如何在数据库中添加 csv 日期

Question

我有包含以下内容的文件：

purchaser name  item description    item price  purchase count  merchant address    merchant name
João Silva  R off R of food   10.0    2   987 Fake St Bob's Pizza
Amy Pond    R of awesome for R    10.0    5   456 Unreal Rd   Tom's Awesome Shop
Marty McFly R Sneakers for R   5.0 1   123 Fake St Sneaker Store Emporium
Snake Plissken  R Sneakers for R   5.0 4   123 Fake St Sneaker Store Emporium

我是这样创建数据库的：

我有以下代码获取数据：

require 'csv'

CSV.foreach('myfile.txt', col_sep: "\t", headers: true).map do |row|
  row.to_h
end

我挤压它时得到以下哈希值：

[{"purchaser name"=>"João Silva", "item description"=>"R off R of food", "item price"=>"10.0", "purchase count"=>"2", "merchant address"=>"987 Fake St", "merchant name"=>"Bob's Pizza"}, {"purchaser name"=>"Amy Pond", "item description"=>"R of awesome for R", "item price"=>"10.0", "purchase count"=>"5", "merchant address"=>"456 Unreal Rd", "merchant name"=>"Tom's Awesome Shop"}, {"purchaser name"=>"Marty McFly", "item description"=>"R Sneakers for R", "item price"=>"5.0", "purchase count"=>"1", "merchant address"=>"123 Fake St", "merchant name"=>"Sneaker Store Emporium"}, {"purchaser name"=>"Snake Plissken", "item description"=>"R Sneakers for R", "item price"=>"5.0", "purchase count"=>"4", "merchant address"=>"123 Fake St", "merchant name"=>"Sneaker Store Emporium"}]

如何将此散列的每一项放入数据库中适当的 table？

Answer 1

CSV.foreach('myfile.txt', col_sep: "\t", headers: true).map do |row|
  records = row.to_h

  # you can set the records as variables:

  purchaser = records["purchaser name"]
  item_description = records["item description"]
  item_price = records["item price"]
  purchase_count = records["purchase count"]
  merchant_address = records["merchant_address"]
  merchant_name = records["merchant name"]

  # now that you have the content as variables do you can whatever you want with them
  # Merchant.where(name: merchant_name), etc...

end
