Rails Active Support

CurrentAttributes

• Use Current to store per-request data like user, account, or timezone
• Do not store mutable state across threads or background jobs
• Always reset Current at the beginning of a request
• Declare attributes with attribute :user, :account inside the class

Core Extensions

• Prefer Rails-provided core extensions over monkey-patching
• Place any custom extensions under config/initializers/core_ext/
• Avoid reopening core classes in libraries or gems
