non_active_record_model
queued
This episode of Railscasts will show you how to make a model which isn't based on Active Record. You may want to do this if a resource isn't backed by the database.

If you have a lot of logic associated with the data inside a session, you'll need some central location to put this logic. See how to create a session based model in this episode of Railscasts.

<p>If you want to know how your database schema looks like, you have three options: connect to your database and do it with <em><span class="caps">DESCRIBE</span> table</em>, check the file <em>db/schema.rb</em> or use the <strong>annotate_models</strong> plugin:</p>
<pre>
<code>
script/plugin install http://repo.pragprog.com/svn/Public/plugins/annotate_models
</code>
</pre>
<p>Now you just have to run the new rake task <strong>annotate_models</strong>:</p>
<pre>
<code>
rake annotate_models
</code>
</pre>
<p>Open one of your model files and you’ll see a new comment block that looks like this:</p>
<pre>
<code>
# == Schema Information
# Schema version: 53
#
# Table name: vendors
#
# id :integer(11) not null, primary key
# vclass :string(255)
# name :string(255)
# vid :integer(11)
# created_at :datetime
# updated_at :datetime
# creator_id :integer(11)
# updater_id :integer(11)
#
</code>
</pre>
<p>You should run the rake task every time you do a migration to keep the annotation up-to-date. It’s trivial but very helpful. I couldn’t live without this plugin.</p>

annotate_your_models

This is actually a very old trick, because annotate_models is one of the older Rails plugins. On the other hand, I realized that only a few people have heard of it.
