Beginner alert.....
I am working on a database migration. I am adding inventory items to
the table. I have the data, but for the life of me, I cannot remember
where to make this file. I remember how to run the migration etc.
So where do I put the

class AddUserTable < ActiveRecord::Migration
    def self.up
      create_table :users do |table|
        table.column :name, :string
        table.column :login,  :string
        table.column :password, :string, :limit => 32
        table.column :email, :string
      end
    end

    def self.down
      drop_table :users
    end
  end
