Not working with Flask-Babel?

[vincentwhales]

I am using two extensions:

Flask-User (which uses Flask-Babel), and
Flask-Admin (which uses Flask-Babelex)

When I try to get i18n working for my application, I am seeing cryptic errors such as:

Traceback (most recent call last):

Is there a guide to integrating both extensions at the same time?

Good question. Does anyone happen to know what is the overall situation of Flask-Babel vs Flask-BabelEx? Planning upgrade Flask app to all latest. Using Flask-Babel now, but seems like some Flask libraries qill require BabelEx (and as pointed above those are not compatible), plus force_locale missing from BabelEx. OTOH, BabelEx is not being actively developed (last commit almost a year ago), or is it?. I was even thinking to make some kind of BabelEx with force_locale, but not quite sure whether there is any perspective.

PS. You can probably get away by importing gettext from Flask-BabelEx instead of Flask-Babel, but I unfortunately can't.
