text: Hello
  My controller creates an instance of a module class.
  The module resides into the /vendor folder.
  /vendor/plugins/my_client/lib/client.rb
  This class, or all this app, has been done by someone that apparently
  know much more about ruby than me.
  As long as I make changes inside this class, its ok. For example, I
  added new code inside one function. No problems.
  The problem, the big problem, is that it seems I cannot create new
  things in this class. If I create a
  def testfunc
  str = ‘str’
  end
  and then I try to call it from the controller, then I get an undefined
  method-error.
  The definition of the function is before the private-directive. So it
  is visible.
  If I substitute the call to testfunc to one existing one, then I dont
  get any error.
  Why? Im not good at ruby. So I was thinking if maybe there is some
  place where all the functions of the module are defined. So I searched
  all the code, but I never found a place where the functions are
  declared.
  Well, Im in stuck. Any advice?
