# In Rails 5.2, we have to hook at `on_load` on the blob themeselves, which is
# not ideal.
#
# Rails 6 adds support for `.on_load(:active_storage_attachment)`, which is
# cleaner (as it allows to enqueue the virus scan on attachment creation, rather
# than on blob creation).
ActiveSupport.on_load(:active_storage_blob) do
  include BlobSignedIdConcern

# When an OpenStack service is initialized it makes a request to fetch
# `publicURL` to use for all operations. We intercept the method that reads
# this url and replace the host with DS_Proxy host. This way all the operation
# are performed through DS_Proxy.
