Question

我在项目中使用loopback，并且我有一个与SellerRequests模型相关的MyUser模型（hasMany）。

我看到我现在可以在/ api / MyUsers /：id / sellerRequests上发布一个POST来创建一个链接到用户的新的sellerRequest，但我想做的是在我的common / my-user中使用这个远程方法.js文件。

我尝试做一个MyUser .__ create__sellerRequests，但这是未定义的（对于MyUser.prototype .__ create__sellerRequests和MyUser.createSellerRequests也是如此）。知道如何访问远程方法吗？

谢谢！

// here is my common/my-user.js file
module.exports = function(Myuser) { 
    console.log(Myuser.__create__sellerRequests); // This is undefined
}

// Here is my MyUser.json

获取用户实例并使用此

<user instance>.sellerRequests.create(data, function(error, result) {

});

其中data是包含SellerRequest模型的字段和值的对象。

或使用此

MyUser.sellerRequests({customer_id: <user_id>, <rest of the fields in seller requests>}, function(error, result) {

});

参考：Methods available to the model。

环回使用关系的远程方法
