Description
On MySQL, a raw float value is returned, as it’s not possible to automatically determine the unit of the field.
but
In [3]: City.objects.annotate(d=Distance('point', Point(0, 0, srid=4326))).first().d Out[3]: Distance(m=1.41421356237)
I see two ways how to fix it:
- made Distance function to return raw values on MySQL
- raise NotImplemented if Distance function is applied to geodetic field
