class vectorformats.Formats.Django.Django(*args, **kwargs)

This class is designed to decode a Django QuerySet object into Feature.Vector objects.

Simply pass a query_set to the decode method, and it will return a list of Features.

Example Usage:

>>> from vectorformats.Formats import Django, GeoJSON
>>> qs = Model.objects.filter(city="Cambridge")
>>> djf = Django.Django(geodjango="geometry", properties=['city', 'state'])
>>> geoj = GeoJSON.GeoJSON()
>>> string = geoj.encode(djf.decode(qs))
>>> print string 

geodjango

If you have GeoDjango geometry columns, set this to the name of the geometry column.

pickled_geometry

If you are not using GeoDjango, but have instead stored your geometry as pickled GeoJSON geometries in a column in GeoDjango, set the pickled_geometry=True option in your class constructor.

pickled_properties

A column in the database representing a pickled set of attributes. This will be used in addition to any properties in the ‘properties’ list, with the list as a preference.

properties

List of properties you want copied from the model to the output object.
