I seem to recall that there was a plugin or Rake snippet that would put comments in various Model classes after running a migration? It’s a chore to have to look at db/migrate/X when I want to see which fields a given model has.
If not, I’ll write one, of course. 🙂
You may be thinking of the Annotate Models plugin at:
http://repo.pragprog.com/svn/Public/plugins/annotate_models/
I believe that does exactly what you describe, although I haven’t personally used it in a while, so can’t vouch for its behaviour on more recent Rails versions.
