emberjs断言失败错误

Question

我试图从ember的视图中插入数据，但收到以下错误消息：

Uncaught Error: assertion failed: Your server returned a hash with the key refunds but you have no mapping for it

这是我的代码，任何人都可以修改它。

我的车把

<form>
   <th>{{view Ember.TextField valueBinding="refund_amount" placeholder="Enter refund amount"}}</th>
   <td><button type="submit" class="btn btn-success complete-btn" {{action saveRefund}}>Refund</button></td>
</form>

我的js模型

Office.Refund = DS.Model.extend({
    job_id: DS.attr('number'),
    customer_id: DS.attr('number'),
    amount: DS.attr('number')
});

我的js控制器

saveRefund: function() {
    var refund = Office.Refund.createRecord({
    job_id: this.get('id'),
    customer_id: this.get('customer.id'),
    amount: this.get('refund_amount')
  });
    this.get('store').commit();
    refund.on('didCreate',function() {
    alert('created successfully');
  });
}

这是我的refund_controller.rb

  def index
    @refund = Thunderbolt::Refund.all
    respond_to do |format|
    format.html # index.html.erb
    format.json { render json: @refund}
    end
  end
def new
    @refund = Refund.new
    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @refund }
    end
  end

  def create
    refunds = params[:refund]
    @refund = Refund.new(job_id: refunds[:job_id], customer_id: refunds[:customer_id], amount: refunds[:amount])
    respond_to do |format|
      if @refund.save
        format.html { redirect_to @refund, notice: 'Refund successful.' }
        format.json { render json: @refund, status: :created, location: @refund }
      else
        format.html { render action: "new" }
        format.json { render json: @refund.errors, status: :unprocessable_entity }
      end
    end
  end

这是我的refund_serializer.rb

  class RefundSerializer < ActiveModel::Serializer
    attributes :id, :job_id, :customer_id, :amount, :created_at, :updated_at
  end

这是我的refund.rb模型

  class Refund < ActiveRecord::Base
    attr_accessible :id, :amount, :customer_id, :job_id, :created_at, :updated_at
  end

Answer 1

通过在routes.rb中添加resources :refunds而不是

  get "refunds/index"

  get "refunds/new"

  get "refunds/edit"

  get "refunds/show"

Answer 2

在评论变得冗长之前，我将尝试在答案中解释它。当您发布要保存的新记录时，您的后台应返回新记录并设置id，如下所示：

{
  "refund": {
    "id": 123,
    "job_id":691,
    "customer_id":424,
    "amount":1
  }
}

如果job_id是你的记录的主键，那么你需要在你的DS.RESTAdapter中为它建立一个映射，对吗？

希望能有所帮助。
