Google Base + Rails

I am trying to create a very flexible interface for users to post items. I am very interested by the approach google has used on google base. They allow their users to create “on the fly?? as many fields as the users want to best describe their item. The way I figured they did this is by creating a data table for each input type (text, check box, number, etc…) and each of these tables have the following fields item_id, label, value.

Anyways, I would be looking to create something similar

Recap of project.

1 - One page to list items

2 - One page to add items

Each item have the following common attributes





Each item can have unlimited optional attributes

Check boxes

Number fields

Date fileds

Text box

…. other fields like google base

3 - One page to edit the items

The optional attributes have to be created on the fly probably using DOM + javascript.

I will be asking the coder to describe in 3-4 lines what approach he will use to accomplish this. Keep in minde that it is important that you check out google base in order to fully understand what I am talking about.

This is a Ruby on Rails project
