Laravel雄辩的多对多查询where [英] Laravel Eloquent Many-to-Many query whereIn

问题描述

在我的应用程序中，我已将关系从one-to-many更新为many-to-many，并且我试图找到一种方法来保持关联的功能.

In my application I have updated a relationship from one-to-many to many-to-many and I'm trying to figure out a way to persist associated functionality.

假设我有两个相关的表格，例如狗和主人.如果我有很多主人，并且试图获取这些主人的狗证的清单，我该如何雄辩地做到这一点?

Let's say I have two related tables, e.g. dogs and owners. If I have an array of owners and I'm trying to get a list of dogs id's for those owners, how should I do it eloquently?

那么，我怎么得到Owner在数组中的Dog模型?

So, How would I get the Dog models where Owner is in an array ?

与$associatedDogs = Dog::whereIn('owner_id',$ListOfOwners)->get();相同的是用于One-To-Many关系，但适用于Many-to-Many.

Same thing as $associatedDogs = Dog::whereIn('owner_id',$ListOfOwners)->get(); is for a One-To-Many relationship, but for Many-to-Many.
