Thanks for helping. The errors occurs during implementation
accepts_nested_attributes_for. I get ActionView::Template:Error
(undefined method ‘events’ for nil:class) & NoMethodError in app/views/
users/index.html.erb where line #12. See all files @

\app\models\user.rb


  class User < ActiveRecord::Base
    has_many :events, :dependent => :destroy
   accepts_nested_attributes_for :events, :reject_if => lambda { |attributes|      attributes['event_name'].blank? }, :allow_destroy => true

   attr_accessible :name
   
  end

class UsersController < ApplicationController
  
 
 respond_to :html, :xml, :js

  @users = User.all

Doesn’t look like anything to do with accepts_nested_attributes_for -
doesn’t look like you’ve assigned anything to @user in the index
