How to create unique constraints in laravel 5.2?

How do I create unique constraints using laravel 5.2 Schema Builder?

Schema::create('my_pivot', function(Blueprint $table){

$table->increments('id');
$table->integer('table1_id')->unsigned();
$table->integer('table2_id')->unsigned();

$table->foreign('table1_id')->references('id')->on('table1');
$table->foreign('table2_id')->references('id')->on('table2');

//Here i need to add an unique constraint to 'key1' + 'key2'

});

Answer

You can pass an array to the unique method.

$table->unique(['key1', 'key2']);
