I was going through this section in the laravel documentation:

I saw the below line of code:

Syntax: [ Download ] [ Hide ]

$table->foreign('user_id')

      ->references('id')->on('users')

      ->onDelete('cascade');

I am not quite understanding the onDelete part , can somebody please explain that to me ?

Thank you.
Gautam.

You have a user model. Comments belong to a user. With cascading deletes, deleting a user would also delete all their comments.
