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;
食谱
/** * @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();
但是这会抛出以下消息的异常:
A new entity was found through a relationship that was not configured
to cascade persist operations:
Entities\User@00000000408bd010000000007cb1380e. Explicitly persist the
new entity or configure cascading persist operations on the
relationship.
如何正确创建和保存FavoriteRecipe实体?
您是否为所有关系实体设置了级联选项?这是通过为excample设置cascade属性来完成的:cascade = {“persist”,“remove”}
