I am new on rails, I want to store file in attachment_fu db_files table.

Unfortunately attachment_fu does not support the same attachment "interface" for :storage => :db_file as it does for :storage => :file_system , but there's a plugin that fills the void here :

https://github.com/kares/attachment_fx

Extends the file interface for the :db_file backend (@see attachment_fu :storage option). The database backend interface mimics the :file_system storage, the db data is on-demand downloaded into the public directory (the target path prefix is customizable with the :path_prefix option).

You basically use the :file_system methods like You're used to with the :db_file backend eg photo.public_filename(:small) . As a bonus You can enjoy some useful helpers from the owning model :

user.has_photo?
user.photo_path(:small)
user.photo_full_path
