Question

For this piece of code:

class myBaseClass
  def funcTest()
    puts "baseClass"
  end
end
myBaseClass.new.funcTest

I am getting an error:

NameError: undefined local variable or method `myBaseClass' for main:Object
from c:/Users/Yurt/Documents/ruby/polymorphismTest.rb:9
from (irb):145:in `eval'
from (irb):145
from c:/Ruby192/bin/irb:12:in `<main>'
irb(main):152:0> x=myBaseClass.new

When I tryx=myBaseClass.new, I get:

NameError: undefined local variable or method `myBaseClass' for main:Object from (irb):152

Has someone already encountered this problem? I don’t think my code can be wrong.

Answer 1

In ruby, all constants including class names must begin with a capital letter. myBaseClass would be interpreted as an undefined local variable. MyBaseClass would work properly.
