Php 集合类型实体问题

我正在尝试创建一个可以处理多个文件上传的表单。到现在为止，一直都还不错。我有两个表，图像和产品有很多关系。我正在为图像使用CollectOnType字段，以便动态添加/删除字段。问题是我在表单呈现时遇到了这个异常

Neither the property "imageFile" nor one of the methods "getImageFile()", "imageFile()", "isImageFile()", "hasImageFile()", "__get()" exist and have public access in class "AppBundle\Entity\Product".

我做错了什么

首先： 在您的

产品类别中

：

您的变量名为

private$image

，它应该是

private$images

；用“S”表示复数

秒：

在产品表单生成器中，您需要一个名为

ImageFile

的字段，但它不存在于

product class

中（但存在于

Image class

），它应该是

images
