如何在Odoo中继承没有ID的模板? [英] How to inherit a template with no ID in Odoo?
问题描述
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.就是这样:
I am trying to show the date a change was made in a task. To do this, I need to inherit the template of the widget "mail_thread". That template hasn't an id in its definition. This is it:
<?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.
In my module, I need to replace the <span> tag in order to show the date.
那么，如何继承该模板并替换标记?
So, how to inherit that template and replace the tag?
推荐答案
客户端模板有不同的继承机制(Web模板，在<templates>标记内定义，在加载时与客户端中的javascript编译"在一起)和服务器端模板(通常，视图必须包含在__openerp__.py文件的数据列表中，在启动/升级odoo服务器时会被编译").
There are different inheritance mechanism for client side templates (web templates, defined inside a <templates> tag, "compiled" with javascript in the client when loading it) and server-side templates (usually views, must be included in the data list in the __openerp__.py file, 'compiled' when launching/upgrading the odoo server).
您先使用<t t-extend="template_name">扩展Web/小部件模板模板，然后再扩展一个或多个
<t t-jquery="jquery_selector" t-operation="operation">的行为有点类似于xpath，但是客户端方面更强大".
您不需要ID，继承基于模板名称. (t-name指令)
You extend web/widget templates templates using <t t-extend="template_name"> followed by one or more
<t t-jquery="jquery_selector" t-operation="operation"> which acts kinda like xpath, but client side and more 'powerful'.
You don't need ids, inheritance is based on the template name. (t-name directive)
- Server-Side view inheritance
- Client-Side template inheritance:
模板继承用于就地更改现有模板， 例如将信息添加到其他模块创建的模板中.
Template inheritance is used to alter existing templates in-place, e.g. to add information to templates created by an other modules.
模板继承通过t-extend指令执行，该指令 以要更改的模板名称作为参数.
Template inheritance is performed via the t-extend directive which takes the name of the template to alter as parameter.
然后使用任意数量的t-jquery执行更改 子指令:
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>
<t t-extend="base.template">
<t t-jquery="ul" t-operation="append">
<li>new element</li>
</t> </t>
t-jquery指令采用CSS选择器.该选择器用于 扩展模板，用于选择指定了上下文的节点 进行t操作:
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:
- 附加
节点的主体附加在上下文节点的末尾(在上下文节点的最后一个子节点之后) - 前置
节点的主体位于上下文节点之前(在上下文节点的第一个子节点之前插入) - 之前
该节点的主体被插入到上下文节点之前 - 之后
该节点的主体被插入到上下文节点之后 - 内部
节点的主体替换了上下文节点的子节点 - 替换
该节点的主体用于替换上下文节点itsel - 无操作
如果未指定t运算，则模板主体将解释为javascript代码，并使用上下文节点以此形式执行
- 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
