【问题描述】：

我这里有一个梨形的。它把我逼疯了，花了一天的时间在上面。我希望有人可以快速浏览一下并指出明显的内容。

我几乎完成了从 1.3.14 到 2.4.2 的 cakephp 升级。我遇到的其余问题之一是 saveAll 模型调用......它实际上是正确插入第一个数组的数据，但其余部分抛出异常。

我得到的错误是：

Error: Cannot use string offset as an array 
File: /srv/www/test/public_html/app/Lib/cakephp/lib/Cake/Model/Model.php    
Line: 2453

如果我查看 Model.php，问题就出现在这里：

        case 'hasMany':
            foreach ($values as $i => $value) 

                if (isset($values[$i][$association])) 
                    $values[$i][$association][$key] = $this->id;
                 else                         
                    $values[$i] = array_merge(array($key => $this->id), $value, array($key => $this->id));
                
            

$values[$i][$association][$key] = $this->id;

我在这里转储了输出，本例 $values[$i][$association] = 3，它不是数组。

现在，查看发布的数据，我看不出有什么问题。和 cake1.3.14 一样。

发布数据的 var_dump：

array(3) 
  ["Client"]=>
  array(20) 
    ["NAME"]=>
    string(6) "ZZTEST"
    ["PHONE"]=>
    string(0) ""
    ["X_PHONE2"]=>
    string(0) ""
    ["FAX"]=>
    string(0) ""
    ["EMAIL"]=>
    string(0) ""
    ["X_REQUIRE_PO"]=>
    string(1) "N"
    ["TAXREG"]=>
    string(0) ""
    ["CREDLIMIT"]=>
    string(5) "10000"
    ["X_QCHECKAPP"]=>
    string(1) "Y"
    ["X_PUBLIC_LIABILITY_EXPIRY"]=>
    string(10) "19-03-2014"
    ["ADDRESS1"]=>
    string(0) ""
    ["ADDRESS2"]=>
    string(0) ""
    ["POST_CODE"]=>
    string(0) ""
    ["DELADDR1"]=>
    string(0) ""
    ["DELADDR2"]=>
    string(0) ""
    ["DELADDR6"]=>
    string(0) ""
    ["NOTES"]=>
    string(0) ""
    ["HEAD_ACCNO"]=>
    int(-1)
    ["CURRENCYNO"]=>
    int(0)
    ["AVE_DAYS_TO_PAY"]=>
    int(-1)
  
  ["ClientRateGroup"]=>
  array(1) 
    ["rate_group_id"]=>
    string(1) "3"
  
  ["ClientExtra"]=>
  array(2) 
    ["client_type_id"]=>
    string(1) "1"
    ["client_salesperson_id"]=>
    string(2) "25"
  

控制器的一个sn-p：

class ClientsController extends AppController

public $name = 'Clients';
public $uses = array('ExonetClient', 'Quote');

// The saveAll call is causing the problem
function add()


    if (!empty($this->request->data)) 
        $this->request->data['ExonetClient']['HEAD_ACCNO']      = -1;
        $this->request->data['ExonetClient']['CURRENCYNO']      = 0;
        $this->request->data['ExonetClient']['AVE_DAYS_TO_PAY'] = -1;
        $this->Client->create();
        unset($this->ExonetClient->ClientRateGroup->validate['client_id']);
        unset($this->ExonetClient->ClientExtra->validate['client_id']);

        // Allow an entry to clients_rate_groups table if the rate group is
        //selected for a client
        if (!empty($this->request->data['ClientRateGroup']['rate_group_id'])
            || !empty($this->request->data['ClientExtra']['client_type_id'])
        ) 

            if ($this->ExonetClient->saveAll($this->request->data, array('validate' => true)) === true) 
                //
                // If an AJAX request, then echo the ID of the item.
                if ($this->RequestHandler->isAjax()) 
                    echo $this->ExonetClient->getLastInsertId();
                    exit;
                
                else 
                    $this->Session->setFlash(
                        __('The client has been saved successfully'),
                        'default',
                        array('class' => 'success')
                    );

                    $this->redirect(array('action' => 'index'));
                
            
            else 
                $error = __('The client could not be saved. Please, try again.');
                if ($this->RequestHandler->isAjax()) 
                    $this->set('error_message', $error);
                
                else 
                    $this->Session->setFlash($error);

【问题讨论】：

请注意，您的错误消息中的行号与您在 2.4.2 中显示的型号代码不匹配

我在里面有一些调试语句，一定是把行号弄错了。绝对是 2.4.2 代码库

【参考方案1】：

您的数据格式不正确，无法保存hasMany 关联数据。检查docs for Model::saveAssociated()：

为了保存一条记录及其具有hasMany关联的相关记录，数据数组应该是这样的：

$data = array(
    'Article' => array('title' => 'My first article'),
    'Comment' => array(
        array('body' => 'Comment 1', 'user_id' => 1),
        array('body' => 'Comment 2', 'user_id' => 12),
        array('body' => 'Comment 3', 'user_id' => 40),
    ),
);

所以你的ClientRateGroup 键应该包含一个数据数组的数组，类似于：

'ClientRateGroup' => array(
    array('rate_group_id' => 3)
)

也许你的ClientExtra 数据也应该这样格式化，不确定Client 模型上没有适当的关联，很可能这实际上应该是Client hasOne ClientExtra 关联，很难说。

【讨论】：

自蛋糕 1.3.14 以来这是否发生了变化？我将尝试按照 saveAssociated 文档重新格式化请求。

@AdamP 我不确定，现在无法测试，但 1.3 的书提倡相同的风格：book.cakephp.org/1.3/en/The-Manual/Developing-with-CakePHP/…
