将CSV文件写入yaml文件？

Question

想知道是否有人可以帮我输出这个yaml文件？

由于目前它只写入返回到yaml文件的最后一个数组。

 require 'csv' 
     require 'yaml' 
      #fp = File.open("vatsim-row.txt") 

CSV.foreach("vatsim-data.txt", :col_sep =>':', :row_sep =>:auto, :quote_char => ":") do |row| 

if (row[3] == "PILOT") and (row[13]=="EIDW" or row[13]=="EICK" or row[13]=="EINN" or row[13]=="EIKN" or row[13]=="EIDL" or row[13]=="EICM" or row[13]=="EIKY" or row[13]=="EISG" or row[13]=="EIWF" or row[13]=="EIWT" or row[11]=="EIDW" or row[11]=="EICK" or row[11]=="EINN" or row[11]=="EIKN" or row[11]=="EIDL" or row[11]=="EICM" or row[11]=="EIKY" or row[11]=="EISG" or row[11]=="EIWF" or row[11]=="EIWT") 

p row 

p row.count 

File.open("pilots.yml", "w") {|f| f.write(row.to_yaml) } 

elsif row[3] == "ATC" and (row[0].slice(0, 3) == "EGC" or row[0].slice(0, 3) == "EID" or row[0].slice(0, 3) == "EIC" or row[0].slice(0, 3) == "EIN" or row[0].slice(0, 3) == "EIK" or row[0].slice(0, 3) == "EIS" or row[0].slice(0, 3) == "EIW" or row[0].slice(0, 3) == "EIM") 

       p row 
       p row.count 
      end 

     end 

排序输出我正在寻找在YAML文件：

如果任何人都可以在方向指向我，将是巨大的！

您需要打开文件进行追加。使用模式w打开一个文件会将其截短为0，这样您就可以在循环的每次迭代中覆盖它。

使用此：

File.open("pilots.yml", "a") {|f| f.write(row.to_yaml) } 

更重要的是，保留文件打开追加通过了方案，而不是重复打开和关闭它。那么你可能会要截断文件：

File.open("pilots.yml", "w") do |f| 
    CSV.foreach("vatsim-data.txt", :col_sep =>':', :row_sep =>:auto, :quote_char => ":") do |row| 
    # ... 

    f.write(row.to_yaml) 

    # ... 
    end 
end
