to chyba najprościej tak:
class Base
def render_to_string(options = nil, &block)
# oryginalna czarna skrzynka
end
end
# powtórne otwarcie klasy
class Base
alias :orig_render_to_string render_to_string
def render_to_string(*args, &blk)
result = orig_render_to_string(*args,&blk)
# ...
result
end
end
A.new.render_to_string
myślałem że chodzi o bardziej 'generyczne' rozwiązanie ;)
W 2.0 będą kombinatory :pre :post i :around
