Laravel 4.1 Eloquent - 使用 whereHas 的自定义连接

Question

我使用的 MSSQL 有 2 个连接，名为 Seven_ora(User 模型的表在其中)和 sho(Character 模型的表在其中)。

一个用户有多个字符，一个字符属于用户。

当我尝试:

Character::whereHas('User', function($q) { $q->where('gm', 1); });

它似乎使用与 Character 相同的连接。似乎 whereHas 中的闭包是一个 Query\Builder？我希望 whereHas 使用它所指的任何模型的相应集合连接。

有没有办法在我的 whereHas 闭包上使用不同的连接？

Answer 1

将数据库名称添加到 User 类中的 $table 值中。因此假设 Seven_ora 也是数据库的名称:

protected $table = 'seven_ora.userinfo';
