我创建MainBlogBundle Category.php
Product.php
和通过PHP应用程序/控制台命令使用YML映射注解用。使用CRUD操作进行添加/编辑/删除/表演动作后,我尝试添加一个类别,并提交Add category form
后,我得到了警告:spl_object_hash()预计参数1是对象
Warning: spl_object_hash() expects parameter 1 to be object, string given in
/var/www/sitetwo/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php line 1367
我张贴在GitHub上我的示例代码以下是数据库的脚本。

请问你能解释一下当你抛出异常时你到底想做什么吗?清除缓存? – nifr
顺便说一句,只是看着你的个人资料中提供的[个人主页](http://veerpartap.com/),发现有一点“错误”。正确的术语是软件**工程师**而不是工程师*或者是我不懂的某种文字游戏? :) – nifr
感谢您的信息并纠正错字错误。 关于这个问题,我发现我必须在类别控制器中包含ArrayCollection类。一旦我添加该行,我看到另一个错误,在产品部分 “__toString()”方法找不到在类型“Main \ BlogBundle \ Entity \ Category”传递给选择字段的对象。要改为读取自定义getter,请将选项“属性”设置为所需的属性路径。 “ –
