Amelia Bedelia Learns to Code
summary
Concrete examples of beginner Rails mistakes and how to fix them: edit schema directly breaks the workflow—use timestamped migrations and run them; use scaffold for everything adds unwanted controllers, views and JSON endpoints so generate only what’s needed; confusion over rake routes vs migrations; piling on gems causes dependency pain and upgrade trouble; params vs database columns misleads developers; use datetime not date for far‑future times. Short anecdotes include a false Ruby bug and an app that still runs after fixes.
