Post Backbone.js-如何通过表单保存模型并发布到服务器

我是BackboneJS/RequireJS中的n00b，我正在开发一个使用RESTful API的web应用程序。 我有一个这样的模型：

型号/pet.js

define([
  'backbone'
], function(Backbone){

var PetModel = Backbone.Model.extend({

    urlRoot: 'http://localhost:3000/pet',
    idAttribute: '_id',

    defaults: {
        petId: "",
        type: "",
        name: "",
        picture: "",
        description: "",
        breed: "",
        size: "",
        sex: "",
        age: "",
        adopted: false,
    }
});

  return PetModel;
});

define([
  'backbone',
  'models/pet'
], function(Backbone, PetModel){

    var PetsCollection = Backbone.Collection.extend({
    url: 'http://localhost:3000/pets',
    model: PetModel,
});

  return PetsCollection;
});

define([
  'jquery',
  'backbone',
  'models/pet',
  'collections/pets',
  'text!templates/pet/addNew.html'
], function($, Backbone, PetModel, PetsCollection, petAddNewTemplate){

var PetAddNewView = Backbone.View.extend({

    el: $('#formAdd'),
    template: _.template(petAddNewTemplate),

    events: {
        'click #add'        : 'submitAdd',
    },

    initialize: function() {
        this.model = new PetModel();
        this.collection = new PetsCollection();
        _.bindAll(this, 'submitAdd');
    },

    render: function() {
        var view = this;
        view.$el.html( view.template );
        return view;
    },


    submitAdd: function(e) {
        //Save Animal model to server data
        e.preventDefault();
        var pet_data = JSON.stringify( this.getFormData( this.$el.find('form') ) );
        this.model.save(pet_data);
        this.collection.add(this.model);
        return false    
    },

    //Auxiliar function
    getFormData: function(form) { 
        var unindexed_array = form.serializeArray();
        var indexed_array = {};

        $.map(unindexed_array, function(n, i){
            indexed_array[n['name']] = n['value'];
        });

        return indexed_array;
    },

});

return PetAddNewView;
});

收藏：collections/pets.js

define([
  'backbone'
], function(Backbone){

var PetModel = Backbone.Model.extend({

    urlRoot: 'http://localhost:3000/pet',
    idAttribute: '_id',

    defaults: {
        petId: "",
        type: "",
        name: "",
        picture: "",
        description: "",
        breed: "",
        size: "",
        sex: "",
        age: "",
        adopted: false,
    }
});

  return PetModel;
});

define([
  'backbone',
  'models/pet'
], function(Backbone, PetModel){

    var PetsCollection = Backbone.Collection.extend({
    url: 'http://localhost:3000/pets',
    model: PetModel,
});

  return PetsCollection;
});

define([
  'jquery',
  'backbone',
  'models/pet',
  'collections/pets',
  'text!templates/pet/addNew.html'
], function($, Backbone, PetModel, PetsCollection, petAddNewTemplate){

var PetAddNewView = Backbone.View.extend({

    el: $('#formAdd'),
    template: _.template(petAddNewTemplate),

    events: {
        'click #add'        : 'submitAdd',
    },

    initialize: function() {
        this.model = new PetModel();
        this.collection = new PetsCollection();
        _.bindAll(this, 'submitAdd');
    },

    render: function() {
        var view = this;
        view.$el.html( view.template );
        return view;
    },


    submitAdd: function(e) {
        //Save Animal model to server data
        e.preventDefault();
        var pet_data = JSON.stringify( this.getFormData( this.$el.find('form') ) );
        this.model.save(pet_data);
        this.collection.add(this.model);
        return false    
    },

    //Auxiliar function
    getFormData: function(form) { 
        var unindexed_array = form.serializeArray();
        var indexed_array = {};

        $.map(unindexed_array, function(n, i){
            indexed_array[n['name']] = n['value'];
        });

        return indexed_array;
    },

});

return PetAddNewView;
});

以及一个视图，该视图呈现一个表单以添加新模型（可能还有另一种更优雅的方式） views/petAddNew.js

define([
  'backbone'
], function(Backbone){

var PetModel = Backbone.Model.extend({

    urlRoot: 'http://localhost:3000/pet',
    idAttribute: '_id',

    defaults: {
        petId: "",
        type: "",
        name: "",
        picture: "",
        description: "",
        breed: "",
        size: "",
        sex: "",
        age: "",
        adopted: false,
    }
});

  return PetModel;
});

define([
  'backbone',
  'models/pet'
], function(Backbone, PetModel){

    var PetsCollection = Backbone.Collection.extend({
    url: 'http://localhost:3000/pets',
    model: PetModel,
});

  return PetsCollection;
});

define([
  'jquery',
  'backbone',
  'models/pet',
  'collections/pets',
  'text!templates/pet/addNew.html'
], function($, Backbone, PetModel, PetsCollection, petAddNewTemplate){

var PetAddNewView = Backbone.View.extend({

    el: $('#formAdd'),
    template: _.template(petAddNewTemplate),

    events: {
        'click #add'        : 'submitAdd',
    },

    initialize: function() {
        this.model = new PetModel();
        this.collection = new PetsCollection();
        _.bindAll(this, 'submitAdd');
    },

    render: function() {
        var view = this;
        view.$el.html( view.template );
        return view;
    },


    submitAdd: function(e) {
        //Save Animal model to server data
        e.preventDefault();
        var pet_data = JSON.stringify( this.getFormData( this.$el.find('form') ) );
        this.model.save(pet_data);
        this.collection.add(this.model);
        return false    
    },

    //Auxiliar function
    getFormData: function(form) { 
        var unindexed_array = form.serializeArray();
        var indexed_array = {};

        $.map(unindexed_array, function(n, i){
            indexed_array[n['name']] = n['value'];
        });

        return indexed_array;
    },

});

return PetAddNewView;
});

所以，当我提交表单时，我不会将任何数据发布到服务器。我不知道怎么修理它。

有什么想法吗？提前谢谢

Model.save

期望新值的对象/散列，就像

Model.set

一样。这里您将传递一个字符串作为attributes参数。

您需要先设置属性，然后保存

//Auxiliar function
getFormData: function(form) { 
    var self = this;
    var unindexed_array = form.serializeArray();

    $.map(unindexed_array, function(n, i){
        self.model.set({
            n['name']: n['value']
        });
    });
}

现在

this.model.save（）

可以工作了（在服务器端保存）

您可以看到它在一个数据库中工作。

为什么不调试主干网中发生的事情？在大多数情况下，这是解决问题的最快方法（与任何开源产品一样）。是的，我在chrome中使用console.log进行了调试，var“pet_data”显示了表单序列化的完整JSON对象，但“save”方法不起作用：（感谢@J-unior我注意到没有在服务器端调试，我已经发现了错误。我现在很高兴：我尝试了“this.getFormData（this.$el.find（'form'）”而不是“JSON.stringify（this.getFormData（this.$el.find（'form'））；”来传递对象，但它也不起作用。谢谢！@Simon Boudrias这个答案帮助我：）在

n['name']

@benjaminullivan后面有一个多余的括号，现在已经修好了。只花了约2年时间
