How can I create a composite primary key and a unique index on a table

[AmazingAkai]

I cannot find any way to create a composite primary key and a unique index on a table, for composite primary keys I found this issue ( #820 ) which isn't resolved yet but I couldn't find anything for indexes can someone tell me whats the best approach for now for implementing a composite primary key and a unique index?

@AmazingAkai For now, you can do this using empty migration and editing the run() method with raw SQL as described in this link.
