Nil Object

Hi everyone I'm new to ROR. I am receiving email using ActionMailer. I need some help about the error nil object i got. Anyway i am doing rails on window platform.

At first I generate the code ruby script/generate migration CreateTables to generate the file below.

db/migrate/001_create_tables.rb: class CreateTables < ActiveRecord::Migration   def self.up     create_table(:pages) do |t|       t.column :address, :string     end     create_table(:emails) do |t|       t.column :page_id, :integer       t.column :subject, :string       t.column :body, :string     end     create_table(:attachments) do |t|       t.column :page_id, :integer       t.column :file, :binary       t.column :description, :string     end   end

  def self.down     drop_table :attachments     drop_table :emails     drop_table :pages   end end

Then in model i got a EventMailer:

class EventMailer < ActionMailer::Base def receive(email)       page = page.find_by_address(email.to.first)       page.emails.create(         :subject => email.subject,         :body => email.body       )

      if email.has_attachments?         for attachment in email.attachments           page.attachments.create({             :file => attachment,             :description => email.subject           })         end       end

end

end

Then i do these ruby script/generate model Page ruby script/generate model Email ruby script/generate model Attachment

After that i rake db:migrate

Then i got a page.rb in the model: class Page < ActiveRecord::Base   has_many :emails   has_many :attachments end

When i run ruby script/runner EventMailer.receive(STDIN.read) < ForActionMailer.txt

*Note: ForActionMailer.txt is a text file contains the email i fetched from gmail by using fetch_mail.

But i got an nil object error.

Please help. Thanks
