Thanks, Niyas.

My problem is not the line of code but the Dependencies - I must a dependent field here:

My compute field is in the model res.partner and it must be computed based on the model x_contrat.
But I'm not able to refer on the model x_contrat.
Is there any way to it ?

Hi,

If you are looking to get some data from the model x_contract, you have to modify your code as follows:

domain = [('id', '=, 10)]
self.env['x_contrat'].search(domain, limit=1).x_studio_contacts_1

in the above sample code, i have used search method to access data from the x_contrat model, in the domain you have to pass your search criteria based on the relation ship between your models. Please change the hard coded domain from the above example as per your use case.

Thanks
