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

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

I’d like to do

`
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?
` Best Regards Kretch
