There was a little mistake in the initial design of flask-tryton. It should be fixed with https://code.google.com/p/flask-tryton/source/detail?r=34c8b01ac62f6ad2431c90088f32a87f8e6df7af Otherwise, you should not use current_app but import the instance of Flask from the right module. > *app.py* > > from tryton import tryton > > @app.context_processor > def cms_processor(): > > def menu(code=None): > Menu = tryton.pool.get('cms.menu') Should be (with latest code): tryton = current_app.extensions['Tryton'] Menu = tryton.pool.get('cms.menu') > print "call search tryton > > return dict(cms_menu=menu) > > *tryton.py* > > from flask import current_app > from flask_tryton import Tryton > > tryton = Tryton() > > *blueprint.py* > > from flask import Blueprint, current_app > from galatea.tryton import tryton > > cms = Blueprint('cms', __name__, template_folder='templates') > > @cms.route("/<slug>", endpoint="article") > @tryton.transaction() > def article(lang, slug): > Article = tryton.pool.get('cms.article') init_app should be called to use the pool. > print "call search tryton model" -- Cédric Krier - B2CK SPRL Email/Jabber: cedric.kr...@b2ck.com Tel: +32 472 54 46 59 Website: http://www.b2ck.com/
