Basically taking a file that the user browsed on their local computer
(in this case my own computer since I'm testing it), manipulate the
file directory name and run it through an outside program. The outside
program creates a file that the user can view and I don't want the
ruby code activating again when the user reopens the show page.

This is the code for my first solution:

In Controller
-------------------
def show
@order = Order.find(params[:id])
respond_to do |format|
if @order then
format.html {redirect_to '/display', :notice => "This task has
already been created"}
format.xml {render :xml => @order}

else
order = @order.logfile
@log_file_cut = order.gsub(/[\w ! # $ % ^ & * + -]+\.log$/,
'*.log')
system('C:\analog_6.0\analog.exe', @log_file_cut)

time = @order.created_at.strftime("%m%d%y_%H%M")
watchforfile = "C:\\rails_project\\test2_copy\\public\\output\
\errors.txt"
File.rename watchforfile, watchforfile+".#{time}.html"

StatusReport.deliver_confirm(@order) #sends email when analog
has completed

format.html {redirect_to(:action => 'edit')} # show.html.erb
format.xml { render :xml => @order }
end
end
rescue ActiveRecord::RecordNotFound
logger.error("Attempt to access invalid task #{params[:id]}")
flash[:notice] = "Invalid task"
redirect_to "/display"
end

If you think about it, it'll run the first set of code when I create a
new object, not the actual ruby code to runs the outside program

My Second Solution In Controller
-----------------------------------------------
after_filter :analog, :only => [:create]

protected
def analog
order = params[:logfile]
@log_file_cut = order.gsub(/[\w ! # $ % ^ & * + -]+\.log$/,
'*.log')
system('C:\analog_6.0\analog.exe', @log_file_cut)
end
end

Thanks for the help :)
