And what do you want to do with it? 

I have similar cases where I have a setting in res.config.settings with a get_values and set_values in the module and then accessed with get_param from other modules... (I mean to access a global setting from other modules)

I'm sorry but I had to rewrite my question to better explain the case. This is an example of what I am talking about:


from odoo import models, fields

class ResConfigSettings(models.TransientModel):
    _inherit = 'res.config.settings'

    custom_setting = fields.Boolean(
        string="Custom Setting",
        related="company_id.custom_setting",
        readonly=False
    )

class ResCompany(models.Model):
    _inherit = 'res.company'

    custom_setting = fields.Char(string="Custom Setting")
