I get this error

NoMethodError in UsersController#update  undefined method `update_attributes' for #<User id: 1,   first_name: "Bob", last_name: "Cool",   created_at: "2021-03-10 06:06:13.238325000 +0000",   updated_at: "2021-03-10 06:06:13.238325000 +0000">  

I want to edit the user information with the form like this ;

This is my users_controller.rb ;

before_action :set_user, only: [:show, :edit, :update]    def update      if @user.update_attributes(user_params)        redirect_to root_path      else        redirect_to edit_user_path(@user),         error: @user.errors.full_messages.join(', ')      end    end    private    def set_user      @user = User.find(params[:id])    end      def user_params      params.require(:user).permit(:first_name, :last_name)    end  

This is my edit.html.rb

<p>    <%= form_with model: @user, url: user_path(id: @user.id), method: :put, local: true do |form| %>      <%= render 'form', form: form %>    <% end %>  </p>  

This is my _form.html.erb

<%= form.label 'First Name: '%>  <%= form.text_field 'first_name' %>  <br/>  <%= form.label 'Last Name: '%>  <%= form.text_field 'last_name' %>  <br/>  <%= form.submit 'Submit' %>  

I try to look at @user, but when it came to update_attributes, it gives this error.
