ArgumentError: wrong number of arguments (3 for 2) with Better Nested Set Plugin

If you’re using the Better Nested Set plugin in your 2.1 Rails app and get an error such as

ArgumentError: wrong number of arguments (3 for 2) from /usr/lib/ruby/gems/1.8/gems/activerecord-2.1.0/lib/active_record/base.rb:2479:in `attributes_with_quotes'

upon saving your model or upon calling update_attributes, you have two options:

• Move to Awesome Nested Set, a drop-in replacement for BNS which has some additional features, among them STI (Single Table Inheritance).
• Apply this patch developed by Tony Hillerson, to your Better Nested Set plugin.

Happy nesting!
