RubyOnRails and Intraweb

Hi

Is there any advantage in using RubyOnRails over Intraweb? I don't have much knowledge about RubyOnRails but from what I can see it is easy to use with database and handles quite a lot on its own.

I am not sure how productive it is when compared to Intraweb used with InstantObjects. Using InstantObjects I can design my model and use it to build/evolve my database. Intraweb uses Delphi designer to design Html/WebPage and there is no such tool for RubyOnRails.

There are bound to be a lot more things, but from what I can see, right now I am finding it really hard to understand how RubyOnRails can be more productive.
