Rails 5のエラーがHerokuのRedisに接続中

Question

Redisに接続しているときにHerokuがエラーを返します。私はメッセージングサイトにアクションケーブルを使用していますが、ローカル開発ではFINEが動作します。

私は私production.rbにこれを追加RedisToGo

を使用しています：

config.middleware.use ChatActionCable 
config.web_socket_server_url = "wss://my-app-name-here.herokuapp.com/cable" 
config.action_cable.allowed_request_origins = ['https://my-app-name-here.herokuapp.com', 'http://my-app-name-here.herokuapp.com'] 

ChatActionCableはthisガイドに従いながら、私が追加私のミドルウェアchat_action_cable.rbを指します。ここでそのコードは次のとおりです。

class ChatActionCable < ActionCable::Connection::WebSocket 
    def initialize(app, options={}) 
    @app = app 
end 

    def call(env) 
    if ::WebSocket::Driver.websocket?(env) 
     ActionCable.server.call(env) 
    else 
     @app.call(env) 
    end 
    end 
end 

は私initializers/redis.rb：

uri = URI.parse(ENV["REDISTOGO_URL"] || "redis://localhost:6379/") 
REDIS = Redis.new(:url => uri) 

私cable.yml：ここ

development: 
    adapter: async 

test: 
    adapter: async 

production: &production 
    :adapter: redis 
    :url: redis://redistogo:<my-password-is-here>@barreleye.redistogo.com:11263/ 
    :host: barreleye.redistogo.com 
    :port: 11263 
    :password: <my-password> 
    :inline: true 
    :timeout: 1 

は、Herokuのからの完全なログです：

Answer 1

SOLUTION：rails issue #28362

にここに示したように、この問題は、この問題のピューマ側での作業の人々（puma issue #1189が）で修正を合併しているように見える5.0.1+ Railsの中で確認したバグです更新されたマスターとRails 5.0.3のリリース

UPDATE：私は、バグが実際には5.0.3で修正されたことを、Railsのv5.0.3を実行している新しいプロジェクトに私のプロジェクトを再作成した後に、確認することができます。このアプリケーションは、HerokuでAction CableとWeb Socket機能を正常に実装しています。私は人々がこの記事を見つけて、似たような問題があればこの答えを見てほしい。

Answer 2

あなたのRedisインスタンスで認証に失敗しているか、何らかの理由で届かないようです。 Railsコンソールにログインして手動でデバッグしようとしましたか？

config.middleware.useではなくconfig.middleware.insert_beforeを実行する必要がありますので、bundle exec rake middleware経由でミドルウェアスタックを見ていきます。
