So I’m following along in https://github.com/plataformatec/devise/wiki/How-To:-Add-:confirmable-to-Users when I get to

Create a New Migration

I’ll recreate the migration they recommend here.

class AddConfirmableToDevise < ActiveRecord::Migration
  # Note: You can't use change, as User.update_all will fail in the down migration
  def up
    add_column :users, :confirmation_token, :string
    add_column :users, :confirmed_at, :datetime
    add_column :users, :confirmation_sent_at, :datetime
    # add_column :users, :unconfirmed_email, :string # Only if using reconfirmable
    add_index :users, :confirmation_token, unique: true
    # User.reset_column_information # Need for some types of updates, but not for update_all.
    # To avoid a short time window between running the migration and updating all existing
    # users as confirmed, do the following
    execute("UPDATE users SET confirmed_at = NOW()")
    # All existing user accounts should be able to log in after this.
    # Remind: Rails using SQLite as default. And SQLite has no such function :NOW.
    # Use :date('now') instead of :NOW when using SQLite.
    # => execute("UPDATE users SET confirmed_at = date('now')")
    # Or => User.all.update_all confirmed_at: Time.now
  end

  def down
    remove_columns :users, :confirmation_token, :confirmed_at, :confirmation_sent_at
    # remove_columns :users, :unconfirmed_email # Only if using reconfirmable
  end
end

My question: Why is the migration

``

rails g migration add_confirmable_to_devise


`?`

``

`Wouldn't the better name be`

``

```
rails g migration add_confirmable_to_users
```

?

Am I missing something?
