將散列的內容保存到模型

Question

慢慢地到達那裏，我試圖實現。我通過屏幕抓取抓取數據，並希望將數據保存到我的模型中，我有兩列，home_team和away_team。到目前爲止，我抓住了數據。

FIXTURE_URL = "http://www.bbc.co.uk/sport/football/premier-league/fixtures" 

def get_fixtures # Get me all Home and away Teams 
doc = Nokogiri::HTML(open(FIXTURE_URL)) 
home_team = doc.css(".team-home.teams").map {|h| h.text.strip } 
away_team = doc.css(".team-away.teams").map {|a| a.text.strip } 
#team_clean = Hash[:home_team => home_team, :away_team => away_team] 
#team_clean = Hash[:team_clean => [Hash[:home_team => home_team, :away_team => away_team]]] 
end 

我已經散列了獲取數據到一個哈希的方式有兩種，一種是散，另一個是散列中的散列，我不知道我需要哪一個（如果有的話？）

所以，如果我想保存從我HOME_TEAM接收到的數據我運行耙子任務來完成

def update_fixtures #rake task method 
Fixture.destroy_all 
get_fixtures.each {|home| Fixture.create(:home_team => home)} 
end 

我想要實現的是能夠節省HOME_TEAM和AWAY_TEAM在同一時間。我是否需要訪問哈希中的數據，如果是這樣的話？這裏有點失落，但是這是我第一次嘗試這種

任何幫助表示讚賞

Answer 1

試試這個，

FIXTURE_URL = "http://www.bbc.co.uk/sport/football/premier-league/fixtures" 

def get_fixtures # Get me all Home and away Teams 
    doc = Nokogiri::HTML(open(FIXTURE_URL)) 
    matches = doc.css('tr.preview') 
    matches.each do |match| 
    home_team = match.css('.team-home').text.strip 
    away_team = match.css('.team-away').text.strip 
    Fixture.create!(home_team: home_team, away_team: away_team) 
    end 
end 

這將遍歷匹配，並與遠及家庭創建一個新的Fixture每場比賽的球隊。

編輯：

新增.text.strip

編輯2：

這應該讓你的日期也

FIXTURE_URL = "http://www.bbc.co.uk/sport/football/premier-league/fixtures" 

def get_fixtures # Get me all Home and away Teams 
    doc = Nokogiri::HTML(open(FIXTURE_URL)) 
    days = doc.css('#fixtures-data h2').each do |h2_tag| 
    date = Date.parse(h2_tag.text.strip) 
    matches = h2_tag.xpath('following-sibling::*[1]').css('tr.preview') 
    matches.each do |match| 
     home_team = match.css('.team-home').text.strip 
     away_team = match.css('.team-away').text.strip 
     Fixture.create!(home_team: home_team, away_team: away_team, date: date) 
    end 
    end 
end 

這是一個有點比以前更復雜因爲它必須使用一些XPath來調用h2標籤之後的下一個HTML元素包含日期。

它通過循環在div#fixtures-data HTML所有h2 html標籤則每個h2後抓住table標籤下方/。
