Add “ON DELETE CASCADE” to existing column in Laravel

Question

I have user_id fk column in my table

$table->foreign(\'user_id\')->references(\'id\')->on(\'users\');

I should add on cascade

Answer 1

In my case, i'll need to put the col name in an array else that will be an error.

Schema::table('transactions', function (Blueprint $table) {
    $table->dropForeign(['transactions_order_id_foreign']);
    $table->foreign('order_id')
        ->references('id')->on('orders')
        ->onDelete('cascade')
        ->change();
});
