its isn't core to RSpec. One the of the focuses of RSpec is on the documentation aspects of tests. Unfortunately, its often leads to documentation output that is essentially lies. Consider this spec:

User =, :email)

describe User do
  subject {"bob") }
  its(:name) { should == "bob" }

1. Enable git templates:
git config --global init.templatedir '~/.git-templates'
This tells git to copy everything in ~/.git-templates to your per-project .git/ directory when you run git init
2. Create a directory to hold the global hooks:
mkdir -p ~/.git-templates/hooks
3. Write your hooks in ~/.git-templates/hooks
4. Make sure the hook is executable.

I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:
