Devise ERROR: Auth token has already been taken

Trying to signup in my RoR webapp give me the Devise Message "Auth token has already been taken" Also, the webapp have an API and works fine, doesn't give any message, this only happen when I'm trying to use the HTML view.

user_controller.rb

before_action :set_user, only: [:show, :edit, :update, :destroy]

# DELETE /users/:id.:format
  def destroy
    # authorize! :delete, @user
    @user.destroy
    respond_to do |format|
      format.html { redirect_to root_url }
    end
  end

  private
    def set_user
      @user = User.find(params[:id])
    end

    def user_params
      accessible = [ :name, :email ]
      accessible << [ :password, :password_confirmation ] unless params[:user][:password].blank?
      params.require(:user).permit(accessible)
    end

User.rb

  validates :auth_token, uniqueness: true
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable
  before_create :generate_authentication_token!
  def generate_authentication_token!
    begin
      self.auth_token = Devise.friendly_token
    end while self.class.exists?(auth_token: auth_token)
  end

Follow the following 1) Open Rails console 

rails console

2) Get the total count of users

user = User.all
user.count

this should be 1

3) Get the user and check the auth token

user = User.last
user.auth_token

auth token would be an empty string which is the reason your command is failing as the user doesn't have valid auth token

4) Create a valid auth token for the user

user.auth_token = Devise.friendly_token
user.save

It would create a valid auth token for the user and save it

5) Now you can run your commands and it would work perfectly

Cheers! :)

It's probably because you already have users in your db without auth_token, use Devise.friendly_token to update those users with a token
