使用每个循环通过哈希（1 vs More）

标签： ruby-on-rails hash each

我有一个正在解析并发送到我的函数的哈希。

我遇到的问题是当我发送1个帖子时出错，因为它解析了每个属性并将每个属性作为帖子发送。

如果我发送超过1个帖子，它会正确解析。并将每篇文章作为帖子发送

def self.build_post(posts, type, user_id)
    posted_loads = 0
    posted_trucks = 0
    puts posts
    puts posts["#{type.downcase}"].count
    posts["#{type.downcase}"].each do |post|
      post = Hash[*post.flatten]
      puts post 
      record = build_record(post, user_id, type)
    ----- SOME MORE STUFF ----
end

当我只发送1个加载

时

控制台显示：

  {"load"=>{"tracking_number"=>"493266", "origin"=>{"city"=>"BUENA PARK", "state"=>"CA", "postcode"=>nil, "county"=>nil, "country"=>nil, "latitude"=>"NaN", "longitude"=>"NaN", "date_start"=>{"year"=>"2009", "month"=>"06", "day"=>"04", "hour"=>"12", "minute"=>"00"}, "date_end"=>{"year"=>nil, "month"=>nil, "day"=>nil, "hour"=>nil, "minute"=>nil}}, "destination"=>{"city"=>"CORAL SPRINGS", "state"=>"FL", "postcode"=>nil, "county"=>nil, "country"=>nil, "latitude"=>"NaN", "longitude"=>"NaN", "date_start"=>{"year"=>"2009", "month"=>"06", "day"=>"04", "hour"=>"12", "minute"=>"00"}, "date_end"=>{"year"=>nil, "month"=>nil, "day"=>nil, "hour"=>nil, "minute"=>nil}}, "equipment"=>{"v"=>nil}, "loadsize"=>{"fullload"=>"true", "length"=>"53", "width"=>nil, "height"=>nil, "weight"=>"09"}, "load_count"=>"1", "stops"=>"0", "distance"=>"2600", "rate"=>"0.00", "comment"=>"DRY VAN"}}
  10
  {"tracking_number"=>"493266"}

当我发送2个或更多负载时（它完美地运行）

控制台显示：

  {"load"=>[{"tracking_number"=>"493266", "origin"=>{"city"=>"BUENA PARK", "state"=>"CA", "postcode"=>nil, "county"=>nil, "country"=>nil, "latitude"=>"NaN", "longitude"=>"NaN", "date_start"=>{"year"=>"2009", "month"=>"06", "day"=>"04", "hour"=>"12", "minute"=>"00"}, "date_end"=>{"year"=>nil, "month"=>nil, "day"=>nil, "hour"=>nil, "minute"=>nil}}, "destination"=>{"city"=>"CORAL SPRINGS", "state"=>"FL", "postcode"=>nil, "county"=>nil, "country"=>nil, "latitude"=>"NaN", "longitude"=>"NaN", "date_start"=>{"year"=>"2009", "month"=>"06", "day"=>"04", "hour"=>"12", "minute"=>"00"}, "date_end"=>{"year"=>nil, "month"=>nil, "day"=>nil, "hour"=>nil, "minute"=>nil}}, "equipment"=>{"v"=>nil}, "loadsize"=>{"fullload"=>"true", "length"=>"53", "width"=>nil, "height"=>nil, "weight"=>"09"}, "load_count"=>"1", "stops"=>"0", "distance"=>"2600", "rate"=>"0.00", "comment"=>"DRY VAN"}, {"tracking_number"=>"493266", "origin"=>{"city"=>"BUENA PARK", "state"=>"CA", "postcode"=>nil, "county"=>nil, "country"=>nil, "latitude"=>"NaN", "longitude"=>"NaN", "date_start"=>{"year"=>"2009", "month"=>"06", "day"=>"04", "hour"=>"12", "minute"=>"00"}, "date_end"=>{"year"=>nil, "month"=>nil, "day"=>nil, "hour"=>nil, "minute"=>nil}}, "destination"=>{"city"=>"CORAL SPRINGS", "state"=>"FL", "postcode"=>nil, "county"=>nil, "country"=>nil, "latitude"=>"NaN", "longitude"=>"NaN", "date_start"=>{"year"=>"2009", "month"=>"06", "day"=>"04", "hour"=>"12", "minute"=>"00"}, "date_end"=>{"year"=>nil, "month"=>nil, "day"=>nil, "hour"=>nil, "minute"=>nil}}, "equipment"=>{"v"=>nil}, "loadsize"=>{"fullload"=>"true", "length"=>"53", "width"=>nil, "height"=>nil, "weight"=>"09"}, "load_count"=>"1", "stops"=>"0", "distance"=>"2600", "rate"=>"0.00", "comment"=>"DRY VAN"}]}

如果有倍数，看起来它正在将它放入一个哈希数组中。

这是我的控制器

def loads
    hash = Hash.from_xml(request.body.read)
    account = hash["PELoadPostings"]["PostingAccount"]
    post = hash["PELoadPostings"]["PostLoads"]
    post1 = hash["PELoadPostings"]["RemoveLoads"]
    if post
      message1 = PostEverywhereXml.post_loads(post, account)
    end
    if post1
      message1 = PostEverywhereXml.remove_loads(post1, account)
    end
    message = message1
    message ||= "Error: No loads in file"
    render :text => message
  end

在

中发送样本加载数据
