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？
