Note that the `:wrap_object` expects an object that is _callable_, so any `Proc` will do. So you could as well use it to do some fancy extra initialisation (if needed). Note that the `:wrap_object` expects an object that is _callable_, so any `Proc` will do. So you could as well use it to do some fancy extra initialisation (if needed).
But note you will have to return the (nested) object you want used.
E.g. E.g.
``` ```
link_to_add_association('add something', @form_obj, :comments, :wrap_object => Proc.new {|comment| comment.name = current_user.name }) link_to_add_association('add something', @form_obj, :comments,
:wrap_object => Proc.new { |comment| comment.name = current_user.name; comment })
``` ```
> A cleaner option would be to call a function that performs this initialisation and returns `self` at the end.
