laravel - 如何在 laravel eloquent 中连接三列

Question

我有一个用户表。现在，用户既可以是贷方，也可以是借方。他们俩都可以拥有多笔贷款。现在我想在这三个表之间创建一个关系。这就是我想要的。

# A user can be a lender or borrower
# Both lenders and borrowers can have multiple loans.
# One borrower can have one loan only (typical one-to-one relationship).
# One loan can belong to multiple lenders. (later I want to distribute the loan).

我也尝试过多态关系，但那些只属于一张表。但我希望单笔贷款适用于一个借款人和多个贷方。

现在，我如何在 laravel eloquent 中做到这一点？
