【问题描述】：
我正在尝试根据其他字段的多个onchange 函数（例如brand_id 和origin_id）动态更改many2many 字段products_ids 的值。
到目前为止，一切都很好，它确实显示了预期值，但是一旦我点击保存按钮，many2many 字段的值就会消失
class CustomModifyPrice(models.Model):
brand_id = fields.Many2many(comodel_name="custom.brand", string="Brand", required=False, )
origin_id = fields.Many2many(comodel_name="custom.country", string="Origin", required=False, )
product_ids = fields.Many2many(comodel_name="custom.product", string="Products", readonly=True, )
search_terms = {}
product_ids_list = []
@api.onchange('brand_id')
def onchange_change_brand(self):
for rec in self:
product_brands = []
for prod_brand in rec.brand_id:
product_brands.append(prod_brand.id)
rec.search_terms["product_brands"] = product_brands
rec.get_products()
@api.onchange('origin_id')
def onchange_change_origin(self):
for rec in self:
product_origins = []
for prod_origin in rec.origin_id:
product_origins.append(prod_origin.id)
rec.search_terms["product_origins"] = product_origins
rec.get_products()
def get_products(self):
domain = []
self.product_ids_list = []
if 'product_brands' in self.search_terms:
product_brands = self.search_terms['product_brands']
if product_brands:
tuple1 = ('brand_id', 'in', product_brands)
domain.append(tuple1)
if 'product_origins' in self.search_terms:
product_origins = self.search_terms['product_origins']
if product_origins:
tuple1 = ('country_id', 'in', product_origins)
domain.append(tuple1)
if domain:
products = self.env['custom.product'].search(domain)
if products.ids:
for prod in products:
self.product_ids_list.append(prod.id)
self.product_ids = [(6, False, self.product_ids_list)]
【问题讨论】：
-
你的字段是只读的，尝试使用force_save
-
我完全同意 Kenly。在您的 xml 视图中使用 force_save=1。
