Subject: Re: Rails: Counter problem

Actually, my real application is a bit more complicated and it
does have the 'belongs_to :forum, :counter_cache => true ' in Topic
class.
Nevertheless the problem still exist because my main page should look
like this:

Forum1 NumOfTopicsinForum1 NumOfRepliesInForum1
Forum2 NumOfTopicsinForum2 NumOfRepliesInForum2
....

With Your solution I can print out the NumOfTopicsinForum without an
additional
SQL query, but i can not print the NumOfRepliesInForum (as I don't
have posts_count field in
Forum class) and there are some other minor reasons for having posts
in the Forum class.

Additionally my real Post class belongs to 3 other classes so even if
your solution was ok the problem
with wacky counters remains. Basically, I have a feeling that the
solution to my problem is simple and
I'm just missing something obvious :-)
