javascript - 奥杜 v16 : assets-frontend Error after uninstall custom module (migrated from v13)

Question

在我从 Odoo v13 迁移到 v16 后，卸载了一个自定义模块 (website_signup_info)，该模块只有一个 crontroller.py 和一个 js 文件:signup.js，并且没有其他结节具有此依赖项:

自定义模块 website_signup_info 的

__manifest__.py:

# -*- coding: utf-8 -*i-
{
    'name': ' website_signup_info : handle custom fields in signup ',
    'version': '13.0.2.0.20',
    'category': 'Website',
    'summary': """handle custom fields in signup """,
    'description': "handle custom fields in signup ",
    'depends': ['website','auth_signup','auth_oauth','portal'],
    'assets': 
           { 
             'web.assets_frontend': [ 
              '/website_signup_info/static/src/js/signup.js',  
              ],
            },
    'installable': True,
}    

卸载它并访问网站后，我收到了有关无法访问 Assets 前端的错误:

Error while render the template
Exception: Unallowed to fetch files from addon website_signup_info
Template: website.layout
Path: /t/html/head/t[3]
Node: <t t-call-assets="web.assets_frontend" t-js="false"/>
Error has occurred while rendering the model: website.layout 
and evaluating the following expressions:

知道如何解决吗？ 我应该使用 SQL 从数据库中删除 Assets 吗？

Answer 1

我们在卸载 Odoo 模块时遇到了类似的问题(几乎相同的错误，只是使用了 web.assets_backend 和 Odoo v15.0 而不是 v16.0)。 Odoo 安装可能已从之前的旧版本迁移到 Odoo v15.0，但我们不确定。

解决方案是首先重新安装模块(使用 Odoo CLI)以消除错误，手动启用 Debug模式，进入“设置”->“技术”->“ Assets ”，找到相关 Assets 并将其删除。然后照常卸载模块。您或许还可以使用 SQL 删除 Assets ，而无需重新安装模块。

我猜测为什么会发生这种情况，因为 Odoo 曾经以不同的方式处理这些 Assets ，并且在迁移时没有考虑到这一点。卸载模块时， Assets 未被删除，从而导致此错误。
