Question

我是odoo dev中的新手，我正试图让'formula'字段发生变化（在marketplace.marketplace模型中）时字段值'recommanded_price'（来自marketplace.marketplaceinfo模型）改变

我使用了@ api.depends装饰器，但它没有触发函数

这是我的代码的基本要素

class marketplace(models.Model):
_name = 'marketplace.marketplace'
_description = 'Marketplace'

formula = fields.Char('Formula')
product_ids = fields.One2many('marketplace.marketplaceinfo', 'mkp', 'Products')

class marketplace_info(models.Model):
_name = 'marketplace.marketplaceinfo'
_description = 'Information about a product marketplace'
mkp = fields.Many2one('marketplace.marketplace','Marketplace',ondelete = 'cascade',required = True,
help='Marketplace of this product'
)
product_tmpl_id = fields.Many2one(
'product.template', 'Product Template',
index=True, ondelete='cascade')
price = fields.Float('Price', default=0.0, digits=dp.get_precision('Product Price'),
help="The selling price for a product within the marketplace")
recommonded_price = fields.Float('Recommended Price', compute='_compute_recommonded_price' ,default=0.0, digits=dp.get_precision('Product Price'),
readonly = True, help="The recommended selling price for a product within the marketplace")

@api.depends('mkp.formula')
def _compute_recommonded_price(self):
#do something

Answer 1

@ api.depends

如果装饰器中指定的任何字段被ORM更改或在表单中更改，则此装饰器将触发对装饰函数的调用：

@api.depends('name', 'an_other_field')
def afun(self):
pass

其他你可以使用另一个装饰

@ api.onchange

如果装饰器中指定的任何字段在表单中更改，则此装饰器将触发对装饰函数的调用：

@api.onchange('fieldx')
def do_stuff(self):
   if self.fieldx == x:
       self.fieldy = 'toto'

差异：在上一个示例中，self对应于当前在表单上编辑的记录。在on_change上下文中，所有工作都在缓存中完成。因此，您可以在函数内部更改RecordSet，而无需担心更改数据库。这是@ api.depends

的主要区别
