General Transit Feed Specification (GTFS) as a Django app
multigtfs: GTFS as a Django app
multigtfs is an Apache 2.0-licensed Django app that supports importing and exporting of GTFS feeds. All features of the June 20, 2012 reference are supported. It allows multiple feeds to be stored in the database at once.
It requires a spatial databases compatible with GeoDjango. PostgreSQL 9.x and PostGIS 2.x are recommended for development and production, since these support all the GeoDjango features. There are issues with GeoDjango in Django 1.4 (see #20036), so Django 1.5 or above is recommended.
- pip install multigtfs
- In your settings, add multigtfs to your INSTALLED APPS and ensure you have a spatial database configured.
- ./manage.py syncdb to install the tables, or ./manage.py migrate if you are using South
There are two management commands to get GTFS feeds in and out of the database:
./manage.py importgtfs [--name name_of_feed] path/to/gtfsfeed.zip ./manage.py exportgtfs [--name basename_of_file] <feed_id>
multigtfs is composed of Django models that implement GTFS, plus helper methods for importing and exporting to the GTFS format. Where GTFS relates objects through IDs (such as Stop IDs for stops), multigtfs uses ForeignKeys.
multigtfs includes a Feed object, which is not part of GTFS. This is used to include several feeds in the same file without collisions. These can be feeds from different agencies, or different versions of a feed from the same agency. The object has a helper method, in_feed, that is sometimes useful in filtering objects by feed. At other times, it is easier to start at the feed and follow relations.
There isn’t separate documentation yet. Load the app in your Django project, play with the admin, and read the source code to learn more.
multigtfs was first developed for the Tulsa Web Devs’ project to get Tulsa’s buses into Google Maps. tulsa-transit-google is the Tulsa-specific portion, and multigtfs contains the parts useful for any GTFS effort. Tulsa’s bus schedule appeared on Google Maps in July 2013, after a two-year effort. The Tulsa Web Devs founded Code for Tulsa to collaborate on future civic tech projects.
Upcoming features include:
- A sample project
- Validating the feed against Google’s requirements
- More documentation
- More flexible GTFS imports and exports (longer values, extra columns)
See the issues list for more details.
This release was sponsored by MRCagney.
- Convert to GeoDjango: Stops and ShapePoints use Points rather than lat/long, admin shows map of points, and new configuration settings to customize.
- Import south in try/except blocks (so that South really is optional).
- Django 1.5 or above is now required.
- Remove verify_exists from URLField, so it can be used in Django 1.5
- Human-friendly sorting for rest of GTFS output
- Added optional manual sorting of output, used on stop_times.txt
- Added South migrations for applying 0.2.2 changes
- Fixed Fare.transfers for unlimited rides (use None instead of -1)
- First PyPi version
