My Rails app uses the TMail plugin, but it requires a modification to Attachment.rb.
The modification is recognized and loaded by Rails on my development machine, but in the production environment on my hosting provider (Rails Playground), the system version of TMail is loaded and not our custom version.
Online document about the best way to include or freeze gems is confusing on many sites.
Anyone have a definitive answer about the best way to approach this?
Thanks!
