[xxtg666]

更新至最新版本后，发送setu命令出现报错： _{(/st-r是自己加了命令别名)}

估计是你想看r18 但是没有添加到白名单 于是读不到数据库就是None了，或者是数据库没有初始化完成？

[xxtg666]

就是用的正常的命令，没有加r18参数 好像是数据库没初始化完成，这个怎么解决

[xxtg666]

看了一下 nonebot-plugin-tortoise-orm 的源码，好像在启动时会有一个 数据库: 连接成功 的日志，但是我的日志里没有，也没有其他报错，这是什么问题

配置的sqlite3数据库文件也没有创建

[xxtg666]

改代码测试了一下，似乎

@driver.on_startup
async def connect():

这个函数没有被调用

[xxtg666]

给这个函数加了个on_command之后手动调用，插件就能正常用了

所以问题所在是没有自动连接数据库

[kexue-z]

有问题解决前时，载入插件的时候的日志吗？

[xxtg666]

日志就是很正常的加载插件，没有任何报错什么的，关于 nonebot-plugin-tortoise-orm 插件的日志只有一个

[SUCCESS] nonebot | Succeeded to load plugin "nonebot_plugin_tortoise_orm"
[SUCCESS] nonebot_plugin_tortoise_orm | 数据库: 添加模型: nonebot_plugin_setu_now.database

[kexue-z]

用sqlite把数据库删了都没有复现出来，是不是用了别的驱动器，然后你这个帐号没有创建权限导致的？ @xxtg666
