Listing files in a directory with Rails

Listing files in a directory with Rails
http://www.winn.ws/archives/118
In a recent application I am building I needed to pull file names and directory names from a local directory. I searched all over the net for this and found nothing. After reviewing a few of rails built in functions I came across Dir.glob(). If you feed this method a path to a directory it will then come back with an array of the names and directories listed.

If you are just starting to learn PHP you first need to find a free/cheap host (I personally prefer Fly2Blue as they are cheap, easy to use and offer great services and domain registration), you are then going to need to check that your host provides PHP of some kind (over all PHP tutorials, PHP5 is preferred). Or alternatively you can install your own server software and install your own version of PHP

As a developer, you might face few requirements where you want to upload large documents, PDF's and images from your application. Then how do you manage and store such large data? Usually, traditional approach was to store those large files on web server's file system. But you also have database approach which allows you to store those large documents like PDF's, .zip files, images etc., as binary data directly in the database itself. Let's elaborate on Database approach a bit further. How do we usually store large data objects in Databases like SQL Server 2000? Ok, SQL server 2000 supports exclusive image data type to hold

13. Linkbot
Linkbot started out in #uacs on freenode, and migrated with us to the UACS IRC network. The idea was simple: people post a lot of interesting links on IRC and sometimes you want to look at them again later (or look at them when you're not at work ... you know). Linkbot collects all the links posted in the channel in a simple text file, and there is a CGI script to display them online.

Ruby on Rails is a recent entry into the world of Web application development that is rapidly gaining mindshare, even while still in beta versions. Rails succeeds by automating the creation of the most common types of Web applications while not straightjacketing you if you want to add custom or atypical requirements. Moreover, compared to many Free Software libraries that perform individual aspects of a Web application, Rails contains a nicely integrated set of tools for all aspects.

Ruby DBI is not a true connection layer. Many install it thinking that it will help them connect to their MySQL database and then they find that nothing works. Ruby DBI is an abstration layer or so called "wrapper" class that filters multiple differences in database code into a single interface. So if a Oracle database, MySQL and PostGreSQL all have different syntax for selecting a database row it will not matter in your code. In your code the selection of a row will be the same for all three.

I get a lot of emails about packing and distributing Rails applications with Tar2RubyScript and RubyScript2Exe. It obviously wasn't easy to come up with the steps that have to be taken to transform a Rails application into a standalone application. Since I never built a Rails application myself, I wasn't even sure if it was possible at all. That's why I decided to write this tutorial.

After uploading a file to your server/database you may want users to download it, and send_file works great for just that! Lets say you are allowing users to upload "gif" files to your /RAILS_ROOT/images/*username*/*thegif.gif*. Now you want to allow them to download them or other users to download the pictures. This example will provide code and database structure for you, but i will not be providing any documentation on how to upload the file just yet
