我有一个全新的cordova3.1.0-0.1.0安装.我创建了这样一个项目cordova create project com.example.project Project.该项目是在项目/ www下创建的,但是文件cordova.js is missing.

我正在使用Windows XP,节点0.10.20和npm 1.3.11.

我错过了什么吗？

当我在JS代码上出错时,我有这种堆栈跟踪:

Error while processing route: admin.subscriptions/edit The adapter operation was aborted Error

    at XMLHttpRequest.r (http://test.com/assets/vendor-160ad2febac0712c4d0db4e856197579.js:50:30564)

正如您所看到的,它是缩小的文件,它似乎不使用源映射文件.源映射文件运行良好.它在Chrome和Firefox上执行此操作.

我怎样才能有更好的堆栈跟踪？

在rails应用程序中,我有以下错误消息:

This installation of RMagick was configured with ImageMagick 6.6.9 but ImageMagick 6.7.7-10 is in use.

我尝试RMagick按照这篇文章的建议卸载并安装:RMagick抱怨它配置了不同版本的ImageMagick,但它不起作用.

我也尝试下载最新版本并从源代码编译,但它不起作用.

我不知道如何安装ImageMagick 6.7.7-10.它似乎无法在官方网站上找到.

我正在使用rmagick (2.13.2)和Ubuntu 14.04.

有解决方案吗？

我有这两个容器:

api:
  image: social-learning
  ports:
    - "3000:3000"
  command: bundle exec rails s -p 3000 -b '0.0.0.0'
  volumes:
    - ../api:/app
  expose:
    - "3000"
web:
  image: social-learning-frontend
  ports:
    - "4200:4200"
    - "9000:9000"
  command: ember serve -p 4200
  volumes:
    - .:/app
  links:
    - api
  expose:
    - "3000"

当我做:

docker exec `docker ps -a | grep 'frontend_web_1' | awk '{print $1 }'` curl http://localhost:3000

我总是拒绝连接.我可以通过其IP访问另一个容器,但我更喜欢将其作为localhost.

可能吗？

在rails应用程序中,我在纯ruby中有这个代码:

class LinkCreator
  attr_accessor :animal

  def initialize(animal:)
    @animal = animal
  end

  def call
    "something#{link_id}"
  end

  private

  def link_id
    connection.execute(sql_request).first.first
  end

  def sql_request
    "SELECT field FROM table WHERE field_id = '#{field_id}' LIMIT 1"
  end

  def field_id
    animal.field_id
  end

  def connection
    ActiveRecord::Base.establish_connection(
      adapter:  "mysql",
      host:     ENV["MYSQL_HOST"],
      username: ENV["MYSQL_USERNAME"],
      password: ENV["MYSQL_PASSWORD"],
      database: ENV["MYSQL_DB_NAME"]
    ).connection
  end
end

如您所见,这不是一个模型,而只是一个简单的类.问题在于,更改了activerecord的连接,以及稍后在新连接上执行的其他请求.

是否可以仅在块中建立连接并返回到旧连接.我知道我可以建立另一个连接,但这对性能非常不利.

我有一个新的rails引擎,我想使用globalize3.我在我的lib // engine.rb中做了这个:

require 'globalize3'

module SimpleCms
  class Engine < ::Rails::Engine
  end
end

现在,我尝试创建这样的迁移:

class CreatePages < ActiveRecord::Migration
  def up
    create_table :pages do |t|
      t.string :path
      t.timestamps
    end
    Page.create_translation_table! title: :string, body: :body
  end

  def down
    drop_table :pages
    Page.drop_translation_table!
  end
end

我有这个错误:

undefined method `create_translation_table!' for #<Class:0x00000001d5ca18>

我认为没有加载文件'lib/globalize/active_record/migration.rb'.

有解决方案吗

我正在努力phonegap build android,我有这样的信息:

[phonegap] detecting Android SDK environment...
[phonegap] using the local environment
[phonegap] adding the Android platform...
   [error] An error occured during creation of android sub-project. Path not found

Phonegap正在寻找"C:\ Documents and Settings\corbg\.cordova\lib\android\cordova\3.0.0\bin\create".目录"3.0.0"下没有任何内容.我安装了这样的cordova npm install -g cordova.

我跑的时候遇到了一些问题cordova platform add android.

我错过了什么吗？

我尝试将我的应用程序从rails 3.1.3升级到rails 3.2.1,我遇到资产问题.

Rails没有找到我的所有资产,但我认为它们位于正确的文件夹中(例如app/assets/images/logos /). …

我试图通过这个规范:

scenario "Edit a service", js: true do
  service = create_service_for(provider, title: "First service")
  fill_edit_service_form(service)
  expect(page).to have_css('#price', text: '10,00 $')
end

这是使用水豚的标准导轨规格.我使用capybara-webkit用于javascript的所有场景.当我试图传递它时,有时候它会起作用,有时它标记的数据库中有一条丢失的记录,有时我有这个错误:
