would be worth documenting it somewhere.

Given the widespread use of dj-database-url, it seems a good idea for it to become Official Project, per DEP 7. Maintenance burden seems minimal but important.

Read DEP 7 for full details, but roughly there are 4 steps:

1. Pre-proposal discussion
2. Form a team
3. Formal proposal
4. Django Technical Board Vote

Let's use this thread to tackle (1) and (2). This means we need to

work out if there is rough agreement that the project is a good thing for Django to adopt, particularly focusing on any alternative approaches to the same problem and the relative merits of them, including code design, scalability, alignment with existing Django design and philosophy, and having an available development and maintenance team.

What do folks thing?

Also: I'll be the shepherd for this proposal, but for it to go forward we'd need a larger maintenance team than just me. If there's anyone -- Django committer or not -- who would be willing to commit to long-term maintenance, please ✋ raise your hand here.

[Backstory, and why this is living on my personal github right now. @kennethreitz was looking for a new maintainer, and reached out to me to see if Django might be interested. I thought perhaps so, and offered to take over maintainership in the meantime while we work through the DEP 7 process. If it turns out that an Official Project is the wrong home for this, I'll either maintain it long-term or transfer it again.]

I'm getting this error

It seems to be using the wrong backend. It's using 'django.db.backends.postgresql_psycopg2' with DATABASE_URL='postgres://root:[email protected]:5432/django'.

This is with Django version 3.0

I think this PR addresses a number of outstanding issues, namely:

• The ability to register custom backends/schemas (and simultaneously only support "blessed" Django backends by default)
• The ability to pass arbitrary OPTIONS into config and parse
• Cleaner customization of backend-specific options
• Modernize the testing matrix
• Blacken (and isort) the codebase

As I don't want to impose any more maintenance burden on you, consider this PR also as an offer to maintain this library. My original plan was to simply fork it and release under a new name, but figured it was worth offering. The current test suite is almost entirely unchanged (and passing - https://github.com/imsweb/django-dburl/actions/runs/1373144981) - it only drops pre-2.0 Django support, and registers the previously-supported backends:

https://github.com/imsweb/django-dburl/blob/modernize/test_dj_database_url.py#L12-L23

Happy to discuss further. I have a few projects at work that use this, so I'm invested in keeping it up to date, either by maintaining this library directly or maintaining my own fork under a new name.

I have just realised that the PyPi dj-database-url is pointing to a forked version of this under a different name (https://github.com/kennethreitz/dj-database-url , 0.5.0 from 2018, and no recent activity), but this repo looks like it has more recnt active than that and more up to date with new Django versions.

Are you aware of this?

I am interested in using this. Hense, is there a 'stable/production' version of this available via Pip install?

Will your next release replace the above or be under a different name?

Kind Regards, Hitesh Patel

The database backend "django.db.backends.postgresql_psycopg2" has been deprecated in Django 2.0 in favor of "django.db.backends.postgresql".

https://docs.djangoproject.com/en/2.0/releases/2.0/#id1

Adds support for other special characters in UNIX socket path names, like the colons in Cloud SQL paths.

See also: https://github.com/kennethreitz/dj-database-url/issues/66

This allows the user to specify unix domain sockets as host.

Example: postgresql://%2Fvar%2Flib%2Fpostgresql/dbname

Reference: http://www.postgresql.org/docs/9.2/interactive/libpq-connect.html#AEN38162

Hi, I am getting the following exception when using the connection string.

engine = SCHEMES[url.scheme] if engine is None else engine KeyError: 'postgresql+psycopg2'

Also my connection string starts with postgresql+psycopg2

Can you please suggest me how to fix it? Thanks!

feat:

• MongoDB: using mongdb:// and mongodb+srv:// schemes
• readme.rst: add usage about MongoDB

More information

• djongo document
• pymongo document
• mongodb uri format

Fixes https://github.com/jazzband/dj-database-url/issues/114

Along the way, to make the test cleaner, it fixes all the explicit "set os.environ" calls with mock.patch work instead.

Add support for custom backend registration with optional config post-processing. Add support for passing arbitrary django database settings as kwargs. Add feature description to README and make README more clear. Extract tests with deprecated options to separate suite to simplify further removal.

Shouldn't this function raise a KeyError if s is None?

def config(env=DEFAULT_ENV, default=None, engine=None, conn_max_age=0, ssl_require=False):
    """Returns configured DATABASE dictionary from DATABASE_URL."""

    config = {}

    s = os.environ.get(env, default)

    if s:
        config = parse(s, engine, conn_max_age, ssl_require)

    return config

If the user has not properly configured his environment settings (most likely), and not provided a default fallback value either (also likely), the config will return an empty dictionary, implicitly silencing the issue... (speaking of experience here...) https://devcenter.heroku.com/articles/heroku-postgresql#connecting-in-python

Based on docs: there's no 'sslmode' attribute. The following code gives me the exception: 'sslmode' is an invalid keyword argument. This issue is possibly related to other backends like sqlite as well.

Workaround: On settings.py after: django_heroku.settings(locals()) add: del DATABASES['default']['OPTIONS']['sslmode']
