我的Backbone模型看起来像这样(coffeescript)：

class Invitation extends Backbone.Model
  urlRoot: '/invitations'

然后是表单发送邀请的模板.我试图尽可能接近普通的rails形式,因为看起来Rails最好处理：

<form action="/invitations" accept-charset="UTF-8" id="new_invitation" class="new_invitation" method="post">
  <input id="invitation_recipient_name" class="invitation_recipient_name" type="text" name="invitation[recipient_name]" />
  <input id="invitation_recipient_email" class="invitation_recipient_email" type="text" name="invitation[recipient_email]" />
  <input type="submit" class="btn primary" name="commit" id="invite" value="Send Invitation" />
</form>

这是我的模型和模板的Backbone View

class InvitationView extends Backbone.View
  # this is the template shown above
  template: JST['backbone/templates/invitation']
  events:
    'click #invite': 'sendInvite'

  render: ->
    $(this.el).html this.template()
    this
  sendInvite: (e) ->
    e.preventDefault()
    name = this.$('#invitation_recipient_name')
    email = this.$('#invitation_recipient_email')
    this.model.save
      recipient_name: name.val()
      recipient_email: email.val()

问题是当我单击提交按钮并调用sendInvite方法时,我的服务器接收具有以下结构的数据：

Parameters: {"recipient_name"=>"A name","recipient_email"=>"name@example.com","invitation"=>{"recipient_email"=>"name@example.com","recipient_name"=>"A name"}}

现在这实际上是有效的,因为我的邀请#create动作期望使用以下形式的参数：params [：invitations],这是rails的标准.然而,在请求中发送两次名称和电子邮件的事实似乎表明我的设置出了问题.

我做错了什么或这是对的吗？

如果有人想看到它,这是我的控制器动作：

# POST /invitations
  def create
    @invitation = current_user.sent_invitations.new params[:invitation]

    respond_to do |format|
      if @invitation.save
        format.json { render_for_api :invitation,json: @invitation,status: :created }
      else
        format.json { render json: @invitation.errors,status: :unproccessible_entity }
      end
    end
  end

编辑如果我设置属性并在保存之前记录它,这就是我的邀请模型：

Invitation
    _changed: false
    _changing: false
    _escapedAttributes: Object
      __proto__: Object
    _prevIoUsAttributes: Object
      recipient_email: "dave@example.com"
      recipient_name: "Dave"
      __proto__: Object
    attributes: Object
      recipient_email: "dave@example.com"
      recipient_name: "Dave"
      __proto__: Object
    cid: "c17"
    __proto__: ctor

该日志由以下代码btw生成：

sendInvite: (e) ->
    e.preventDefault()
    name = @$('#invitation_recipient_name')
    email = @$('#invitation_recipient_email')
    @model.set recipient_name: name.val(),recipient_email: email.val()
    console.log "THe model to save",@model

编辑2
这就是我在路由器中实例化我的视图的方式.我应该如何更改这一点,以便Backbone自动跟踪我的模型属性,即使我没有从服务器获取和设置它们？

var TeamRouter = Backbone.Router.extend({
    routes: {
      'members': 'members'
    },members: function() {
      @invite = new MoveOutOrg.Models.Invitation();
      @inviteView = new MoveOutOrg.Views.InvitationView({
        model: @invite
      });
      $('#stage').append(@inviteView.render().el);
    }
  });
