[英]Relation ManyToMany with Symfony 5 : do not save
對於我的項目,我創建了 2 個實體:Recipe & Ingredient。 它們是多對多關系。 mysql 神馬
我從控制台(實體和 CRUD)生成了所有內容。 但是,我無法保存食譜的成分,“成分”字段不保存任何內容,只保存日期和名稱。
我嘗試在我的實體中添加一個“cascade={”persist“}”,但它不起作用。 預先感謝您的幫助 !

在多對多關系中,單向刪除/添加不起作用。 對於這樣的多對多關系,您必須從兩個實體中調用刪除/添加方法 $recette->addIngredient($ingredients); $Ingredients->addRecettes($recette);
應該有另一個名為“ingredient_recipe”的表。 多對多關系項目將保存在這里。
