From 26573ad7e67e64d6db222877cf2853920c2c7dae Mon Sep 17 00:00:00 2001 From: David Yip Date: Sun, 3 Jun 2018 19:41:54 -0500 Subject: [PATCH] Thread scopes through #matches?. #454. Also add an apply_to_mentions attribute on Glitch::KeywordMute, which is used to calculate scope. Next up: additions to the test suite to demonstrate how scoping works. --- app/lib/feed_manager.rb | 8 +-- app/models/bookmark.rb | 6 +-- app/models/glitch/keyword_mute.rb | 53 ++++++++++++------- app/models/glitch/keyword_mute_helper.rb | 12 ++--- ...apply_to_mentions_flag_to_keyword_mutes.rb | 17 ++++++ db/schema.rb | 4 +- .../models/glitch/keyword_mute_helper_spec.rb | 14 ++--- spec/models/glitch/keyword_mute_spec.rb | 46 ++++++++-------- 8 files changed, 99 insertions(+), 61 deletions(-) create mode 100644 db/migrate/20180604000556_add_apply_to_mentions_flag_to_keyword_mutes.rb diff --git a/app/lib/feed_manager.rb b/app/lib/feed_manager.rb index 3a2dcac68..74794f00c 100644 --- a/app/lib/feed_manager.rb +++ b/app/lib/feed_manager.rb @@ -153,7 +153,7 @@ class FeedManager def filter_from_home?(status, receiver_id) return false if receiver_id == status.account_id return true if status.reply?
