问题 Active Storage stores uploads in a file structure like so: This is great if the rails app is the only software that needs to use these files. But what if the app simply serves as a means to upload the images to S3 so that some other (completely separate) service can consume them? The problem being, other developers wouldn't be able to make any sense of the directory and files, since they're labelled in a way rails can understand, but which a human cannot (e.g. what does folder named "O2" mean

问题 The problem This code: image_url('my_image.png') generates this url from within the view : http://localhost:3000/assets/my_image-d229e5de55e4f8589c78e2419221fa3ae4f9d4026f.png But when the same code is run from the controller , it generates this: http://localhost:3000/images/my_image.png Only the first url actually works. How can I generate the correct url (the one containing the fingerprint) from the controller? What I tried I found a way to make it work locally, by generating the digest

问题 Suppose there's a task rake startupscript that should run whenever the app boots, how can we automate that on heroku? I know there's a heroku scheduler but that will run the task every 10 minutes instead of just once at boot. I also know of the Procfile and believe this can be a solution, although I do not yet know how to implement (and probably more importantly, I don't want to risk breaking anything else that can be configured via a Procfile, e.g. webserver etc). A lot of the Procfile docs
