after playing with the DB interaction I''m moving on to doing some file
IO. but I''m completly lost as to where to put the code and how to call
it.
I''m trying to get a list of files in a directory and it''s not
obvious to
me how to do this in Rails via a controller method.
so ruby code is
Dir.entries("testdir").last
and html code is
<%= Dir.entries("testdir").last %>
or
<% mylastfile= Dir.entries("testdir").last %>
<%= mylastfile %>
but how do I get this into the application controller
(./app/controllers/application.rb) so I can say anywhere
<%= mylastfile %>
?
