Fix all the errors to get our tests green on Rails 5.1. 2017-08-31 12:06:56 +08:00			`class AddPostUploadsIndexes < ActiveRecord::Migration[4.2]`
PERF: `NOT IN` query is really inefficient for large tables. 2016-11-02 11:14:02 +08:00			`def change`
			`add_index :post_uploads, :post_id`
			`add_index :post_uploads, :upload_id`
			`end`
			`end`
