不是访问modelsVendorsMoreCategories [0]（作为数组的一个元素）
'model'=> $modelsVendorsMoreCategories[0],
在DinamicForm组件，但是当你更新你的模型通过为$ modelsVendorsMoreCategories这个值
$modelsVendorsMoreCategories = $model->ven_id;
（不似是一个数组，你必须确保这个对象包含在0指数与适当的元素的数组））
'modelsVendorsMoreCategories' => (empty($modelsVendorsMoreCategories)) ?
[new VendorsMoreCategories] : $modelsVendorsMoreCategories
]);

$ modelsVendorsMoreCategories应包含actionUpdate方法VendorsMoreCategories模型。在此代码（$ modelsVendorsMoreCategories = $模型 - > ven_id）$ modelsVendorsMoreCategories包含$模型 - > ven_id。它是一个整数值，而不是VendorsMoreCategories对象。
卖方模式应该包含在VendorsMoreCategories模型的关系：
class Vendors extends \yii\db\ActiveRecord
{
....
public function getVendorsMoreCategories()
{
return $this->hasMany(VendorsMoreCategories::className(), 'vendor_id'=>'id']);
}
}
然后，你应该用你的actionUpdate方法的关系：
$model = $this->findModel($id);
$modelsVendorsMoreCategories = $model->vendorsMoreCategories;
if(!$modelsVendorsMoreCategories) {
$modelsVendorsMoreCategories = [new VendorsMoreCategories];
}

在你actionUpdate您有：
$modelsVendorsMoreCategories = $model->ven_id;
但是，你应该有：
$modelsVendorsMoreCategories = $model->nameOfMyRelation;
为了得到什么是真正的名字，走在你的$模式，并期待这样的事情：
/**
* @return \yii\db\ActiveQuery
*/
public function getNameOfMyRelation()
{
return $this->hasMany(VendorsMoreCategories::className(), ['ven_id' => 'id']);
}
如果你没有使这两个表之间的关系的任何功能，写一个。如果您有问题这样做，你可以随时使用gii的模型生成和检查卖方模型（你不需要更换，只是预览代码）。

检查create.php文件视图文件夹，从这里_form.php这个文件传递所需的变量为： -
<?= $this->render('_form', [
'model' => $model,
'modelsAddress' => $modelsAddress,
]) ?>

检查您创建针对文件夹中的文件：
控制器：控制器传递参数到create.php
return $this->render('create', [
'model' => $model,
'modelsVendorsMoreCategories' => (empty($modelsVendorsMoreCategories)) ? [new VendorsMoreCategories] : $modelsVendorsMoreCategories
]);
查看：create.php
如果你错过了一个参数： 'modelsVendorsMoreCategories'=> $ modelsVendorsMoreCategories。它显示在页面_form.php这个未定义变量错误。
<?= $this->render('_form', [
'model' => $model,
'modelsVendorsMoreCategories' =>$modelsVendorsMoreCategories
])?>
查看：_form.php这个
$modelsVendorsMoreCategories[0];
前现在它传递参数不及格。
