Rails验证full_name

Question

嘿......你如何验证一个full_name字段(名字姓氏).

Answer 1

考虑如下名称:

• Jan Levinson-Gould女士
• 小马丁·路德金博士
• Brett d'Arras-d'Haudracey
• 布鲁诺

您可能只想确保不存在某些字符集,而不是验证那里的字符.

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
