Question

我有一个模型“ custom.products”，它通过一个one2many字段“ branch_line”连接到模型“ custom.branch.line”，我想在相关字段“ branch1”和“ branch2”上应用域过滤器，我希望它显示每个分支中每种产品的数量，但是当我将domain应用于相关字段时，它不起作用，它只是检索数据库表中的第一个条目，我的代码在下面

class CustomProduct(models.Model):
    _name = 'custom.product'
    _description = 'Product Record'

    branch_line = fields.One2many('custom.branch.line', 'product_id', string='Branch Lines', )
    branch1 = fields.Integer(string="branch 1", related="branch_line.qty", domain="[('branch_line.branch_id','=', 3)]", )
    branch2 = fields.Integer(string="branch 2", related="branch_line.qty", domain="[('branch_line.branch_id','=', 4)]", )

class CustomBranchLine(models.Model):
    _name = 'custom.branch.line'
    _description = 'Branch Line Record'

    branch_id = fields.Many2one('custom.branch', string='Branch')
    product_id = fields.Many2one('custom.product', string='Product')
    qty = fields.Integer(string="QTY", required=False, )

您应该使用计算字段为branch1和branch2字段获取正确的值：

branch1 = fields.Integer(string="branch 1",compute="_get_branch")
branch2 = fields.Integer(string="branch 2",compute="_get_branch")

@api.multi
def _get_branch(self):
    for line in self:
        line.branch1 = self.env['custom.branch.line'].search([('branch_id','=',3)],limit=1).qty
        line.branch2 =         self.env['custom.branch.line'].search([('branch_id','=',4)],limit=1).qty

Odoo：域无法与相关字段一起使用
