我在尝试将实体放入Sonata Admin Bundle时遇到问题。我有大约5个实体，它们在捆绑包中被精细地列出和查看，但我无法编辑或创建新条目。
当我尝试编辑或创建时，我会得到一个ReflectionException错误：
类不存在
为了解决这个问题，我尝试在命名空间上操作（将控制器移动到与Admin文件相同的命名空间中，等等），或者调整Admin controller，以便告诉它我的实体（"->add（'individual'，'entity'，array（'class'=>'Platform''ProjectBundle''entity''individual'）"而不是->add（'individual'））。
我的实体名为Biosample。这是实体文件：

这个错误的原因是教程中的错误复制/粘贴。
在Admin类中，函数configureFormFields包含一个描述不正确的字段"Description"。
->with('Description')
->add('description', 'sonata_type_model', array('multiple' => false))
->end()
我不得不将其替换为：
->with('Description')
->add('description')
->end()
我发现自动生成Admin Class骨架是Sonata Admin Bundle的一个功能。为了自动生成，执行：
php应用程序/控制台sonata:admin：生成
然后输入实体的完整路径，在本例中为：
平台''项目包''实体''生物样本
管理捆绑包将解析您的实体和：
- 生成管理类文件
- 在应用程序捆绑包的service.yml中添加一个条目
- 为CRUD控制器生成选项
我想这应该是从sonata管理包开始时首选的方法。
我遇到了同样的问题，出于某种原因，我忽略了，而不是在过去的项目中，我做了完全相同的事情。。。经过一个小时的搜索，我意识到我的表"fos_user_user_group"还没有创建，映射也没有创建。因此，我的解决方案只是覆盖我的实体User的groups属性，以便定义条令ORM映射：
/**
* The User can have many groups.
* @ORM'ManyToMany(targetEntity="Group")
* @ORM'JoinTable(name="fos_user_user_group",
* joinColumns={@ORM'JoinColumn(name="user_id", referencedColumnName="id")},
* inverseJoinColumns={@ORM'JoinColumn(name="group_id", referencedColumnName="id")}
* )
*/
protected $groups;
之后，学说：图式：更新——力量和问题得到了解决；）
如果你像我一样，先创建数据库，然后通过控制台创建yml文件和类，那么你的注释就没用了。
Sonata使用yml而不是注释。它们是存在的，看起来是有效的，但它们就是不起作用。要发出"类不存在"的消息，请检查yml定义所说的内容。我需要在那里添加关系和实体类。
如果这确实是导致错误的原因，您可能希望通过删除或移动yml或xml模板来激活注释（..''Resources''config''doctrine）。
