Formencode i18n not work with turbogears

[victorlin]

I try to i18n my turbogears2 application. Including error message of formencode. But however, I do set the locale with

        formencode.api.set_stdtranslation(
            domain="FormEncode", languages=["zh_TW"])

in call of BaseController?, but error messages are still english. I find out that formencode use state from turbogears2 to do translation.

And the translation function turbogears2 provided does not work with formencode.

I can't see why turbogears2 provide its own pylons_formencode_gettext rather than use pylons_formencode_gettext of pylons directly.

I try to modify that function tg2 provied, and everything works fine. These are code I modified:

def pylons_formencode_gettext(value):
    from pylons.i18n import ugettext as pylons_gettext
    from gettext import NullTranslations
    from formencode import api

    trans = pylons_gettext(value)

    # Translation failed, try formencode
    if trans == value:
        trans = api._stdtrans(value)

As you see, I just do what pylons do. And everything works fine.

Work around for this problem

Modify config/middleware.py

def make_app(global_conf, full_stack=True, **app_conf):
    import tg.controllers
    import pylons.decorators
    tg.controllers.pylons_formencode_gettext = \
        pylons.decorators.pylons_formencode_gettext

....

#2344 is a duplicate of this however it has the info for the proper fix. We should do like #1999
