Rails strong params giving wrong number of arguments exception

I'm trying to implement simple authorization following by certain tutorial.

class AuthController < ApplicationController

    layout 'public'
    def auth_user
        user = User.authenticate(login_params)
        if user
            session[:user_id] = user.id
            redirect_to(:action => 'home')
        else
            flash[:notice] = "wrong username or password"
            flash[:color]= "invalid"
            render "login"  
        end
    end

  private

  def login_params
    params.require(:login_data, :password)
  end

end

and getting the exception at params.require saying 'wrong number of arguments (2 for 1)'. can't understand, what am I doing wrong? rails 4.1.1

The require method, or more specifically ActionController::Parameters#require, only takes a param key as argument.

As you can see from the Rails 4.1.1 source code:

# File actionpack/lib/action_controller/metal/strong_parameters.rb, line 172
def require(key)
  self[key].presence || raise(ParameterMissing.new(key))
end
