imago

This is the django app that powers api.opencivicdata.org

Python 3.3 or newer required, Python 2 compatibility is not guaranteed.

Getting Started

• Install Represent Boundaries.
• Add 'imago' to your INSTALLED_APPS.
• Add ('', include('imago.urls')), to urls.py.

Imago's loadmappings management command loads mappings between divisions managed by opencivicdata-django and boundaries managed by Represent Boundaries. If mappings are not loaded, then the lat and lon filters on the /people/ and /divisions/ endpoints will not work, and geometries will not appear on the /divisions/ endpoint. For the command to succeed, you must set the IMAGO_COUNTRY and IMAGO_BOUNDARY_MAPPINGS settings:

• Set IMAGO_COUNTRY to a two-letter, lowercase country code like 'us' in settings.py, to select which country's Open Civic Data Division Identifiers to use.
• Set IMAGO_BOUNDARY_MAPPINGS in settings.py, a dictionary in which each key is the slug of a boundary set and each value is a dictionary, which has as keys:
  • key: The property of a division identifier that will be used for matching.
  • boundary_key: Optional. Defaults to external_id. The property of a boundary that will be used for matching, or a lambda that takes a boundary as an argument and returns a string that will be used for matching.
  • prefix: Imago will prepend this prefix to the property of the boundary, identified by boundary_key, and will look for the division identifier whose property, identified by key, matches.
  • ignore: Optional. A regular expression string. If no match is found, and if either ignore is missing or the boundary name doesn't match the regular expression, a warning will be issued about the unmatched boundary.

See api.opencivicdata.org's settings.py for an example.
