【问题描述】：
尝试使用 yii2-dynamicform 创建动态表单时出错。在创建方法时它工作正常，但在更新时显示错误。我有两张桌子一张是 1.供应商& 2.vendors_more_categories
供应商和供应商_more_categories 之间的关系是 1-* 我刚刚推荐了 https://github.com/wbraganca/yii2-dynamicform 这个链接。

【问题讨论】：
-
name
modelsVendorsMoreCategories有一些拼写错误。检查相应的操作。 -
您好，谢谢您的回复，您可以检查我的代码吗，我没有得到您的答案。
-
渲染_form文件时是否传递
$modelsVendorsMoreCategories变量？ -
我将其渲染为 - return $this->render('update', [ 'model' => $model, 'modelsVendorsMoreCategories' => (empty($modelsVendorsMoreCategories)) ? [new VendorsMoreCategories ] : $modelsVendorsMoreCategories ]);
