"Password can't be blank" Rails Rails 4.2.4 - ruby-on-rails

Question

Like other posts, I'm getting an error "Password can't be blank" even though the password is filled in. I've added this wrap_parameters :user, include: [:username, :email, :password, :password_confirmation] to my UsersController but with no luck. Here is my Controller:
class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
wrap_parameters :user, include: [:username, :email, :password, :password_confirmation]
# 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)
puts "*********"
puts user_params
respond_to do |format|
if #user.save
format.html { redirect_to #user, notice: 'User was successfully created.' }
format.json { render :show, status: :created, location: #user }
else
format.html { render :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 { render :show, status: :ok, location: #user }
else
format.html { render :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, notice: 'User was successfully destroyed.' }
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(:username, :email, :password, :password_confirmation )
end
end
And here is my Model:
class User < ActiveRecord::Base
has_secure_password
attr_accessor :username, :email, :password, :password_confirmation
EMAIL_REGEX = /[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}/i
validates :username, :presence => true, :uniqueness => true, :length => { :in => 3..20 }
validates :email, :presence => true, :uniqueness => true, :format => EMAIL_REGEX
validates :password, :confirmation => true #password attr
validate :confirm_password_match
validates_length_of :password, :in => 8..20, :on => :create
before_save :encrypt_password, :prep_data
after_save :clear_password
def prep_data
self.email = email.downcase
self.username = username.downcase
end
def encrypt_password
if password.present?
self.password_salt = BCrypt::Engine.generate_salt
self.password_digest = BCrypt::Engine.hash_secret(password, password_salt)
end
end
def clear_password
self.password = nil
end
def confirm_password_match
if self.password != self.password_confirmation
errors.add(:password, "Passwords must match")
errors.add(:password_confirmation, "Passwords must match")
end
end
end
Any help would be appreciated ...
