ruby - Sinatra/Rack params[] in before block -

-

i'm making site using sinatra, going well, or until needed access params[] hash in before block.

basically, i'm trying this:

before   if params[:forum_id]     @forum = forum.find(params[:forum_id])     build_breadcrumbs(@forum.parents)     # ... more code, snipped keep short   end end

but thing is, can't call params[] hash in before block, have ideas?

the reason i'm putting code in before block because i'd rather not have go , put in every 1 of get , post blocks every page.

from docs:

before filters evaluated before each request within same context routes , can modify request , response.

since happens before actual request, can't access request parameters. can put repetitive code method , call in route blocks.
