jenssegers/mongodb migrations for creating unique index on multiple fields

Question

I need to create a Laravel migration for a unique key on multiple fields. The Mongodb command i want to map is something like this:

db.collection.ensureIndex( { a: 1, b: 1 }, { unique: true })

Is it possible with jenssegers/mongodb or with another package?

Answer 1

Schema::create('collection', function ( $collection ) {
      $collection->unique(array( 'a', 'b' ));
});
