Beginner questions

Lo there,

I am wanting to redo our company website in rails ( it now uses php ).
I have the Agile book on the way here from Amazon. I am really new at
this, and had a couple of questions.

First off, we run three websites off of our apache server at work (
debian linux ). I know that ror can use apache instead of webbrick as a
server. Is it possible to run more than one rails app from one server
using virtual hosting (name based).

Next. We do a lot of intense graphing apps that are written in php
using a class called JpGraph. How well do rails and php play together ?
or would it be worth it to use a ruby charting and graphing app ?

lastly, I know that there are certain conventions that rails looks for
in how it uses a database. Our tables follow none of these. Would i
have to restructure my SQL tables to make use of rails? I mean, i know
that i can follow our own conventions ( which stink ) but will that
prove a configuration nightmare ? Would it be best to just restructure
everything according to rails conventions ?

I guess thats it. The reason i want to use rails is because I have just
started getting into ruby, and rails looks like a really cool way to
handle our web front end. Many many of our scripts that we use to run
the site now are php and need to be revamped anyway. I started building
the site about a year ago whilst learning php.

Anyway, please, any tips would be greatly appreciated.

thanks.

Hi nephish,

Let me just share some experiences.

  • It is fully possible to run your different rails apps behind an
    apache server. I would recommend you to set up one mongrel server (or a
    cluster of mongrel servers, read about it on the webpage) per
    application, and point your different Vhosts to those server ports.
    Apache dont have native rails support as a module, so the best way to
    go is mongrel in my opinion. There are other options like Fastcgi to
    run your app, but I myself only had bad experiences with it.

  • There should definatly be some ruby script for your graph needs. Im
    not an expert in the area, but i use FusionCharts on a site to generate
    nice looking flash graphs. If you dont want to involve flash, there
    should be some ruby script to generate graphics. Look at RMagick, but i
    reckon thats at a too low level for what your looking for.

  • I really, really recommend applying the Rails conventions on your
    database structure. It will for sure spare you lots of time later on
    with all the magic thats involved. I cant imagine my daily work today
    if it wasnt for the rails convention-related help i get :slight_smile:

Best of luck,

Richard Johansson

Gruff is a popular graphing library for Ruby. It relies on ImageMagick
and RMagick at the backend.

Hey thanks,
I had never heard of mongrel before, looks good, and simple.
And, since i need to restructure so much of our stuff anyway, i think
more and more about redoing it rails style.
I still would like to keep some of our php scripts, unless they will
create a conflict.

thanks for the tips, a lot.

Charting is a huge part of our application. After researching lots of
charting packages, including Gruff, I found ChartDirector to the best
by far. At the time there were no Ruby bindings, so I wrote our
charting code with php + ChartDirector and had Rails request graphs
from our chart server via XML-RPC. If you are absolutely tied to
JpGraph, you could use that option.

However, as of last week, there are now Ruby bindings for
ChartDirector. I’m very excited. I would love to see more Rails’ers
use ChartDirector so we could find any bugs in the Ruby bindings.

Note that I am in no way affiliated with ChartDirector or Advanced
Software Engineering, I’ve just been using it for over a year and I
really like it.

Of course, your other good option is doing the charts in Flash.

i don’t have a lot of flash experience, but i do like what i see on
your link.
the flash charting app that Richard showed me, the Fusion Charts looked
really cool.
i almost want to re-write all of that stuff anyway.

thanks for your help.
