在乘法SO中更改状态

你可以通过修改AbstractModel来实现

例如:

<report 
            id="agedpartnerbalance_template"
            string="Aged Partner Template"
            model="account.move" 
            report_type="qweb-pdf"
            file="account.report_agedpartnerbalance" 
            name="account.report_agedpartnerbalance"
        />


    class ReportAgedPartnerBalance(models.AbstractModel):

        _name = 'report.account.report_agedpartnerbalance'


        @api.model
        def render_html(self, docids, data=None):
            *****
            Your Logic
            docs = self.env[model].browse(self.env.context.get('active_id'))
            for doc in docs:
                doc.state = 'sent'
            *****
            docargs = {
                'doc_ids': self.ids,
                'doc_model': model,
                'data': data['form'],
                'docs': docs,
                'time': time,
                'get_partner_lines': movelines,
                'get_direction': total,
            }
            return self.env['report'].render('account.report_agedpartnerbalance', docargs)
