本人通过root安装了相应依赖项：

不知该问题如何理解并解决？

今天采用了一个简单粗暴的方法解决了该问题。
修复操作系统、重装odoo（内部包含postgresql）。免得产生odoo连接postgresql数据库可能会产生的问题。

指定了db_name也还是不行。

我在想，也许是原来的odoo14没有卸载干净，导致与后来的odoo15冲突，所以odoo15无法登录。

刚才在卸载odoo15时，发现也无法卸载干净。用win10自带的卸载程序，被提示“无法完全卸载”。后来，即便删除了所有安装目录下的文件，也还是留存于win10的“程序与应用”中。

●我在odoo.conf中将db_host修改成了12７.0.0.1，并重启了odoo和postgresql服务，再在浏览器中登录127.0.0.1:8069，还是不行。

●数据库的对应好象都没有错误。主机号、用户名、port号、密码都一致。

●odoo.conf文件：

●但就是用pdamin4打开数据库里，有个注释好象有问题：

但我安装的数据库路径却是：

请问到底 问题出在哪里？

@steven 在 如何判断某元素存在于 中说：

@digitalsatori 在 如何判断某元素存在于 中说：

@Steven 可以用

[('participator_ids', 'in', uid)]

把uid 放在元组的第一个元素是不对的。系统对x2M 类型字段会自动反转过滤条件的。

谢谢！
按照您所说的，反转过滤条件，模块升级没有报错。但在“应用”界面内点击过滤菜单，运行过程中出现了问题。

若方便，还请赐教。

如果你确实没有写错的话。升级模块后，有没有刷新应用界面。

问题终于解决了，原来我犯一个低级错误，在domain="[('participator_ids','in','uid')]"里将uid两边的单引号去掉后，程序恢复了正常。
