fields from related model not translating

[Paul424]

I found that fields from related models are not translating correctly when referenced via __ notation (don't know how to call it otherwise).

Example:

a.py

class A(models.Model): text = models.CharField(max_length=256) <= field is translated

b.py

class B(models.Model): a = models.ForeignKey('A', related_name='+')

view.py

import b

B.objects.all().values('a__text') <= not translating to current language B.objects.all().values('a__text_nl') <= is actually working!?

import a A.objects.all().values('text') <= correctly translating

+1. Same problem here! I am forced to use the B.objects.all().values('a__text__%s' % lang_code) technique.

Did you solve the problem another way Paul424 ??

I'm doing something similar; retrieve only the specific field(s) based on the language code. Works fine for me. Paul Op 6 mei 2016 20:32 schreef "manikos" [email protected]:

Is there any fix to this that can be done in modeltranslation? There are a few circumstances where using the language specific field is a challenge.

Hello dwasyl, Can you elaborate in what circumstances this workaround is a challenge? Paul

Sure @Paul424, mostly I ran into the issue when using modeltranslation with django-filter. django-filter operates by taking a list of fields and generating a list of possible values to filter the field by, for example if you specify relatedobj__name as a filter field it will get a list of values to generate the filter.

The work around was to subclass the class from django_filter and add a hook to look for specific field names that have translations and change the field name based on get_language(). Took a while to work out the issue and then how to change the third party package to add in the override.

@dwasyl I am currently encountering the same problem using FilterSet. I appreciate your posted solution with subclassing, and I guess some other people may take advantage of your solution.
