Here is my user.rb file

class User < ApplicationRecord
has_secure_password
validates :email, presence: true, format: { with: /\A[\w.+-]+@\w+.\w+\z/, message: "must be a valid email address" }
end

Here is my registration controller.rb

class RegistrationController < ApplicationController
def new
@user = User.new
end

def create
    @user = User.new(user_params)
    if @user.save
        redirect_to root_path, notice: "Successfully created account"
    else

        render :new
    end
end


private
def user_params
    params.require(:user).permit(:email, :password, :password_confirmation)
end

end

Finally here is my form

Sign Up

<%= form_with model: @user, url: sign_up_path, local: true do |form| %>
<% if @user.errors.any? %>
