I am not able to signup my user that is getting error while running post method for /signup route.

Please help !!!

 Rails.application.routes.draw do
  get    'signup'  => 'users#signup'

This is users controller

class UsersController < ApplicationController

  def signup
  end

  def create
    user = User.find_by(email: params[:user][:email].downcase)
    if user && user.authenticate(params[:user][:password])
        log_in(user)
        redirect_to(root_path)
    else
        flash.now[:danger] = 'Invalid email/password combination'
        render('new')
    end
end

end
