Spine.js has_many：通过

Question

我仍然围绕着Spine JS，这是非常聪明的酷东西。我看到它支持Model Relationships，但我似乎无法找到有关has_many :through关系的任何信息。

我猜它不可能，有人知道它是不是？

迟到了五年，但Spine.js没有has_many关系。

引用source code，它只有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();
      };
    }
  });
