Description:

djangoenviron 0.11.2

django-environ is the Python package that allows you to use
Twelve-factor methodology to configure your
Django application with environment variables.
For that, it gives you an easy way to configure Django application using
environment variables obtained from an environment file and provided by the OS:
import environ
import os

env = environ.Env(
# set casting, default value
DEBUG=(bool, False)
)

# Set the project base directory
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

# Take environment variables from .env file
environ.Env.read_env(os.path.join(BASE_DIR, '.env'))

# False if not in os.environ because of casting above
DEBUG = env('DEBUG')

# Raises Django's ImproperlyConfigured
# exception if SECRET_KEY not in os.environ
SECRET_KEY = env('SECRET_KEY')

# Parse database connection url strings
# like psql://user:pass@127.0.0.1:8458/db
DATABASES = {
# read os.environ['DATABASE_URL'] and raises
# ImproperlyConfigured exception if not found
#
# The db() method is an alias for db_url().
'default': env.db(),

# read os.environ['SQLITE_URL']
'extra': env.db_url(
'SQLITE_URL',
default='sqlite:////tmp/my-tmp-sqlite.db'
)
}

CACHES = {
# Read os.environ['CACHE_URL'] and raises
# ImproperlyConfigured exception if not found.
#
# The cache() method is an alias for cache_url().
'default': env.cache(),

# read os.environ['REDIS_URL']
'redis': env.cache_url('REDIS_URL')
}
The idea of this package is to unify a lot of packages that make the same stuff:
Take a string from os.environ, parse and cast it to some of useful python
typed variables. To do that and to use the 12factor
approach, some connection strings are expressed as url, so this package can parse
it and return a urllib.parse.ParseResult. These strings from os.environ
are loaded from a .env file and filled in os.environ with setdefault
method, to avoid to overwrite the real environ.
A similar approach is used in Two Scoops of Django
book and explained in 12factor-django
article.
Using django-environ you can stop to make a lot of unversioned
settings_*.py to configure your app.
See cookiecutter-django
for a concrete example on using with a django project.

Contributing
If you would like to contribute to django-environ, please take a look at the
current issues. If there is
a bug or feature that you want but it isn’t listed, make an issue and work on it.

Bug reports
Before raising an issue, please ensure that you are using the latest version
of django-environ.
Please provide the following information with your issue to enable us to
respond as quickly as possible.

The relevant versions of the packages you are using.
The steps to recreate your issue.
The full stacktrace if there is an exception.
An executable code example where possible

Guidelines for bug reports:

Use the GitHub issue search — check if the issue has already been
reported.
Check if the issue has been fixed — try to reproduce it using the latest
main or develop branch in the repository.
Isolate the problem — create a reduced test case and a live example.

A good bug report shouldn’t leave others needing to chase you up for more
information. Please try to be as detailed as possible in your report. What is
your environment? What steps will reproduce the issue? What OS experience the
problem? What would you expect to be the outcome? All these details will help
people to fix any potential bugs.


Feature requests
Feature requests are welcome. But take a moment to find out whether your idea
fits with the scope and aims of the project. It’s up to you to make a strong
case to convince the project’s developers of the merits of this feature. Please
provide as much detail and context as possible.


Pull requests
Good pull requests - patches, improvements, new features - are a fantastic
help. They should remain focused in scope and avoid containing unrelated
commits.
Follow this process if you’d like your work considered for inclusion in the
project:

Check for open issues or open a fresh issue to start a discussion around a
feature idea or a bug.
Fork the repository
on GitHub to start making your changes to the develop branch
(or branch off of it).
Write a test which shows that the bug was fixed or that the feature works as
expected.
Send a pull request and bug the maintainer until it gets merged and published.

If you are intending to implement a fairly large feature we’d appreciate if you
open an issue with GitHub detailing your use case and intended solution to
discuss how it might impact other work that is in flight.
We also appreciate it if you take the time to update and write tests for any
changes you submit.
By submitting a patch, you agree to allow the project owner to license your
work under the same license as that used by the project.
