16537	layermapping spatial ref check not checking against alternate DB	shifflett.shane@…	jbronn	"django/contrib/gis/utils/layermapping.py uses alternate database to save geometries however when checking the SRID against the SPATIAL REF table it does not check against an alternate database if the user specifies one.  For a user to experience this error they must have two databases and the default database cannot store shape data.  

issue occurs in django/contrib/gis/utils/layermapping.py line 432

OLD CODE (SRID lookup will fail if user has an alternate database storing shape data):
target_srs = SpatialRefSys.objects.get(srid=self.geo_field.srid).srs

PROPOSED FIX (SRID lookup succeeds and functions similar to SAVE function):
target_srs = SpatialRefSys.objects.using(self.using).get(srid=self.geo_field.srid).srs"	Bug	closed	GIS	1.3	Release blocker	fixed			Accepted	1	0	0	0	0	0
