How to reflect database change to model

Just a friendly warning; It's *very* unlikely that you should be
changing the db schema dynamically.

Do consider having someone review your design.


Sometimes legacy databases leave you no choice but to layer the same
model over different database tables. You then have to think about how
to reference columns when presenting data to the user. I'm 'lucky' (if
anyone who has to work with legacy databases in RoR can be called
lucky), in my case I have another table which tells me what's in the
first table.
