[Rails] Coding a migration to change a column's attribute

[RichardOnRails]

Hi All,

I want a migration to change the Amount column of the Expense table to
the precision/scale to 10/2.

It's easy to say in one sentence.  It's a little harder to do.

1 Ran: ruby script/generate migration ChangeExpenseTbl_AmountCol
2.Got db/migrate/20100313180401_change_expense_tbl_amount_col.rb
3.Modified the migration as follows:

class ChangeExpenseTblAmountCol < ActiveRecord::Migration
  def self.up
    class Expense
      change_column :amount, decimal :precision=>10, scale=>2
    end
  end

  def self.down
  end
end

This looks like it could be DRYed to this:

class Expense < ActiveRecord::Migration
  def self.up
      change_column :amount, decimal :precision=>10, scale=>2
  end

  def self.down
  end
end

Do either of these look correct?

Thanks in Advance,
Richard
