ruby-on-rails - 遇到错误后使 Ruby/Rails 继续方法

Question

def checkdomains
  @domains = Domain.all

  #@domains.where(:confirmed => "yes").each do |f|
  @domains.each do |f|
    r = Whois.whois(f.domain)
    if r.available? == true
      EmailNotify.notify_email(f).deliver
    end
  end
end

此方法在遇到无效 url 时崩溃(whois gem 给出错误)，并且不会继续检查其余域。有什么方法可以让它继续检查其余域，即使它在一个域上崩溃了？至少在我能够解决每个域的钓鱼问题之前是这样。

Answer 1

  @domains.each do |f|
    begin
      r = Whois.whois(f.domain)
      if r.available? == true
        EmailNotify.notify_email(f).deliver
      end
    rescue Exception => e
      puts "Error #{e}"
      next   # <= This is what you were looking for
    end
  end
