Question

I’m trying to change something i did in 2.8 to 3.

What it does is build a blank object in the model from the show action in the controller like so.

@project.tasks.build

and then in the show view i can do something like this

<% form_for @project do |c| %>
  <% c.fields_for :tasks,  @project.tasks.last do |p| %>
      <%= p.text_field :name, :label => 'add task' %>
  <% end %>

  <%= submit_tag '+' %>
<% end %>

in this instance it would show just the blank record for entry.

in another instance i could remove .last and have all the related tasks editable from the show action of the project.

how do I do this in Rails 3? because it’s giving me this error.

undefined method `name' for #<Array:0xb2b33d8>
