Need suggestion on best gems for Versioning and Extending a model.

[senthil kumar]

Hi All,

We are starting a new project which will have lots of forms. Each form will represent a single table, but will have many associations to other models. 

This form's fields can be extended on the fly. Versions needs to tracked for the models and any point of time the version can be reverted back.

Is there any proper gems available for this ? I was thinking to use acts_as_versioned. But I need the models to be extended. 

And more complex thing is that we need a way to filter / sort based on that extended field. 

Thanks in advance.

With Best Regards,

Senthil
