php - 异常“Doctrine\ORM\Mapping\MappingException”，带有消息“在 Y 中找不到目标实体 X

Question

每当我尝试使用 EntityManager 查找或查询具有关联的对象时，我都会收到上述错误。我绝对找不到任何无法找到目标实体的押韵或原因。下面是一些示例代码和错误。我没有编辑具体的名字，因为这可能是一个命名空间问题。

错误：

您似乎引用了错误的实体名称，targetEntity="SGN\Models\BetterButtonTransaction" 应该是 targetEntity="name_of_the_table_as_is_in_the_database"。您不能映射到运行时实体，而是映射到数据库中的表名。
