This particular (fictitious) Comment model apparently has one required argument, comment, which is being set to the value new_comment that has been passed into the post_comment routine. The next line saves the created comment to the DB. The real point of the example, though, is how the session is used to track whether a comment has been posted using this session yet, and to prevent more than one comment per session.

Re: confused with session chapters in djangoproject
Dear Karen,
thanks for your reply. Actually in my learning I try to follow the
code which is provide in the book to understand how it works. It
sounds silly but from above code, I really didn't get what below line
trying to do :
c = comments.Comment(comment=new_comment)
somebody kindly help to clarify me, thank you.

That example code (which doesn't actually include "from django.contrib
import comments" in the doc, which is a clue the example is not actually
referring to the Django contrib.comments add-on) is trying to illustrate how
to set and use session variables. As the example is focused on sessions,
the referenced models aren't necessarily provided by Django. The next
example uses a ficticious "Member" model which you won't find in Django
either. These particular examples are not meant to be cut-and-pasted into
your own code, they are simply trying to illustrate how you might use
sessions with your own models.
