Bookshelf.js:如何定义交叉关系？

Question

我如何定义hasMany Space - > Accounts关系？

var Space = Bookshelf.Model.extend({
    tableName : 'spaces',
    // Account variable does not exist :/
});

var Account = Bookshelf.Model.extend({
    tableName : 'accounts',
    spaceId   : function() {
        return this.belongsTo(Space);
    },
});

定义这个的正确方法是什么？

根据文件,这应该工作:

    var Account = Bookshelf.Model.extend({
        tableName : 'accounts'
    });

    var Space = Bookshelf.Model.extend({
        tableName : 'spaces',
        accounts  : function() {
            return this.hasMany(Account, 'spaceId'); // spaceId is foreign key for Account table
        }
    });
