Remove all data from Active Storage?

问题

I would like to know how can I delete all data from Active Storage or even resetting Active Storage? There is any way to do that? Thank you in advance!

NOTE: I'm using Rails 5.2

回答1:

This question challenged me, so I did some test on my dummy app with local storage.

I have the usual model User which has_one_attached :avatar

On local storage files are saved on /storage folder, under subfolders named randomly with a string of two characters.

Informations related to files are stored in two tables:

• ActiveStorage::Attachment
• ActiveStorage::Blob

To completely clean the two tables, I did in rails console:

ActiveStorage::Attachment.all.each { |attachment| attachment.purge }

This command deletes

• All record in that table: ActiveStorage::Attachment.any? #=> false
• All the blobs: ActiveStorage::Blob.any? #=> false
• All the files located under /storage subfolders; of course, subfolders are still there empty.

The ActiveStorage still works poperly.

I expect the same behaviour for remote storage, having the right privileges.

On my local development environment, whenever I perform rails db:reset, I also run rm -rf storage to clear all previously-saved files. Rails will automatically recreate the storage directory the next time a file is uploaded.
