Passerelle provides an uniform access to multiple data sources and services.

Quickstart
==========

Setting up an environment (virtualenv)
--------------------------------------

The first thing you'll need is the Python virtualenv package. You probably
already have this, but if not, you can install it with:

    $ easy_install -UZ virtualenv

Once that's done, choose a location for the environment, and create it with the
virtualenv command. For our guide, we're going to choose "venv" in the current
directory:

    $ virtualenv venv
    $ source venv/bin/activate

From Passerelle source directory install required Python packages:

    $ pip install -e .

Initializing the database (quickstart: sqlite3)
-----------------------------------------------

To create the database, execute the following line:

    $ python manage.py migrate

The new database is created inside `passerelle.sqlite3` in the current
directory.

Create a first user with administrative rights:

    $ python manage.py createsuperuser


Running
-------

The command line for starting is:

    $ python manage.py runserver

Passerelle is available on http://127.0.0.1:8000/


Settings
--------

Default settings are loaded from settings.py, they can be overloaded by a
local_settings.py file set in the same directory, or by a file referenced
in the PASSERELLE_SETTINGS_FILE environment variable.


Code Style
----------

black is used to format the code, using thoses parameters:

    black --target-version py37 --skip-string-normalization --line-length 110

isort is used to format the imports, using those parameters:

    isort --profile black --line-length 110

pyupgrade is used to automatically upgrade syntax, using those parameters:

    pyupgrade --keep-percent-format --py37-plus

djhtml is used to automatically indent html files, using those parameters:

    djhtml --tabwidth 2

django-upgrade is used to automatically upgrade Django syntax, using those parameters:

    django-upgrade --target-version 2.2

There is .pre-commit-config.yaml to use pre-commit to automatically run these tools
before commits. (execute `pre-commit install` to install the git hook.)

The .git-blame-ignore-revs file could be used to hide the related
changes into the sources:

    git blame --ignore-revs-file .git-blame-ignore-revs


Tests
-----

Unit tests are written using py.test, and its pytest-django support library and
run using tox.

  tox

To run a specific test under a specific environment.

  tox -e py3-django111 -- -vv tests/test_csv_datasource.py
