我怎麼能一次選擇一個領域的其他領域有價值？

Question

我要的是有一次我選擇的第一個字段與此相關的選擇等領域有自己的價值觀

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

nameTest是一個對象，我怎麼能訪問該領域相關到這個對象？

Answer 1

你有2個選擇這裏（我已經改變了nameTest在我的例子my_many2one_id！）：

1. 使用的onchange行爲

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 

使用相關領域

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") 

Answer 2

使用

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

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

Answer 3

你需要的是相關領域：

讓利說有model.one

_name = 'model.one' 

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

和模型model.two有one2many場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) 

當您選擇many2one字段 時，會自動更改相關字段的工作，如代理或計算字段。

，如果你只是想填補該領域與相關領域的價值創造 onchange事件

@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
