Hi,

i’m new to ruby and tried some code to get a small application.  
I used Webrick to get a http server:

require ‘webrick’  
include WEBrick  
s = HTTPServer.new(:Port =\> 8000)

# Add a mime type for \*.rhtml files

HTTPUtils::DefaultMimeTypes.store(‘rhtml’, ‘text/html’)

# Required for CGI on Windows; unnecessary on Unix/Linux

s.config.store( :CGIInterpreter, “#{HTTPServlet::CGIHandler::Ruby}”)

# Mount servlets

s.mount(‘/test’, HTTPServlet::FileHandler, ‘/’)

# Trap signals so as to shutdown cleanly.

[‘TERM’, ‘INT’].each do |signal|  
trap(signal){ s.shutdown }  
end

# Start the server and block on input.

s.start

and i created an rhtml file:

 Ruby Test 
## Test
 \<% require 'mysql' %\> \<% my = Mysql::new("localhost", "root", "", "books\_development") %\> \<% res = my.query("select ID,Name from books Limit 10") %\> \<% res.each { |i| puts "" } %\> 

| #{i} |

Now the problem is that i can see the html in my browser but the result  
of embedded Ruby code only in my Konsole. Could anyone give me the right  
direction.

Thanks in advance  
dirk

Before serving the rhtml file to your web client you need to run ERb  
on it and capture the result, then serve it using a different method  
than HTTP::Servlet.

I can’t remember the details off-hand but if you look at my Camping  
presentation at [http://slides.games-with-brains.net/](http://slides.games-with-brains.net/) you’ll find some  
simple examples of rolling WEBrick servers and integrating ERb is  
fairly simple. I usually just add it into the String class as a handy  
instance method:

class String  
def apply\_erb  
ERB.new(self).result  
end  
end

so when generating the output for the server you’d have a line roughly  
like:

my\_content.apply\_erb

where my\_content is the variable holding the rhtml page text, or a  
method that produces it.

Hello Ellie,

I use WEBrick and Erb too and I want get all data (a array whith 3  
columns) from a big FORM, maybe by the POST method, but I’ve no idea how  
to make this ☹

You make a reference to yours slides. I’ve tried many times to “join”  
the group and to download the file without success. And the delay of  
communication is long, long, so long !

Have you an other place to get your presentation, or the solution could  
you help me to find the right solution ? 🙂

Thanks.
