odoo-14 中 render_qweb_pdf 的替代方案

如何解决odoo-14 中 render_qweb_pdf 的替代方案

我想将我的 pdf 报告保存为附件，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，但在 odoo 14.0 版中效果不佳。它说

odoo Server Error

Traceback (most recent call last):

    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)
  File "/home/admin/odoo/odoo-14/odoo/http.py",line 315,in _handle_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'))"

我尝试了来自不同站点的类似解决方案，但它产生了与此类似的结果。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

解决方法

    <ContentControl.Style>
        <Style TargetType="ContentControl">
            <Style.Triggers>
                <DataTrigger Binding="{Binding YourProperty}" Value="{x:Null}">

你必须像这样放置_render_qweb_pdf。
