我试图让这个工作:

link_to("#", class: "add_fields btn btn-success") do
  name
  content_tag(:i, "", :class => "icon-plus icon-white")
end

但它只显示i(twitter-bootstrap css)指定的图标而不是文本name,我做错了什么？

我已经在我的Rails 3.1应用程序上成功配置了https://github.com/galetahub/ckeditor的ckeditor gem .我现在的问题是我无法弄清楚如何配置CKEditor.在启用了资产管道的Rails 3.1应用程序中,根据自述文件使用的文件根本不存在.

我已经创建了一个Rails可安装应用程序并添加了'mongoid'和'rspec'gem.如果我现在尝试运行我的规格,我会收到以下错误:

Mongoid::Errors::NoSessionConfig: 
Problem:
  No configuration could be found for a session named 'default'.
Summary:
  When attempting to create the new session, Mongoid could not find a session configuration for the name: 'default'. This is necessary in order to know the host, port, and options needed to connect.
Resolution:
  Double check your mongoid.yml to make sure under the sessions key that a configuration exists for 'default'. If you have set the configuration programatically, ensure that 'default' exists in the configuration hash. …

我有一个RSpec测试/lib/classes,需要访问一个zip文件(没有上传).该文件存储在/spec/fixtures/files/test.zip.如何输入正确的路径以使其与环境无关,即没有绝对路径？

我有一个使用rails 3.2和Devise的应用程序.我有一个使用rspec和Capybara的请求测试套件.

我试图在我的登录帮助中转而使用Warden测试助手,而不是让Capybara填写登录表单并提交.由于我的测试套件的大小和复杂性,这导致我的测试运行时节省超过一分半.

在我的配置是:

RSpec.configure do |config|
  config.include Warden::Test::Helpers, :type => :request
  config.after :each do
    Warden.test_reset!
  end
end

并在上下文中:

let!(:current_user) { FactoryGirl.create(:user) }

background do
  login_as(current_user, :scope => :user)
end

但是,当使用这些配置运行测试套件时,几乎每个测试运行都会有一个不同的随机失败的请求规范,因为页面呈现就好像用户没有登录一样.(具体来说,由user_signed_in?条件控制的链接)

我的问题:是否有其他人遇到过这种不可靠性以及如何减轻这种不可靠性？

我想在我的工厂中干掉后创建/构建钩子:

FactoryGirl.define do

  factory :poll do

    sequence :title do |n|
      "MyPollTitle#{n}"
    end
    sequence :description do |n|
      "MyPollDescription#{n}"
    end
    user

    factory :poll_with_answers do

      ignore do
        answers_count 2
      end

      after(:build) do |poll, evaluator|
        evaluator.answers_count.times do
          poll.answers << build(:answer, poll: poll)
        end
      end

      after(:create) do |poll, evaluator|
        evaluator.answers_count.times do
          poll.answers << create(:answer, poll: poll)
        end
      end
    end
  end
end

我面临的问题是,我似乎无法在FG中定义方法？想法如何干这个？

对于rails模板,我想在新的rails应用程序中添加特定标签的子模块.为了保持这个简单,我想避免进入子目录并在那里运行git命令.

git submodule add --branch v1.3.37 git@example.com:foo.git vendor/foo

是我想要使用的,但它不接受--branch参数的标签:

fatal: 'origin/v1.3.37' is not a commit and a branch 'v1.3.37 cannot be created from it Unable to checkout submodule 'vendor/foo'

有没有一种简单的方法在特定标签上添加git子模块？

我已经为我的rails 3.2应用程序编写了一些RSpec测试,因为我被浏览器弹出了ich试图从firefox改为capybara-webkit.在此之后,所有测试仍在运行,除了一个.失败的线是:

expect { click_button "Create" }.to change(Answer, :count).by(count)

如果我删除了expect并添加了一个方法来截取前后的截图,我可以看到测试运行正常.但是,如果我通过调试器进入低谷,日志会显示在第二个屏幕截图行之后创建记录.我可以永远等待click_button,并在执行第一行后运行相应的Controller操作.

"创建"按钮是标准的html按钮,创建操作中不涉及JS.某人对这种奇怪的行为有解释吗？

我有以下初始化程序:

应用程序/配置/初始化/ store_location.rb

module StoreLocation

  def self.skip_store_location
    [
        Devise::SessionsController,
        Devise::RegistrationsController,
        Devise::PasswordsController
    ].each do |controller|
      controller.skip_before_filter :store_location
    end
  end

  self.skip_store_location
end

我的ApplicationController的相关部分:

class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter :convert_legacy_cookies
  before_filter :store_location

  alias_method :devise_current_user, :current_user

  def current_user
    # do something
  end

  private
  def store_location
    # store location
  end

另外在 config/environments/development.rb中

Foo::Application.configure do
# normal rails stuff
config.to_prepare do
    StoreLocation.skip_store_location
  end
end

如果我让RSpec/Rails运行self.skip_store_location,我收到以下错误:

/foo/app/controllers/application_controller.rb:7:in `alias_method': undefined method `current_user' for class `ApplicationController' (NameError)

如果我删除了呼叫,一切都恢复正常(除了按预期运行过滤器).我猜我以某种方式搞乱了依赖加载？

我的模板之一中有以下 haml 代码：

%b= t ('activerecord.attributes.exercise.title') + ':'

有没有更优雅的方法来实现这一目标？最好是oneliner，没有括号。

rspec希望您的控制器规格在/ spec/controllers中.我有一些模块包含在我的控制器中.正如我所知,测试它们的唯一方法是创建一个虚拟控制器,在其中包含模块,然后从那里进行测试.问题是模块规格在/ spec/lib/module中,因此不包含ControllerExampleGroup,这意味着我无法调用辅助方法得到"动作"等.

我可以手动导入这些,这让我大部分都在那里,但我得到这个错误:

我正在尝试测试我的标题标签application/layout.html.erb:

<title><%= content_for?(:title) ? yield(:title) : "Foo Bar" %></title>

但我发现无法设置title变量:

it "should show a title" do
  # NameError: `title' is not allowed as an instance variable name
  #view.instance_variable_set(:title, 'Test Title')

  # Deprecation error
  # view.stub(:title) { 'Test Title' }

  # Fail:
  # allow(view).to receive(:title) { 'Test Title' }
  # view.content_for(:title) { 'Test Title' }
  # assign(:title, 'Test Title')
  # helper.stub(:content_for).with(:title).and_return('Test Title')

  render

  expect(rendered).to have_title('Test Title')
end

我正在使用Rails 4.1.4,rspec-rails 3.0.2,Capybara 2.4.1.有什么建议？

我有:

val = [{uid: '1', ignore: 'i1'}, {:uid: '2', ignore: 'i2'}]

现在我想将部件提取:uid到一个数组中:

arr = []
val.each { |u| u.map { |k,v| arr << v if :uid == k } }

是否有更优雅/更短的方式来写最后两行？
