I auto-create a category along with some object in my application.
Thus, when my user want to delete its object, I want to also delete the category. But before deleting a category, I must delete all the topics in it, and we can’t delete the _About the category_ topic.
Even if deleting the category is possible at this point (with only this topic in it), I’d like a way to not try to delete the _About_ post, and directly try to delete the category instead.
Does this topic has some kind of flag? Should I rely on the fact that it is created by the _system_ user (because it is — through my API client)?

You should be able to delete a category with the `About the category` topic still in existence. All other topics need to be deleted. The `about` topic needs to exist as it serves as the category description.

Hi Justin, thanks for the answer.

I know that the category can be deleted, I’d just like my script to not worry when it tries to delete all topics and stumble upon _About this category_, or better, that it doesn’t try to delete it. Right now I can’t differentiate wether a failed topic deletion is to be considered as a problem or just normal because it’s the _About_ topic 🙂

You can compare the category topic id on the category model to the topic id and just exclude the matches.
