Farpost / APIBundle / Controller / DefaultController.php： / p>
public function listAction（$ name）
{
$ repository = $ this-> getDoctrine（） - > getManager（）
- > getRepository（'FarpostStoreBundle：Building'）;
$ items = $ repository-> findAll（）;
$ response = new Response（json_encode（$ items））;
$ response-> headers-> set（'Content-Type'，'application / json'）;
return $ response;
}
另外，app / console原则：schema：validate输出是：
[Mapping] OK - 映射文件是正确的。
[数据库] OK - 数据库模式与映射文件同步。
解决方案
因为实体的名称包含一个下划线 _ ，PSR-0自动装载机将尝试在 Farpost / StoreBundle / Entity / Building / type.php 中找到它。 / p>
您需要将您的课程重命名为 BuildingType 并将其放在 Farpost / StoreBundle / Entity /BuildingType.php
I have Symfony project, in which there are 2 entities - Building and Building_type. They are connected with ManyToMany uni-directional association. So, when I try to access my controller, I have this error:
The target-entity Farpost\StoreBundle\Entity\Building_type cannot be found in 'Farpost\StoreBundle\Entity\Building#building_types'.

->getRepository('FarpostStoreBundle:Building');
$items = $repository->findAll();
$response = new Response(json_encode($items));
$response->headers->set('Content-Type', 'application/json');
return $response;
}
Also, app/console doctrine:schema:validate output is:
[Mapping] OK - The mapping files are correct.
[Database] OK - The database schema is in sync with the mapping files.
解决方案
Because the name of the entity contains an underscore _ and the PSR-0 autoloader will try to find it in Farpost/StoreBundle/Entity/Building/type.php.
You need to rename your class to BuildingType and put it in Farpost/StoreBundle/Entity/BuildingType.php
