Ruby on rails ActiveRecord:：ConnectionNotEstablished（ActiveRecord:：ConnectionNotEstablished）,ruby-on-rails,mongodb,heroku,mongoid,Ruby On Rails,Mongodb,Heroku,Mongoid,我有一个使用mongodb的Rails应用程序。我想将其部署到Heroku，但出现错误： Using sass-rails (3.2.5) Installing sqlite3 (1.3.5) with native extensions Unfortunately, a fatal error has occurred.

我有一个使用mongodb的Rails应用程序。我想将其部署到Heroku，但出现错误：

       Using sass-rails (3.2.5)
       Installing sqlite3 (1.3.5) with native extensions Unfortunately, a fatal error has occurred.
Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues
so that we can fix it. Thanks!
       /usr/local/lib/ruby/1.9.1/rubygems/installer.rb:483:in `rescue in block in build_extensions':
 ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

我已经在我的Gemfile中对sqlite gem进行了注释：

# gem 'sqlite3'

现在它在heroku上正确部署，但在使用应用程序时出现错误：

ActiveRecord::ConnectionNotEstablished (ActiveRecord::ConnectionNotEstablished):
  activerecord (3.2.1) lib/active_record/connection_adapters/abstract/connection_pool.rb:374:in `retrieve_connection'

我如何解决我的问题

已更新

我在application.rb中包含了下一行，因此它看起来像：

require 'rails/all'

require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "rails/test_unit/railtie"

在config/application.rb中，您需要对ActiveRecord的要求进行注释：

# require "active_record/railtie"

如果您需要所有rails by

require'rails/all'

您需要按所需的所有railtie将其拆分。举例来说，在我的应用程序中，使用Mongoid而不是ActiveRecord而不是ActionResources，我只有“rails/all”来代替：

# require 'rails/all'
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"

你在Application.rb中删除了ActiveRecord的要求吗？我已经更新了我的答案。删除活动记录是否足够？如果您需要活动记录？您需要删除此要求您是否删除了应用程序中对ActiveRecord的要求。rb？我已更新了我的答案。删除活动记录是否足够？如果您需要活动记录？你需要删除此要求谢谢它对我有帮助。我评论了require“active_record/railtie”和environments/*中的一些行。RB您也需要评论rails/的要求，因为您的回答中没有这样做。我用这些信息更新我的答案，谢谢它帮助了我。我评论了require“active_record/railtie”和environments/*中的一些行。RB您也需要评论rails/的要求，因为您的回答中没有这样做。我用这些信息更新我的答案
