For my project, I created 2 entities : Recipe & Ingredient. They are a ManyToMany relation. mysql shema
I generated everything from the console (entity & CRUD). But, I can’t save ingredients for recipes, the field ‘ingredients’do not save anything, just Date and Name.
I try add a “cascade={“persist”}” in my entity, but it does not work. thank you in advance for your help !

Answer
In relationship ManyToMany, one-way remove/add is not working. For such manyToMany relationship, you have to call the remove/add methods from both entities $recette->addIngredient($ingredients); $Ingredients->addRecettes($recette);
