I have dynamic form which has a set of values. I created a partial which contains text fields which I display. Next to each of them I would like to display a label containing the title of the text. For instance First Name, and Last Name would not be known previously. How do I go about doing that? It seems that I cannot access the attributes directly. But when I use the label field, the variable name in the label is displayed not the actual value.

Well! This was a reflection of how new I am to rails. You can do this by using f.object.{attr_name}
and that worked.
f.object.{attr_name}
didn't work for me, but f.object[:attr_name]
did.
What about:
f.object.send(attr_name)
That would be the Rubyish way.
