Simple stuff in rails rhtml

Rails
1

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 %>

?

class XController < Application

def stuff
@mylastfile= Dir.entries(“testdir”).last
end

end

stuff.rhtml

<%=mylastfile%>

Or put it in a before filter in application.rb so it will be
available everywhere;

class ApplicationController < …

before_filter :get_last_file
attr_reader :mylastfile
protected

def get_last_file
@mylastfile = Dir.entries(“testdir”).last
end

end
