accepts_nested_attributes_for not working per docs

Reported by Mikel Lindsaar | January 24th, 2010 @ 04:46 AM | in 3.0.2

I am updating the Rails Guides and found that accepts_nested_attributes_for does not seem to be working per documentation.

On Rails master cloned and vendor'd as of 24 Jan, 2010, Ruby 1.8.7

The gist of the matter is at:

accepts_nested_attributes does not seem to be working per docs on Rails 3. The following code snippets produce:

 undefined method `_delete' for #<Tag:0x1034414a8>

when you try and view a post that has a tag using the usual idiom:

  <div class="field">
    <%= tag_form.label :_delete, 'Remove:' %>
    <%= tag_form.check_box :_delete %>

This does work as advertised on Rails 2.3.5

You can clone the whole Rails 3.0 app just waiting for your gem bundle at

Assigning it to Jose because you touched the code last :)
