将散列的内容保存到模型

Question

慢慢地到达那里，我试图实现。我通过屏幕抓取抓取数据，并希望将数据保存到我的模型中，我有两列，home_team和away_team。到目前为止，我抓住了数据。

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 

我已经散列了获取数据到一个哈希的方式有两种，一种是散，另一个是散列中的散列，我不知道我需要哪一个（如果有的话？）

所以，如果我想保存从我HOME_TEAM接收到的数据我运行耙子任务来完成

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

我想要实现的是能够节省HOME_TEAM和AWAY_TEAM在同一时间。我是否需要访问哈希中的数据，如果是这样的话？这里有点失落，但是这是我第一次尝试这种

任何帮助表示赞赏

Answer 1

试试这个，

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 

这将遍历匹配，并与远及家庭创建一个新的Fixture每场比赛的球队。

编辑：

新增.text.strip

这应该让你的日期也

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 

这是一个有点比以前更复杂因为它必须使用一些XPath来调用h2标签之后的下一个HTML元素包含日期。

它通过循环在div#fixtures-data HTML所有h2 html标签则每个h2后抓住table标签下方/。
