在文件.yml中將字符串拆分爲兩行

Question

我需要在文件.yml中將字符串拆分爲兩行或三行。問題是，如果我試圖分裂成兩行觸發一個錯誤的最後一個字段描述， 所以我把它一個行

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. 

這個錯誤被觸發。

Answer 1

我想你想使用here描述的換行符格式。看起來你有兩種選擇，下面是一個使用「>」符號放在一起的簡單例子。

parse.rb文件位置：

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

這裏是YAML文件的內容：

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

當你通過命令行與ruby parse.rb運行它，你會得到下面的輸出：

{"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"} 

希望這是有道理的。我想你只需要添加「>」並將文本移動到下一行。
