Nested views

Because the V2 DSL is recursive, you can define views inside of views.

Each nested view inherits from its parent, which inherits from its parent, all the way up to ApplicationBlueprint and Blueprinter::V2::Base.

class MyBlueprint < ApplicationBlueprint
  fields :name, :description

  view :extended do
    association :category, CategoryBlueprint

    view :with_foo do
      association :foo, FooBlueprint
    end

    view :with_bar do
      association :bar, BarBlueprint
    end
  end
end

You can render nested views using dot syntax:

MyBlueprint["extended.with_foo"].render(widget).to_json

or nested Hash syntax:

MyBlueprint[:extended][:with_bar].render(widget).to_json
