小编pab*_*rti的帖子

我在Apache上使用Passenger生产了一个Rails 3应用程序.我有这个代码:

class Billing < ActiveRecord::Base
  after_save :sendEmails

  private
    def sendEmails
      fork do 
        UserMailer.clientBilling(self.user, self).deliver
      end
    end
end

在localhost中,当应用程序创建帐单时,在保存后,应用程序会向用户发送电子邮件,一切正常.但是在服务器中,在应用程序创建计费之后,它会抛出与gem2M2相关的错误,"MySQL服务器已经消失"或"连接丢失"等错误,并且应用程序不会发送电子邮件.如果我删除fork它工作正常,但我想使用fork,我想创建一个单独的进程,因为它在发送电子邮件时需要很长时间.可能是什么问题呢？

我使用Ruby 1.9.3p0,Rails 3.1.2与Apache和Passenger in Production.当我尝试创建一个远程函数时,它会抛出这个错误:

ActionView::MissingTemplate (Missing template video/loadVideo, application/loadVideo with
{:handlers=>[:erb, :builder], :formats=>[:js, "application/ecmascript", "application/x-
ecmascript", :html, :text, :js, :css, :ics, :csv, :xml, :rss, :atom, :yaml, 
:multipart_form, :url_encoded_form, :json], :locale=>[:en, :en]}. Searched in

正如你所看到的,没有处理程序:coffee,这就是为什么不处理文件video/loadVideo.js.coffee的原因 ; 我运行命令rake assets:precompile但没有任何变化.

Gemfile源'http://rubygems.org'

gem 'rails', '3.1.2'

# Bundle edge Rails instead:
# gem 'rails',     :git => 'git://github.com/rails/rails.git'

gem 'will_paginate', '~> 3.0'
gem "bcrypt-ruby", :require => "bcrypt"
gem 'mysql'

#Problems in Debian, the error was:
#Could not find a JavaScript …

我想在Rails 3.2.9中使用omniauth-facebook登录Facebook; 我已经按照http://railscasts.com/episodes/360-facebook-authentication中的Ryan Bates的步骤进行操作,在这一刻我有相同的代码.

如果我尝试登录没有Javascript它可以工作(我需要Facebook,我授予权限,并让我成功回到应用程序),但如果我尝试使用Javascript(对于Facebook弹出窗口)它最初显示弹出窗口登录,但然后进行重定向并抛出此错误(不要求权限):

Started GET "/auth/facebook/callback" for 127.0.0.1 at 2012-11-16 15:16:03 -0600
(facebook) Callback phase initiated.
(facebook) Authentication failure! invalid_credentials: OmniAuth::Strategies::OAuth2::CallbackError, OmniAuth::Strategies::OAuth2::CallbackError

OmniAuth::Strategies::OAuth2::CallbackError (OmniAuth::Strategies::OAuth2::CallbackError)

这是一个非常常见的错误; 我做了研究并尝试了所有的解决方案(大多数是几个月前),但都没有.这是我尝试过的:

1. 在Facebook中检查沙箱是禁用的(我已经等了几个小时进行传播)
2. 检查站点URL http://localhost:3000/
3. 检查应用程序ID和应用程序密钥
4. 将omn​​iauth-facebook gem 降级为1.4,并将此错误抛给我:omniauth-facebook must pass either a代码parameter or a signed request (viasigned_request parameter or afbsr_XXXcookie)
5. 降级到Rails 3.2.8

我还该怎么办？(我认为关键在于Javascript,现在我有了相同的视频代码,使用CoffeeScript).提前致谢!

我正在尝试制作一个"通用模型",以便它可以连接到任何数据库的任何表.首先,我创建了这个连接到另一个指定数据库的类(不使用模式)

D b

class Db < ActiveRecord::Base

    self.abstract_class = true

    attr_accessor :error

    def initialize(item = nil)
        @error = ""
        connect
        super
    end

    def connect
        could_connect = true
        @error = ""

        begin
            ActiveRecord::Base.establish_connection(
              :adapter  => "mysql2",
              :host     => "localhost",
              :username => "root",
              :password => "",
              :database => "another_database", 
              :port => 3306,
              :encoding => "utf8"
            )
        rescue ActiveRecord::ConnectionNotEstablished
            @error = "Could not connect to database. The connection was not established"
            could_connect = false
        rescue Mysql2::Error
            @error = "Could not connect to database …

我正试图在3.2.8上使用我的Rails应用程序上的Captainrano上的gem,使用RVM和Rails版本的gemset.

我收到以下错误:无法在任何源中找到rake-10.0.3(Bundler :: GemNotFound)

这是错误的输出(我记录在文件上):

当我使用Rake 10.0.2时,我也得到了错误(我进行了捆绑更新并获得了Rake 10.0.3,我将其留待测试).此外,我注意到捆绑器正在搜索@global,我认为它应该搜索gemset(称为@ r328,位于/home/some_user/.rvm/gems).

.rvmrc(位于项目内部)

我正在按照这个片段在Capistrano中添加Sunspot Solr https://gist.github.com/doitian/1795439并且它有效,但是当我运行cap solr:reindex它显示一个问题(如预期的那样)询问我是否要删除所有索引,所以我回答"是",但终端似乎在等待响应.

这是reindex的代码:

  desc "reindex the whole database"
  task :reindex, :roles => :app do
    stop
    run "rm -rf #{shared_path}/solr/data"
    start
    run "cd #{current_path} && #{rake} RAILS_ENV=#{rails_env} sunspot:solr:reindex" 
  end

这是消息:

  * executing "cd /home/user/rapps/app/current && bundle exec rake RAILS_ENV=production sunspot:solr:reindex"
    servers: ["9.9.9.9"]
    [9.9.9.9] executing command

我在Perl中有一个使用system 命令创建另一个进程的进程,我将它留在内存中并传递一些这样的变量:

my $var1 = "Hello";
my $var1 = "World";
system "./another_process.pl $var1 $var2 &";

但系统命令只返回结果,我需要获取PID.我想做一些像fork的东西.我该怎么办？我怎么能用不同的脚本制作像fork这样的东西？
