從使用Heroku的github克隆的rails應用程序訪問問題

Question

我從GitHub克隆了一個項目，現在我無法在本地運行它。

我得到這個錯誤在瀏覽器：

Moped::Errors::ConnectionFailure at/
Could not connect to any secondary or primary nodes for replica set <Moped::Cluster nodes=[<Moped::Node resolved_address="127.0.0.1:27017">]> 

，並在終端我得到這個錯誤，當我鍵入任何Heroku的命令：

$ heroku info 
! You do not have access to the app disrupt. 

我是新來的Rails那麼簡單指導/建議會很好。

這就是我mongoid.yml文件

development: 
    # Configure available database sessions. (required) 
    sessions: 
# Defines the default session. (required) 
default: 
    # Defines the name of the default database that Mongoid can connect to.

    # How many times Moped should attempt to retry an operation after

test: 
    sessions: 
default: 
    database: disrupt_test 
    hosts: 
    - localhost:27017 
    options:

    # In the test environment we lower the retries and retry interval to 
    # low amounts for fast failures. 
    max_retries: 1 
    retry_interval: 0 


production: 
    sessions: 
default: 
    uri: <%= ENV['MONGOHQ_URL'] %>

你是不是爲production環境（或其他）正確設置uri內。

yml文件格式不會知道您的頂級密鑰（它會看到默認值：和生產：作爲單獨的鍵，因爲它們沒有嵌套）之間的區別。

假設你正在使用在Heroku MongoHQ 3.x中，嘗試改變...

production: 
    sessions: 
default: 
    uri: <%= ENV['MONGOHQ_URL'] %> 

...到...

production: 
    sessions: 
    default: 
     uri: <%= ENV['MONGOHQ_URL'] %> 

在Heroku MongoHQ docs

應該有更多的信息
