だから私はモンゴのもので遊んでいます。新しいherokuアプリを作成し、それにmongolabオプションを追加しましたが、すべてのmongoidメソッドが失敗します。

グーグルで調べたところ、この問題は1.9.3より前のRubyで一般的だったようですが、1.9.3を実行しています。

最も単純な失敗例を次に示します。

require 'sinatra'
require 'mongoid'
require 'json'
require "sinatra/reloader" if development?

Mongoid.load!("mongoid.yml")

class Company
    include Mongoid::Document

    field :code, type: String
    field :sector, type: String
    field :share_id, type: Integer
    field :jse_code, type: Integer
end

get '/' do
    "Hello" 
end

get '/company' do
    Company.exists?
end

これをローカルで (mongolab db に対して) 実行しても、heroku で実行しても、同じ種類のエラーが発生します。

私は何を間違っていますか?

UPDATEDは私の mongoid.yml です:

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

スタック トレースに基づいて、コンストラクターにmongo_urinull 値が渡されているようです。私はあなたの次のことを確認しますmongoid.yml

  • 正しい場所にある / への引数がload!正しい場所を指している
  • 正しく構成されています
  • 環境に設定されている環境変数 ( MONGOLAB_URIMongoLab Heroku アドオンなど) を参照している場合

例外がスローされているmongo_uri.rb:49の関連行:

  # Create the new uri from the provided string.
  #
  # @example Create the new uri.
  #   MongoUri.new(uri)
  #
  # @param [ String ] string The uri string.
  #
  # @since 3.0.0
  def initialize(string)
    @match = string.match(URI)
  end

これは、アセットのコンパイル時に heroku が環境変数を使用していないことに関係しています。

Heroku のこのラボ機能を使用すると、この問題に役立ちます: https://devcenter.heroku.com/articles/labs-user-env-compile
