从 odoo 15 中的向导创建自定义 excel 报告

Question

我正在尝试使用 report_xlsx 模块从向导生成 excel 报告，但出现以下错误。

Traceback (most recent call last): File "/home/kabeer/Projects/Odoo15ce/odoo/custom_addons/report_xlsx/controllers/main.py", line 76, in report_download response = self.report_routes( File "/home/kabeer/Projects/Odoo15ce/odoo/http.py", line 535, in response_wrap response = f(*args, **kw) File "/home/kabeer/Projects/Odoo15ce/odoo/custom_addons/report_xlsx/controllers/main.py", line 32, in report_routes data.update(json.loads(data.pop("options"))) ValueError: dictionary update sequence element #0 has length 10; 2 is required

这是我所做的。

    from odoo import fields,models,api,_


    class OpenPOXlsx(models.AbstractModel):
        _name = 'report.transight.open_po'
        _inherit = 'report.report_xlsx.abstract'
        def generate_xlsx_report(self, workbook, data, partners):
            print('data',data)
            for obj in partners:
                report_name = 'Excel Report test'
                # One sheet by partner

        _description = 'OpenPO'

        purchase_order_id = fields.Many2many('purchase.order',string='Purchase Order')
        partnumber = fields.Char(string="Partnumber")
        mode = fields.Selection([('partnumber','Part Number'),('po','Purchase Order')],string="Filter by")

        def action_print(self):


            if self.mode == 'po':
                query = """my query %s """

                self.env.cr.execute(query,(tuple(self.purchase_order_id.ids),))
                datas = self.env.cr.dictfetchall()
                print('data---------',datas)
            # return self.env.ref('account_batch_payment.action_print_batch_payment').report_action(self, config=False)

            return self.env.ref('transight.open_purchase_order_print_menu').report_action(self,data=datas)

Answer 1

dictfetchall() 方法 returns 一个字典列表和 report_action 期望 data (datas) 是一个字典。

在之前的Odoo版本中，我们使用form键传递记录数据，例如：

datas = {
  'ids': active_ids,
  'model': 'hr.contribution.register',
  'form': self.read()[0]
}

要解决此问题，请将提取的值添加到数据中：

values = self.env.cr.dictfetchall()
datas['values'] = values

然后在generate_xlsx_report方法中使用values键

在调用report_action

之前确保datas是一个字典
