Fields_for dynamic label

问题:

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.

回答1:

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.

回答2:

f.object.{attr_name} didn't work for me, but f.object[:attr_name] did.

回答3:

What about:

f.object.send(attr_name)

That would be the Rubyish way.
