Как использовать django-modeltranslation за пределами админки?

Павел Аксенов, Со следующими настройками в БД создались поля title, title_en, title_de, body, body_en, body_de. Пытаюсь вывести поля в форму, но выдает странную ошибку. Как вы думаете, как можно исправить данную проблему?

settings.py:

LANGUAGE_CODE = 'ru'

LANGUAGES = (
    ('ru', _('Russian')),
    ('en', _('English')),
    ('de', _('German')),
)

MODELTRANSLATION_LANGUAGES = ('en', 'de')

forms.py:

from modeltranslation.forms import TranslationModelForm

class ArticleForm(TranslationModelForm):
    """
        Form based on "Article" model.
    """

    class Meta:
        model = Article
        fields = ('title', 'title_en', 'title_de', 'body', 'body_en', 'body_de',)

    def __init__(self, *args, **kwargs):
        super(ArticleForm, self).__init__(*args, **kwargs)
        self.fields['title'].widget.attrs = {
            'class': 'form-control',
            'id': 'title',
        }
        self.fields['title_en'].widget.attrs = {
            'class': 'form-control',
            'id': 'title_en',
        }
        self.fields['title_de'].widget.attrs = {
            'class': 'form-control',
            'id': 'title_de',
        }
        self.fields['body'].widget.attrs = {
            'class': 'form-control',
            'id': 'opt_head',
        }
        self.fields['body_en'].widget.attrs = {
            'class': 'form-control',
            'id': 'body_en',
        }
        self.fields['body_de'].widget.attrs = {
            'class': 'form-control',
            'id': 'body_de',
        }
