我的学说实体内有以下关系:
FavoriteRecipe
/**
* @ManyToOne(targetEntity="User", inversedBy="favoriteRecipes")
*/
private $user;
/**
* @ManyToOne(targetEntity="Recipe", inversedBy="favoriteRecipes")
*/
private $recipe;
配方
/**
* @OneToMany(targetEntity="FavoriteRecipe", mappedBy="user")
*/
private $favoriteRecipes;
用户
/**
* @OneToMany(targetEntity="FavoriteRecipe", mappedBy="user")
*/
private $favoriteRecipes;
在我的一个控制器中,我有以下代码:
$favoriteRecipe = new \Entities\FavoriteRecipe();
$favoriteRecipe->setRecipe($recipe);
$favoriteRecipe->setUser($user);
$this->_em->persist($favoriteRecipe);
$this->_em->flush();
但是这会引发以下消息的异常:
通过未配置的关系找到新实体 级联持续操作: 实体\用户名@ 00000000408bd010000000007cb1380e。明确坚持 新实体或配置级联持久化操作 关系。
如何正确创建和保存FavoriteRecipe
实体?
答案 0 :(得分:7)
您是否为所有关系实体设置了级联选项?这是通过设置excample的cascade属性来完成的:cascade = {“persist”,“remove”}
