Ruby on rails 在.yml文件中将字符串拆分为两行

我需要在一个文件.yml中将一个字符串拆分为两行或三行。问题是，如果我尝试将最后一个字段描述拆分为两行，则会触发错误， 因此，我只留下一行

one:
  id: 1
  bus_company_id: 2
  seat_type_id:   1
  description:    Butacas 120º de inclinación,
                  calefacción y aire acondicionado, música funcional y video.

two:
  id: 2
  bus_company_id: 2
  seat_type_id:   2
  description:    Butacas de cuero y paño 120º de reclinación,  bandeja de apoyo
   para pies, calefacción y aire acondicionado, música funcional y video.

three:
  id: 3  
  bus_company_id: 2
  seat_type_id:   4
  description:    Butacas extra ancho de cuero y paño 150º de reclinación, bandeja de apoyo para pies,
   desayuno, almohada y frazada, sistema de DVD y MP3.

four:
  id: 4 
  bus_company_id: 2
  seat_type_id:   5
  description:    Butacas de cuero 180º reclinación, bandeja de apoyo para pies de 180º de reclinación, cortina divisoria, almohada y frazadas sonido sourround, sistema de DVD y MP3, aire y calefacción, menú a elección de carne, pollo o verdura  para su cena.

将触发此错误

我想您应该使用前面描述的换行格式。看起来您有两个选项，下面是一个使用“>”符号组合的快速示例

parse.rb文件位于此处：

require 'yaml'
foo = YAML.load_file('foo.yaml')
puts foo

以下是YAML文件的内容：

one_line: one line of text
two_lines:
>
this is a couple lines of text
here we go...
final_line: final line of content

当您使用

ruby parse.rb

通过命令行运行此命令时，您将获得以下输出：

{"one_line"=>"one line of text", "two_lines"=>"this is a couple lines of text here we go...\n", "final_line"=>"final line of content"}

希望这是有道理的。我认为您只需要添加“>”并将文本移动到下一行
