Hi @ all,
I have the following scenario: User A views a page with 3 comments,
and add's a new comment. Now User B logs in and views the same
page. This User already read the first three comments and now I
want that User B get's some kind of visual hit(orange triangle or
something like that), that a new comment was added since his last
visit.
How should I aproach this Problem?
Any ideas?
Thanks a lot.
This is not something that is currently built in XWiki. Right now the
default way to get notified of new comments is by using RSS feeds or
by using an email notifier plugin to send emails when new comments
are added.
That said you're free to do whatever you want but you'll have to code
it yourself. You'll need to remember what user has seen what, you'll
need to define what "viewing a comment" means, whether the user has
to push a button to signify he has view a comment, etc.
BTW the same applies to pages too.
I'm not sure how you'd hook into xwiki to update the counters when
the user has viewed a page or a comment though, which is why I was
hinting at the button above. In any case, a user may navigate to a
page but without reading it so you'll need to differentiate both
cases and the button makes the most sense I think.
An easy way would be to add a TagClass object to the page with the
name of the user who's marked the page as viewed. Then you could
easily run queries to know what pages have not yet been viewed by a
given user.
To do all this you'll probably need to modify some templates.
Hope it helps,
