Rails - Jul 2006 - filters

Hi,

 ...i''m fairly new to ruby on rails, so maybe this is a simple
question,
but i''ve been racking my wits for a while now, but i can''t
figure out
why this isn''t working...

i''m implementing some kind of a questioniere, so that when a user picks
a certain answer, the value of that answer goes into a session variable 
that stores the amount of points the user has accumilated, so that in 
the end i can pick that out and use it for my application (specifics, 
not important)
so everything is good, until i want to reset the session to zero;
i want to reset the session when a certain params variable is equal to 
zero - - i have a params[:question_number] in the action ( the uri looks 
like www.localhost:3000/polls/questioniere/1?question_number=0)
so i decided to run a

before_filter :zeroize_point_if_start_questioniere

where i defined it

def..
 if params[:question_number] == 0
   @session[:aquired_points] = 0
 end
end

it didn''t work.
i checked to see if the before_filter was running, and it was(i put a 
false in there, and the page wasn''t rendered) and i also checked to see
if the params[:question_number] was read as zero, and the test also 
worked out fine. (it read a zero)

the only thing left to be the problem is that because it is a 
before_filter, it doesn''t read the params[:question_number] until after
the before_filter takes place.
but, then, how am i supposed to zeroize the points (according to the 
page_number)? am i missing the problem, or is there something else i''m 
missing?

thanks for any help,

u

Try:

   if params[:question_number] == "0"

I suspect that''s what''s going on.
