我正在使用自动保存回原始文件作为我的组织模式,但我只希望它适用于此模式而不是其他任何东西.那很容易吗？

这是我的组织模式选项

;; Org-mode options
(add-hook 'org-mode-hook
          'turn-on-visual-line-mode
          'auto-save-mode)
(add-hook 'org-mode-hook '(lambda()
                (setq auto-save-visited-file-name t)
                (setq auto-save-interval 20)))

注意:有关我的完整配置,请参阅https://github.com/map7/simple_emacs

在我的rails 3.0应用程序中,我有一组check_box_tags,每个都有一个标签.我希望这些复选框的标签能够保留它们的情况.

EG:'学校/学院'标签变成'学校/学院',任何缩写如'RAAF'在check_box_tag中使用时变成'Raaf'.这是我正在使用的代码:

%h2 Chaplains
- for chaplain in Chaplain.all
= check_box_tag "clergy[chaplain_ids][]",chaplain.id,@clergy.chaplains.include?(chaplain)
= f.label chaplain.name
%br

我在ruby 1.9.3p0上使用rspec 2.8.1运行rails 3.2.1,并且在运行我的测试时它显示负时间值.这很烦人,因为我正在尝试优化我的测试.

Running: spec/models/transaction_spec.rb
................................................

Finished in -7603162.49414 seconds

我已经尝试将rspec更新到2.9.0,但这没有帮助.

我有一个自定义绑定来处理自动完成,当用户从自动完成中选择一个项目时,我会与服务器通信并用缩短的名称替换text_field.问题是这会第二次触发我的自定义绑定的"更新"功能.

Knockout.js代码(编辑:注意以下是CoffeeScript):

ko.bindingHandlers.ko_autocomplete =
  init: (element, params) ->
    $(element).autocomplete(params())

  update: (element, valueAccessor, allBindingsAccessor, viewModel) ->
    unless task.name() == undefined
      $.ajax "/tasks/name",
        data: "name=" + task.name(),
        success: (data,textStatus, jqXHR) ->
          task.name(data.short_name)


  Task = ->
    @name = ko.observable()
    @name_select = (event, ui) ->
      task.name(ui.item.name)
      false  

  task = Task.new()

视图

= f.text_field :name, "data-bind" => "value: name, ko_autocomplete: { source: '/autocomplete/tasks', select: name_select }"

有没有办法将油门应用于自定义绑定？

我只想在将task.name设置为从服务器发回的short_name时再次触发自定义绑定'更新'功能.

我刚刚升级到ruby 1.9.3-p125(从1.9.3-p0开始).所有测试在升级之前都有效.现在,在运行rake功能时出现以下错误

我刚刚升级了我的整个发行版，我正在尝试使用以前的设置来设置我的 emacs，当使用我的“magit”插件并输入“Mx magit-status”时，我收到以下错误：

我正在使用 Rails 2.3.8 并接受_nested_attributes_for。

我有一个简单的类别对象，它使用 awesome_nested_set 来允许嵌套类别。

对于每个类别，我想要一个名为 code 的唯一字段。对于每个级别的类别，这将是唯一的。这意味着父类别都将具有唯一的代码，子类别在其自己的父类别中将是唯一的。

例如：

code name
1    cat1
   1 sub cat 1
2    cat2
   1 sub cat 1
   2 sub cat 2
3    cat3
   1 sub1

这无需验证过程即可工作，但是当我尝试使用以下内容时：validates_uniqueness_of :code, :scope => :parent_id

这将不起作用，因为尚未保存父级。

这是我的模型：

class Category < ActiveRecord::Base
  acts_as_nested_set
  accepts_nested_attributes_for :children, :reject_if => lambda { |a| a[:name].blank? }, :allow_destroy => true

  default_scope :order => "lft"

  validates_presence_of :code, :name, :is_child
  validates_uniqueness_of :code, :scope => :parent_id
end

我已经想到了一种不同的方法来做到这一点，它非常接近工作，问题是我无法检查子类别之间的唯一性。

在第二个示例中，我在名为“is_child”的表单中嵌入了一个隐藏字段，以标记该项目是否为子类别。这是我的这个模型的例子：

class Category < ActiveRecord::Base
  acts_as_nested_set
  accepts_nested_attributes_for :children, …

我正在尝试使用chef-solo在我的服务器上安装postgresql.我通过自己做引导程序并在脚本中手动包含build-esential包来完成这项工作.现在我想使用knife-solo来处理引导,我在定义执行配方的顺序时遇到了问题.

我想在postgresql之前安装build-essential软件包.这是我正在建立的服务器的json文件

{
    "dbuser": "myuser",
    "dbpass": "mypassword",

    "postgresql":{"password":{"postgres":"mypassword"}},
    "passenger":{"version":"3.0.14", "max_pool_size":"2"},
    "default_attributes":{"build_essential":{"compiletime": "true"}},

    "run_list": [ 
        "recipe[build-essential]",
        "role[web_server]",
        "recipe[sqlite]",
        "recipe[postgresql::server]",
        "recipe[pope::default]"
    ]

}

当我发出命令

knife cook <user>@<my server's ip>

我收到这个错误

我有一个AngularJS模型,我在其中创建了一个名为myService的模块,用于保存我在整个应用程序中使用的一些常用代码.我的普通工厂是我一直在添加所有方法的地方,现在我想把它拆分并给它们好名字.

我的很多方法互相调用,所以如何调用另一个工厂的方法呢？

angular.module('myService', ['ngResource'])
  .factory('test2', ($window) ->
    return {
      foobar: () ->
        Common.test()
    }
  )  
  .factory('Common', ($window) ->
    return {
      test: () ->
        alert 'testing'
    }
  )

我在我的Ruby on Rails(5.2.1)项目中使用了带有Selenium(3.14.0)和Capybara(3.8.0)的chrome headless,我有一个测试工作在Non-headless chrome但不在无头chrome中.我在谷歌Chrome稳定版69上使用'--headless'标志.

我用以下设置我的无头镀铬,这适用于所有不下载文件的测试.

download_path="#{Rails.root}/tmp/downloads"

Capybara.register_driver(:headless_chrome) do |app|
  caps = Selenium::WebDriver::Remote::Capabilities.chrome(
    chromeOptions: {
      prefs: {
        'download.default_directory' => download_path,
        "download.extensions_to_open" => "applications/pdf",
        'download.directory_upgrade' => true,
        'download.prompt_for_download' => false,
        'plugins.plugins_disabled' => ["Chrome PDF Viewer"]
      },
      binary: "/opt/google/chrome/google-chrome",
      args: %w[headless disable-gpu window-size=1920,1080]
    }
  )
  Capybara::Selenium::Driver.new(
    app,
    browser: :chrome,
    desired_capabilities: caps
  )
end

我已经读过我应该向selenium chrome驱动程序发送命令以允许下载,但我无法弄清楚如何使用我的设置.这是我想要的工作,但我的设置; (不是来自我的代码库);

@driver = Selenium::WebDriver.for :chrome, options: options

bridge = @driver.send(:bridge)
path = '/session/:session_id/chromium/send_command'
path[':session_id'] = bridge.session_id
bridge.http.call(:post, path, cmd: 'Page.setDownloadBehavior',
                 params: {
                   behavior: 'allow',
                   downloadPath: download_path
                 }) …
