javascript - 主干 .save() 上的 404 错误

Question

这与我的网址的/:id结尾有关；我想我无法让我的 Mongoose 和 Backbone ID 字段正确匹配。这是完整的控制台错误 POST http://localhost:8080/api/bears/:id 404 (Not Found)

这是我在其中save() 我的模型的 View 。

var HomeView = Backbone.View.extend({
            el:$('#main'),

            render: function(){

                this.template = _.template($('#home_template').html());

                this.$el.html(this.template);

                $('#new-entry').submit(function(ev){

                    var entry = new Entry({task: $('#word').val(), description: $('#definition').val() });

                    dictionary.add(entry);

                    entry.save();

                    console.log(dictionary.toJSON());

                    $('#body').children('input').val('');

                    return false;

                });

            }
        })

这是我的 Mongoose 模式:

var mongoose = require('mongoose');

var Schema = mongoose.Schema,
    ObjectID = Schema.ObjectID;

var EntrySchema = new Schema({
    task: String,
    description: String
});

module.exports = mongoose.model('Entry', EntrySchema);

Mongoose .post() 路线我的定位:

router.route('/bears')
//create a bear
.post(function(req, res){
    var entry = new Entry();

    entry.task = req.body.task;
    entry.description = req.body.description;

    entry.save(function(err){
        if(err)
            res.send(err);

        res.json({message: 'task created'});
    })
});

这是我的模型定义:

var Entry = Backbone.Model.extend({

                urlRoot: '/api/bears/',

                defaults: function(){
                    return{

                        task: '',
                        description: ''
                    }
                },

                parse: function(response){
                    response.id = response._id;
                    return response;
                },

                idAttribute: "_id",
            });

你需要设置 urlRoot在你的模型中:

var Entry = Backbone.Model.extend({

  urlRoot: '/api/bears/',

  defaults: function(){
      return{
          task: '',
          description: ''
      }
  },

  parse: function(response){
      response.id = response._id;
      return response;
  },

  idAttribute: "_id",
});
