I've installed a module that should works with translations defined in the odoo 8. But when i checked the path, there is no defined directories. 

class WebClient(openerpweb.Controller):

    @http.route('/web/webclient/translations', type='json', auth="none")

    def translations(self, mods=None, lang=None):

In the /web/ directory only i18n directory exists and only contains .po files. because i'm new in odoo i think it is not correct in the module. so how i could change this request and fix the problem?
