在symfony循環中使用外鍵

Question

我有三個表。兩個使用一個外鍵來提取數據，一個顯示數據。

我的表是這樣的：

department: 
id: 1 name: illustration 
id: 2 name photography 
etc... 

type: 
id: 1 name: ink 
id: 2 name: charcoal 
etc... 

user: 
id: 1 firstname: Fred lastname: Flintstone 
id: 2 firstname: Barney lastname: Rubble 
etc.... 

所以我想根據部門與該行的類型和用戶數據的順序來顯示數據。

例如：

Illustration 
ink  Fred Flintstone 
charcoal Fred Flintstone 
painting Fred Flintstone 

Photography 
ink  Barney Rubble 
painting Barney Rubble 

我至今的作品，但我認爲它可以執行好得多。這是whatI有工作：

應用/前端/模塊/富/動作/的actions.class.php

public function executeIndex(sfWebRequest $request) 
    { 
    $this->illustration = Doctrine_Core::getTable('User') 
     ->createQuery('a') 
     ->where('a.department_id = 1') 
     ->execute(); 

    $this->photography = Doctrine_Core::getTable('User') 
     ->createQuery('a') 
     ->where('a.department_id = 2') 
     ->execute(); 
} 

和索引 應用/前端/模塊/富/模板/ indexSuccess。 PHP

<?php foreach ($illustration as $user): ?> 
     <tr> 
     <td class="displayDept" valign="top"><?php echo $user->getDepartment() ?></td> 
    </tr> 
    <tr> 
    <?php foreach ($illustration as $user): ?> 
    <tr> 
     <td class="displayInfo" valign="top"><?php echo $user->getType() ?></td> 
     <td class="displayInfo" valign="top"><?php echo $user->getUrl() ?></td> 
     <td class="displayInfo" valign="top"><?php echo simple_format_text($user->getDescription()) ?></td> 
     <td class="displayInfo" valign="top"><?php echo $user->getDateTimeObject('created_at')->format('m/d/Y') ?></td> 
    </tr> 
    <?php endforeach; ?> 

    <?php endforeach; ?> 
    <tr> 
    <?php foreach ($photography as $me): ?> 
    <tr> 
     <td class="displayDept" valign="top"><?php echo $me->getDepartment() ?></td> 
    </tr> 
    <?php foreach ($photography as $me): ?> 
    <tr> 
     <td class="displayInfo" valign="top"><?php echo $me->getType() ?></td> 
     <td class="displayInfo" valign="top"><?php echo $me->getUrl() ?></td> 
     <td class="displayInfo" valign="top"><?php echo simple_format_text($me->getDescription()) ?></td> 
     <td class="displayInfo" valign="top"><?php echo $me->getDateTimeObject('created_at')->format('m/d/Y') ?></td> 
    </tr> 
    <?php endforeach; ?> 
    <?php endforeach; ?> 

現在，這個工作，但如果部門列表變得很長的什麼樣。這意味着我必須在操作中創建一個新的數據庫查詢，並在indexSuccess.php文件中使用foreach選項。

是否有辦法在行中的後續數據上使用WHERE選項來提取所有部門數據？

UPDATE

這裏是架構，我認爲這是非常接近到什麼@ManseUK建議：

Department: 
actAs: { Timestampable: ~ } 
columns: 
    id: { type: integer(4), primary: true, autoincrement: true } 
    name: { type: string(255), notnull: true, unique: true } 

Type: 
actAs: { Timestampable: ~ } 
columns: 
    id: { type: integer(4), primary: true, autoincrement: true } 
    name: { type: string(255), notnull: true, unique: true } 
    user_id: { type: integer(4) } 

User: 
actAs: { Timestampable: ~ } 
columns: 
    id: { type: integer(4), primary: true, autoincrement: true } 
    firstname: { type: string(255), notnull: true } 
    lastname: { type: string(255), notnull: true } 
    email: { type: string(255), notnull: true, unique: true } 
    department_id: { type: integer(4), notnull: true } 
    type_id: { type: integer(4), notnull: true } 
    url: { type: string(255), notnull:true } 
    description: { type: string(4000) } 
relations: 
    Department: { class: Department, local: department_id, foreign: id } 
    Type: { class: Type, local: type_id, foreign: id, foreignAlias: Users } 

Answer 1

沒有看到你的schema.yml其很難說 - 但如果你有在模式中正確設置別名，那麼你應該可以做類似的事情：

actions.php

public function executeIndex(sfWebRequest $request) 
{ 
    $this->departments = Doctrine_Core::getTable('departments') 
     ->findAll(); 
    // returns all departments or you could change this to just select departments by name/id 
} 

indexSuccess.php的

<?php foreach ($departments as $dept): ?> 
     <tr> 
     <td class="displayDept" valign="top"><?php echo $dept->getName() ?></td> 
    </tr> 
    <tr> 
    <?php foreach ($dept->getUsers() as $user): ?> 
    <tr> 
     <td class="displayInfo" valign="top"><?php echo $user->getType() ?></td> 
     <td class="displayInfo" valign="top"><?php echo $user->getUrl() ?></td> 
     <td class="displayInfo" valign="top"><?php echo simple_format_text($user->getDescription()) ?></td> 
     <td class="displayInfo" valign="top"><?php echo $user->getDateTimeObject('created_at')->format('m/d/Y') ?></td> 
    </tr> 
    <?php endforeach; ?> 
    <?php endforeach; ?> 

的schema.yml

Department: 
    columns: 
    id: 
     type: integer 
     primary: true 
     autoincrement: true 
    name: String(25) 
Type: 
    columns: 
    id: 
     type: integer 
     primary: true 
     autoincrement: true 
    name: String(25) 
User: 
    columns: 
    id: 
     type: integer 
     primary: true 
     autoincrement: true 
    firstname: string(25) 
    lastname: string(25) 
    department: integer 
    type: integer 
    relations: 
     Department: 
     class: Department 
     local: department 
     foreign: id 
     foreignAlias: Users 
     Type: 
     class: Type 
     local: type 
     foreign: id 
     foreignAlias: Users 

的foreignAlias參數是這裏的關鍵 - 它的細節表之間的關係的名字 - 讓你打電話$dept->getUsers() - 返回所有用戶對於特定部門
