yii2动态表单仅更新一个表

我正试图在yii2/动态表单的帮助下更新数据。 表1-“销售”列（ssg_id、ssg_客户、ssg_发票编号、ssg_日期、ssg_金额） 表2-“销售项目SG”-列（ssgi\u id、ssgi\u发票编号、ssgi\u sgname、ssgi\u价格）

关系-sellsg.ssg_invoiceno=sellitemsg.ssgi_invoiceno

“创建”部分工作正常。我正在努力更新部分。 问题1。 当表单创建新记录时，表单中有一个javascript代码，每次都将发票号增加1。当我加载表单进行更新时，它也会增加1，覆盖原始的invoiceno。我只想在创建时限制此函数，但不想在更新时限制此函数

问题2 当我更新表单时，它只更新sellsg表，而不更新sellitemsg表

_形式

sellsg模型

<?php

namespace frontend\modules\sellsg\models;

use Yii;

/**
 * This is the model class for table "sellsg".
 *
 * @property integer $ssg_id
 * @property string $ssg_customer
 * @property integer $ssg_invoiceno
 * @property string $ssg_date
 * @property integer $ssg_amount
 */
class Sellsg extends \yii\db\ActiveRecord
{
    public $modelsSellitemsg;
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'sellsg';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['ssg_customer', 'ssg_invoiceno', 'ssg_date', 'ssg_amount'], 'required'],
            [['ssg_invoiceno', 'ssg_amount'], 'integer'],
            [['ssg_customer'], 'string', 'max' => 200],
            [['ssg_invoiceno'], 'unique'],
            [['ssg_date'], 'string', 'max' => 10], 
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'ssg_id' => 'ID',
            'ssg_customer' => 'Customer',
            'ssg_invoiceno' => 'Invoice No',
            'ssg_date' => 'Date',
            'ssg_amount' => 'Amount',
        ];
    }
    public function getSellitemsg()
        {
            return $this->hasMany(Sellitemsg::className(), ['ssgi_invoiceno' => 'ssg_invoiceno']);
        }
}

我找到了解决办法

问题1- 我已经创建了

\u updateform.php

，并从那里重定向到更新，删除了加载invoicno的javascript- Update.php

<?php

use yii\helpers\Html;

/* @var $this yii\web\View */
/* @var $model frontend\modules\sellsg\models\Sellsg */

$this->title = 'Update InvoiceNo: ' . $model->ssg_id;
$this->params['breadcrumbs'][] = ['label' => 'Sellsgs', 'url' => ['index']];
$this->params['breadcrumbs'][] = ['label' => $model->ssg_id, 'url' => ['view', 'id' => $model->ssg_id]];
$this->params['breadcrumbs'][] = 'Update';
?>
<div class="sellsg-update">

    <h1><?= Html::encode($this->title) ?></h1>

    <?= $this->render('_updateform', [
        'model' => $model,
        'modelsSellitemsg' => $modelsSellitemsg,
    ]) ?>

</div>

和Model.php-

<?php

namespace frontend\modules\sellsg\models;

use Yii;
use yii\helpers\ArrayHelper;

class Model extends \yii\base\Model
{
    /**
     * Creates and populates a set of models.
     *
     * @param string $modelClass
     * @param array $multipleModels
     * @return array
     */
    public static function createMultiple($modelClass, $multipleModels = [])
    {
        $model    = new $modelClass;
        $formName = $model->formName();
        $post     = Yii::$app->request->post($formName);
        $models   = [];

        if (! empty($multipleModels)) {
            $keys = array_keys(ArrayHelper::map($multipleModels, 'ssgi_id', 'ssgi_id'));
            $multipleModels = array_combine($keys, $multipleModels);
        }

        if ($post && is_array($post)) {
            foreach ($post as $i => $item) {
                if (isset($item['ssgi_id']) && !empty($item['ssgi_id']) && isset($multipleModels[$item['ssgi_id']])) {
                    $models[] = $multipleModels[$item['ssgi_id']];
                } else {
                    $models[] = new $modelClass;
                }
            }
        }

        unset($model, $formName, $post);

        return $models;

也许我们应该使用一些通信服务（比如电子邮件或类似的服务），因为您最近发布了很多问题，而且大多数问题可能还没有解决。许多问题已经解决。没有几个悬而未决。我是这个领域的初学者。有很多问题。不过我喜欢这项服务。周围有很多乐于助人的人。我明白了，我的错，我以为没有一个人得到解决。嗯，我现在没有时间，但我明天可能会看一看。也许我们应该使用一些通讯服务（比如电子邮件或类似的服务），因为你最近发布了很多问题，很可能大部分问题还没有解决。很多问题已经解决了。没有几个悬而未决。我是这个领域的初学者。有很多问题。不过我喜欢这项服务。周围有很多乐于助人的人。我明白了，我的错，我以为没有一个人得到解决。嗯，我现在没有时间，但我明天可能会去看看。
