MongoidDB，Heroku，設備，MongoHQ和Rails的MongoDB錯誤

Question

我正在致力於a simple app，目前部署到heroku - 它使用mongoid，設備，並且可以非常容易地在localhost中創建用戶登錄，但不能在生產中Heroku的。您可以嘗試創建一個帳戶，並在提交後出現錯誤。

我認爲我的生產mongoid.yml需要改變，但我不知道如何。

我heroku config有以下幾點：

=== Config Vars for bookfoo 
DATABASE_URL:  postgres://jeibucpexp:bVZzGaGPUeGylwmA7dyE@ec2-107-20-186-97.compute-1.amazonaws.com/jeibucpexp 
GEM_PATH:   vendor/bundle/ruby/1.9.1 
LANG:    en_US.UTF-8 
MONGOHQ_URL:   mongodb://heroku:14bc6d476e6449c952d6350b07e89643@alex.mongohq.com:10065/app6153931 
MONGOLAB_URI:  mongodb://heroku_app6153931:og03dk0hdrj7r8lsit51k6ah9n@ds037097-a.mongolab.com:37097/heroku_app6153931 
PATH:    bin:vendor/bundle/ruby/1.9.1/bin:/usr/local/bin:/usr/bin:/bin 
RACK_ENV:   production 
RAILS_ENV:   production 
SHARED_DATABASE_URL: postgres://jeibucpexp:bVZzGaGPUeGylwmA7dyE@ec2-107-20-186-97.compute-1.amazonaws.com/jeibucpexp 

mongoid.yml具有的建議在Heroku的以下內容：

development: 
    sessions: 
    default: 
     database: bookfoo_app_development 
     hosts: 
     - localhost:27017 
     options: 
     consistency: :strong 
    options: 
test: 
    sessions: 
    default: 
     database: bookfoo_app_test 
     hosts: 
     - localhost:27017 
     options: 
     consistency: :strong 
production: 
    sessions: 
    default: 
     uri: <%= ENV['MONGOHQ_URL'] %> 
    options: 
     skip_version_check: true 
     safe: true 

我的Gemfile有以下幾點：

source 'https://rubygems.org' 

gem 'rails', '3.2.3' 

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

group :test do 
    gem 'database_cleaner' 
    gem 'mongoid-rspec' 
    gem 'factory_girl_rails' 
    gem 'email_spec' 
    gem 'capybara' 
    gem 'launchy' 
end 

group :production do 
    gem 'thin' 
end 

group :assets do 
    gem 'sass-rails', '~> 3.2.3' 
    gem 'coffee-rails', '~> 3.2.1' 
    gem 'uglifier', '>= 1.0.3' 
end 

gem 'jquery-rails' 
gem "mongoid", :git => "git://github.com/mongoid/mongoid.git" 
gem "bson_ext" 
gem "devise" 

git push heroku master後它給了我以下提示：

There is a configuration error with the current mongoid.yml. 
     Problem: 
     No database provided for session configuration: :options. 
     Summary: 
     Each session configuration must provide a database so Mongoid knows where the default database to persist to. What was provided was: {"skip_version_check"=>true, "safe"=>true}. 
     Resolution: 
     If configuring via a mongoid.yml, ensure that within your :options section a :database value for the session's default database is defined. 
     Example: 
     \_\_development: 
     \_\_\_\_sessions: 
     \_\_\_\_\_\_options: 
     \_\_\_\_\_\_\_\_database: my_app_db 
     \_\_\_\_\_\_\_\_hosts: 
     \_\_\_\_\_\_\_\_\_\_- localhost:27017 

Answer 1

mongoid.yml應該是這樣（我的縮進是錯誤的）：

production: 
    sessions: 
    default: 
     uri: <%= ENV['MONGOHQ_URL'] %> 
     options: 
     skip_version_check: true 
     safe: true
