From 70e684a681352e95fb990747ef6dd7183da333a8 Mon Sep 17 00:00:00 2001 From: Jamis Buck Date: Tue, 8 Jan 2013 11:20:47 -0700 Subject: view_cache_dependency API A declarative API for specifying dependencies that affect template cache digest computation. In your controller, specify any of said dependencies: view_cache_dependency { "phone" if using_phone? } When the block is evaluated, the resulting value is included in the cache digest calculation, allowing you to generate different digests for effectively the same template. (Mostly useful if you're mucking with template load paths.) --- actionpack/test/controller/caching_test.rb | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) (limited to 'actionpack/test/controller/caching_test.rb') diff --git a/actionpack/test/controller/caching_test.rb b/actionpack/test/controller/caching_test.rb index 2428cd7433..eb5eeb0423 100644 --- a/actionpack/test/controller/caching_test.rb +++ b/actionpack/test/controller/caching_test.rb @@ -296,6 +296,24 @@ class CacheHelperOutputBufferTest < ActionController::TestCase end end +class ViewCacheDependencyTest < ActionController::TestCase + class NoDependenciesController < ActionController::Base + end + + class HasDependenciesController < ActionController::Base + view_cache_dependency { "trombone" } + view_cache_dependency { "flute" } + end + + def test_view_cache_dependencies_are_empty_by_default + assert NoDependenciesController.view_cache_dependencies.empty? + end + + def test_view_cache_dependencies_are_listed_in_declaration_order + assert_equal %w(trombone flute), HasDependenciesController.view_cache_dependencies + end +end + class DeprecatedPageCacheExtensionTest < ActiveSupport::TestCase def test_page_cache_extension_binds_default_static_extension deprecation_behavior = ActiveSupport::Deprecation.behavior -- cgit v1.2.3
