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?

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”}
