All,

if I have an object defined as follows:

class Fred  
attr\_accessor :fields

```
  def initialize
     @fields = Hash.new
  end

```

end

If want to display the keys in Fred map in a form thus doing  
something  
like

\<%= text\_field( ‘myFred’, ‘(?? WHAT DOES THIS LOOK LIKE ??)’ ) %\>

The issue is what does the databinding expression look like and can’t  
this  
be achieve with Rails ?  
For instance if the hash contains a key ‘name’ that is the field I  
want to  
interact with on the form. This would be the equiv of struts  
dynaforms…

Any ideas ? Rails gods and goddesses, Please help…
