铁路只在一些请求中使用主动记录
原标题:Making Rails use ActiveRecord for only some requests

我有铁路申请,绝大多数要求都不会以任何方式使用主动记录。 如果其余的申请在无法提供MySQL时无缝地工作,那将是空洞的。 然而,根据每项要求,“积极记录”似乎都叫了。 这意味着,每当真正只有使用积极核查手段时,每个终点都会中断。 我怎么能够把事情混为一谈,这样,如果没有我的SQL,那些不需要积极核查的行动就会失败?

消除饥饿!

class ActiveRecord::Base
  def self.verify_active_connections!
    begin
       super
    rescue
      puts "Do something"
    end
   end
 end

Probably not the best idea to just do a blanket begin/rescue but you get the point. For more information check this question out: "MySQL server has gone away" with Ruby on Rails
