Hi,
I am having a bit of a problem. I have a model with 3 name fields,
each for a different language. By creating an __unicode__ function
like below, I always get the correct name for the current language.
Works fine.
But, I want to change the default ordering for this model, so that in
each language, the correct order is used. Sadly, this doesn't work, as
I get the error "NameError: name 'Substrate' is not defined". Also
"self" and "super" don't seem to work. I just can't seem to be able to
access the parent class from within the Meta class.
I can't even repeat the getLanguage function into the Meta class,
because then I get an the error "TypeError: 'class Meta' got invalid
attribute(s): getLanguage".
class Substrate(models.Model):
name_en = models.CharField(max_length=255)
name_de = models.CharField(max_length=255, blank=True)
name_nl = models.CharField(max_length=255, blank=True)
def getLanguage(self):
from django.utils import translation
current_language = translation.get_language()
if not current_language:
current_language = 'en'
return current_language
def getName(self):
current_language = self.getLanguage()
name = getattr(self, 'name_'+current_language, self.name_en)
if not name:
name = self.name_en
return name
def __unicode__(self):
return self.getName()
class Meta:
ordering = [('name_%s' % Substrate.getLanguage()), 'name_en']
If anyone has an idea how on to do this, I would be very happy.
Thanks!
Cheers,
Kevin
