Ruby on rails 工人未初始化Heroku+；Sidekiq+；博士后&x2B；再悬浮

我正在尝试使用以下命令在Heroku worker中初始化Sidekiq：

if Rails.env.production?

  Sidekiq.configure_client do |config|
    config.redis = { url: ENV['REDISCLOUD_URL'], size: 2 }
  end

  Sidekiq.configure_server do |config|
    config.redis = { url: ENV['REDISCLOUD_URL'], size: 10 }

    Rails.application.config.after_initialize do
      Rails.logger.info("DB Connection Pool size for Sidekiq Server before disconnect is: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      ActiveRecord::Base.connection_pool.disconnect!

      ActiveSupport.on_load(:active_record) do
        config = Rails.application.config.database_configuration[Rails.env]
        config['reaping_frequency'] = ENV['DATABASE_REAP_FREQ'] || 10 # seconds
        # config['pool'] = ENV['WORKER_DB_POOL_SIZE'] || Sidekiq.options[:concurrency]
        config['pool'] = 8
        ActiveRecord::Base.establish_connection(config)

        Rails.logger.info("DB Connection Pool size for Sidekiq Server is now: #{ActiveRecord::Base.connection.pool.instance_variable_get('@size')}")
      end
    end
  end

end  

但我的日志中有以下内容：

有人知道怎么回事吗？

它正在本地主机上寻找Postgres:5432

在Heroku上运行Sidekiq时，我也遇到了同样的问题。我通过在database.yml中的

production:

下面添加

url:

来修复它
