Question

So I am doing a small, simple project for my class and for some reason I can’t access a value using a variable.

This is my class: (I am having problems with the getAnswer method, in particular the answerArray array)

#Create random fact array class RandomFact     def initialize()         @randomNum = rand(5)     end      def getQuestion         randomNum = @randomNum         questionArray = Array.new         questionArray[0] = 'Do you liek mudkipz?'         questionArray[1] = 'Question2'         questionArray[2] = 'Three'         questionArray[3] = 'Reddit'         questionArray[4] = '4chan'          puts questionArray[randomNum]         return randomNum     end      def getAnswer(randomNum,answer)         answerArray = Array.new         answerArray[0] = 'one'         answerArray[1] = 'two'         answerArray[2] = 'three'         answerArray[3] = 'four'         answerArray[4] = 'five'          return answerArray[randomNum]     end  end 

This is my class to the class:

    randomNum = cgi['randomNum']     answer = cgi['answer']     puts newQuestion.getAnswer(randomNum,answer) 

Now the thing is that randomNum holds a value from a previous form. If I print out randomNum right under where I pull the value from the form I get it.
if I print out randomNum inside of the method getAnswer I get it.
If I print out answerArray[0] I get a value.
If I print out answerArray[randomNum] I get nothing.

It is pretty much an exact copy of the getQuestion method from above and that one works. Any input?

Answer 1

The random number is probably coming in as a string from your CGI. Cast it to an integer using randomNum.to_i and you’ll be set.
