Adding table index through rails

Rails
1

Hello,
could someone please tell me how I can add a Mysql table index through
my rails app. without using a migration, ie from within my app ?

ie how I can call the add_index() method here >
ActiveRecord::ConnectionAdapters::SchemaStatements.add_index().

I don’t quite understand what I need to include or require for the
add_index method to become available for me to use.

thanks in advance,

Hal

Why would you even want to do that? Normally the migrations are the
only part of your code that should change your DB schema, so I suspect
that you’ve either got very unusual needs or a design problem.

What are you ultimately trying to achieve here?
