Rails 验证 full_name [英] Rails validating full_name

问题描述

嘿...您将如何验证 full_name 字段(姓名姓氏).

Hey... how would you validate a full_name field (name surname).

推荐答案

考虑以下名称:

• 小姐扬·莱文森-古尔德
• 博士小马丁路德金
• Brett d'Arras-d'Haudracey
• 布鲁诺

您可能只想确保某些字符集不存在，而不是验证存在的字符.

Instead of validating the characters that are there, you might just want to ensure some set of characters is not present.

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
