Hello, i've got a question. How to preform displaying comment as a thread if i have models like this?

A comment can have multiple subcomments, so this model won't work. Replace sub_comment with parent = models.ForeignKey(..., related_name='subcomments'). Then you will be able to say comment.subcomments which will give you a related object manager, so comment.subcomments.all() will be a query of all subcomments that you can iterate over.
