Rails 3-如何跳过验证规则? [英] Rails 3 - how to skip validation rule?

问题描述

我有用于此验证规则的注册表格:

I have for the registration form this validation rule:

  validates :email, 
    :presence => {:message => 'cannot be blank.'}, 
    :allow_blank => true, 
    :format => {
      :with => /\A[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]+\z/, 
      :message => 'address is not valid. Please, fix it.'
    }, 
    :uniqueness => true

此规则检查用户是否填写了注册表格的电子邮件地址(及其正确格式).

This rule check, if a user fill into the registration form email address (+ its correct format).

现在，我正在尝试增加使用Twitter登录的机会. Twitter不提供用户的电子邮件地址.

Now I am trying to add the opportunity to log in with using Twitter. Twitter doesn't provide user's email address.

在这种情况下，如何跳过上面的验证规则?

How to skip in this case the validation rule above?

推荐答案

您可以在将用户保存到代码中时跳过验证.代替使用user.save!，而使用user.save(:validate => false).从 Omniauth上的轨道广播情节

You can skip validation while saving the user in your code. Instead of using user.save!, use user.save(:validate => false). Learnt this trick from Railscasts episode on Omniauth
