I'll have to dig in a bit to see where it broke, but it definitely looks
like the #delete method no longer works as documented on that page.
However, if you know the level you set the attribute at, you can still
delete it directly:


[1] pry(main)> require 'chef'
=> true
[2] pry(main)> n = Chef::Node.new
=> node[]
[2] pry(main)> n.default['foo'] = 'bar'
=> "bar"
[3] pry(main)> n['foo']
=> "bar"
[4] pry(main)> n.delete('foo')
=> nil
[5] pry(main)> n['foo']
=> "bar"
[6] pry(main)> n.default.delete('foo')
=> "bar"
[7] pry(main)> n['foo']
=> nil

My guess is that this changed with the new Chef 11 attribute work that
was done.  But, even if it is intentional we should get

    http://docs.opscode.com/breaking_changes_chef_11.html

and any other documentation that refers to it update.

Cheers,

Steven
