Hi, my app is on Ruby 2.1.2 and Rails 4.1.5
like the subject states I would expect current_user.account.employees.includes(:entrances).where( 'entrances.clocked_at' => @month_range) to return all employees (to this current_user’s account) - and any entrances But I’m left with the employees that has entrances in the month_range [ that looks like this: SELECT `employees`.`id` AS t0_r0, `employees`.`name` AS t0_r1, `employees`.`last_seen` AS t0_r2, `employees`.`created_at` AS t0_r3, `employees`.`updated_at` AS t0_r4, `employees`.`punch_clock_id` AS t0_r5, `employees`.`account_id` AS t0_r6, `employees`.`born_at` AS t0_r7, `entrances`.`id` AS t1_r0, `entrances`.`employee_id` AS t1_r1, `entrances`.`clocked_at` AS t1_r2, `entrances`.`created_at` AS t1_r3, `entrances`.`updated_at` AS t1_r4, `entrances`.`entrance_type` AS t1_r5 FROM `employees` LEFT OUTER JOIN `entrances` ON `entrances`.`employee_id` = `employees`.`id` WHERE `employees`.`account_id` = 2 AND (`entrances`.`clocked_at` BETWEEN '2015-01-01' AND '2015-01-31') ORDER BY employees.id, entrances.clocked_at ] If, however, I settle for current_user.account.employees.includes(:entrances) I get all employees but than I get all the entrances loaded into memory as well [ that looks like: Employee Load (0.2ms) SELECT `employees`.* FROM `employees` WHERE `employees`.`account_id` = 2 Entrance Load (0.2ms) SELECT `entrances`.* FROM `entrances` WHERE `entrances`.`employee_id` IN (1, 2) Entrance Load (0.3ms) SELECT `entrances`.* FROM `entrances` WHERE `entrances`.`employee_id` = 1 AND (`entrances`.`clocked_at` BETWEEN '2015-01-01' AND '2015-01-31') Entrance Load (0.4ms) SELECT `entrances`.* FROM `entrances` WHERE `entrances`.`employee_id` = 2 AND (`entrances`.`clocked_at` BETWEEN '2015-01-01' AND '2015-01-31’) ] The correct statement is SELECT `employees`.`id` AS t0_r0, `employees`.`name` AS t0_r1, `employees`.`last_seen` AS t0_r2, `employees`.`created_at` AS t0_r3, `employees`.`updated_at` AS t0_r4, `employees`.`punch_clock_id` AS t0_r5, `employees`.`account_id` AS t0_r6, `employees`.`born_at` AS t0_r7, `entrances`.`id` AS t1_r0, `entrances`.`employee_id` AS t1_r1, `entrances`.`clocked_at` AS t1_r2, `entrances`.`created_at` AS t1_r3, `entrances`.`updated_at` AS t1_r4, `entrances`.`entrance_type` AS t1_r5 FROM `employees` LEFT OUTER JOIN `entrances` ON `entrances`.`employee_id` = `employees`.`id` AND (`entrances`.`clocked_at` BETWEEN '2015-01-01' AND '2015-01-31’) WHERE `employees`.`account_id` = 2 but how do I write that “the Rails way” cheers Walther -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
