Error adding translation for Injected Fields

[bookhankaa]

Following for this section of manual Translation for Injected Fields I'm trying to add translated extrafield for RichTextPage model:
settings.py

EXTRA_MODEL_FIELDS = (
    (
        "mezzanine.pages.models.RichTextPage.quote",
        "TextField",
        ("Page's Quote",),
        {"blank": True},
    ),
)

translation.py

from modeltranslation.translator import translator
from mezzanine.pages.translation import TranslatedRichTextPage
from mezzanine.pages.models import RichTextPage

class TranslatedInjectedPage(TranslatedRichTextPage):
    fields = ('quote',),

translator.unregister(RichTextPage)
translator.register(RichTextPage, TranslatedInjectedPage)

and I get:

Error adding translation field. Model 'RichTextPage' already contains a field named 'content_en'.

[bookhankaa]

from modeltranslation.translator import translator, TranslationOptions
from mezzanine.pages.models import RichTextPage

class TranslatedInjectedPage(TranslationOptions):
    fields = ('quote',),

translator.unregister(RichTextPage)
translator.register(RichTextPage, TranslatedInjectedPage)

All fields and quote field transleted, content field NOT transleted.

And just simple:

from modeltranslation.translator import translator
from mezzanine.pages.translation import TranslatedRichTextPage
from mezzanine.pages.models import RichTextPage

translator.unregister(RichTextPage)
translator.register(RichTextPage, TranslatedRichTextPage)

Doesn't works with error:
Model 'RichTextPage' already contains a field named 'content_en'.

This is a bug of django-modeltranslation that never got addressed.

One workaround would be to manually add translated fields using EXTRA_MODEL_FIELDS for each target language.
