好吧我正在尝试我的第一个saveAll(或saveMany或saveAssociated不确定哪个是“正确”),其中包含hasMany关系,我似乎无法弄清楚蛋糕是如何想要这些数据的。我可以在主表上获取名称字段进行更新,但我无法获得更新的hasMany关系。
我只是想朝着正确的方向前进,我不顾一切地学习,但想到用我的头在墙上钻一个洞看起来越来越诱人。
只是一点背景我有两个表“供应商”表和“vendor_payment_types”表。 “供应商”表中有很多“vendor_payment_types。结构如下:
供应商表 id,company_id,name
vendor_payment_types id,vendor_id,type
目前我发送给控制器的数组是(如果支付类型有一个id,表示它已经存在于数据库中,不需要发生任何事情,如果没有id需要添加,第三部分是如果它存在于数据库中但不存在于此数组中,则需要从数据库中删除它:
Array
(
[0] => Array
(
[Vendor] => Array
(
[id] => 7
[company_id] => 2
[name] => Test Vendor
[VendorPaymentTypes] => Array
(
[0] => Array
(
[vendor_id] => 7
[id] => 13
[type] => payable
)
[1] => Array
(
[vendor_id] => 7
[type] => check
)
[2] => Array
(
[vendor_id] => 7
[id] => 14
[type] => cash
)
)
)
)
我需要做的是a)更新名称b)添加任何新的VendorTypes c)删除不在POST数组中但存在于数据库中的任何VendorTypes。以下是我在VendorController中的内容:
public function save() {
$vendors = array();
$companyid = $this->Auth->user('company_id');
$needle = 'new';
$i = 0;
// Setup array and also if id of payment_type includes "new" unset the id so cake will add a new and not try and match id and update
if ($this->request->is('post')) {
foreach ($this->request->data['Vendor'] as $vendorId => $vendor) {
$vendors[$vendorId]['Vendor']['id'] = $vendorId;
$vendors[$vendorId]['Vendor']['company_id'] = $companyid;
$vendors[$vendorId]['Vendor']['name'] = $vendor['name'];
foreach ($vendor['VendorTypes'] as $type => $val) {
if ($val != '0') {
$vendors[$vendorId]['Vendor']['VendorPaymentTypes'][$i]['vendor_id'] = $vendorId;
$vendors[$vendorId]['Vendor']['VendorPaymentTypes'][$i]['id'] = $val;
$vendors[$vendorId]['Vendor']['VendorPaymentTypes'][$i]['type'] = $type;
if (strstr($vendors[$vendorId]['Vendor']['VendorPaymentTypes'][$i]['id'], $needle)) {
unset($vendors[$vendorId]['Vendor']['VendorPaymentTypes'][$i]['id']);
}
$i++;
}
}
}
// Clean up array to make it an array starting at 0 and not based on vendor['id']
$cleanedarr = array();
foreach ($vendors as $vendor => $data) {
$cleanedarr[] = $data;
}
// Currently this only updates the name
if ($this->Vendor->saveAll($cleanedarr, array('deep' => TRUE) )) {
$this->Session->setFlash('Updated Vendors!');
die(pr($this->Vendor->getDataSource()->getLog()));
} else {
$this->Session->setFlash('Failed to Update');
}
}
}
供应商模型设置为
public $name = 'Vendor';
public $hasMany = array(
'VendorPaymentTypes' => array(
'className' => 'VendorPaymentTypes',
'foreignKey' => 'vendor_id',
'dependent' => true
)
);
我甚至没有开始解决删除部分,因为我无法添加新的vendor_types。在无数的“尝试”中度过了美好的一天,所有的一切都没有发现。
感谢您一百万次的帮助!
答案 0 :(得分:0)
关联日期(供应商类型)不应该是供应商数据中的数组,而应该是外部数据。
array(
'Vendor' =>
array('name' => 'test', 'id' => 7),
'VendorPaymentType => array(
array('id' => 13, 'type' => 'payable'),
array('type' => 'check')
)
);
因此VendorPaymentType不是供应商数据的一部分。为了进一步混淆你,更深层次的关联应该是'父'数组的一部分。
另外:
希望这会有所帮助。 : - )
