I am trying to insert data from ember’s view but am getting following error message:<\/p>\n

Uncaught Error: assertion failed: Your server returned a hash with the key refunds but you have no mapping for it\n<\/code><\/pre>\n
and here is my coding can anyone correct it.<\/p>\n
My handlebar<\/p>\n
\n   <\/code><\/pre>\n{{view Ember.TextField valueBinding=\"refund_amount\" placeholder=\"Enter refund amount\"}}<\/code><\/th>\nRefund<\/code><\/td>\n
My js model<\/p>\n
Office.Refund = DS.Model.extend({\n    job_id: DS.attr('number'),\n    customer_id: DS.attr('number'),\n    amount: DS.attr('number')\n});\n<\/code><\/pre>\n
MY js controller<\/p>\n
saveRefund: function() {\n    var refund = Office.Refund.createRecord({\n    job_id: this.get('id'),\n    customer_id: this.get('customer.id'),\n    amount: this.get('refund_amount')\n  });\n    this.get('store').commit();\n    refund.on('didCreate',function() {\n    alert('created successfully');\n  });\n}\n<\/code><\/pre>\n
Here is my refund_controller.rb<\/p>\n
  def index\n    @refund = Thunderbolt::Refund.all\n    respond_to do |format|\n    format.html # index.html.erb\n    format.json { render json: @refund}\n    end\n  end\ndef new\n    @refund = Refund.new\n    respond_to do |format|\n      format.html # new.html.erb\n      format.json { render json: @refund }\n    end\n  end\n\n  def create\n    refunds = params[:refund]\n    @refund = Refund.new(job_id: refunds[:job_id], customer_id: refunds[:customer_id], amount: refunds[:amount])\n    respond_to do |format|\n      if @refund.save\n        format.html { redirect_to @refund, notice: 'Refund successful.' }\n        format.json { render json: @refund, status: :created, location: @refund }\n      else\n        format.html { render action: \"new\" }\n        format.json { render json: @refund.errors, status: :unprocessable_entity }\n      end\n    end\n  end\n<\/code><\/pre>\n
Here is my refund_serializer.rb<\/p>\n
  class RefundSerializer < ActiveModel::Serializer\n    attributes :id, :job_id, :customer_id, :amount, :created_at, :updated_at\n  end\n<\/code><\/pre>\n
Here is my refund.rb model<\/p>\n
  class Refund < ActiveRecord::Base\n    attr_accessible :id, :amount, :customer_id, :job_id, :created_at, :updated_at\n  end\n<\/code><\/pre>\n
    \n
  1. \n
    Solved this error by adding resources :refunds<\/code> in routes.rb<\/code> instead of<\/p>\n
      get \"refunds\/index\"\n\n  get \"refunds\/new\"\n\n  get \"refunds\/edit\"\n\n  get \"refunds\/show\"\n<\/code><\/pre>\n<\/li>\n
  2. \n
    Before the comments are getting to long I’ll try to explain it in an answer. When you post a new record to be saved, your backend should return the new record with an id<\/code> set to it like:<\/p>\n
    {\n  \"refund\": {\n    \"id\": 123,\n    \"job_id\":691,\n    \"customer_id\":424,\n    \"amount\":1\n  }\n}\n<\/code><\/pre>\n
    If job_id<\/code> is your record’s primary key the you need to have a mapping for it in your DS.RESTAdapter<\/code>, do you?<\/p>\n
    Hope it helps.<\/p>\n<\/li>\n<\/ol>\n
