In this article, I'll walk through a basic Rails (3.2.x) setup for creating a nested resource for two models. Nested resources work well when you want to build out URL structure between two related models, and still maintain a RESTful convention. This code assumes you are running RVM to manage Ruby/Gem versions, and Git for version control.

Creating a new Rails project

$ mkdir family # create rvm gemset 
$ echo "rvm use --create ruby-1.9.2@family" > family/.rvmrc 
$ cd family # install rails 
$ gem install rails # create new rails project 
$ rails new . # version control

When starting a project that includes refinerycms-blog:

$ rake refinery:override view=refinery/pages/*
$ rake refinery:override view=layouts/*
$ rake refinery:override view=refinery/blog/shared/*
$ rake refinery:override view=refinery/blog/posts/*
$ rake refinery:override view=refinery/*
$ rake refinery:override controller=refinery/blog/*
$ rake refinery:override controller=refinery/*
