Rails - Nov 2006 - 2 "belongs_to :counter_cache => true" updates 1 counter ??

I have podcasts with comments.  Each comment has a user.  When I post a 
comment, the podcast''s comments_count increments but the
user''s
comments_count does not.  I think my issue lies in the way I''m saving 
the comment (from within podcast_controller.  Don''t currently have a 
comment controller), but don''t know how to do it any other way.  Both 
podcasts & users tables have the comments_count field as 
integer/default=0.

comment.rb:
belongs_to :podcast, :counter_cache => true
belongs_to :user, :counter_cache => true

podcast.rb:
has_many :comments

user.rb:
has_many :comments

My form tag is sitting in a view coming off my podcast_controller.rb 
file:
<%= form_tag :action => "comment", :id => @podcast %>

Here is my podcast_controller#comment method:
  def comment
   @comment = 
Podcast.find(params[:id]).comments.create(params[:comment])
   @comment.user_id = current_user.id  # I have ActsAsAuthenticated 
installed
   @comment.save
    flash[:notice] = "Added your comment."
    redirect_to :action => "show", :id => params[:id]
  end

I get the new comment, I see the flash notice, comments_count increments 
in the podcast table, the correct user id is entered into the user_id 
field in comments table, but NO increment on the comments_count field in 
the users table.

I sense I may need to create a comments controller and put a create 
method in there.  But how would I call that method from a view off my 
podcast_controller ?

Or could it be that because I am grabbing the user id from 
current_user.id (which gets the id from session[:user] I believe) the 
comments model isn''t associated with the correct user and is simply 
populating the user_id field blindly?  I don''t know what magic happens 
with the objects as opposed to providing an id...if there''s any dif at 
all?

Here''s the solution!  Got it off the rails IRC channel.  Love those 
guys!

Still in my podcast controller:

def comment
  @comment = Podcast.find(params[:id]).comments.create(params[:comment])
  @comment.user = current_user  #This was the offending line!
  @comment.save
  flash[:notice] = "Added your comment"
  redirect_to :action => "show", :id => params[:id]
end

I don''t think I can extrapolate how to extend this correctly if I ever 
had the need for three belongs_to, but for now, this is perfect.
