From 12ef99556e97b5781ae63df39e0d153493a4bddd Mon Sep 17 00:00:00 2001 From: Eugen Rochko Date: Fri, 12 May 2017 19:09:21 +0200 Subject: [PATCH] Add conversation model, (#3016) * Add tag to Atom input/output Only uses ref attribute (not href) because href would be the alternate link that's always included also. Creates new conversation for every non-reply status. Carries over conversation for every reply. Keeps remote URIs verbatim, generates local URIs on the fly like the rest of them. * Fix conversation migration * More spec coverage for status before_create * Prevent n+1 query when generating Atom with the new conversations * Improve code style * Remove redundant local variable --- app/lib/atom_serializer.rb | 7 +++ app/models/conversation.rb | 20 +++++++++ app/models/status.rb | 43
