可替代odoo-14中的render_qweb_pdf

Question

我想将我的pdf报告保存为附件，这样我就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'
})

我从这里得到了这个适用于odoo 13.0版本的解决方案，但在odoo 14.0版本中效果不太好。上面说

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)

"action = env['wgs.form.1721.a1.list'].generate_attachments(env.context.get('active_ids'))"

我在不同的网站上尝试过类似的解决方案，但它产生了与此类似的结果。请帮忙。我认为这在odoo-14中是新的。我也是奥多开发的新手，所以我对不太了解

Answer 1

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

您必须像这样放置_render_qweb_pdf。

Answer 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'
})

此代码将在版本14中工作。
