Creating tables with "variable" field names

ruby-talk

Hi All
I'm slowly ramping up on Ruby (Ex-PERL'y), and have the following
question:
*) I'd like to create a table , but with column names which are not
fixed. So instead of doing

<Code>
def self.up
    create_table mytable do |t|
       t.column :field1, :string
      t.column :field2, :stringI'd like to do
</Code>

I'd like to do

<Code>
var1 = "field1"
var2 = "field2"
def self.up
    create_table mytable do |t|
       t.column $var1, :string
      t.column $var2, :stringWhat is the correct syntax for doing that?
</Code>
Best Regards
Kretch
