将字符串拆分为两个单独的属性ruby

Question

我正在执行一个屏幕抓取以获得足球结果，并将得分作为一个字符串，例如2-2。我会非常想有是有成绩分成home_score然后away_score其保存到我的模型为每个结果

目前我做这

def get_results # Get me all results 
doc = Nokogiri::HTML(open(RESULTS_URL)) 
days = doc.css('.table-header').each do |h2_tag| 
date = Date.parse(h2_tag.text.strip).to_date 
    matches = h2_tag.xpath('following-sibling::*[1]').css('tr.report') 
    matches.each do |match| 
    home_team = match.css('.team-home').text.strip 
    away_team = match.css('.team-away').text.strip 
    score = match.css('.score').text.strip 
    Result.create!(home_team: home_team, away_team: away_team, score: score, fixture_date: date) 
    end 
end 

从一些进一步的阅读中，我可以看到你可以使用.split方法

.split("x").map(&:to_i) 

所以，我会能够做到这一点

score.each do |s| 
home_score, away_score = s.split("-").map(&:to_i) 
Result.create!(home_score: home_score, away_score: away_score) 
end 

但如何融入我的当前设置是什么扔我，那就算我的逻辑是正确的，我还是想home_score和away_score提前分配到正确的结果

感谢所有帮助

编辑

好了，到目前为止，答案是不，我不能做这种方式，运行rake任务后，我得到一个错误

undefined method `each' for "1-2":String 

的原因。每个不工作是因为每一个为字符串的方法在RU到1.8，它在Ruby 1.9中被删除。我曾尝试each_char，现在节省了一定的成果，而不是其他，并且当它保存home_score和away_score分配不正确

由于@seph指出各是没有必要，如果它可以帮助别人我的最终任务看起来像这样

def get_results # Get me all results 
    doc = Nokogiri::HTML(open(RESULTS_URL)) 
    days = doc.css('.table-header').each do |h2_tag| 
    date = Date.parse(h2_tag.text.strip).to_date 
    matches = h2_tag.xpath('following-sibling::*[1]').css('tr.report') 
    matches.each do |match| 
    home_team = match.css('.team-home').text.strip 
    away_team = match.css('.team-away').text.strip 
    score = match.css('.score').text.strip 
    home_score, away_score = score.split("-").map(&:to_i) 
    Result.create!(home_team: home_team, away_team: away_team, fixture_date: date, home_score: home_score, away_score: away_score) 

    end 
    end 
    end

无需为每个。这样做：

home_score, away_score = score.split("-").map(&:to_i)
