Hello,
I'm working a Flask APP and use Flask Tryton to connect to Tryton (1)
I have blueprints and context processor to connect to Tryton
* Blueprint (2). Modular Application
* Context Processor: Functions in templates
I have some routes or views call Tryton with @tryton.transaction
Also I have in some context processor call Trytn with @tryton.transaction.
My problem is about I can't start two or more transaction. Second
transaction, self.user is not None and get assert error (4)
I don't find solution to use Blueprint and Context Processor working
together. Any ideas?
Example:
*app.py*
from flask import app
from flask_tryton import Tryton
...
@app.context_processor
def cms_processor():
tryton = Tryton(app)
@tryton.transaction()
def menu(code):
print "Call tryton model"
return []
return dict(cms_menu=menu)
*blueprint.py*
from flask import Blueprint, current_app
from flask_tryton import Tryton
cms = Blueprint('cms', __name__, template_folder='templates')
@cms.route("/<slug>", endpoint="article")
def article(lang, slug):
tryton = Tryton(current_app)
@tryton.transaction()
def _get_article(slug):
print "Call tryton model"
return _get_article(slug)
