Re: ORM, fetching related rows of corresponding model: undefined index..

I see you are using the Packt Publishing book, ensure that your model
relations aren't misspelled or anything else it won't load the answers
and thus won't exist, in the controller do a debug on the find, that
or in the view do a pr($questions) before the foreach this will
display the array and see what exactly what is in the array.
