Once I have devise installed, how do I add (and remove) modules easily? - Rails 3

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.

@RadBrad that's just for `confirmable`. I am interested in all modules...not just `confirmable`. — marcamillion, Jun 05 '12 at 03:02

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

For Devise below 2.0

For Devise after 2.0

No I know how to create a migration. But with Devise, I don't know the exact names of the columns that are needed. This question is specific to devise's modules....not to rails db migrations ;) – marcamillion Jun 05 '12 at 02:58
Btw, I tried that and am now getting this error in during my `migrate`: `undefined method lconfirmable' for #` – marcamillion Jun 05 '12 at 03:34
The same wiki page explains this. Since 2.0 there are no more migration helpers. Check the new update. – Alexey Kharchenko Jun 05 '12 at 03:51

So it seems the best way to do this is via this Devise Wiki link.

I just tested it and it seems to work.
