每个考试都有一个大纲,每个大纲都有一个考试。所以,我在考试模型中这样做了:
public $hasOne = 'Syllabuses'; //table: syllabuses, model: Syllabuses
从UsersController
我这样做:
public $uses = array('Setting', 'Exam', 'Syllabuses');
在UsersController
我想调用分页的方法中:
$options = array(
'fields' => array('Exam.id', 'Exam.name', 'Syllabuses.id', 'Syllabuses.name', 'Syllabuses.syllabus', 'Syllabuses.last_updated'),
'joins' => array(
'table' => 'syllabuses',
'conditions' => array('Exam.id = Syllabuses.exam_id')
)
);
$this->paginate = $options;
$this->set('syllabuses', $this->Paginator->paginate('Syllabuses'));
考试表:
---+------+
id | name |
---+------+
和课程表:
---+---------+------+----------+--------------+
id | exam_id | name | syllabus | last_updated |
---+---------+------+----------+--------------+
所以,我得到了一些错误。像这样:
错误:SQLSTATE[42000]:语法错误或访问冲突:1064 您的 SQL 语法有错误;检查与您的 MySQL 服务器版本相对应的手册,以获取在 'syllabuses Array LEFT JOIN 附近使用的正确语法
oes
。syllabuses
ASSyllabuses
ON (Syllabuses
.`' 在第 1 行
而我的 CakePHP 准备的 SQL 是:
SELECT `Exam`.`id`, `Exam`.`name`, `Syllabuses`.`id`, `Syllabuses`.`name`, `Syllabuses`.`syllabus`, `Syllabuses`.`last_updated`
FROM `oes`.`exams` AS `Exam` syllabuses Array
LEFT JOIN `oes`.`syllabuses` AS `Syllabuses` ON (`Syllabuses`.`exam_id` = `Exam`.`id`)
WHERE 1 = 1 LIMIT 20
但我想要的是类似于下面的查询。我在mysql中测试过:
SELECT `Exam`.`id` AS eid, `Exam`.`name` AS ename, `Syllabuses`.`id` AS sid, `Syllabuses`.`name` AS sname, `Syllabuses`.`syllabus` , `Syllabuses`.`last_updated`
FROM `oes`.`syllabuses` AS `Syllabuses` , exams AS Exam
WHERE Exam.id = Syllabuses.exam_id
ORDER BY Exam.id
LIMIT 20
现在请任何人帮助我实现这一目标。什么样的改变可以让 CakePHP 准备像那样的查询(我尝过的)来完成我的Pagination
工作。
