將字符串拆分爲兩個單獨的屬性ruby

Question

我正在執行一個屏幕抓取以獲得足球結果，並將得分作爲一個字符串，例如2-2。我會非常想有是有成績分成home_score然後away_score其保存到我的模型爲每個結果

目前我做這

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 

從一些進一步的閱讀中，我可以看到你可以使用.split方法

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

所以，我會能夠做到這一點

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

但如何融入我的當前設置是什麼扔我，那就算我的邏輯是正確的，我還是想home_score和away_score提前分配到正確的結果

感謝所有幫助

編輯

好了，到目前爲止，答案是不，我不能做這種方式，運行rake任務後，我得到一個錯誤

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

的原因。每個不工作是因爲每一個爲字符串的方法在RU到1.8，它在Ruby 1.9中被刪除。我曾嘗試each_char，現在節省了一定的成果，而不是其他，並且當它保存home_score和away_score分配不正確

由於@seph指出各是沒有必要，如果它可以幫助別人我的最終任務看起來像這樣

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

無需爲每個。這樣做：

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