Ruby on Rails

And I am also super confused as to the notion of 'memorising'.  What does that mean?  Kids memorise the alphabet and times tables, what does that metaphor mean in terms of Ruby and Ruby on Rails? Memorising is a process of repeatedly iterating through a series that must eventually be held in one's memory.  Does Rails have some neural process of educating itself in neural memorising?

OK, thanks.  I have gone for memorising the intermediate values in the
test filter as I know they are not going to change within a request.
I had hoped there might be some clever way of massaging the
before_filter syntax that would provide a solution but I suspect that
is not possible.
