我正在使用下面的一段代码将我的Hashmap写入带有标题的csv文件。但是，我注意到第一个数据行在文件中不可用。我可以准确地标题和所有其他行写入csv将省略第一行
def self.execute_auto_pg_debtors pg_debtors_dt_list
partition_key = Date.today.prev_day.prev_day.strftime "%Y%m%d"
csvfilename = "PG_Debtors_" + partition_key + ".CSV"
pg_debtors_dt_batch = Array.new
rowid = 0
pg_debtors_dt_list.each { |x|
pg_debtors_details = Hash.new
pg_debtors_details["Store_Order_Id"] = x['Store_Order_Id']
pg_debtors_details["Transaction_Id"] = x['Transaction_Id']
pg_debtors_details["Gateway_Payment_Id"] = x['Gateway_Payment_Id']
pg_debtors_details["PPS_Id"] = x['PPS_Id']
pg_debtors_details["Event_Type"] = x['Event_Type']
pg_debtors_details["Event_Date"] = x['Event_Date']
pg_debtors_details["Gateway_Name"] = x['Gateway_Name']
pg_debtors_details["Open_Amount"] = "%f" % x['Open_Amount']
pg_debtors_details["Invoice_No"] = x['Invoice_No']
pg_debtors_dt_batch << pg_debtors_details
rowid += 1
if rowid == 1
CSV.open(csvfilename, "w") do |csv|
csv << pg_debtors_details.keys# adding header row (column labels)
end
else
CSV.open(csvfilename, "a") do |csv|
csv << pg_debtors_details.values# of if/else inside hsh
end# of hsh's (rows)
end# of csv open
}
return pg_debtors_dt_batch
end
请帮助。
