templates - 如何在Odoo中继承没有ID的模板？

Question

我试图显示在任务中进行更改的日期。为此，我需要继承小部件“mail_thread”的模板。该模板的定义中没有 id。就是这个:

<?xml version="1.0" encoding="UTF-8"?>
<template>

    <!--
        mail.Widget template used to namespace the css -->
    <t t-name="mail.Root">
        <div class="oe_mail">
        </div>
    </t>

...


                    <span t-att-title="widget.date">
                        <t t-if="widget.timerelative" t-esc="widget.timerelative"/>
                        <t t-if="!widget.timerelative" t-raw="widget.display_date"/>
                    </span>



...

</template>

在我的模块中，我需要替换 <span>标记以显示日期。

那么，如何继承该模板并替换标签？

Answer 1

客户端模板(Web 模板，定义在 <templates> 标签内，加载时在客户端用 javascript“编译”)和服务器端模板(通常是 View ，必须包含在__openerp__.py 文件，在启动/升级 odoo 服务器时“编译”)。

您可以使用 <t t-extend="template_name"> 扩展 web/widget 模板模板。后跟一个或多个<t t-jquery="jquery_selector" t-operation="operation">它的行为有点像 xpath，但客户端更“强大”。
您不需要 id，继承是基于模板名称的。 (t-name 指令)

Server-Side view inheritance

Client-Side template inheritance:

Template inheritance is used to alter existing templates in-place, e.g. to add information to templates created by an other modules.

Template inheritance is performed via the t-extend directive which takes the name of the template to alter as parameter.

The alteration is then performed with any number of t-jquery sub-directives:

<t t-extend="base.template">
<t t-jquery="ul" t-operation="append">
<li>new element</li>
</t> </t>

The t-jquery directives takes a CSS selector. This selector is used on the extended template to select context nodes to which the specified t-operation is applied:

• append
  the node’s body is appended at the end of the context node (after the context node’s last child)
• prepend
  the node’s body is prepended to the context node (inserted before the context node’s first child)
• before
  the node’s body is inserted right before the context node
• after
  the node’s body is inserted right after the context node
• inner
  the node’s body replaces the context node’s children
• replace
  the node’s body is used to replace the context node itsel
• No operation
  if no t-operation is specified, the template body is interpreted as javascript code and executed with the context node as this
