내 Django 모델 필드와 위젯을 사용하여 내 관리자에게 GoogleMap 위젯을 렌더링하고 있으며, 프로젝트 마이그레이션에서 South를 사용하여 데이터베이스 마이그레이션을 처리하려고합니다. 그러나 많은 노력을 다한 후에 나는 사용자 정의 사우스 규칙을 생성 할 수 없다. 이것은 나의 커스텀 모델이고 내가 시도한 많은 instrospection 규칙 중 마지막이다.Django South가 내 사용자 정의 규칙을 무시합니다.
class GoogleMapMarkerField(models.CharField):
__metaclass__ = models.SubfieldBase
description = _('Un marcador de Google Maps')
widget = GoogleMapMarkerWidget
def __init__(self, center, *args, **kwargs):
kwargs['max_length'] = 100
kwargs['help_text'] = _('Arrastre el cursor en el mapa para seleccionar el punto')
self.center = center
super(GoogleMapMarkerField, self).__init__(*args, **kwargs)
def formfield(self, **kwargs):
defaults = {
'center': self.center,
'form_class':GoogleMapMarkerFormField
}
defaults.update(kwargs)
return super(GoogleMapMarkerField, self).formfield(**defaults)
def to_python(self, value):
if isinstance(value, GoogleMapMarker):
return value
if isinstance(value, list):
return GoogleMapMarker(*map(float, value))
elif isinstance(value, basestring):
try:
return GoogleMapMarker(*map(float, value.split(',')))
except ValueError:
pass
def get_prep_value(self, value):
return '%f,%f' % (value.latitude, value.longitude)
add_introspection_rules([
(
(GoogleMapMarkerField,),
[],
{
'center': ('center', {}),
}
)
], ["^website\.fields\.GoogleMapMarkerField"])
는 그리고 이것은 그것이 위치 인수입니다, 내가
