try this
In Second Model, write this
@api.onchange('name')
def get_date_from_first_model_using_name(self):
Obj= self.env['res.partner'].search([('name', '=', self.name)])
get_date= Obj[0].Date_naissance
self.second_model_column_name= get_date
# This will get date from first model using name field
# Please Tick this answer if this help you
