From 580d250166d97bd5c2b0526be737d02806e577c2 Mon Sep 17 00:00:00 2001 From: Yorick Peterse Date: Thu, 26 May 2016 13:38:28 +0200 Subject: Refactor Participable There are several changes to this module: 1. The use of an explicit stack in Participable#participants 2. Proc behaviour has been changed 3. Batch permissions checking == Explicit Stack Participable#participants no longer uses recursion to process "self" and all child objects, instead it uses an Array and processes objects in breadth-first order. This allows us to for example create a single Gitlab::ReferenceExtractor instance and pass this to any Procs. Re-using a ReferenceExtractor removes the need for running potentially many SQL queries every time a Proc is called on a new object. == Proc Behaviour Changed Previously a Proc in Participable was expected to return an Array of User instances. This has been changed and instead it's now expected that a Proc modifies the Gitlab::ReferenceExtractor passed to it. The return value of the Proc is ignored. == Permissions Checking The method Participable#participants uses Ability.users_that_can_read_project to check if the returned users have access to the project of "self" _without_ running multiple SQL queries for every user. --- app/models/snippet.rb | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'app/models/snippet.rb') diff --git a/app/models/snippet.rb b/app/models/snippet.rb index 0a3c3b57669..407697b745c 100644 --- a/app/models/snippet.rb +++ b/app/models/snippet.rb @@ -30,7 +30,8 @@ class Snippet < ActiveRecord::Base scope :public_and_internal, -> { where(visibility_level: [Snippet::PUBLIC, Snippet::INTERNAL]) } scope :fresh, -> { order("created_at DESC") } - participant :author, :notes + participant :author + participant :notes_with_associations def self.reference_prefix '$' @@ -100,6 +101,10 @@ class Snippet < ActiveRecord::Base content.lines.count > 1000 end + def notes_with_associations + notes.includes(:author, :project) + end + class << self # Searches for snippets with a matching title or file name. # -- cgit v1.2.1
