查询问题

Question

我遇到查询问题：

$userInProjects = $this->Timesheet->RegularPost->UserInProject->find('all', array('conditions' => array('UserInProject.user_id' => $id)));

结果数组：

Array
(
[0] => Array
   (

                   )

               ( and many more ...)

           )
   )
)

我想要实现的是上面的数组，但是带有[date] =＆gt;的RegularPost仅限2010-02-01。 有没有办法在此查询中将日期'2010-02-01'传递给RegularPost？

此查询不起作用：

$userInProjects = $this->Timesheet->RegularPost->UserInProject->find('all', array('conditions' => array('UserInProject.user_id' => $id, 'RegularPost.date' => '2010-02-01')));

1054：'where子句'

中的未知列'RegularPost.date'

请帮忙。 ：）

Answer 1

您需要使用Containable行为：

$userInProjects = $this->Timesheet->RegularPost->UserInProject->find('all', array(
    'conditions' => array('UserInProject.user_id' => $id),
    'contain' => array(
        'User', 'Position', 'Project',
        'RegularPost' => array(
            'conditions'=> array( 'RegularPost.date' => '2010-02-01' )
         )
    )
));

此查询告诉Cake的ORM使用您在UserInProject中提供的id属性以及所有关联的$id，User检索所有Position条记录和Project条记录。最后，它告诉Cake的ORM检索与RegularPost属性等于UserInProject的已检索date记录关联的所有2010-02-01条记录。

UserInProject hasMany RegularPost和RegularPost belongsTo UserInProject

是的，我已经调试了2级调试。

以下是SQL查询：

SELECT `UserInProject`.`id`, `UserInProject`.`project_id`, `UserInProject`.`position_id`, `UserInProject`.`user_id`, `Project`.`id`, `Project`.`short_name`, `Project`.`full_name`, `Project`.`start_date`, `Project`.`end_date`, `Project`.`agreement_number`, `Project`.`active`, `Project`.`user_id`, `Position`.`id`, `Position`.`name`, `User`.`id`, `User`.`username`, `User`.`first_name`, `User`.`last_name`, `User`.`email`, `User`.`password`, `User`.`active`, `User`.`created`, `User`.`modified`, (CONCAT(`User`.`last_name`, " ", `User`.`first_name`, " (", `User`.`username` , ")")) AS `User__full_name` FROM `user_in_projects` AS `UserInProject` LEFT JOIN `projects` AS `Project` ON (`UserInProject`.`project_id` = `Project`.`id`) LEFT JOIN `positions` AS `Position` ON (`UserInProject`.`position_id` = `Position`.`id`) LEFT JOIN `users` AS `User` ON (`UserInProject`.`user_id` = `User`.`id`) WHERE `UserInProject`.`user_id` = 15 

（此查询由cakephp自动生成）：

SELECT `RegularPost`.`id`, `RegularPost`.`date`, `RegularPost`.`size`, `RegularPost`.`users_in_project_id` FROM `regular_posts` AS `RegularPost` WHERE `RegularPost`.`users_in_project_id` IN (11, 20) 

那么，是否可以将日期'2010-02-01'传递给第二个查询？
