From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db.

To do so the idea was something like:

#necessary imports here
def setup_app(command, conf, vars):    
    ....
    for lang in langs:
        set_lang(lang)                      
        content=model.Content()
        content.content=_('content')
        Session.add(content)
    Session.commit()

Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows:

File ".. i18n/translation.py", line 179, in set_lang
    translator = _get_translator(lang, **kwargs)
File ".. i18n/translation.py", line 160, in _get_translator
    localedir = os.path.join(rootdir, 'i18n')
File ".. /posixpath.py", line 67, in join
    elif path == '' or path.endswith('/'):
AttributeError: 'NoneType' object has no attribute 'endswith'

Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object.

Anyone has tried some trick on a similar story ?
