如何使用tablegateway加入表格

Question

如何在使用tableadapter時在zend3中加入表格？問題不在於如何在一般情況下連接表，而在於如何在zend中執行此操作，以及在何處放置代碼。

比方說，我HABE例如*表類：

namespace Import\Model; 
use RuntimeException; 
use Zend\Db\TableGateway\TableGatewayInterface; 

class ProjectTable 
{ 
    private $tableGateway='t_project'; 

    public function __construct(TableGatewayInterface $tableGateway) 
    { 
     $this->tableGateway = $tableGateway; 
    } 

public function fetchAll() 
{ 
    return $this->tableGateway->select(); 
} 

我想加入兩個表，我怎麼能做到這一點，北京時間這裏這樣做的正確的地方？我試圖實現以下功能：

public function Project_Unit(Unit $unit = null){ 

    $select = $this->tableGateway->getSql()->select() 
    ->join('t_unit', 't_project.ProjectID = t_unit.ProjectID',array('UnitID','CI_Number', 'Unitname','Shortcut','Suppliername'));  //, left 
    return $this->tableGateway->selectWith($select); 

} 

我沒有得到一個錯誤，我得到了反而混合了數據。之後，我嘗試別名也沒有工作。

我的問題是，如何構建這個表類，如果我需要連接兩個表。這些表格將是項目1 - > n單元（關鍵項目ID）。第二個問題是如何正確使用別名，因爲我在這兩個表中都有一些字段名與不同的數據，例如每個表都有一個列快捷方式。

編輯：新的信息 要查看的數據從何而來，我重新命名Exchangearray的變量：

public function exchangeArray(array $data) 
{ 
    $this->PProjectID= !empty($data['ProjectID']) ? $data['ProjectID'] : null; 
    $this->PCI_Number= !empty($data['CI_Number']) ? $data['CI_Number'] : null; 
    $this->PDescription= !empty($data['Description']) ? $data['Description'] : null; 
    $this->Projectname= !empty($data['Projectname']) ? $data['Projectname'] : null; 
    $this->PShortcut= !empty($data['Shortcut']) ? $data['Shortcut'] : null; 
    $this->PComponent_Class= !empty($data['Component_Class']) ? $data['Component_Class'] : null; 
} 

現在我得到一個有趣的輸出（我加我DataArray中的內容也）

我有兩列被命名爲相同的，那將是快捷和CI-數，這些數據域與來自TableAdapter的表一樣的人混在一起。

U1不是伽利略的快捷方式，它是單位的捷徑。伽利略的捷徑應該是GAL。看起來這些名稱相同的列由第二個表格（單元）填充，但我不會從表格單元獲取任何字段。

編輯：顯示我從jobaer做出來的sugestions的加法：

我編輯ProjectTable類：

class ProjectTable 
{ 
    //private $tableGateway='t_project'; 
    private $projectTableGateway; 
    private $unitTableGateway; 


// public function __construct(TableGatewayInterface $tableGateway) 
// { 
//  $this->tableGateway = $tableGateway; 
// } 

public function __construct(
     TableGatewayInterface $projectTableGateway, 
     TableGatewayInterface $unitTableGateway) 
{ 
    $this->projectTableGateway = $projectTableGateway; 
    $this->unitTableGateway = $unitTableGateway; 
} 


public function fetchAll() 
{ 

    $sqlSelect = $this->unitTableGateway->getSql()->select(); 

    /** 
    * columns for the "project_table" exactly it is unit_table 
    */ 
    $sqlSelect->columns(array('CI_Number', 'ProjectID','Unitname','Shortcut','Suppliername')); 

    /** 
    * this can take two more arguments: 
    * an array of columns for "unit_table" 
    * and a join type, such as "inner" 
    */ 
$sqlSelect->join('t_project', 't_unit.ProjectID = t_project.ProjectID');  


    /** 
    * set condition based on columns 
    */ 
    //$sqlSelect->where(array('unit_table.project_id' => $id)); 

    $resultSet = $this->unitTableGateway->selectWith($sqlSelect); 

    return $resultSet; 



    //return $this->tableGateway->select(); 
} 

我還編輯我Module.php樣的建議，來了一個片段

//      Model\ProjectTable::class => function($container) { 
//       $tableGateway = $container->get(Model\ProjectTableGateway::class); 
//       return new Model\ProjectTable($tableGateway); 
//      }, 
         Model\ProjectTable::class => function($container) { 
          $projectTableGateway = $container->get(Model\ProjectTableGateway::class); 
          $unitTableGateway = $container->get(Model\UnitTableGateway::class); 
          return new Model\ProjectTable($projectTableGateway, $unitTableGateway); 
         }, 

         Model\ProjectTableGateway::class => function ($container) { 
          $dbAdapter = $container->get(AdapterInterface::class); 
          $resultSetPrototype = new ResultSet(); 
          $resultSetPrototype->setArrayObjectPrototype(new Model\Project()); 
          return new TableGateway('t_project', $dbAdapter, null, $resultSetPrototype); 
         } 

我的控制器動作並沒有改變：

return new ViewModel([ 
         'projects' => $this->projectTable->fetchAll(), 
          ]); 

在我看來，我想抓兩個表的列：

foreach ($projects as $project) : 
    // $unit=$units->fetchAllP($project->ProjectID); 
var_dump(get_object_vars($project));?> 
    <tr> 
    <td><?= $this->escapeHtml($project->Unitname) ?></td> 
    <td><?= $this->escapeHtml($project->Projectname) ?></td> 
    <td><?= $this->escapeHtml($project->Shortcut) ?></td> 
    <td><?= $this->escapeHtml($project->CI_Number) ?></td> 
    <td><?= $this->escapeHtml($project->Description) ?></td> 
     <td><?= $this->escapeHtml($project->Component_Class) ?></td> 


     <td> 
      <a href="<?= $this->url('project', ['action' => 'edit', 'id' => $project->ProjectID]) ?>">Edit</a> 
      <a href="<?= $this->url('project', ['action' => 'delete', 'id' => $project->ProjectID]) ?>">Delete</a> 
     </td> 

<?php endforeach; ?> 

我得到了一個有趣的輸出，這樣的東西是人仍下落不明。我希望從兩個連接的表中都有al列。

EDIT2：顯示下一版本

這裏是我的方法使用fetchall（）/班ProjectTable

public function fetchAll() 
    { 

     $sqlSelect = $this->unitTableGateway->getSql()->select(); 
     $sqlSelect->columns(array('UnitID','CI_Number', 'ProjectID','Unitname','Shortcut','Suppliername')); 
     $sqlSelect->join('t_project', 't_unit.ProjectID = t_project.ProjectID', array('Project' =>'Projectname','CI' =>'CI_Number','PDescription' =>'Description','PShortcut' =>'Shortcut','PComponent' =>'Component_Class','PProjectID' =>'ProjectID')); 
     //$sqlSelect->where(array('unit_table.project_id' => $id)); 
     $resultSet = $this->unitTableGateway->selectWith($sqlSelect); 

     //return $resultSet; 
     return $resultSet->toArray(); 

     //return $this->tableGateway->select(); 

這裏是我的viewscript：

<?php 
//var_dump(get_object_vars($projects)); 
foreach ($projects as $project) : 
//var_dump(get_object_vars($project)); 

?> 
    <tr> 
    <td><?= $project['Project']?></td> 
    <td><?= $project['CI']?></td> 
    <td><?= $project['Unitname']?></td> 
    <?php  
endforeach; ?> 

}

，在這裏新的截圖：

EDIT3：加藥裝置的東西

class UnitTable 
{ 
    private $tableGateway='t_unit'; 

    public function __construct(TableGatewayInterface $tableGateway) 
    { 
     $this->tableGateway = $tableGateway; 
    } 

    public function fetchAll() 
    { 
     return $this->tableGateway->select(); 
    } 

類股也：

class Unit implements InputFilterAwareInterface 
{ 
    public $UnitID; 
    public $CI_Number; 
    public $ProjectID; 
    public $Unitname; 
    public $Shortcut; 
    public $Suppliername; 

    private $inputFilter; 

    public function exchangeArray(array $data) 
    { 
     $this->UnitID= !empty($data['UnitID']) ? $data['UnitID'] : null; 
     $this->CI_Number= !empty($data['CI_Number']) ? $data['CI_Number'] : null; 
     $this->ProjectID= !empty($data['ProjectID']) ? $data['ProjectID'] : null; 
     $this->Unitname= !empty($data['Unitname']) ? $data['Unitname'] : null; 
     $this->Shortcut= !empty($data['Shortcut']) ? $data['Shortcut'] : null; 
     $this->Suppliername= !empty($data['Suppliername']) ? $data['Suppliername'] : null; 
    }

Answer 1

如果您知道如何處理模型中的兩個表格，這非常簡單。假設你有ProjectTable和​​模型和兩個TableGateway服務。那些將分別處理數據庫中的兩個表。所以，如果你想加入他們在您的ProjectTable模型，然後將

ProjectTable.php

class ProjectTable 
{ 
    private $projectTableGateway; 
    private $unitTableGateway; 

    public function __construct(
     TableGatewayInterface $projectTableGateway, 
     TableGatewayInterface $unitTableGateway) 
    { 
     $this->projectTableGateway = $projectTableGateway; 
     $this->unitTableGateway = $unitTableGateway; 
    } 

    public function projectUnit($id) 
    { 

     /** 
     * as you are joing with "project_table" 
     * this will handle "unit_table" 
     */ 
     $sqlSelect = $this->unitTableGateway->getSql()->select(); 

     /** 
     * columns for the "unit_table". 
     * if want to use aliases use as 
     * array('alias_name' => 'column_name') 
     */ 
     $sqlSelect->columns(array('column_one', 'column_two')); 

     /** 
     * this can take two more arguments: 
     * an array of columns for "project_table" 
     * and a join type, such as "inner" 
     */ 
     $sqlSelect->join('project_table', 'unit_table.project_id = project_table.id'); 

     /** 
     * set condition based on columns 
     */ 
     $sqlSelect->where(array('unit_table.project_id' => $id)); 

     $resultSet = $this->unitTableGateway->selectWith($sqlSelect); 

     return $resultSet; 
    } 
} 

現在處理兩個表創建兩個TableGateway服務，並將它們傳遞給ProjectTable的構造函數如下

Model\ProjectTable::class => function($container) { 
    $projectTableGateway = $container->get(Model\ProjectTableGateway::class);   
    $unitTableGateway = $container->get(Model\UnitTableGateway::class); 

    return new Model\ProjectTable($projectTableGateway, $unitTableGateway);   
} 

Answer 2

的，我認爲你是缺少點。您不訪問操縱表格網關的表格。你應該做的是使用表網關，這樣你就不必再處理表和SQL了。因此模式的名稱Table Gateway。

看看如何ZF manual describes this。

完成此操作後，很容易在表格網關的單個方法後面連接兩個表格。該方法返回一個完全從數據庫概念中刪除的模型。
