Laravel可以和belongsToMany一起使用吗？ [英] Can Laravel hasOne be used with belongsToMany?

问题描述

假设我有两个表：

用户：id，name，country_id

国家：id，名称

当然每个 user 只能有一个国家/地区，但每个国家/地区 code>用户。

所以有一个用户使用 hasOne 和国家使用的模型的模型belongsToMany 方法？

文档使其看起来像你不能混合和匹配不同类型的关系。

解决方案

你所描述的是一个一对多关系，一个国家有很多用户。您的国家/地区模型应使用 hasMany 关系，而您的用户将拥有 belongsTo 关系。

Let's say I have two tables:

Users: id, name, country_id

Countries: id, name

Of course each user can only have one country, but each country is assigned to multiple users.

So would it be safe to have a User model that utilizes hasOne and a Country model that uses belongsToMany method?

Documentation makes it seem like you can't mix and match different types of relationships.

解决方案

What you are describing is actually a One To Many relationship, where one country has many users. Your Country model should utilize a hasMany relationship, while your user would have a belongsTo relationship.
