Hi

A few things I'm wondering - if anyone can answer without too much
trouble!  (I know if I google enough I could learn what's going on..)

I'm trying to make a string of url parameters, like this:
"&#{unless category_name.nil?; 'category=' + category_name; end}"
and like that for about three different variables.  Is there a faster
way?

Is there anything detrimental to using lots of partials or nested
partials?  Does each one mean the sever has to open another file every
time its not cached - and so slow things down?

I have a partial which makes some ajax tabs.  This (for reasons
currently beyond me!) means that the authenticity token changes, giving
the ActionController::InvalidAuthenticityToken error.  One suggested fix
is to only protect put/delete/update, but that seems undesirable.  Do I
want to be useing with => authenticity_token here?  how?

Thanks in advance!!
