pmatsinopoulos / bug_on_active_record_when_first_or_create
Created November 25, 2013 20:48
Demonstrates a bug on ActiveRecord that occurs when one uses `Model.where(....).first_or_create(....)`. The `where(....)` is used also in any `Model.query` that takes place before the `first_or_create! returns. In the following test, the last assertion fails.
unless File.exist?('Gemfile')
File.write('Gemfile', <<-GEMFILE)
source 'https://rubygems.org'
gem 'rails', github: 'rails/rails'
gem 'sqlite3'
GEMFILE
system 'bundle'
