我一直在我的服务器上收到此错误: [error] Could not check origin for Phoenix.Socket transport.

我有一个在heroku上运行的Phoenix和JS应用程序,在使用频道的myapp.herokuapp.com上很好.

我遵循heroku自定义域指令,并且在将我的prod.exs配置更改为:url: [scheme: "https", host: "myapp.com", port: 443] from 后,无法加载我的应用程序的javascript : url: [scheme: "https", host: "myapp.herokuapp.com", port: 443]

使用自定义域myapp.com访问应用程序时出现此JS错误:

WebSocket connection to 'wss://myapp.com/socket/websocket?token=undefined&vsn=1.0.0' failed: Error during WebSocket handshake: Unexpected response code: 400

伴随着heroku日志:

在信誉系统gem的RailsCast之后,我将以下代码添加到microposts_controller中

def index
  @microposts = Micropost.paginate(page: params[:page]).find_with_reputation(:votes, :all, order: "votes desc")
  @micropost  = current_user.microposts.build
end

但是除了我在模型中设置的默认范围之外,我的索引操作中没有排序

在我的微博模型中,我有

class Micropost < ActiveRecord::Base
    belongs_to :user
    has_many :retweets
    has_reputation :votes, source: :user, aggregated_by: :sum
    default_scope -> { order('created_at DESC') }

如果我将默认范围更改为

default_scope -> { order('votes DESC') }

它的工作方式只是我想要的索引页面,但打破了我的所有其他页面.

我尝试删除默认范围并留在find_with_reputation方法中,但它仍然没有按投票排序.

我也尝试在像这样的微博模型中的方法中定义范围

  def self.popular
    find_with_reputation(:votes, :all, {:order => 'votes desc'})
  end

并像这样在microposts_controller中创建代码

  def index
    @microposts = Micropost.paginate(page: params[:page]).popular
    @micropost  = current_user.microposts.build
  end

它仍然没有按投票排序.

这是访问微博索引页面的日志输出的副本 https://gist.github.com/anonymous/9745552

我的routes.rb用于微博看起来像这样

  resources :microposts, only: [:create, :destroy, :index] do …

我正在使用TeamTreehouse.com(设置)推荐的虚拟盒设置(vagrant和virtualbox),每次我尝试启动新项目或安装新gem时,都会出现以下错误:

Errno::ENOSPC: No space left on device - /home/treehouse/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/execjs-2.2.1

要么

Errno::ENOSPC: No space left on device - /home/treehouse/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/cache/rails_serve_static_assets-0.0.2.gem

或者当我进入虚拟框时我会得到

/home/treehouse/.rbenv/libexec/rbenv-init: line 151: cannot create temp file for here-document: No space left on
 device

我现在有几个项目,我想我在某个地方消耗了太多空间,但我不知道虚拟盒子的工作原理.它运行Ubuntu 12.04.3 LTS(GNU/Linux 3.8.0-41-generic i686).这是我的df -h日志
