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

> **[Ruby on Rails Guides](https://guides.rubyonrails.org)**
>
> Ruby on Rails Guides

NoMethodError in PostsController#index

undefined method `accepts\_nested\_attributes\_for’ for #\<Class:  
0x23fbc48\>

Does anyone know if it’s a bug?
