我怎么能一次选择一个领域的其他领域有价值？

Question

我要的是有一次我选择的第一个字段与此相关的选择等领域有自己的价值观

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

nameTest是一个对象，我怎么能访问该领域相关到这个对象？

Answer 1

你有2个选择这里（我已经改变了nameTest在我的例子my_many2one_id！）：

1. 使用的onchange行为

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. 使用相关领域

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") 

开始=>

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

你需要的是相关领域：

让利说有model.one

_name = 'model.one' 

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

和模型model.two有one2many场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) 

当您选择many2one字段 时，会自动更改相关字段的工作，如代理或计算字段。

，如果你只是想填补该领域与相关领域的价值创造 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
