class << self
attr_accessor :all_devices, :test
#def initialize(devices)
# @all_devices = devices
#end
end
def initialize_devices
AllDevicesController.all_devices = @devices_array
redirect_to :action => “show_all_devices”
end
Where devices_array is an array of devices.
def show_all_devices @devices_array = AllDevicesController.all_devices
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @devices }
end
end
The problem here is when accessing @devices_array in the view @devices_array is nil. I know the code is being executed in
initialize_devices because if I don’t redirect to show_all_devices I can
manipulate the @devices_array within the initialize_devices view.
However, accessing AllDevicesController.all_devices in show_all_devices
results in nil.

Anyone know why?
because in development mode your source code is reloaded between
requests (ie it is no longer the same AllDevicesController class).

This was exactly the problem I was experiencing.
Thanks Fred!
