とあるサイトを思い立って、Rails 4.0 にアップグレードしました。 久しぶりすぎて、MongoDB (MongoHQ) を使っていることを忘れていたため、かなり軽い気持ちではじめましたが、これがなかなか。。

Rails 3.2.12を4.0.0にアップグレードした - 平凡なエンジニアの独り言

Installation in Rails 3 // MongoMapper

この辺を参考にして。

一般的なRailsのアップグレードで開発環境を立ち上げる

rake rails:update したり、config/routes.rb の match をpost/get に変更したり。

MongoMapperの対応

開発環境を立ち上げてみると、MongoMapperのコネクションエラー。 調べてみると、 stable なRails4 版はまだないんですね。。

MongoMapperのバージョンを指定

ベータ版を指定します。

gem 'mongo_mapper', :git => "git://github.com/mongomapper/mongomapper.git", :tag => "v0.13.0.beta2"

active_recordをはずす

config/application.rb の冒頭でrails 全てではなく、active_recordをのぞいてロードするように変更

require File.expand_path('../boot', __FILE__) require "action_controller/railtie" require "action_mailer/railtie" #require "active_resource/railtie" require "sprockets/railtie" require "rails/test_unit/railtie" require "image_size" require "open-uri"

config/environments/development.rb にもactive_record の設定をしている箇所があるので、変更

# Raise an error on page load if there are pending migrations # config.active_record.migration_error = :page_load

mongo.rb を削除

自動的に接続するように変更になったらしい。

$ rm config/initializers/mongo.rb

mongo.yml をURI表記に変更

データベース名とかユーザー名を個別に指定する方法だと接続できませんでした。謎。

development: uri: mongodb://:@.mongohq.com:/ # database: # host: .mongohq.com # port: # user: # password:

で、クラッシュ

開発環境で立ち上がったので、本番環境にリリース。ってことでHeroku に push しました。

ほほう。。

$ heroku logs --app=xxxxx 2014-02-16T02:36:24.812184+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/articles/4fe1753f5e63882228000072/weather_chart/month host=vn.dash-news.com request_id=7d2fa4b5-e48d-463f-a1a4-3e1855cd6058 fwd="66.249.64.27" dyno= connect= service= status=503 bytes= 2014-02-16T02:35:45.610615+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/a/4fd0c22a5e63887908000068/month host=vn.dash-news.com request_id=66b5620e-fc6c-4616-8815-6c3384ce207f fwd="157.55.34.99" dyno= connect= service= status=503 bytes= ....

MongoMapperの接続がうまく行ってないんだろうなーとか思いながら、production.rb を確認したり、「mongomapper rails4 app crashed」で検索したり。 結局わからず、眠くなったので睡眠。

そして原因は。。

悶々とした一晩を過ごし、 rails c production を"やっと"、思いついた。。

$ rails c production /Users/yosiyuki/.rvm/gems/ruby-2.0.0-p353/gems/activemodel-4.0.2/lib/active_model/validations/format.rb:46:in `check_options_validity': The provided regular expression is using multiline anchors (^ or $), which may present a security risk.

ArgumentError ... ^ と $ はいけませんよ。と。

修正したら本番環境立ち上がった。。

Testing As it turns out, DatabaseCleaner requires that an ORM (object relational mapper) is identified when it is run. It just so happens, that ActiveRecord is the default ORM, which is why I've never had to explicitly state it! Naturally, using MongoID had me scratching my head. Here are the changes that got things up and running:

Files where DatabaseCleaner is configured: Rspec - spec/spec_helper.rb Cucumber - features/support/env.rb

Code for MongoID:

DatabaseCleaner[:mongoid].strategy = :truncation

Code for ActiveRecord:

DatabaseCleaner.strategy = :truncation

Deploying Deploying to Heroku using the MongoHQ cloud server was a little tricky. In order to "migrate", or copy local database information to the cloud, specific database users and passwords needed to be set up. PostgreSQL and SQLite3 don't require any sort of authentication to get things up and running, so it was an extra step.

MongoHQ, a database hosting service provider has been affected by a major security breach on Monday which gave hackers the opportunity to simply steal private data like email addresses, hashed password data and many other account information. The MongoHQ co-founder, Jason McCay set the orders straight via blog post and clarified the issue: „On October […]

Alex Williams for TechCrunch:

MongoHQ has raised $6 million from Trinity Ventures and a host of investors for its database service for developers. The company will use the funds to expand its public cloud offering and improve its management tools for MongoDB, the popular NoSQL database.

Undeniably there’s a lot of demand for MongoDB. 10gen is also growing fast.

But how safe is to build a business around a product that is not in your control?

                             Was hacking around with this code a few weeks ago and wanted to finish it up and get it out for some feedback.

If you haven't heard, mongodb is the hottest thing to come around for quite some time. It also looks like it is  a skill that is in high demand.

I started converting this module which is based on code from MongoHQ, but eventually I converted the code base so it will work with Mongolab. Both of these vendors provide hosting for you mongodb needs, so check them out and see what works for you.
