I was doing research to understand how Odoo 13 works, and I want to add a customized field type like Title, short text, or long text and I want to map them to Odoo 13 as Odoo fields with additional constraints, so the question is:
1- How Odoo 13 store the constraint (func) of a custom model and link them with a specific model?
For me, I want to create a transition layer to create my customized types in the Odoo world.
Thank you all for helping me !
