Hi!
I'm running a simple multilingual site under Mezzanine CMS. Everything was
fine when I was using Mezzanine==3.1.10 and Django==1.6.8. But after
upgrade to Mezzanine==4.0.1 and Django==1.8.3 I get an error when trying to
run ./manage.py with any command.
The error is
./manage.py
update_translation_fields
Traceback (most recent call
last):

i use standard Mezzanine models. My translation.py file is
from modeltranslation.translator import translator, TranslationOptions
from mezzanine.pages.models import Page, RichTextPage, Link
from mezzanine.forms.models import Form, Field
class FormFieldTO(TranslationOptions):
fields = (
'label',
'default',
'placeholder_text',
'choices',
'placeholder_text',
'help_text',
)
class FormTO(TranslationOptions):
fields = (
'response',
'content',
'button_text',
)
class PageTranslationOptions(TranslationOptions):
fields = (
'title',
# 'description',
)
required_languages = (
'ru',
)
class RichPageTranslationOptions(TranslationOptions):
fields = (
'content',
)
required_languages = (
'ru',
)
class LinkTranslationOptions(TranslationOptions):
pass
translator.register(Page, PageTranslationOptions)
translator.register(RichTextPage, RichPageTranslationOptions)
translator.register(Form, FormTO)
translator.register(Link, LinkTranslationOptions)
translator.register(Field, FormFieldTO)
Using a trick from
http://mezzanine.jupo.org/docs/multi-lingual-sites.html#translation-fields-and-migrations
won't help. After switching to USE_MODELTRANSLATION = False and running
python manage.py makemigrations
I get an error:
modeltranslation.translator.NotRegistered: The model "Page" is not
registered for translation
Lines from settings.py related to mulilingual support are:
LANGUAGES = (
('ru', gettext('Russian')),
('en', gettext('English')),
)
USE_MODELTRANSLATION = True
MODELTRANSLATION_DEFAULT_LANGUAGE = 'ru'
...
INSTALLED_APPS = (
# "south",
"modeltranslation",
"django.contrib.admin",
"django.contrib.auth",
"django.contrib.contenttypes",
"django.contrib.redirects",
"django.contrib.sessions",

)
Thanks in advance for any help!
