Re: User/Admin definable forms (schemaless forms)

Look into EAV structures. Basically you build tables that map data
types (field types) to their values and the owning model by name and
id. A polymorphic behavior would do most of the work. There are a few
of on github that google finds pretty easily.

This of course doesn't do the form building work, or decide how to map
value types to input types etc. But it should give you something to
play with.
