Backbone在破坏模型时试图破坏集合

Question

我是Backbone的新手，所以答案很简单。

我有一个由多态模型组成的集合，所以当我获取时，我通过构造函数运行数据来实例化正确的模型类型：

    Entities.Posts = Backbone.Collection.extend({
    url: 'feed',
    model: function(data) {
        if (data.created_at != undefined) {
            if (data.plantType != undefined) {
                if (data.quantity != undefined) {
                    //it's a want
                    console.log('its a want jim');
                    return new Entities.Want(data);
                } else {
                    //it's a plant
                    console.log('its a plant jim');
                    return new Entities.Plant(data);
                }
            } else {
                //it's an offer
                console.log('its an offer jim');
                return new Entities.Offer(data);
            }
        } else {
            //default type to prevent uncaught error
            return new Entities.Post(data);
        }
    }

工作正常，每个人都很开心。直到我尝试从其视图中删除模型：

        deletePlant: function(e) {
            console.log('delete clicked');
            this.model.destroy({success: function(model, response){
                console.log('plant delete success');
            }, 
            error: function(model,response) {
                console.log(response);
            },
            dataType: 'text/html'});
        App.trigger('posts:list');
    }

这会从服务器中删除模型并将其从集合中删除，但是从模型/ [：id]＆＃39;中删除模型后，骨干网会发送＆＃39; DELETE / feed＆＃ 39;这毫无意义。服务器返回404，因为/ feed没有DELETE路由。当我销毁属于该集合的模型时，为什么要向集合URL发送删除？

感谢。

编辑：以下是给我提问的模型代码。

App.module('Entities', function(Entities, App) {

    Entities.Plant = Backbone.Model.extend( {
        urlRoot: '/plants'
    });

    Entities.Plants = Backbone.Collection.extend( {
      url: 'plants',
          model: Entities.Plant,
        comparator: 'created_at'
    });
});
