Rails ActiveRecord where to_sql is changed (maybe broken....)
# Rails 4.2.3 with mysql2
[1] pry(main)> User.where("id" => 1).to_sql
=> "SELECT `users`.* FROM `users` WHERE `users`.`id` = 1"
[2] pry(main)> User.where("users.id" => 1).to_sql
=> "SELECT `users`.* FROM `users` WHERE `users`.`id` = 1"
[3] pry(main)> User.where("db.users.id" => 1).to_sql
=> "SELECT `users`.* FROM `users` WHERE `db`.`users.id` = 1"
# [3] is invalid SQL because `db`.`users.id`

pry bug??

env

  • windows XP
  • ruby 2.0.0
  • pry 0.9.11 ~ 0.9.12.4

constant Pry::REPL::Readline is undefined through pry_class.rb

    if defined?(Bond) && Readline::VERSION !~ /editline/i
 config.completer = Pry::BondCompleter.start
