Listing 8.17 introduces the its method, which is like it but applies the subsequent test to the given attribute rather than the subject of the test. In other words,

its ( : remember token ) { should not be blank }

 

is equivalent to

it  {  @user .remember token.should not be blank }

 

The application code introduces several new elements. First, we add a callback method to create the remember token:

before save :create remember token  

 

 

This arranges for Rails to look for a method called create_remember_token and run it before saving the user. Second, the method itself is only used internally by the User model, so there’s no need to expose it to outside users. The Ruby way to accomplish this is to use the private keyword:

 

private
      def     create remember token
        # Create the token.
end
