class MakeLine(geo_field)
Availability: PostGIS, SpatiaLite
Returns a LineString
constructed from the point field geometries in the QuerySet
. Currently, ordering the queryset has no effect.
Changed in Django 1.10:
SpatiaLite support was added.
Example:
1 2 3 | >>> qs = City.objects. filter (name__in = ( 'Houston' , 'Dallas' )).aggregate(MakeLine( 'poly' )) >>> print (qs[ 'poly__makeline' ]) LINESTRING ( - 95.3631510000000020 29.7633739999999989 , - 96.8016109999999941 32.7820570000000018 ) |
