The comment app sends a series of signals to allow for
comment moderation and similar activities. See the introduction to signals for information about how to register for and receive these
Sent just before a comment will be saved, after it’s been sanity checked and
submitted. This can be used to modify the comment (in place) with posting
details or other such actions.
If any receiver returns False the comment will be discarded and a 400
response will be returned.
This signal is sent at more or less the same time (just before, actually) as the
Comment object’s pre_save signal.
Arguments sent with this signal:
Sent just after the comment is saved.
Sent after a comment was “flagged” in some way. Check the flag to see if this
was a user requesting removal of a comment, a moderator approving/removing a
comment, or some other custom user flag.
