一次保存多个关联的实体Cakephp

Question

我已经订购了一个订单，但是每个订单的多个订单（产品和总价格，数量）并不与订单一起保存。

这是现阶段的日志转储：

{ "associated": [ "Orderlines", "Payments" ], "Orderlines": [ { "total_cost": "222.44", "total_quantity": "2", "product_variants_id": "34" }, { "total_cost": "154", "total_quantity": "2", "product_variants_id": "33" } ], "users_id": 1, "usersaddress_id": 1, "orderstatus": 0, "date": "2017-09-21T01:53:38+00:00", "last_modified": "2017-09-21T01:53:38+00:00" } 

控制器：

$associated = ['Orderlines', 'Payments']; 
    $order = $this->Orders->newEntity(['associated'=>$associated]); 
    if ($this->request->is('post')) { 
     $order = $this->Orders->patchEntity($order, $this->request->getData()); 
     $order->users_id = $this->Auth->user('id'); 
     //Hardcoded the SHU MART stores location because thats all thats gonna get implemented for now 
     $order->usersaddress_id = 1; 
     $order->orderstatus = 0; 
     $order->date = Time::now(); 
     $order->last_modified = Time::now(); 

     //god this is ugly. forgive me for i have sinned 
     $order->setDirty('users_id', true); 
     $order->setDirty('usersaddress_id', true); 
     $order->setDirty('date', true); 
     $order->setDirty('last_modified', true); 
     $order->setDirty('orderlines', true); 
     if ($this->Orders->save($order)) { 

      $this->Flash->success(__('The order has been saved.')); 

      return $this->redirect(['controller'=>'orderlines','action' => 'index']); 

     } 
     $this->Flash->error(__('The order could not be saved. Please, try again.')); 
    } 

和订单项目循环内形式：

<?php 
        echo $this->Form->control('Orderlines.'.$orderLineIndex.'.total_cost', 
         ['label'=>'', 'value'=>$product_total 
          , 'type'=>'hidden' 
         ]); 
        ?> 
        <?php 
        echo $this->Form->control('Orderlines.'.$orderLineIndex.'.total_quantity', 
         ['label'=>'', 'value'=>$item['quantity'] 
          , 'type'=>'hidden' 
         ]); 
        ?> 
        <?php 
        echo $this->Form->control('Orderlines.'.$orderLineIndex.'.product_variants_id', 
         ['label'=>'', 'value'=>$item['id'] 
          , 'type'=>'hidden' 
         ]); 
        ?> 

现在我已经试过了没有Orderlines.在开始，并试图单独保存每个订单，但它不会保存订单我d和东西。

我只是想能够一次性保存它。例如：

order{ id, x, y, orderlines[[0]{OL1...}[1]{OL2}] } 

因此，我可以在订单中包含尽可能多的订单并将它们全部保存在一起。我想我只是缺少一个小的语法，但也许我不是。

Answer 1

所以我有2个答案。第一个是真正的杂乱无章的解决方案，以及我后来发现的解决方案。

if ($result) { 
     $orderlinescontroller = new OrderlinesController(); 
     if ($orderlinescontroller->addAllFromCart($result->id)) { 

      $this->Flash->success(__('The order ' . $result->id . ' has been successfully placed')); 
      $this->clearUsersCart($this->Auth->user('id')); 

所以先保存订单，然后创建一个需要保存多个关联项的控制器实例。然后，我创建了一个函数，查看购物车项目的db/session变量以将它们保存在订单中。

public function addAllFromCart($order_id) 
    { 
     $success = true; 
     $cart_items = $this->getCartItemsArray(); 
     $saved_ids = []; 
     foreach ($cart_items as $cart) { 
      $this->log($cart); 
      $orderline = $this->makeEntity($order_id, $cart); 
      $new = $this->Orderlines->save($orderline); 
      if ($new) { 
       $this->log('Line saved'); 
       array_push($saved_ids, $new->id); 
      } else { 
       $this->log('Line save FAILED'); 
       $success = false; 

       //if there is a failure, we need to delete the lines that we made - there is a better way, but cake sucks and conventions don't work 
       foreach ($saved_ids as $id_to_delete) { 
        $d = $this->Orderlines->get($id_to_delete); 
        $this->Orderlines->delete($d); 
       } 

      } 
     } 
     $this->log('WAS ADD ALL FROM CART A SUCCESS? -- ' . $success); 
//  if ($success) { 
//   return $this->redirect($this->referer()); 
//  } else { 
//   return $this->redirect($this->referer()); 
//  } 

     return $success; 
    } 
` 

这完全是超级混乱和un-cake-ey，但它的工作原理。另一种解决方案是当我重新访问添加产品的一部分时发现的，它是如何明确告诉save（）要保存什么关联的。因此使用了下面的内容。

$result = $this->Orders->save($save, ['associated' => ['Orderlines']]);
