Delegation inheritance in tryton

[Manuel Alejandro Márquez Ortiz]

Hello, I'm new in tryton and I come from Odoo. I am developing a new module and I need inherit from model product.template but I dont want extend the table product_template in the database, I want that tryton creates a new table for my model and still inherit features and fields from the model product.template. This in Odoo is done with the inherits attribute in the class of model. Is that posible in Tryton ?

It has been removed since 2.8

There was many issues with this "feature" like the access rights,
default values, order resolution of _inherits, modularity against super
calls etc. But also it was quite difficult to understand for the user
(explicit is better then implicit).

There are three options.

Do you really need to have a new model? Could it not be stored in
product.template?

You can simply use a Many2One on your new model and so have an explicit
link. This is the solution the most often used in Tryton like Carrier,
Bank, Agent, etc.

Or you can do like for Product use an explicit Many2One but create
Function field which shows the value of the template.

Thanks for the quick answer, I will try the last option, as is done in
product module.
