根据用户语言或首选项语言Odoo 10更改css / less

Question

亲爱的我正在使用Odoo10。我的要求有些不同，并且在任何论坛上都找不到任何此类问题或答案。实际上，我想根据用户语言或首选项选择的语言来更改文本和图标的对齐方式。我已经创建了一个自定义模块，并且能够使用我的自定义样式。我的xml文件如下：

<odoo>
  <data>

<template id="assets_backend" name="project_extend assets" inherit_id="web.assets_backend">

<xpath expr="." position="inside">

<link rel="stylesheet" href="/project_extend/static/src/less/form_view_extra.less"/>

</xpath>

</template>

正如您在开始时所看到的那样，我包含的样式表非常有效。现在，我想比较用户/首选项语言。如果是阿拉伯语，则应包括样式表；否则，如果用户/偏好语言为英语，则不包括样式表，以便odoo中的默认对齐方式生效。任何帮助都非常感谢。
