Question

从doctrine pager对象检索数据时，我遇到了一些问题！让我在下面描述一下：

这是我的寻呼机查询：

        $pager = new sfDoctrinePager('sfGuardUser', '5'); 

        $q = Doctrine_Query::create()
                        ->select('u.id, u.username,  p.org_name,  g.name, l.status')
                        ->from('sfGuardUser u')
                        ->leftJoin('u.Profile p')
                        ->leftJoin('u.Groups g')
                        ->leftJoin('u.LicensedVendors l')
                        ->where('g.name = \'client\'');

        $pager->setQuery($q);
        $pager->setPage($request->getParameter('page', 1));
        $pager->init();

现在在我的模板中，我可以检索我的sfGuardUser和Profile数据，如下所示：

 foreach ($pager->getResults() as $data) {


            echo $data->username ;  //outputs 'username' from sfGuardUser table
            echo '<br />' ;
            echo $data->Profile->org_name ; //outputs 'Organization name' from sfGuardUserProfile table 

}

但我仍无法检索群组＆amp;使用$data->Groups->name或$data->LicensedVendors->status的 LicensedVendors 数据！它也没有显示任何错误或任何值！看起来它输出一个空字符串。它不应该像Profile数据一样获得价值吗？

但是，当hydrate通过设置$q->setHydrationMode(Doctrine_Core::HYDRATE_SCALAR);查询时：

foreach ($pager->getResults() as $data) { echo $data['u_username']; echo $data['p_org_name']; echo $data['g_name']; echo $data['l_status']; }

我可以通过以下方式检索所有数据：

**Doctrine_Core::HYDRATE_SCALAR**

如何在不设置License: actAs: [Timestampable] tableName: licenses columns: id: type: integer(4) primary: true notnull: true autoincrement: true status: type: enum values: ['approved','pending_admin','pending_client','pending_vendor','rejected'] default: 'pending' client_id: type: integer(8) notnull: true vendor_id: type: integer(8) notnull: true product_desc: type: clob(16777215) supplier_name: type: string(80) other_desc: type: string(50) financial_statement: type: clob relations: ClientUser: class: sfGuardUser local: client_id foreign: id foreignAlias: LicensedVendors onDelete: cascade foreignType: many owningSide: true VendorUser: class: sfGuardUser local: vendor_id foreign: id foreignAlias: LicensedClients onDelete: cascade foreignType: many owningSide: true sfGuardUser: actAs: [Timestampable] columns: first_name: string(255) last_name: string(255) email_address: type: string(255) notnull: true unique: true username: type: string(128) notnull: true unique: true algorithm: type: string(128) default: sha1 notnull: true salt: string(128) password: string(128) is_active: type: boolean default: 1 is_super_admin: type: boolean default: false last_login: type: timestamp indexes: is_active_idx: fields: [is_active] relations: Groups: class: sfGuardGroup local: user_id foreign: group_id refClass: sfGuardUserGroup foreignAlias: Users sfGuardUserProfile: actAs: Timestampable: ~ columns: user_id: type: integer notnull: true email: type: string(80) notnull: true unique: true email_new: type: string(80) unique: true firstname: type: string(30) lastname: type: string(70) org_name: type: string(80) notnull: true relations: User: class: sfGuardUser foreign: id local: user_id type: one onDelete: cascade foreignType: one foreignAlias: Profile sfGuardGroup: actAs: [Timestampable] columns: name: type: string(255) unique: true description: string(1000) relations: Users: class: sfGuardUser refClass: sfGuardUserGroup local: group_id foreign: user_id foreignAlias: Groups的情况下获取这些数据？在将组和许可表数据作为对象检索时，我做错了吗？

您可以尝试使用ArrayAccess。

含义

 foreach ($pager->getResults() as $data) {


        echo $data['username'] ;  //outputs 'username' from sfGuardUser table
        echo '<br />' ;
        echo $data['Profile'][0]['org_name'] ; //outputs 'Organization name' from sfGuardUserProfile table

或许问题是代码中缺少[0]，意思是

 echo $data->Profile[0]->org_name ; //outputs 'Organization name' from sfGuardUserProfile table

从sfDoctrinePager对象中检索doctrine数据！
