Mongoid scheitert an Rubin 1.9.3

Also spiele ich mit Mongomaterial. Eine neue Heroku-App erstellt, eine Mongolab-Option hinzugefügt, aber jede Mongoid-Methode schlägt fehl.Mongoid scheitert an Rubin 1.9.3

Ich habe gegoogled, und es sieht so aus, als ob dieses Problem mit Ruby vor 1.9.3 war, aber ich habe 1.9.3.

Hier ist die einfachste Fehler Beispiel:

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

Wether ich diese lokal ausgeführt (gegen die mongolab db) oder auf Heroku, bekomme ich die gleiche Art von Fehler:

Was bin ich falsch machen?

AKTUALISIERT hier mein mongoid.yml:

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

Basierend auf dem Stack-Trace es wie der Konstruktor sucht mongo_uri einen Nullwert übergeben wird. Ich würde überprüfen Sie die folgenden in Ihrem mongoid.yml:

es ist an der richtigen Stelle/das Argument load! Punkte an den richtigen Ort
es richtig
konfiguriert ist, wenn es auf alle Umgebungsvariablen bezieht (zB MONGOLAB_URI für die MongoLab Heroku Add-on), dass sie in Ihrer Umgebung gesetzt sind

die entsprechenden Zeilen aus mongo_uri.rb:49, wo die Ausnahme ausgelöst wird:

# 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

ich die Frage mit meiner mongoid.yml Datei aktualisiert. Ich bin mir ziemlich sicher, dass es es liest, weil es sich beschwert, wenn z.B. Es gibt keinen Standard, oder wenn die Umgebungsvariable falsch ist –

, also hatten Sie Recht, lokal war es ein Verbindungsproblem. Und auf dem Server, trotz allem, was mein Gemfile gesagt hat, benutzte er 1.9.1. So führten zwei verschiedene Probleme zu vollkommener Verwirrung. –

Es hat etwas damit zu tun, dass heroku beim Kompilieren von Assets keine Umgebungsvariablen verwendet.

Verwenden Sie dieses Labor von Heroku Feature wird in dieser Frage helfen: https://devcenter.heroku.com/articles/labs-user-env-compile
