how can I once I select a field the other fields have values?

What I want is once I choose the first field the fields related to this choice have their values

enter image description here

    nameTest = fields.Many2one(
        comodel_name='medical.lab.patient',
        required=True,
    )

nameTest is an object how can I access the fields related to this object?

what you need is related field :

let say there is model.one

 _name = 'model.one'

 field_1 = fields.Char(..)
 field_2 = fields.Date(..)

and model model.two that have one2many field to model.one

_name = 'model.two'

 many2one_field = fields.Many2one(co_model='model.one', ....)
 # just add related field two use them in the view.
 # here I chosed to give them the same name 
 # if you don't specify any attribute like string , required ....
 # they inherit the attributes of the model.one fields
 field_1 = fields.Char(related='many2one_field.field_1',
                        readonly=True)
 field_2 = fields.Date(related='many2one_field.field_2',
                        readonly=True)

related field work like a proxy or a compute field when you select the many2one field there value is automatically changed.

and if you just want to fill the field with the value of the related field create onchange event

   @api.onchange('many2one_field')
   def onchange_many2OneField(self):
        # first check many2one field have value
        if self.many2one_field:
            self.field_1 = self.many2one_field.some_field_1
            self.field_2 = self.many2one_field.some_field_2
        else:
            # make them all False if it what you want
            self.field_1 = False
            self.field_2 = False

You have 2 options here (i've changed nameTest to my_many2one_id in my examples!):

  1. use onchange behaviour
class MyModel(models.Model):
    _name = 'my.model'

    my_many2one_id = fields.Many2one(
        comodel_name='medical.lab.patient',
        required=True
    )
    my_field1 = fields.Boolean(string="My Field1")
    my_field2 = fields.Char(string="My Field2")

    @api.onchange('my_many2one_id')
    def onchange_my_many2one_id(self):
        self.my_field1 = self.my_many2one_id.my_field1
        self.my_field2 = self.my_many2one_id.my_field2
  1. use related fields
    my_field3 = fields.Boolean(
        string="My Field3", related="my_many2one_id.my_other_field3")
    my_field4 = fields.Char(
        string="My Field4", related="my_many2one_id.my_other_field4")

Use 

@api.onchange(put_your_fields_here)
def onchange_custom(self):

return {'value': {'field_1': value1, 'field_2': value_2)}
