yet
been defined

------------------------------------------+---------------------------------
If I specify 'order_with_respect_to' on a field linked to a model that
hasn't been defined yet, I get the following error:
<...>File "/usr/lib/python2.6/dist-packages/django/db/models/base.py",
line 223, in _prepare
setattr(opts.order_with_respect_to.rel.to, 'get_%s_order' %
cls.__name__.lower(), curry(method_get_order, cls))
AttributeError: 'str' object has no attribute 'get_location_order'
When I swap declarations of Location and City models, the error
disappears.
Here is the code:
class Location(TimeStampedModel):
'''Single location on a map, e.g. building.'''
address = models.CharField(u"адрес", max_length=75, help_text=u"Улица,
корпус, дом")
city = models.ForeignKey('City', related_name="locations",
verbose_name=u"город")
metro_stations = models.ManyToManyField('MetroStation',
related_name="locations", verbose_name=u"ближайшие станции метро",
blank=True, null=True)
class Meta:
verbose_name = u"адрес"
verbose_name_plural = u"адреса"
order_with_respect_to = 'city'
class City(TimeStampedModel):
'''A city.'''
name = models.CharField(u"название", max_length=30)
class Meta:
verbose_name = u"город"
verbose_name_plural = u"города"
