6,070 PointsOops, sorry for the misunderstanding.
Sounds like what you need to do is do a new migration called AddTypeToAccounts. Then in the migration file do
def change add_column :accounts, :type, :string
Try that and then run another rake db:migrate
Amanda Wagner
6,070 PointsAre you in irb or rails console? Rails console is what you want if you're dealing with the database.
Amanda Wagner
6,070 PointsThat kind of an error usually means that it's not finding the "type" column in the Accounts table. Something may have happened with the migration. In your migration file for CreateAccounts, do you have t.string :type?

5,709 PointsHi Amanda - thanks for your reply.
I believe I'm in the rails console - this is what I'm doing in terminal:

5,709 PointsWhen I first followed Hampton's steps, I had a typo and only had t.string rather than t.string :type. I've since added and done rake db:migrate.
Amanda Wagner
6,070 PointsIs it working for you now?
Michael Baker
5,709 Pointsno -I did that before posting the errors above.
