小编sim*_*imo的帖子

在我的docker-compose中:

laravel:
    image: trackware
    links:
        - postgis:postgis
    ports:
        - "80:80"
        - "3306:3306"
        - "443:443"
        - "220:22"
        - "8000:8000"
    net: "host"
    restart:  always
    volumes:
        - C:/H/repositories/pubnub:/share
    container_name: laravel

postgis:
    image: mdillon/postgis
    env_file: .postgis_env
    ports:
        - "9090:9000"
        - "54320:5432"
    container_name: postgis

如果我跑,docker-compose up -d我得到这个错误:

Conflicting options: host type networking can't be used with links. This would result in undefined behavior

那么,net: "host"在链接到postgis容器时我将如何使用？laravel容器需要运行pubnub客户端,这需要高性能的网络来实现实时消息处理,还需要链接到postgis容器来访问db.

那么,有什么建议吗？我正在使用docker 1.10.2

我试图Student在测试中创建一个记录,如下所示:

student= Student.create!(:work_phone => "1234567890")

但我得到这个错误:

ActiveRecord::UnknownAttributeError: unknown attribute: work_phone

但是,work_phone在Student模型中定义并进行迁移.

这是Student模型:

class Student < ActiveRecord::Base

  validates_length_of :work_phone, :is => 10, :message => 'must be 10 digits, excluding special characters such as spaces and dashes. No extension or country code allowed.', :if => Proc.new{|o| !o.work_phone.blank?}

  attr_accessible:work_phone

end

任何的想法？

我注意到,如果在模块启用后向模块添加了新的挂钩,则不会调用新的挂钩.

我正在尝试添加hook_node_view,以控制我的模块中的内容类型的视图,我正在使用我正在解决的内容类型的基本名称:lesson_node_view

有人可以向我解释一下吗？以及如何解决这个问题？

谢谢

我想在Cassandra表中获取最后一行.怎么弄？任何的想法？

我正在开发一个项目,我用cassandra替换mysql.我想摆脱所有的SQL查询并将它们全部写在cassandra中.

为什么我会收到此错误？

我注意到这个问题发生在我之后bundle update,任何图像都会出现错误..我会尝试在这里添加详细信息:

我正在尝试为我的模型做一个简单的测试Course,我写了这个工厂:

FactoryGirl.define do
  factory :course do
    name 'How to be happy ?'
    end
end

course_spec.rb:

require "rspec"
require 'factory_girl_rails'
describe "When a course is created" do

  it "can't be deleted if any student is enrolled to it" do
    FactoryGirl.find_definitions
    course = FactoryGirl.build(:course)

    student= Student.create!
    course.students << student
    course.destroy
    course.name.should !=nil
  end
end

但是,我达到了这条线

course = FactoryGirl.build(:course)

我收到错误:

FactoryGirl::DuplicateDefinitionError: Factory already registered: course

如果我在工厂评论:课程定义,我得到:

NameError: uninitialized constant Course

有什么好主意吗？

我尝试在我的WPF应用程序中安装和使用字体,但我得到的是这样的:

这是我尝试使用该字体的代码:

richtext1.FontFamily = "SH_Roq'a";

预期的结果是:(从MS Word快照)

如果我尝试将字体文件添加到项目文件夹,并将其用作资源,如下所示:

richtext1.FontFamily = "./#SH_Roq'a";

我不会得到方形结果,但是,我也没有预期的字体!我得到的是Tahoma字体:

这不是目标字体,请在此下载目标字体文件进行实验

任何帮助表示赞赏!

编辑

上述捕获文本的纯文本是:

因此对于那些使用字体的专家来说,他们可以进行实验.

当我启动服务器时，出现此错误：

I18n::InvalidLocaleData

虽然，yaml 文件在第 2 行第 3 列看起来很正常：

任何的想法？
