Direct access to ir_config_parameter on field definition

Question

Hello everyone,
In Odoo 12 we can directly access company model data on field definition like for instance:
my_field = fields.Char('Test field', default=lambda self: self.env.user.company_id.my_field) This way we have access to desired values set on company model.
What about if I want to directly access values on "*ir_config_parameters*" (not on the res_company model) from field definition?
Something like:
my_field = fields.Char(default=lambda self: direct_access_to_ir_config_parameters_here)

Hello paulo,
you can do like:

def get_my_field_value(self):
config = self.env['ir.config_parameter']
return config.sudo().get_param("key_to_fetch_value")
my_field = fields.Char('Test field', default=get_my_field_value)

Hello Paulo,

Also update the functions get_values() and set_values() according to this field.
