Question

I just added :confirmable but am now getting an error:

NameError in Devise::RegistrationsController#create

undefined local variable or method `confirmed_at' for #<User:0x000001025db288>

I realized that after I added it, I didn’t do anything that would generate a migration.

How do I get a new migration to alter the current schema on an existing devise install?

Thanks.

Update: Here’s Devise wiki page on how to change existing table to suit Devise needs:

For Devise below 2.0
