Hi slavoyar, thank you very much for your work. I don't have any problems with the demand, but I have a few small opinions on the implementation.

Our API follows the RESTful principle. The /comment interface is used to operate the comment resource table, and the /article interface is used to operate the articles resource table. However, now the article resource table only has statistical functions, so it is called count name.

So if you want to add an interface to delete all comments, I think it is more appropriate to add it to DELETE /comment. What do you think?

@lizheming Yes, this make sense to me. I will move this logic to comment controller.
