Hi, I am working in a flask app that pass some arguments to tryton. I imported Transaction in flask routes file. Something like described here: from trytond.transaction import Transaction @bp.route('/course/',methods=['GET', 'POST']) @tryton.transaction(readonly=False,user=1) def course(): …

In you case you could just do: … with Transaction().set_context(courses=courses): defaults['lessons'] = Lesson.browse(lessons) …

[image] iehoshia: Do I need to use @tryton.transaction() or something similar? Flask tryton accepts an optional context parameter . It can be set with a dict (or a method that returns a dict). This values will be set on the transaction context .

I don’t know how to use it correctly to pass context with @tryton.transaction() because it is used like a decorator before define the function with the route. How it is used inside the function and update the context?

[image] iehoshia: from trytond.transaction import Transaction @bp.route('/course/',methods=['GET', 'POST']) @tryton.transaction(readonly=False,user=1) def course(): with Transaction().set_context(courses=courses): # do something Maybe you should get “courses” before to pass…

[image] maxx: with I can get courses variable inside, but not to pass it, it does not work. [image] maxx: with Transaction().set_context(courses=data[‘courses’]): Maybe create an aditional @bp.route with the decorator and the context param. I’m not sure if it is the best way.

I tried it too, but doesn’t work neither…

What does not work? Which error do you have? What are you trying to achieve? If you don’t give more details it’s not possible to help you.

Hi, I have the follow route in flask. Every lesson has a course, and need to pass it to tryton. #from trytond.transaction import Transaction #doesn't workd from flask_tryton import Transaction #doesn't work neither @bp.errorhandler(404) @bp.route('/<base>/<slug>/',methods=['GET', 'POST']) @tryton…

An Model instance keep a copy of the context that was used when it was instantiate. So if you want to change the context of an instance, you must re-instantiate below the new context.

So, I need to create a new route in flask? Or how to re-instantiate the context?

Pass context from flask to tryton

Why don’t you use:

from flask_tryton import Tryton, Transaction
