How To: Add :confirmable to Users
Clone this wiki locally
If you find yourself needing to introduce confirmable to your
User model (stored as the
users table) after the application has already been used for sometime, you will end up marking existing users as unconfirmed in the application.
For example, assume that you have a system full of users and you need to implement email notifications for user accounts. In doing this, existing user accounts will be left unconfirmed thus unable to log in.
Here's how you can introduce confirmable to users while also marking existing users as confirmed.
devise :confirmable to your
devise :registerable, :confirmable
Then, do the migration as:
rails g migration add_confirmable_to_devise
db/migrate/YYYYMMDDxxx_add_confirmable_to_devise.rb. Add the following to it in order to do the migration.
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
You can also Generate views if haven't already
rails generate devise:views users
Do the migration
Restart the server.
If you are not using :reconfirmable (i.e leave the commented out lines as they are in the change method described above), update the configuration in
config.reconfirmable = false
Before you can actually send the confirmation mail, you need the Devise::Mailer or a custom mailer configured.
If you want to redirect the user to a specific url after they clicked the link in the confirmation email, override the after_inactive_sign_up_path in your registrations_controller:
(*** I think this part is wrong? The overwritten method should be after_confirmation_path_for in Devise::ConfirmationsController. The authors please confirm. ***)
class Users::RegistrationsController < Devise::RegistrationsController def after_inactive_sign_up_path_for(resource_or_scope) session["user_return_to"] || root_path end end
Allowing Unconfirmed Access
If you want to add a "grace period" where unconfirmed users may still login, use the
allow_unconfirmed_access_for config option (which defaults to 0):
# in Devise Initializer config.allow_unconfirmed_access_for = 365.days
Alternatively, you may want to skip required confirmation all-together:
# in User.rb protected def confirmation_required? false end
