module InheritedResources::ShallowHelpers
Shallow provides a functionality that goes on pair with Rails’ shallow. It is very similar to “optional” but it actually finds all the parents resources instead of leaving them blank. Consider the following example:
belongs_to :post, :shallow => true do belongs_to :comment end
When accessed as /comments/1, Inherited Resources will automatically get the post resource so both objects are actually accessible through the views.
However, when using optional, Inherited Resources wouldn’t actually bother with finding the parent object.
