[Bug] PortalViewCount bulk create fails

[injoonH]

Describe the bug

ValueError: bulk_create() prohibited to prevent data loss due to unsaved related object 'article'.

It happens as bulk_create does not call save(). (Django: bulk_create)

The model’s save() method will not be called, and the pre_save and post_save signals will not be sent.

Expected behavior

PortalViewCount.objects.bulk_create() succeeds after Article.objects.bulk_create()

To Reproduce

python3 manage.py crawl_portal_manual --start="2024.03.25"
