Depending on your model, you can do this switch statement inside a
model method.
Something like this :
==============================================
from django.db import models
from django.conf import settings
class Post(models.Model):
title_en = ...
title_sv = ...
def title(self):
if settings.LANGUAGE_CODE == 'en':
return self.title_en
else:
return self.title_sv
==============================================
... and so, your only need to specify "{{ post.title }}" in your
template.
However, it can be a bit verbose if you have several fields with the
same scheme as "title_*".
Or maybe, if you like dark magic art, you can try to set up a
__getattr__ method in your Post class, like that :
=============================
def __getattr__(self, attribute):
lang = settings.LANGUAGE_CODE
return getattr(self, "%s_%s" % (attribute, lang))
=============================
It seems to work :
>>> from django.conf import settings
>>> p = m.Post.objects.all()[0]
>>> settings.LANGUAGE_CODE
'en'
>>> p.title
u'en title'
>>> settings.LANGUAGE_CODE = 'sv'
>>> p.title
u'sv title'
>>> settings.LANGUAGE_CODE = 'en'
>>> p.title
u'en title'
... but you might want to refine this, because it's a bit hacky and it
explodes if you specify an non-existing attribute (recursives calls, and
the like).
Or, if you are not-so-evil, you can try to make a template filter,
which takes in parameters a field, and it will try to do this (instead
of the tricky use of getattr in the Model class).
Something like :
==================================
from django.conf import settings
from django.template.defaultfilters import stringfilter
from django import template
register = template.Library()
@register.filter
@stringfilter
def translate(obj, field):
return getattr(obj, "%s_%s" % (field, settings.LANGUAGE_CODE))
==================================
And you should be able to use it like that in your templates :
{{ post|translate:"title" }}
But it's not very pretty neither.
The first proposition is the cleaner, but it's not really dry.
The second one can be great, but you can shoot yourself in the foot
with __getattr__. Be careful.
I hope it might help (or give ideas ...)
