问题描述
假设我有这个示例:
Example:
number:
cuarenta
cuarenta y uno
cuarenta y dos
cuarenta y tres
cuarenta y cuatro
cuarenta y cinco
cuarenta y seis
cuarenta y siete
cuarenta y ocho
cuarenta y nueve
我想对此进行解析,以使每个数字都像"cuaranta y nueve"一样.我很难想象如何做到这一点,因为在YAML中,您变成了与名词"相关的字符串.
And I'd like to parse this so that I have each of those numbers together like "cuaranta y nueve". I'm having trouble visualizing how to do that since in YAML, you're turned a string associated with "noun".
我的Yaml解析器看起来像这样:
My yaml parser looks like this :
File.open(Rails.root + 'lib/words/yamlicious.yml', 'r') do |file|
YAML::load(file).each do |topic, word_types|
temp_topic = Topic.create! name: topic
temp_words = word_types.map{|type, words| words.split(' ').map {|word| Word.create type: type, word: word, topics: [temp_topic] } }
temp_topic.words << temp_words
end
end
请注意,split
部分会破坏这一点,因为那样的话,根据我的示例,我将得到一个单词,即三个单词"cuarenta","y"和"uno".
Notice the split
part would ruin that because then I would get a word created per my example as three words "cuarenta", "y", and "uno".
推荐答案
To preserve newlines, you have to use the pipe character:
Example:
number: |
cuarenta
cuarenta y uno
cuarenta y dos
…
现在您可以split("\n")
