Why method of 'events' does not work?

I want to make what ActiveRecord validation errors highlighted in the browser takes a lesson from ASCIIcasts. This is my partial _errors_messages

<% if event.errors.any? %>  
<div id="errorExplanation">  
  <h2><%= pluralize(event.errors.count, "error") %> prohibited this record from being saved:</h2>  
  <ul>  
  <% event.errors.full_messages.each do |msg| %>  
    <li><%= msg %></li>  
  <% end %>  
  </ul>  
</div>  
<% end %>

this is my html file which is generated form

<%= form_for event, html: { class: "event-form" } do |f| %>
  <%= render "shared/error_messages", :target => @event %>  
  <% unless current_user %>
    <div class='row'>
      <div class='col-md-4'>
        <div class="form-group col-sm-12">
          <%= label :email, "Enter your email:" %>
          <%= text_field_tag :email, "",class: "form-control" %>

and this error browser show

undefined local variable or method `event' for #<#<Class:0x007f117cc78c30>:0x007f117cdf5c48>

event should be an instance variable in the controller, e.g., @event.
