When to use files to store data rather than a database?

Question

I am thinking when to use files instead of a database table for storage of data?

Example if you just have some backend settings, you could store them in a file..

Or is it best practise to have everthing in a DB?

I am using Rails as framework for my web applications.

如果您只是想设置一些要在应用程序中使用的设置，为什么不创建一个配置文件或初始化文件呢？
