BookhshelfJS：附加一对一关系

Question

我有两个 table，User 和 Address。我的tableUser有两个方法：

shippingAddress: function() {
    var Address = require(appRoot + '/config/db').model('Address');
    return this.belongsTo(Address, 'shipping_address_id');
},

billingAddress: function() {
    var Address = require(appRoot + '/config/db').model('Address');
    return this.belongsTo(Address, 'billing_address_id');
}

如何附加一个 Address 来表达我的 shippingAddress？我尝试了以下方法：

new Address(addressQuery)
    .fetch()
    .then(function (address) {
        new User(userQuery)
            .fetch()
            .then(function (user) {
                // Nothing here works
                // I tried the following:
                user.shippingAddress().attach(address); // Attach is not defined
                user.shippingAddress().sync(address);   // Nothing happens
                user.shippingAddress().set(address);    // Nothing happens
                user.save();
            });
    });

我唯一能做的就是：

user.attributes.shipping_address_id = address.id;
user.save();

这不是一个非常优雅的解决方案。我做错了什么？

Answer 1

首先，设置关系列表"withRelated"

new User(userQuery)
        .fetch({
            withRelated:['shippingAddress']
        })
        .then(function (user) {

那么你可以这样做：

user.related('shippingAddress').set(...).save();

确保 shippingAddress() 不是您的用户模型中的 'static' 函数
