Forum: Italian Ruby user group altro errore: can't dup Symbol

Eccomi di nuovo qui...

sembra che tutto giri quando mi inchiodo con un "can't dup symbols"...
ho cercato su google l'errore ma c'è una sola segnalazione e non sembra
fare al caso mio.

Disastro....

Se qualcuno mi dà una mano.....grazie in anticipo


#controller

def download
        send_file(params[:path_to_file], :disposition => :attachment)
end

Grazie !
