Question

I’m getting an error when signing up using Devise. I am switching from a session-based authentication system I previously set up to Devise.

I installed Devise and have this in my model:

devise :database_authenticatable,  :registerable, :confirmable,
       :recoverable, :rememberable, :trackable, :validatable

This is my migration:

class AddDeviseUserTable < ActiveRecord::Migration
  def self.up
    create_table(:users) do |t|
      t.database_authenticatable :null => false
      t.recoverable
      t.rememberable
      t.trackable
      t.confirmable
      t.encryptable

      t.timestamps
    end

    add_column :users, :name, :string

    add_index :users, :email,                :unique => true
    add_index :users, :reset_password_token, :unique => true
    # add_index :users, :confirmation_token,   :unique => true
    # add_index :users, :unlock_token,         :unique => true
    # add_index :users, :authentication_token, :unique => true
  end

  def self.down
    drop_table :users
  end
end

I also have this in my routes:

root :to => "videos#index"
devise_for :users
resources :users do
  member do
    get :following, :followers
  end
end

The error I get when signing up is:

NameError in Devise/registrationsController#create

undefined local variable or method `encrypt_new_password' for #<User:0x1032a8cb8>

Why am I getting this error? How do I fix it?

Answer 1

There is no encrypt_new_password method in the Devise source code so I suspect this method was left behind when you switched from your previous authentication system to Devise. I would search through your application code for the string encrypt_new_password and see what you can find.

Probably something in your User model that needs more cleanup. In particular look for any obsolete before and/or after callback in your User model since the failure occurs during a call to User#save.
