I have a text file that has data in it which is perfectly formatted the way I want it. I have the following code in my controller to open the file and read each line into an array which I then call from my view. The problem is, I completely loose the formatting the way I''m doing it: - from my controller: <code> def index @ssh = Array.new a = File.open("/usr/bin/my_data.dat") a.each do |line| @my_data.push(line) end end </code> -from my view: <code> <%= @my_data %> </code> I''m thinking that maybe I shouldn''t put the data in an array or maybe I should somehow loop through the array in my view in order to maintain the formatting of the text file? thanks -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you just want to display data from the file, why not use @my_data = File.read(...) ?

When I do it, all my columns don''t line up:They don''t line up in this email, either :-) Are you trying to display this in PRE tags or equivalent CSS with a monospace font? Your display would probably be more robust if you parsed the file contents and put it in an actual HTML table, though.

I am still a bit baffled as to why I have to write the data to a file first, then open the file and put it in PRE tags as opposed to using PUTS statements in my original script and assigning that to a variable which gets called by my index page which still causes the format to be skewed. --- my_data.rb code: data.each do |line| a.write(line) #--this writes to my_data.dat puts line #--this puts the same data to STDOUT end --- controller code: def index @my_data = `/usr/bin/my_data.rb` #this causes data to be skewed #@my_data = File.open("/usr/bin/my_data.dat").read #this works end --- index.rthml code: <pre><%= simple_format @my_data %></pre> Perhaps the way I''m writing to STDOUT in my_data.rb is causing the skewing of my data? thanks vic -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

STDOUT.write(line) fixed the problem....thanks again for the help!
