When I do lesson6 of Rails Tutorial (by Michael Hartl),there is a problem:1 error prohibited this user from being saved:Password can't be blank.
gem 'bcrypt-ruby'
This is my User model
class User < ActiveRecord::Base
has_many :microposts
attr_accessor :name ,:email
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :name, presence: true, length: { maximum: 50 }
validates :email, presence: true , format: { with: VALID_EMAIL_REGEX }
before_save { self.email = email.downcase }
has_secure_password
end
I've created user and now appears
Processing by UsersController#create as HTML
Parameters: {"utf8"=>"✓", "authenticity_token"=>"4TpdKJZ3BeSxpH4pWUK4L1LwzBvJmBo/4MHnYlGQsmQ=", "user"=>{"name"=>"tom", "email"=>"tom@gmail.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}, "commit"=>"Create User"}

The User Controller
class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
# GET /users
# GET /users.json
def index
@users = User.all
end
# GET /users/1
# GET /users/1.json
def show
end
# GET /users/new
def new
@user = User.new
end
# GET /users/1/edit
def edit
end
# POST /users
# POST /users.json
def create
@user = User.new(user_params)
respond_to do |format|
if @user.save
format.html { redirect_to @user, notice: 'User was successfully created.' }
format.json { render action: 'show', status: :created, location: @user }
else
format.html { render action: 'new' }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /users/1
# PATCH/PUT /users/1.json
def update
respond_to do |format|
if @user.update(user_params)
format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: 'edit' }
format.json { render json: @user.errors, status: :unprocessable_entity }
end
end
end
# DELETE /users/1
# DELETE /users/1.json
def destroy
@user.destroy
respond_to do |format|
format.html { redirect_to users_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_user
@user = User.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def user_params
params.require(:user).permit(:name, :email)
end
end
How to solve this problem "Unpermitted parameters"? thanks
