Marnen,
I do need fields_for, I am getting at data 2 levels deep in
associations (main table + association + association) and I need to
update the contents of the associations.
I am just learning how to use 'fields_for' so forgive me if I sound
like I don't know what I'm talking about.
My understanding is that 'fields_for' will iterate through the
collection, hence working with one element/object of the collection in
each iteration. If I need an attribute from the element/object at each
iteration, how would I know which element to access with
@my_object.my_collection? I don't even know if there is an index I can
use to get to the element I need as in @my_object.my_collection
[my_index], hence allowing me to do something like:
<%= @my_object.my_collection[my_index].my_attribute %>
In any case, I found a line of code "hidden" in the documentation that
gave me a clue to find what I needed:
<% if project_fields.object.active? %>
As it turns out you can access the object that 'fields_for' is using
by just using method 'object' on the block object ("fieds_for_object"
in the sample below):
<% form_for :my_object, @my_object, :url => { :action => "my_action" }
do |form| %>
<% form.fields_for :my_collection do |fields_for_object| %>
<%= fields_for_object.object.my_attribute %> # <<< This is
what I was looking for
Thanks for the insight, though.
