我正在使用 Rails 6.1.4.4、Octoshark 0.3.0，刚刚升级到 Ruby 3.0.2。 现在启动 Rails 控制台时，我得到

我在 config/initializers/octoshark.rb 中配置了这个

CONN_MANAGER = Octoshark::ConnectionPoolsManager.new({
  readonly: Rails.application.config.database_configuration['readonly'],
  third_party_readonly: {
    adapter: 'sqlserver',
    username: APP_CONFIG.third_party_read_secondary[Rails.env].username,
    password: APP_CONFIG.third_party_read_secondary[Rails.env].password,
    host: APP_CONFIG.third_party_read_secondary[Rails.env].host,
    database: APP_CONFIG.third_party_read_secondary[Rails.env].database
  }
})

class ActiveRecord::Base
  def self.connection
    CONN_MANAGER.current_or_default_connection
  end
end

不确定我需要对上述或其他升级进行哪些其他更改才能正确配置连接池并正确加载内容。

这与关键字 arguments 在 ruby 3.0 中的处理方式以及 octoshark如何将其 arguments 传递给 .establish_connection octoshark .establish_connection
因此，我认为您可以对 gem 方法进行猴子修补或使用 fork，其中参数显式传递给 active-record 方法：

module Octoshark
  module ConnectionHandler
    def establish_connection(config, **parameters)
      Octoshark::ConnectionPoolsManager.reset_connection_managers!
      super(config, **parameters)
    end
  end
end
