Answer 1

You should create a new migration file let's say 'add_user_foreign_key.php'

public function up()
{
    Schema::table('lists', function(Blueprint $table)
    {
         $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::table('lists', function(Blueprint $table)
    {
    $table->dropForeign('user_id'); //
    });
}  

The run

 php artisan migrate
