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

Hi Frederick,

Thanks for taking the time to look at my newbie code. I now have both
styles:
change_column :expenses, :amount, :decimal, :precision =>
10, :scale => 2 # DSL-style
change_column( "expenses", "amount", "decimal(10,
2)" ) # C-style
working. Thank you for pointing the things I was missing when I
fumbled here.

I wont have any more problems in this area. But I'm moving on to a
new area now :-)

Best wishes,
Richard
