    respond_to do |format|
      format.html { redirect_to contacts_url }

end

This is the Model file "contact.rb"

class Contact < ActiveRecord::Base
  attr_accessible :email, :fullname, :mobile, :note, :surname
end

Please help me solve this error i'm stuck.

Answer 1

Everything looks right. Run rake db:migrate then restart the server.

Edit:

if you have created the table already and you want to recreate it then drop the old table first

Add this to the top of the migration

def change
  drop_table contacts
  .... #create the new contact table
end
