Trying to migrate a module from Odoo 11 to Odoo 12 but am facing the inheriting syntax error:


During handling of the above exception, another exception occurred:

        </div>
    </div>
    </xpath></template>


And this is the Inhereted Class of the web module:


<div class="container mb-5 pb-5">

<div t-attf-class="card border-0 mx-auto mt-5 bg-100 {{login_card_classes}} o_database_list" style="max-width: 300px;">

Hi,

 The class o_database_list doesn't exists in web.login_layout template in Odoo 12.

  <xpath expr="//div[hasclass('o_database_list')]" position="replace">

The below is web.login_layout template in Odoo 12 and you have to use the right xpath as per your need from the below template

<template id="web.login_layout" name="Login Layout">
<t t-call="web.layout">
<t t-set="html_data" t-value="{'style': 'height: 100%;'}"/>
<t t-set="head">
<t t-call-assets="web.assets_common" t-js="false"/>
<t t-call-assets="web.assets_frontend" t-js="false"/>
<t t-call-assets="web.assets_common" t-css="false"/>
<t t-call-assets="web.assets_frontend" t-css="false"/>
</t>
<t t-set="body_classname" t-value="'bg-100'"/>

<div class="container mb-5 pb-5">
<div t-attf-class="card border-0 mx-auto mt-5 bg-100 {{login_card_classes}} o_database_list" style="max-width: 300px;">
<div class="card-body">
<div t-attf-class="text-center pb-3 border-bottom {{'mb-3' if form_small else 'mb-4'}}">
<img t-attf-src="/web/binary/company_logo{{ '?dbname='+db if db else '' }}" alt="Logo" style="max-height:120px; max-width: 100%; width:auto"/>
</div>
<t t-raw="0"/>
<div class="text-center small mt-4 pt-3 border-top" t-if="not disable_footer">
<t t-if="not disable_database_manager">
<a class="border-right pr-2 mr-1" href="/web/database/manager">Manage Databases</a>
</t>
<a href="https://www.odoo.com?utm_source=db&amp;utm_medium=auth" target="_blank">Powered by <span>Odoo</span></a>
</div>
</div>
</div>
</div>
</t>
</template>
