Rails 6 while 运行 sidekiq 数据库配置没有指定适配器

Question

最近我们开始将我们的代码库从 rails 5 迁移到 rails 6。除了 sidekiq 之外，一切似乎都运行良好。每当我们在生产模式下尝试运行 sidekiq 时，它总是会抛出错误 数据库配置未指定适配器 。我很确定我们在 database.yml 中提到了一个适配器。有人可以帮忙解决这个问题吗？

供参考

Rails6.0.3.4

Sidekiq 6.1.2

Ruby 2.7.1p83

databsae.yml 文件

default: &default
  adapter: postgresql
  pool: <%= ENV['DATABASE_POOL'] %>
  timeout: 5000
  database: anajmandi
  
development:
  primary:
    <<: *default
    url: <%= ENV['DATABASE_URL'] %>
    multidb:
      fallback: true
  follower: 
    <<: *default
    url: <%= ENV['DATABASE_SLAVE_URL'] %>
    replica: true
    multidb:
      fallback: true

test:
  <<: *default
  database: db/test.sqlite3

production:
  primary:
    <<: *default
    url: <%= ENV['DATABASE_URL'] %>
    multidb:
      fallback: true
  follower: 
    <<: *default
    url: <%= ENV['DATABASE_SLAVE_URL'] %>
    replica: true
    multidb:
      fallback: true

和sidekiq.rb文件

# typed: strict
if Rails.env.production?
  # three unicorns = 3 connections
  Sidekiq.configure_client do |config|
    config.redis = { :size => 1 }
  end

  Sidekiq.configure_server do |config|
    config.redis = { url: ENV['REDIS_URL'], size: 22 }

    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]
        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

这是运行ning 命令 bundle exec sidekiq -e production -C config/sidekiq.yml

上的错误堆栈跟踪

Answer 1

这里我使用的是 3 层配置，因此没有正确定义 3 层配置的初始值设定项。如果我们 select 通过环境变量进行配置，那么我们将得到两个，主要的和从属的。 Rails 不知道访问哪一个，所以应用程序必须 select 正确的。

将config = Rails.application.config.database_configuration[Rails.env]改为

self.configurations = Rails.application.config.database_configuration

config = configurations.configs_for(env_name: Rails.env, spec_name: "primary").config
