小编Mat*_*man的帖子

我在其中一个观点中称之为偏:

<%= render :partial => 'events/attendees', :collection => @attendees %>

但是部分由于某种原因运行了两次...这里是部分:

<% @attendees.each do |user| %>

    <li><%= link_to user.name, user %></li>

<% end %>

并且我验证了rails实际上运行了这个部分两次因为输出显示来自@attendees的每个项目两次

我最近克隆了一个github repo,我试图让它在我的mac上工作.我克隆了它,做了捆绑安装并安装了所有的宝石.当我尝试做"rails server"时,我收到一个错误:

=> Booting Mongrel
=> Rails 3.0.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

这是GA输出代码:

<script type="text/javascript">

  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA_CODE']);
  _gaq.push(['_setDomainName', 'SUBDOMAIN']);
  _gaq.push(['_trackPageview']);
  _gaq.push(['_trackEvent', 'Priority', 'Created (day)', 'Label info', '']);



  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();

</script>

trackEvent行似乎是正确的......但由于某种原因没有跟踪.是因为我离开了值字段为零吗？

我有一个rails应用程序,当用户填写表单时,用新的信用卡ping条纹.然后它完成后重定向回主页.但是,条纹说我正在返回503(我认为这是代码)而不是200.我正在做一个常规的redirect_to:root.如何确保还返回200代码？

我的团队和我正在使用twilio发送短信.一切似乎在其他人的本地机器上运行正常(具有相同的确切代码),除了twilio总是向我返回一个验证错误.我正在将消息发送到他们的"特殊号码",因此它实际上不会发送真正的短信,但它仍会返回验证错误.

这是我们发送消息的一些代码:

def send_sms
  self.from_phone_number = CONFIG['live_twilio'] ? self.customer.assigned_phone_number : CONFIG['test_phone_number']
  self.to_phone_number   = CONFIG['live_twilio'] ? self.customer.customer_phone_number : CONFIG['test_phone_number']

  begin
    report_to_new_relic_insights
    send_message_with_twilio!
  rescue Twilio::REST::RequestError => e
    self.error_description = e.message
  end

  self.dispatched_at = Time.now
  self.save(validate: false)

  return e
end

def send_message_with_twilio!
  unless self.customer.example_customer?
    twilio_params = {
      from: "+1#{from_phone_number}",
      to:   "+1#{to_phone_number}",
      body: self.text
    }

    if ENV['RECORD_TWILIO_STATUSES'].in?(['1', 'true'])
      twilio_params[:status_callback] = "#{CONFIG['secure_domain']}/messages/#{id}/update_status"
    end

    client.account.messages.create(twilio_params)
  else
    # @onboarding_flow
    # don't send the actual SMS to the example customer
    self.customer.send_reply_as_example_customer! if self.customer.first_reply?
  end
end

我安装了Ruby 1.9.2.我用过rvm use 1.9.2,然后当我打字ruby -v时说1.9.2.然后,当我退出终端并重新打开它时,它再次显示1.8.7.

我究竟做错了什么？

首先,在我的application.rb文件和我的environment.rb文件中配置有什么区别？

我读到我需要在environment.rb文件中配置我的timezone默认值.我不太清楚如何做到这一点.到目前为止,我在我的environment.rb文件中有这个:

# Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
SampleApp::Application.initialize!

进行更改后是否需要重新运行rails服务器？还有其他步骤吗？

谢谢!

我正在尝试为我的模型用户创建一个rspec,但每次运行时:

rails g rspec_model User

我得到找不到生成器rspec_model.

我检查了另一个stackoverflow线程,它说确保我有宝石'rspec-rails',我这样做.我究竟做错了什么？这是我的gemfile:

group :test do
  # Pretty printed test output
  gem 'turn', :require => false
  gem 'rspec', '2.0.1'
  gem 'webrat', '0.7.1'
end

group :development do
  gem 'rspec-rails', '2.0.1'
  gem 'sqlite3'
end

我知道这是一个非常简单的问题,但我无法确定在初始安装时主动管理员为您提供的登录/传递更改位置.

我现在正在阅读一些铁轨书籍,似乎无法理解何时使用一种测试而不是另一种.是否有一些简单的规则可以了解何时使用集成测试？

我试图允许自己使用主动管理员为每个模型上传5个图像,但我似乎无法弄清楚如何做到这一点.到目前为止,这是我的activeadmin代码:

ActiveAdmin.register Piece do
  form :html => { :enctype => "multipart/form-data" } do |f|
    f.inputs "Details" do
      f.input :name
      f.input :description
      f.input :cost
      f.input :category
      f.input :photo, :as => :file, :hint => f.template.image_tag(f.object.photo.url(:medium))
    end
    f.buttons
  end

  index do
    column :id
    column :name
    column :cost
    column :category
    column :inventory_count
    column :available_count
    column :materials
    column :created_at
    default_actions
  end
end

我如何一次允许5而不是1？

我建立了一个项目,并一直把它推到git hub.然后我制作了一个文件夹的副本(在我的本地机器上)并开始向它走另一个方向.我在github上创建了一个新的repo,但它不会让我推动更改,因为它仍然认为它是旧回购的一部分.当我更改名称时,它会将本地计算机上的文件重置为上一个回购!在尝试这个之前我保存了一份副本.

基本上我想要做的是在我的当前项目上使用github启动一个新的repo,但保留我过去做的所有git修订.这可能吗？

我已经多次做过这种类型的陈述,但它现在告诉我这个陈述含糊不清.这是错误:

Mysql::Error: Column 'created_at' in where clause is ambiguous: SELECT     COUNT(DISTINCT `tasks`.`id`) AS count_id FROM       `tasks`  LEFT OUTER JOIN `users` ON `users`.`id` = `tasks`.`author_id` WHERE     (created_at >= '2012-01-14 18:38:29')

这是声明:

Task.count(:conditions => ["created_at > ?", 1.month.ago])

我在这做错了什么？
