I want to add translate=True to the company field 

    city = fields.Char(compute='_compute_address', inverse='_inverse_city')

so I inherited the model, altered the field to:

    city = fields.Char(translate=True)

and now it properly shows the country code next to the field:

But unfortunately it ignores all editing when I click on it. Doesn't matter what I write, it's ignored and keeps resetting to Chicago for both languages that I installed

Probably thats connected to the fact that its computed and has an inverse field. Is it still somehow possible to achieve my goal? I want the user to be able to enter the city name in his own language for example the city Köln in german would be Cologne in english. 

I had the same issue for the field:

    company_registry = fields.Char(related='partner_id.company_registry', string="Company ID", readonly=False)

but all I had to do was altering both fields company_registry in res_company and company_registry in res_partner to translate=True and it works now. This approch doesn't seem to work for inverse fields.
