Active storage

Does not save files to disk until commit.

Post.transaction do
  # This one is ok. Returns true.
  @post.attachments.attach(io: StringIO.new("something...."), filename: "new-post.txt", content_type: "plain/text")
  
  # This would raise ActiveStorage::FileNotFound error.
  # Plus, you won't find any new file in the filesystem until commit.
 # @post.attachments.last.download

Try this in your rails console with rails c:

Sidekiq.redis{|r| r.get("stat:processed") }

some_data = Sidekiq.redis { |conn|
    conn.pipelined do
    conn.get("stat:processed")
    conn.get("stat:failed")
 conn.zcard("schedule")
