【问题描述】：

我想将我的 pdf 报告另存为附件，以便我可以从该报告中制作一些附件的 zip 文件。

    pdf = self.env.ref('module_name..report_id').render_qweb_pdf(self.ids)
    b64_pdf = base64.b64encode(pdf[0])
    # save pdf as attachment
    name = "My Attachment"
    return self.env['ir.attachment'].create({
        'name': name,
        'type': 'binary',
        'datas': b64_pdf,
        'datas_fname': name + '.pdf',
        'store_fname': name,
        'res_model': self._name,
        'res_id': self.id,
        'mimetype': 'application/x-pdf'
    })

我从HERE 获得了适用于 odoo 13.0 版的解决方案，但它在 odoo 14.0 版中效果不佳。它说



Odoo Server Error

    raise ValueError('%s: "%s" while evaluating\n%r' % (ustr(type(e)), ustr(e), expr))
Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/admin/odoo/odoo-14/odoo/http.py", line 639, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)

    raise exception.with_traceback(None) from new_cause
ValueError: <class 'AttributeError'>: "'ir.actions.report' object has no attribute 'render_qweb_pdf'" while evaluating
"action = env['wgs.form.1721.a1.list'].generate_attachments(env.context.get('active_ids'))"

我尝试过来自不同站点的类似解决方案，但它产生的结果与此类似。请帮忙。我认为这是 odoo-14 中的新功能。我也是odoo开发的新手，所以我不太了解

【解决方案1】：

pdf = self.env.ref('module_name..report_id')._render_qweb_pdf(self.ids)

你必须像这样放_render_qweb_pdf。

【解决方案2】：

def action_get_attachment(self):
        pdf = self.env.ref('project2.tr_cetificate_action_id')._render_qweb_pdf(self.ids)
        b64_pdf = base64.b64encode(pdf[0])
        name = "My Attachment"
        return self.env['ir.attachment'].create({
            'name': name,
            'type': 'binary',
            'datas': b64_pdf,
            # 'datas_fname': name + '.pdf',
            'store_fname': name,
            'res_model': self._name,
            'res_id': self.id,
            'mimetype': 'application/x-pdf'
        })

此代码适用于版本 14。
