角度误差：对象有没有方法推 [英] angular error : object has no method push

问题描述

我试图做一个角度工作，REST服务和 $资源。

I am trying to make a angular work with a REST service and $resource.

它的工作原理，从JSON获得DATAS，但蒙山 $更新保存（）或调用自定义方法 $ REC（），我在控制台的错误说：类型错误：对象＃＆LT; C＆GT;没有方法推。开关 IsArray的到真正或假，并没有改变任何东西。

it works to GET the datas from JSON, but when updating whith $save() or a custom method called $rec(), i have an error in the console saying : TypeError: Object #<c> has no method 'push'. Switching isArray to true or false, didn't change anything.

我犯了一个plunker： http://plnkr.co/edit/fS2bjRKPgUulTbTxgg2j

当你做你自己的服务器上运行的错误是可见的。

the error is visible when you make it run on your own server.

在html：

<div ng-controller="TestCtrl">
    <div ng-repeat="obj in objs">
        <div>
          <h3>{{obj.name}}</h3>
          <h3>{{obj.age}}</h3>
          <input type="text" ng-model="obj.name" /><br />
          <input type="text" ng-model="obj.age" /><br />
          <button ng-click="save(obj)">Save</button>
        </div>
      </div>
    </div>

和JavaScript的：

and the javascript:

'use strict';
angular.module('TestApp', ['TestApp.services', 'TestApp.controllers']);

angular.module('TestApp.services', ['ngResource']).
  factory('Obj', function($resource){
return $resource('datas.json', {}, { 'rec': {method: 'POST', isArray: true } });
});

angular.module('TestApp.controllers', []).
controller('TestCtrl', ['$scope', 'Obj', function($scope, Obj) {
    $scope.objs = Obj.query();
    $scope.save = function(obj) {
        obj.$save();
            console.log(obj);
    }
}]);

你知道错误从何而来？

do you know where the error comes from ?

推荐答案

我抄你的plnkr到我的dev的机器上，建立一个网站西纳特拉下面，但我还没有看到这个错误。在客户的帖子JSON字符串如 {名=＆gt;中露易丝，年龄=＆GT;32} 当我点击一个蓝色的按钮，一切似乎都很好。你处​​理 POST 是否正确？

I have copied your plnkr to my dev machine, set up a sinatra site as below but I still do not see this error. the client posts a JSON string like {"name"=>"louise", "age"=>"32"} when I click on a blue button, and everything seems fine. Are you handling the POST appropriately?

这是我的服务器code：

here is my server code:

app.ru

# -*- coding:utf-8; mode:ruby; -*-

require 'json'
require 'multi_json'
require 'sinatra/base'
require 'sinatra/json'

class App < Sinatra::Base
  helpers Sinatra::JSON

  get '/datas.json' do
    json([
          {"name" => "louise", "age" => "32"},
          {"name" => "jeanne", "age" => "25"},
          {"name" => "renée", "age" => "21"},
          {"name" => "fernande", "age" => "28"}
         ])
  end

  post '/datas.json' do
    data = JSON.parse request.body.read.to_s
    200
  end
end

config.ru

# -*- coding:utf-8; mode:ruby; -*-

require './app.rb'
run App
