From 64ef37b89de806f49cc59e011aa0ee2039c82c46 Mon Sep 17 00:00:00 2001 From: Akihiko Odaki Date: Fri, 28 Aug 2020 19:31:56 +0900 Subject: Introduce ApplicationController#cache_collection_paginated_by_id (#14677) * Replace incorrect use of distinct with group Some uses of ActiveRecord::QueryMethods#distinct pass field names but they are incorrect for the current version of Rails. ActiveRecord::QueryMethods#group provides the expected behavior and benefits performance. See commit 6da24aad4cafdef8d8a2c92bac2002a5fc2fe9c8. * Introduce ApplicationController#cache_collection_paginated_by_id ApplicationController#cache_collection_paginated_by_id fuses ApplicationController#cache_collection and Paginable.paginate_by_id. An advantage of this method is that it prevents from modifying scope which Paginable.paginate_by_id may provide. ApplicationController#cache_collection always return an array and there is no possibility of the scope modification. It is also clear for a programmer, considering the implication of "cache". This method can also emit more efficient queries by using Cacheable.cache_ids before calling Paginable.paginate_by_id. --- app/controllers/accounts_controller.rb | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) (limited to 'app/controllers/accounts_controller.rb') diff --git a/app/controllers/accounts_controller.rb b/app/controllers/accounts_controller.rb index db77b628c..d97d88fd9 100644 --- a/app/controllers/accounts_controller.rb +++ b/app/controllers/accounts_controller.rb @@ -28,8 +28,7 @@ class AccountsController < ApplicationController end @pinned_statuses = cache_collection(@account.pinned_statuses, Status) if show_pinned_statuses? - @statuses = filtered_status_page - @statuses = cache_collection(@statuses, Status) + @statuses = cached_filtered_status_page @rss_url = rss_url unless @statuses.empty? @@ -142,8 +141,13 @@ class AccountsController < ApplicationController request.path.split('.').first.ends_with?(Addressable::URI.parse("/tagged/#{params[:tag]}").normalize) end - def filtered_status_page - filtered_statuses.paginate_by_id(PAGE_SIZE, params_slice(:max_id, :min_id, :since_id)) + def cached_filtered_status_page + cache_collection_paginated_by_id( + filtered_statuses, + Status, + PAGE_SIZE, + params_slice(:max_id, :min_id, :since_id) + ) end def params_slice(*keys) -- cgit
