Grab form data nested fields

I have a rails app that used nested fields via the Cocoon gem:

_form.html.haml:

= form_for @project do |f|
   %h3 Tasks
   #tasks
      = f.fields_for :tasks do |task|
          = render 'task_fields', :f => task
      .links
          = link_to_add_association 'add task', f, :tasks
   = f.submit

_task_fields.html.haml:

.nested-fields
   .field
       = f.label :description
       %br
       = f.text_field :description
       **********HERE's WHERE I WANT TO ECHO OUT THE DESCRIPTION FOR THIS PARTICULAR TASK**
   .field
       = f.check_box :done
       = f.label :done
   = link_to_remove_association "remove task", f

What I need to do is retrieve each tasks description value on the edit page for the user.

Not sure what you mean by echo, but to get the description of task in _task_fields.html.haml you can do this:

.nested-fields
   .field
       = f.label :description
       %br
       = f.text_field :description
       = f.object.description # will show description if exists on form's object here.
   .field
       = f.check_box :done
       = f.label :done
   = link_to_remove_association "remove task", f
