ruby-on-rails - 标题化连字符的名称

Question

Rails' titleize方法删除连字符，Ruby 的 capitalize方法不会将连字符后面的单词大写。我想要如下内容:

"mary-joe spencer-moore" => "Mary-Joe Spencer-Moore"

"mary-louise o'donnell" => "Mary-Louise O'Donnell"

Answer 1

Check Titelize implementation从中你可以得到:

"mary-joe spencer-moore".humanize.gsub(/\b('?[a-z])/) { $1.capitalize }

会给你 => "Mary-Joe Spencer-Moore"

你可以在字符串类中为它写一个函数，添加到 intalizers:

class String
  def my_titleize
    humanize.gsub(/\b('?[a-z])/) { $1.capitalize }
  end
end

然后从您的代码中:

"mary-joe spencer-moore".my_titleize
