嘿,你如何验证一个full_name字段(姓氏).

解决方法

考虑像：

> Jan Levinson-Gould女士
>马丁·路德·金博士
> Brett d’Arras-d’Haudracey
>布鲁诺

而不是验证那里的字符,您可能只想确保一些字符集不存在.

例如：

class User < ActiveRecord::Base

  validates_format_of :full_name,:with => /A[^0-9`!@#$%^&*+_=]+z/
  # add any other characters you'd like to disallow inside the [ brackets ]
  # metacharacters [,,^,$,.,|,?,*,+,(,and ) need to be escaped with a 

end

测试

Ms. Jan Levinson-Gould         # pass
Dr. Martin Luther King,Jr.    # pass
Brett d'Arras-d'Haudracey      # pass
Brüno                          # pass
John Doe                       # pass
Mary-Jo Jane Sally Smith       # pass
Fatty Mc.Error$               # fail
FA!L                           # fail
#arold Newm@n                  # fail
N4m3 w1th Numb3r5              # fail
