Hi bellow is the script.
I think its failing at
if #{f['name']} =~/asw1-v2r7c9-bry/
brydc << #{f['name']}
end
but dont understand where is the problem , i just get Internal Server
Error if i enable
this line brydc << #{f['name']}
I am quite new and i am from php background.. and in php it was easy to
troubleshoot ..
#!/usr/bin/ruby
require 'cgi'
require 'mysql'
cgi = CGI.new
m = Mysql.new("localhost","root","","report")
r = m.query("select device.name as name, hardware.name as model
device.hardware=hardware.id")
brydc=Array.new
r.each_hash do |f|
if #{f['name']} =~/asw1-v2r7c9-bry/
brydc << #{f['name']}
end
end
puts cgi.header
puts "<html>
<!DOCTYPE html>
<html>
<head>
<title> Per DataCenter </title>
<link rel='stylesheet' href='style.css' type='text/css' />
</head><body>
<h1>Switch Per DataCenter </h1>
</div>
<div>
<table border='1'>"
brydc.each do |f|
puts "<tr>"
puts "<td>#{f['name']}</td>"
puts "</tr>"
end
puts "</table>
</div>
</body></html>"
thanks for your help.

Assuming your hash values are strings, just remove it. if f['name'] =~ /asw1-v2r7c9-bry/ brydc << f['name'] end

It looks like you are using a unix operating system, so you can tail the log file: $ tail -f 'log_file_name' ...which will show the last lines from the log file and update them in real time as new lines are written to the log file. Or, you can use something like here: a) http://rubygems.org/gems/cgi-exception or b) http://eradman.com/posts/ruby-cgi.html
