Error going through the "Getting Started" tutorial

Hi,

I get this error on step 9 of the Getting Started tutorial:

NoMethodError in PostsController#index

undefined method `accepts_nested_attributes_for' for #<Class:
0x23fbc48>

Does someone know if it's a bug?

Cheers,

Beren

Hi Beren, can you provide some details about your development environment?

For example, OS, ruby -v, gem -v, rails -v.

This is an edge rails feature AFAIK, supposed to be in 2.3
