I have external file called require 'query-eval' # here the name of the file required query-eval.rb then there is this class in query-eval.rb that I want to call from my program that is saved as a different file and IS in the same directory. Following the instruction in file I had following three line code that gives error. I think it is because QueryEval is a class not a method. is there a way to call class without hassle? thank you filename='rlv-ass' # another external file qe = QueryEval(filename) qe.process_query_results(sorteddocs,1) ERROR : project4.rb:243: undefined method `QueryEval' for # (NoMethodError) -- Posted via http://www.ruby-forum.com/.
