HABTM Paginate排序不起作用?

我在Pagination和蛋糕排序方面遇到了问题。我可以使用第一个表进行排序,但如果我尝试使用第二个表进行排序则不能。

我有以下表格(以及相应的型号): 用户:id,用户名 user_companies:id,user_id,company_id 公司:id,name

所以这很好用:

$this->User->find("all");

Pagiation工作正常:

$this->Paginator->settings = array('sort'=>'User.username');
$this->Paginator->paginate();

但如果我尝试按公司名称排序,我会收到错误:

$this->Paginator->settings = array('sort'=>'Company.name');
$this->Paginator->paginate();
  

错误:SQLSTATE [42S22]:找不到列:1054未知列   'order子句'中的'Company.name'SQL查询:SELECT Userid,   UseremailUserusernameUserpasswordUserrole,   UsercreatedUsermodified FROM cakeblogusers AS User   WHERE 1 = 1 ORDER BY Companyname asc LIMIT 20

为什么这不起作用?

我的用户模型HABTM如下所示:

public $hasAndBelongsToMany = array(
    'Company'=>array(
        'with'=>'UserCompanies'
        )
    );

和公司:

public $hasAndBelongsToMany = array(
    'User' => array(
        'with' => 'UserCompanies',
        )
    );

没有排序的默认查询是:(是,因为tehre实际上是两个查询):

SELECT `User`.`id`, `User`.`email`, `User`.`username`, `User`.`password`, `User`.`role`, `User`.`created`, `User`.`modified` FROM `cakeblog`.`users` AS `User` WHERE 1 = 1 LIMIT 20

查询2:

SELECT `Company`.`id`, `Company`.`name`, `CompaniesUser`.`id`, `CompaniesUser`.`user_id`, `CompaniesUser`.`company_id` FROM `cakeblog`.`companies` AS `Company` JOIN `cakeblog`.`companies_users` AS `CompaniesUser` ON (`CompaniesUser`.`user_id` IN (14, 16, 17) AND `CompaniesUser`.`company_id` = `Company`.`id`)

答案 0 :(得分:0)

我最终创建了两个连接。现在它按预期工作,我可以使用Company.name或任何其他字段进行排序:

    $joins = array();
    $joins[] = array(
        'table'=>'companies_users',
        'alias'=>'CompanyUser',
        'type'=>'LEFT',
        'conditions'=>array(
            'CompanyUser.user_id = User.id'
            )
        );

    $joins[] = array(
        'table'=>'companies',
        'alias'=>'Company',
        'type'=>'LEFT',
        'conditions'=>array(
            'CompanyUser.company_id = Company.id')
        );

    $this->Paginator->settings = array('sort'=>'Company.name', 'joins'=>$joins);
    $x = $this->paginate();
    debug($x);
