I’m interested in building a web app in which the users build their own  
forms.  
Once built, the forms work like a normal web-app form in themselves.

Basically I’m looking for a kind of meta-web-app in rails, where the  
actual app has a database containing the information describing the  
user’s app (field name, value type, etc) and holding the user’s data.

Is there anything out there like this?

I found this link  
[http://www.workingwithrails.com/railsplugin/6095-acts-as-meta-model](http://www.workingwithrails.com/railsplugin/6095-acts-as-meta-model)  
which seems to be the kind of thing I’m talking about, I’m not sure if  
the plugin exists.

Bump. Surely someone has tried something like this?

Hate to bump again, but just in case.
