Rails3.1.3 devise (2.0.4)
I have set up a table: users using devise. But it gives an error
undefined local variable or method `unconfirmed_email' for #<User:0x00000102231218>
So I generated migration file and edited
class AddConfirmableToDevise < ActiveRecord::Migration def change change_table(:users) do |t| t.confirmable end end end
$rake db:migrate
command produces
== AddConfirmableToDevise: migrating -- change_table(:users)
[DEVISE] You are using t.database_authenticatable and others in your migration and this feature is d eprecated. Please simply use Rails helpers instead as mentioned here: https://github.com/plataformatec/devise/wiki/How-To:-Upgrade-to-Devise-2.0-migration-schema-style
rake aborted! An error has occurred, this and all later migrations canceled:
SQLite3::SQLException: duplicate column name: confirmation_token: ALTER TABLE "users" ADD "confirmat ion_token" varchar(255)
