Model translation for Django without magic-inflicted pain

Django model translation without magic-inflicted pain.

Installation and usage

After installing django-translated-fields into your Python environment all you have to do is define LANGUAGES and adding translated fields to your models:

from django.db import models
from django.utils.translation import gettext_lazy as _

from translated_fields import TranslatedField


class Question(models.Model):
    question = TranslatedField(
        models.CharField(_('question'), max_length=200),
    )
    answer1 = TranslatedField(
        models.CharField(_('answer 1'), max_length=200),
    )
    answer2 = TranslatedField(
        models.CharField(_('answer 2'), max_length=200),
    )
    answer3 = TranslatedField(
        models.CharField(_('answer 3'), max_length=200, blank=True),
    )

    def __str__(self):
        return self.question

Model fields are automatically created from the field passed to TranslatedField, one field per language. The TranslatedField instance itself is replaced with a property which returns the current language’s attribute. There are no default values or fallbacks, only a wrapped attribute access.

If model field creation is not desired, you may also use the translated_attributes class decorator. This only creates the attribute getter property:

from translated_fields import translated_attributes

@translated_attributes('attribute', 'anything', ...)
class Test(object):
    attribute_en = 'some value'
    attribute_de = 'some other value'

There is no support for automatically referencing the current language’s field in queries or automatically adding fields to admin fieldsets and whatnot. The code required for these features isn’t too hard to write, but it is hard to maintain down the road which contradicts my goal of writing low maintenance software. Still, feedback and pull requests are very welcome! Please run the style checks and test suite locally before submitting a pull request though – all that this requires is running tox.
