Hello,

I'm new on Odoo, after researches on diferent website/forum, I didn't find an answer to my question.

The Git to see files: https://github.com/AdrienPr/Odoo-Tutorial-Building-a-Website

I'm following this tutorial at the "Selling Courses" part: https://www.odoo.com/documentation/14.0/developer/howtos/website.html#selling-courses

From the ERP side we can see a list of Teachers and when we clic on a teacher we can see all the list of courses that the teachers have.

Courses have to be added from the ERP and are not for sall.

The next step is to have the possibility to sell Course0, Course1 and Course2 present in demo.xml by adding them to the existing products in Product.template.

The issue is that even by folling the Odoo tutorial and others. I didn't find a solution to display new courses present in demo.txt in the Shop

Find bellow all codes hope someone will find a solution to finish this tutorial.

Best regards

Adrien
