Monkey patching ActiveStorage::Attachment gets lost
active storage public url
active storage permanent url
active storage get url
active storage direct upload
active storage attachment url
So I decided to add an
url attr_accessor to ActiveStorage::Attachment objects.
In development the patch holds for a while until it seems to "have been lost". Meaning it works for few minutes, then it does not work anymore. Then I need to restart the server in order to get the patch applied again. I believe I am not patching correctly and I would need advises in that mater.
Here is what I tried:
First try :
module ActiveStorageUrl extend ActiveSupport::Concern included do attr_accessor :url end end ActiveStorage::Attachment.send :include, ActiveStorageUrl
class ActiveStorage::Attachment < ActiveRecord::Base attr_accessor :url end
And by the way in both case it's loaded with this:
So when it work I have no error message, but after a while the patch "diseapear" (lacking better terms), and I get the following error, telling me my attr_accessor is not there anymore. Rails must have reloaded ActiveStorage classes and my patch is lost.

You are probably losing your monkey patch because the code gets reloaded and your ext/active_storage/attachment isn't re-required.
You can tell Rails to run a callback at startup and every time code is reloaded like this.
Rails.configuration.to_prepare do require 'ext/active_storage/attachment' end

Going to where it's defined:
Anyway it might have to do with how
attr_accessor works, I would try:
def url @url end def url=(url) @url = url end
attr_accessor (which is a C function actually).
Otherwise a really really hacky way to solve this would be to check for
ActiveStorage::Attachment.instance_methods.include?(:url) and monkey patch / include / prepend when not present.
