save（false）和save之间的区别（：validate => false） [英] Difference between save(false) and save(:validate => false)

问题描述

save（false）和 save（：validate => false）之间有什么区别？从我可以看出，功能是一样的。使用：validate 的版本在api中，导致我相信 save（false）是不推荐使用的版本？以下是对我的回应： https：/ /github.com/plataformatec/devise/wiki/How-To:-Create-a-guest-user 。该指南中有 save（false），但在使用时出现错误。我将其切换到：验证版本，并且工作正常。

What's the difference between save(false) and save(:validate => false)? From what I can tell, the functionality is the same. The version that uses :validate is in the api which leads me to believe save(false) is a deprecated version? This came up for me when following this: https://github.com/plataformatec/devise/wiki/How-To:-Create-a-guest-user. The guide has save(false) in there but I was getting errors when using it. I switched it to the :validate version and that worked fine.

推荐答案

在Rails之前的版本3之前，保存 被 ActiveRecord :: Base 中的方法，您可以通过 false 来绕过验证。

In Rails versions before than 3, save was a method in ActiveRecord::Base and you could pass false to it in order to bypass validations.

在Rails 3中，保存 被移动到 ActiveRecord :: Persistance ，然后您应该通过：validate => ;为了绕过验证，假到保存。

In Rails 3, save was moved to ActiveRecord::Persistance and since then you should pass :validate => false to save in order to bypass validations.
