Whilst technically it may be possible in some situations that is
certainly not the way to achieve the result you want. If it contains
data that can be recalculated then possibly use a before filter.
Alternatively the rails session variable may be the right way to go.

As I said, work right through a good tutorial and such things should
become clear, or at least less muddy.
