Re: Ruby on Rails?

My main concern with regards to RoR pertains to the EOF side of things.

I have what I consider a fairly small web application yet it requires
relatively heavy use of EOF.

Some of the EOF features I depend on are:

- Peer editing contexts. I use an EC for each page so that if the user
abandons changes they are not accidentally saved when they do something on
another page. This also is necessary for fully integarating unsaved objects
into the object graph.

- Automatic many-to-many join table management

- Snapshoting, I am not a fan of state-less applications

- EOQualifier, I use this heavily for our report builder

- Temporary global IDs for for fully integrating unsaved objects into the
object graph. You need something in place of the PK.

- Faults, for efficiency in both the application and development.

That's off the top of my head.

Can anyone that has used RoR/Active Record tell me if any/all of these
specific pieces of EOF exist in RoR?

Thanks,
