Comment (by copelco):
To illustrate volrath's suggested changes, the provided patch would allow
you to do something along the lines of this:
{{{#!python
from django import forms
from django.contrib.gis.forms import GeometryField
class CoordsWidget(forms.MultiWidget):
def __init__(self, *args, **kwargs):
widgets = (forms.TextInput(), forms.TextInput())
super(CoordsWidget, self).__init__(widgets, *args, **kwargs)
def decompress(self, value):
return value.coords
class CoordsField(GeometryField):
widget = CoordsWidget
def to_python(self, value):
wkt = "POINT({0} {1})".format(value[0], value[1])
return super(CoordsField, self).to_python(wkt)
class LocationForm(forms.ModelForm):
point = CoordsField()
class Meta(object):
model = Location
}}}
