cakephp $ this-> Model-> save（）不更新 [英] cakephp $this->Model->save() not updating

问题描述

这是我的请求 - >数据

  Array 
 
（
 [list] => Array 
（
 [4] > null 
 [2] => null 
 [3] => null 
 [5] => 3 
）
 $ b [ 
  

这是jquery序列化列表中的返回值。键是行id，值是行parent_id。

所以我循环控制器中的数组：

  foreach（$ this-> request-> data ['list'] as $ key => $ value）{
（！isset [$ value]））？ $ orders [$ value] = 0：$ orders [$ value] ++; 
 $ data = array（'id'=> $ key，'parent_id'=>（int）$ value，'display_order'=> $ orders [$ value]）; 
 $ this-> Category-> save（$ data）; 
} 
  

我在循环中创建的$ data数组是正确的，

我已经尝试过各种方式来保存：使用set（）方法，使用$ this-> Category-> id = $ key;而不是直接在数据数组中添加键。

任何想法为什么这不是保存？我确定它是简单的...

解决方案

我认为u忘了保存方法中的蛋糕约定，你有将所有的字段值放在Model名为FirstCap的数组中，类似这样：

  Array 
 
 [ModelName] => Array 
（
 [fieldname1] =>'value'
 [fieldname2] =>'value'
）
）
  

否则你可以使用set为每个值，并且你忘记创建一行对于每一个插入你就这样尝试这样的东西：

  foreach（$ this-> request-> data ['list '] as $ key => $ value）{
（！isset（$ orders [$ value]））？ $ orders [$ value] = 0：$ orders [$ value] ++; 
 $ data = array（'Category'=> array（'id'=> $ key，'parent_id'=>（int）$ value，'display_order'=> $ orders [$ value] ））; 
 $ this-> Category-> save（$ data）; 
} 
  

也可以设置每个id，然后迭代值

  foreach（$ this-> request-> data ['list'] as $ key => $ value）{
（！isset（$ orders [$ value]））？ $ orders [$ value] = 0：$ orders [$ value] ++; 
 $ this-> Category-> id = $ key; 
 $ this-> Category-> set（array（'parent_id'=>（int）$ value，
'display_order'=> $ orders [$ value] 
） ）; 
 
 $ this-> Category-> save（）; 
} 
  

尝试每一个答案，但我认为最后一个会更适合你问题。

I'm trying to build an array and update a few fields in a loop.

This is my request->data

Array

(
    [list] => Array
        (
            [4] => null
            [2] => null
            [3] => null
            [5] => 3
        )

)

It's the return value from a jquery serialized list. The key being the row id and the value being the rows parent_id.

So I loop through the array in the controller:

foreach ($this->request->data['list'] as $key => $value) {
    (!isset($orders[$value])) ? $orders[$value]=0 : $orders[$value]++;
    $data = array('id' => $key, 'parent_id' => (int)$value, 'display_order' => $orders[$value]);
    $this->Category->save($data);
}

The $data array that I create in the loop is correct but the sql logs only shows SELECT COUNT(*) etc. for each row and no UPDATE commands.

I have tried all manner of ways to save this: using set() method, using $this->Category->id = $key; instead of directly adding the key in the data array.

Any ideas why this is not saving? I'm sure it is something simple...

解决方案

i think u forgot the cake convention in the save method, you have to put all the field values inside an array with the Model name FirstCap too, something like this:

Array
(
    [ModelName] => Array
        (
            [fieldname1] => 'value'
            [fieldname2] => 'value'
        )
)

Else you can use set for each and every value, and also youre forgetting to create one row for every insert youre making so try something like this:

foreach ($this->request->data['list'] as $key => $value) {
     (!isset($orders[$value])) ? $orders[$value]=0 : $orders[$value]++;
     $data = array( 'Category' => array('id' => $key, 'parent_id' => (int)$value, 'display_order' => $orders[$value]));
     $this->Category->save($data);
}

Also you can set each and every id and then iterates over the values

foreach ($this->request->data['list'] as $key => $value) {
     (!isset($orders[$value])) ? $orders[$value]=0 : $orders[$value]++;
    $this->Category->id = $key;
    $this->Category->set(array('parent_id' => (int)$value,
                               'display_order' => $orders[$value]
    ));

     $this->Category->save();
}

try each and every answer but i think the last one will fit better at your problem.
