The cascadeOnDelete() method is a convenient way to define cascading behavior for foreign keys when a referenced record is deleted.

Behavior

• Automatically deletes the rows in the child table if the related row in the parent table is deleted.

Example

Schema::create('posts', function (Blueprint $table) {
    $table->id();
    $table->foreignId('user_id')->constrained()->cascadeOnDelete();
    $table->timestamps();
});

This ensures that if a user is deleted, all their related posts will also be deleted.
