Question

I was testing my code in IRB and I typed in this:

class be
  def new_text
    text = gets()
  end
  def show_text
    puts "#{text}"
  end
end

When I typed in new_text it worked but when I typed in show_text it came up with an error:

NameError: undefined local variable or method `text' for #<BE:0xd3cc08>
        from (irb):14:in `show'
        from (irb):14:in `show'
        from C:/Program Files/Ruby1.9.2/bin/irb:12:in `<main>'

Any ideas of how to fix that?

Answer 1

Change text to be an instance variable:

class Be
  def new_text
    @text = gets()
  end
  def show_text
    puts "#{@text}"
  end
end

You’re getting the error because the show_text method is trying to access a variable called @text which hadn’t been defined in your original example.
