Sorry about that :-)

Play_list is an array of arrays returned at the beginning of the create
method. Each array contains a topic id. Array[0] needs to be converted
to a list of the question id's contained in that topic. That is all
taken care of.

The sequence of the question id's in array[0] needs to be manipulated,
in more than one method.

So... I need to either duplicate the code in several methods (in the
same controller) or create a method that is called by the controllers
multiple methods. The model method seems right but play_list does not
seem to be an instance as it is not yet created and is not yet an
attribute of the model
