我尝试在我的项目中使用wbraganca / yii2-dynamicform一切都做得很好，但是当我点击“创建”按钮来验证actionCreate时没有发生任何事情。
项目结构：
供应商（sup_id，sup_name .....）
购买（purchase_id，sup_id，purchase_date）sup_id是外键
purchases_items（purchase_item_id，purchase_id，item_id，qte）purchase_id和item_id是外键
项目（ITEM_ID，......）
我想要做的是当用户创建购买时，他将能够同时创建purchase_items，然后通过使用purchases_items的相应item_id的qte值递增来更新表项中的列库存。
注意：列库存是物料的库存水平。 该项目涉及库存管理。
