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
