This should return the path to file in this format: /users/avatar/xxx/xx/original/filename
instance.send(attachment).path
Also, in my case i had to use something like:
file_path = k.send(value).path.split('/system', 2).secondbecause it exists locally and path had system as a prefix.
For Digital Ocean Spaces, could you check the ETag of an object for the checksum rather than downloading the entire thing? Their docs say the ETag is "an MD5 hash of the object".
When I run the migration (with the provided code) I get:
ArgumentError: wrong number of arguments (given 1, expected 2..3)
/Users/nicknoble/products/Lnky/db/migrate/20180531013954_convert_to_active_storage.rb:14:inprepare'up'
/Users/nicknoble/products/Lnky/db/migrate/20180531013954_convert_to_active_storage.rb:14:in
Same here! :/
Same here :(
When running migration:
ArgumentError: You tried to define an enum named "industry" on the model "Company", but this will generate a instance method "horeca?", which is already defined by another enum.

I think this is because of the first line, when we require all the models. I just commented that line out and worked without that kind of error.
No (offical) way to use validations (https://github.com/thoughtbot/paperclip#validations) for Active Storage yet. Mayor bummer …
Heres a fix for it: https://github.com/igorkasyanchuk/active_storage_validations
Instead of building the URL in the def key method, can't I use the same thing I used in checksum?
url = attachment.url
I'm attempting to modify this migration to transition from Shrine to Active Storage.
get_blob_id = LASTVAL() was returning the id from the attachments table, NOT the blob_id. I had to change it to get_blob_id = "(SELECT max(id) from active_storage_blobs)". Any thoughts on this?
