javascript - 如何在 qweb 报告中添加分隔符？

Question

我想在 qweb 报告中添加分隔符“,”，以获得以下结果:session1,session2,session3 而不是:session1session2session3

这是我的代码:

<tr t-foreach='sessions' t-as='session'>
      <td><t t-esc="session.name" /></td>
  </tr>

我试过

<t t-esc="', '.join(sessions).mapped('session.name')"/> 

但是我得到了一个错误，

odoo.addons.base.models.qweb.QWebException: sequence item 0: expected str instance, pos.config found
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/odoo/addons/base/models/qweb.py", line 331, in _compiled_fn

  File "<template>", line 4, in body_call_content_119
  File "<template>", line 9, in foreach_98
TypeError: sequence item 0: expected str instance, pos.config found

Error to render compiling AST

Template: point_of_sale.report_saledetails
Path: /t/t[2]/t/div/div/tr/td[2]/t
Node: <t t-esc="', '.join(sessions).mapped('session.name')"/>

有什么帮助吗？谢谢。

尝试:

<t t-esc="', '.join(sessions.mapped('name'))"/>
