Odoo 12 : Changes are not visible when updating existing module

Question

我正在尝试更新 website_ajax_login 模块 中模板名称 ajax_login_template.xml 中的一些静态文本。

我已经恢复了一个现有的转储文件，没有任何错误。

问题是在 developer mood 更新应用后我看不到变化。

但是当我使用新数据库而不是转储版本并全新安装 website_ajax_login_module 时，更改会按预期显示。为了简化我的问题和我所做的如下:

First Attempt

Step 1 -> Restore dump file into a database.

Step 2 -> Update template.xml file

Step 3 -> Activate Developer Mood and upgrade the App. i.e. `website_ajax_login` 

Result ===> Changes Not Visible.

Also if I click on top menu item "Customize -> HTML/CSS editor". No windows open at the right side of the screen.

Second Attempt 

Step 1:  Go to web database manager view
Step 2: Create a database (not restore list in the first attempt)

Step 3: Install website_ajax_login app

Result ====> Changes Visible I made in the template.xml file.

if I click on top menu item "Customize -> HTML/CSS editor". The window opens on the right side of the screen without any problem.

此错误是否涉及缓存等。使用我的数据库的转储版本时，我看到错误日志如下。

作为测试，我创建了一个新模块，新模块一切正常。
