ruby on server side

11-29-2010

Hi,
I am new to this forum. so forgive me if my post replicating old post.
Ok I have a ruby script with xml input file. ruby script extract
required info from xml file and present in html output with help of
nokogiri lib.
Ruby script is working fine. right now, we need to install ruby and
nokogiri on all machines to run ruby script. I want to put it like a
website. so i configured apache over my ubuntu machine. its working
fine. i can access index page on server from all machines.

What i want?

I want to design html page with form tag like:
<form action="server address"
enctype="multipart/form-data" method="post">
<p>
Please specify a file<br>
<input type="file" name="datafile" size="40">
</p>
<div>
<input type="submit" value="Send">
</div>
</form

So whenever user select xml file and press send. input file should go to
ruby script on server and html output will be generated. user get output
over his/her browser. I dont know how to do it

i am trying to figure
it out.

You'll want to check out one of the many Ruby web frameworks. If all you
want is something simple like this, I'd suggest using Sinatra:
http://sinatrarb.com/

Since you're using Apache, I'd suggest phusion passenger to get it talking
with Sinatra: http://www.modrails.com/

this looks quite complicated to me

is there any way, i can just invoke ruby script on server side?
Also, how i can feed input tag of form as input to my ruby script?

You mean using CGI? Its possible. You will need to configure your web server
for it. Its slow though.

Check out the ruby CGI library. I would guess that is a good starting point
for what you want to achieve.
http://ruby-doc.org/core/classes/CGI.html

For something simple, you really cant beat Sinatra. It is not typical to
make Ruby web programs just using CGI, or have PHP-like deployment.

If you can configure Apache, you're going to find this easy

Have a look at the sinatra book:

http://sinatra-book.gittr.com/

or this video:

http://rubyconf2008.confreaks.com/li...-services.html

All that is covered in both of those links.

Cheers,

Ok guys, thnx for the answers.. i am freaked out with all experiments

here is the code snipshots:
index.php:
<html><body>
<form action="upload.php" enctype="multipart/form-data" method="post">
<p>
Please specify a file to Parse:<br>
<input type="file" name="file" id="file">
</p>
<div>
<input type="submit" value="Parse">
</div>
</form>
</body>
</html>

upload.php:
<?php
if (//some check)
{
//some code
}
else
{
//some code
system('ruby -v'); // This is giving proper output i.e ruby version
system('ruby myprogram.rb'); // no action
}
?>

myprogram.rb is executing fine over shell but when i try to execute via
upload.php, nothing is happening. Any idea why ruby not working on
server side when accessing via upload.php ?

do i need to do anything on apache side?

i dont have any ruby handler installed on apache? is this could be the
reason?

I checked with getcwd(); // current working directory on server

In this case, myprogram.rb lies in same directory as current working
directory. do you think, its still path problem?

current working directory and location of ruby program is same

Good Afternoon,

Can I ask the stupid question? Why not recode the ruby script in PHP if you
are unwilling to do this the right way and use something along the lines of
Sinatra et al.?
