ruby-on-rails - Spine.js has_many：通过

Question

我仍然对Spine JS感到困惑，它真的很聪明很酷。我看到它支持模型关系，但我似乎找不到任何关于has_many :through关系的信息。

我猜是不可能的，有人知道是不是吗？

晚了五年，但 Spine.js 没有has_many关系。

引用源码，只有belongsTo、hasOne和hasMany：

  Spine.Model.extend({
    hasMany: function(name, model, fkey) {
      if (fkey == null) {
        fkey = (underscore(this.className)) + "_id";
      }
      return this.prototype[name] = function(value) {
        return association(name, model, this, fkey, Collection).refresh(value);
      };
    },
    belongsTo: function(name, model, fkey) {
      if (fkey == null) {
        fkey = (underscore(singularize(name))) + "_id";
      }
      this.prototype[name] = function(value) {
        return association(name, model, this, fkey, Instance).update(value).find();
      };
      return this.attributes.push(fkey);
    },
    hasOne: function(name, model, fkey) {
      if (fkey == null) {
        fkey = (underscore(this.className)) + "_id";
      }
      return this.prototype[name] = function(value) {
        return association(name, model, this, fkey, Singleton).update(value).find();
      };
    }
  });
