小编pau*_*her的帖子

在过去的几个月里，我们一直在工作中松散地跟踪 git flow，但遇到了漫长的 QA 等待问题。

这是我们的流程：

• 开发人员在功能分支上进行本地开发
• 当团队认为该功能准备就绪时，将其合并到开发中，推送到开发服务器（Codeship & rsync）
• 客户批准功能
• 功能合并到 master，推送到 prod

不幸的是，客户有时可能需要长达数周的时间来批准一项功能。这可能是由于积压、内容创建、人员流动等原因。

但是，与此同时，新功能可能已合并到开发中并推送到开发服务器进行审批。假设第二个功能获得批准并需要尽快部署（当然）。我如何在不带第一个功能的情况下从 dev 中获得第二个功能？

我觉得这应该是非常简单的,但我无法在不同的视图中获取控制器的内容.这是我的代码:

App.MapView = Ember.View.extend({
    elementId: ['map-canvas'],
    didInsertElement: function() {
        var self = this;
        var controller = this.get('controllers.markers');
    }
});

如果我console.log(控制器)我得到undefined.

在控制器中,我会做类似的事情:

App.MarkersController = Ember.ArrayController.extend({
    needs: ['map']
});
App.MapController = Ember.ObjectController.extend({
   plot: function() {
      var markers = this.get('controllers.markers');
   }
});

在Rails 4应用程序中出现问题,我遇到了死锁错误(详情如下).我正在使用'websocket-rails'宝石.

它似乎发生在每个第二个请求,来自dispatcher = new WebSocketRails('localhost:3000/websocket');(来自我的应用程序的前端)

除了github上的faye repo中的旧问题之外,我几乎没有提到这个问题:https://github.com/faye/faye/issues/190

错误:

我正在使用EmberJs并且无法弄清楚为什么以下代码不会呈现"新"模板.当我导航到/商店时,我得到一个商店列表和一个链接到'/ shops/new'的创建按钮,但是当我点击创建时,'新'模板不会呈现,而是与'商店'保持一致.我可以很好地导航到每个单独的商店,而不是新的.

App.js

window.App = Ember.Application.create();

App.Router.reopen({
  location: 'history'
});

// Router
App.Router.map(function() {
  this.resource('shops', function() {
    this.route('new');
  });
  this.resource('shop', { path: '/shops/:shop_id' });
});

App.ShopsRoute = Ember.Route.extend({
  model: function() {
    return App.Shop.find();
  }
});

App.ShopsNewRoute = App.ShopsRoute.extend({
  model: function() {
    return App.Shop.createRecord();
  },
  setupController: function( controller, model ) {
    return this._super(),
    controller.set( 'content', model )
  }
});

App.ShopsNewController = Ember.ObjectController.extend();

// Models
App.Store = DS.Store.extend({
  revision: 11,
  adapter: DS.RESTAdapter
});

App.Shop = DS.Model.extend({
  name: DS.attr('string'),
  body: DS.attr('string'),
});
