Provides a database structure, API and import scripts to manage French communes, intercommunalités, départements and régions, with their structure and data from Insee and the DGCL.

This app was created as a part of Open Collectivités.

Unaccent extension

If the PostgreSQL user specified in the Django settings is not a superuser, connect to the postgres user and create the Unaccent extension manually:

psql
\c <dbname>
"CREATE EXTENSION  IF NOT EXISTS unaccent;"

Quickstart

1. Add “francedata” to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
       "django_json_widget",
       "simple_history",
       "francedata",
   ]

2. Run python manage.py migrate to create the francedata models.

3. Run the two initialization commands to get the communes, EPCIs, départements and régions structure:

   python manage.py cog_import
   python manage.py banatic_import

4. Visit http://127.0.0.1:8000/admin/ to see the data.
