Fields_for dynamic label

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.

Could you try to explain what you want to accomplish better? Maybe give an example? I have tried to understand in order to help you but I can't understand what you need. - Petros
I have an object which has a one-to-many relation with a set of Dynamic Fields {Name,Value}. When a user is updating the dynamic fields I want to display the name of the fields as the actual label instead of the hardcoded label. Or a predetermined String value. The dynamic form is inside a partial and all data. Snippets: _form.erb <% f.fields_for :entity_values do |builder| %> <%= render "entity_value_fields", :f => builder%> <% end % _entity_value_fields.erb <%= f.label :name %> {label needs to be the dynamic name of that value} <%= f.text_field :value %> ... - sebajb

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.
