Question

我部署了一个网站，我希望允许用户填写表单。但是，无法写入表单，因为数据库当前是只读的！如何更改SQLite3以允许任何用户写入数据库？

这是我的Unicorn.log：

root@The-Origin-of-Foods:/home/unicorn# tail -20 log
tail: error reading ‘log’: Is a directory
root@The-Origin-of-Foods:/home/unicorn# cd log
root@The-Origin-of-Foods:/home/unicorn/log# ls
unicorn.log

好的，所以解决方案是使用chmod来更改文件的权限。我在db / production.sqlite3中找到了我的数据库。然后我用命令行输入：

chmod 777 production.sqlite3

chmod允许我更改权限和类，每种类型有3种类型：读取，写入，执行和所有者，组，其他。 777是一个数字代码，用于设置这些权限和类的值。你可以在这里阅读更多相关信息http://www.maketecheasier.com/file-permissions-what-does-chmod-777-means/
