好吧,基本上,这就是问题。令人困惑的是,诸如titleize之类的方法似乎可以正常工作,但是tableizepluralizesingularize却不行。

我忘了要求什么吗?

(另外,我注意到this page提供了类似"post".pluralize的示例,当我尝试时,产生了NoMethodError: undefined method 'pluralize' for "post":String。但是也许这可以保存另一个问题。)

最佳答案

无需添加新方法到#pluralize类即可访问String:

require 'active_support/inflector'
ActiveSupport::Inflector.pluralize('test')
#=> "tests"

对于String类:
require 'active_support/core_ext/string'
"test".pluralize
#=> "tests"

实际上在下面调用ActiveSupport::Inflector.pluralize:
def pluralize
  ActiveSupport::Inflector.pluralize(self)
end

关于ruby - 使用ActiveSupport::Inflector(在irb中)无法获得复数/单数,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/5140753/
