Odoo xml 树视图未显示所有预期结果

Question

我正在尝试对每个产品的销售和采购 t运行saction 进行报告，因为它从不同的模型（表）中选择字段，我必须根据 sql 查看现在的问题是，在 xml 树视图中，它没有 return 返回它应该返回的所有结果，我检查了 sql 视图查询并运行 postegres，它 return 有 30 行，但 xml 树视图上显示的只有 17

下面的代码

class ProductProfileReportView(models.Model):
    _name = "product.profile.report"
    _auto = False

    product_id = fields.Many2one(comodel_name="custom.product", string="Product", required=False, )
    action_type = fields.Char(string="Type")
    create_date = fields.Datetime(string="Date")
    invoice_id = fields.Many2one(comodel_name="custom.purchase", string="Invoice", required=False, )
    qty = fields.Integer(string="Qty")
    supplier_id = fields.Many2one(comodel_name="custom.supplier", string="Supplier", required=False, )
    customer_id = fields.Many2one(comodel_name="custom.customer", string="Customer", required=False, )
    price = fields.Float(string="Price")

    @api.model_cr
    def init(self):
        """ Event Question main report """
        tools.drop_view_if_exists(self._cr, 'product_profile_report')
        self._cr.execute(""" CREATE OR REPLACE VIEW product_profile_report AS (

Answer 1

最有可能的问题出在这里ROW_NUMBER() OVER (ORDER BY product_id) AS id, 所有 id 值都必须是唯一的且非零。而且当你过滤和分组时，ids 应该是稳定的。
