扩展默认模板Odoo 12

Question

我只是一步一步地按照教程学习，即使这样，我也会遇到错误。在“扩展默认标题”一章中-> https://www.odoo.com/documentation/12.0/howtos/themes.html#extend-the-default-header

在“网站/配置/应用程序”中，安装主题，然后在“网站/配置/设置”中，单击“选择主题”按钮，然后在其中选择要使用的主题。

但是，此时会出现如下错误消息：

Error:

</data>

我究竟做错了什么？是我还是本教程未更新？

为了澄清起见，尽管在追溯的底部出现了一个<data></data>标签，但这只是在这里，因为在我位于该位置的代码中，我有一个<template></template>标签。

Answer 1

经过数小时的搜索，在Internet上找到了我的问题的答案。我发现问题实际上是两个。

第一个是需要在清单 .py中的我的依赖项中附加“ website_theme_install ”应用程序。在教程的任何地方都没有说过，我也不知道为什么它已经安装在我的Odoo实例中，也许是Odoo 12.0中的默认值。这就是造成这种情况的原因。KeyError: 'theme.ir.ui.view'

第二个事实是，在网站本身继承自portal.frontend_layout模板的website.layout模板中，标头后没有div，实际上我们有一个nav，但在搜索如下标头后就没有div了：

<xpath expr="//div[@id='wrapwrap']/header/div" position="after">

所以我不得不将其更改为：

<xpath expr="//div[@id='wrapwrap']/header/nav" position="after">

因为那个位置有个导航仪。没有改变，这是抛出一个ParseError。

更改后，它运行良好。希望这对其他人有帮助
