This may a common problem, but I created a migration to change a table that already had some information in it. The rows that were already in the tables didn’t add the additional column. Would I need to drop all the information in my table and add it back, because that would be kind of a pain to do… ---

did you by any chance copy your application and did a new migration and then went back to your old one? if thats the case, you may need to have your older application catch up.

No I don’t believe so. v I had my table with some rows of data. I created a new migration that added an additional column to the table, but the column isn’t showing up when I did a “rake db:migrate”
