Question

所以我得到连接失败，这显示了这个错误：

rake aborted!

Faraday::ConnectionFailed: execution expired

我怎样才能避免我的rake任务爆炸，再试一次或跳到下一行？

继承我的佣金任务

require 'nokogiri'
require 'open-uri'
namespace :webtask do
  task populate: :environment do
    Event.all.each do |row|
      tweventname = I18n.transliterate(row.eventname)
      url = url here
      doc = Nokogiri::HTML(open(url))
      doc.css('.table__row--event').each do |tablerow|
        table = tablerow.css('.table__cell__body--location').css('h4').text
        next unless table == row.eventvenuename
          tablerow.css('.table__cell__body--availability').each do |button|
            buttonurl = button.css('a')[0]['href']
            if buttonurl.include? '/checkout/external'
              else
            row.update(url: buttonurl)
          end
          end
      end
    end
  end
end

也许你需要一个标准的救援块。

require 'nokogiri'
require 'open-uri'
namespace :webtask do
  task populate: :environment do
     Event.all.each do |row|
      begin #Tells rescue where to jump 
      tweventname = I18n.transliterate(row.eventname)
      url = url here
      doc = Nokogiri::HTML(open(url))
      doc.css('.table__row--event').each do |tablerow|
        table = tablerow.css('.table__cell__body--location').css('h4').text
        next unless table == row.eventvenuename
          tablerow.css('.table__cell__body--availability').each do |button|
            buttonurl = button.css('a')[0]['href']
            if buttonurl.include? '/checkout/external'
              else
            row.update(url: buttonurl)
          end
          end
      end
    end
   rescue Faraday::ConnectionFailed
     next
   end
  end
end
