我在 ubuntu 12.04 上使用 OpenERP 7。我用“list_db = False”启动了服务器。它工作正常：菜单列表已由输入字段更改。但是当我写一个不退出的数据库名称时，服务器会抛出一个异常而不是显示一条消息：例如“数据库不退出”。这是异常的文本：

OperationalError: FATAL:  database "db_test" does not exist

编辑：

我刚刚找到了这个错误的原因。请转到“ web/addons/web/static/src/js/chrome.js: line 706：您将看到该on_submit函数有一个“ if”块来验证数据库的字段是否为空。解决方法是添加第二个“ if”块来验证输入的名称是否在数据库列表中在调用do_login(db, login, password)函数之前。

不幸的是，我不知道 JavaScript 编程来解决这个问题

为了只显示消息而不是整个异常，您可以将最外层的调用包装在try/except块中：

try:
    <make your call>
except OperationalError, e:
    <evaluate e which is your exception>
