save(:validate => false) 涵盖了什么? [英] What is covered by save(:validate => false)?

问题描述

我刚刚使用这样的代码实现了一些自定义的counter_cache:

I just implemented a number of custom counter_caches using code like this:

def after_save
    self.update_counter_cache
end
def after_destroy
    self.update_counter_cache
end
def update_counter_cache
    self.company.new_matchings_count = Matching.where(:read => false).count
    self.company.save
end

我的问题是 - 命令 Model.save(:validate => false) 实际上阻止了诸如 validates_with 或 before_validation?

My question is this - what does the command Model.save(:validate => false) actually prevent beyond things like validates_with or before_validation?

如果我保留现有保存而不进行验证，我的自定义 counter_caches 会受到影响吗?

Will my custom counter_caches be affected if I keep my existing saves without validation?

推荐答案

如果传入 :validate=>false，它会跳过有效的?命令.其他功能都一样.

If you pass in the :validate=>false, it skips the valid? command. Everything else functions the same.

您可以在此处查看代码:http://api.rubyonrails.org/类/ActiveRecord/Validations.html

You can check the code out here: http://api.rubyonrails.org/classes/ActiveRecord/Validations.html

def save(options={})
  perform_validations(options) ? super : false
end

...

if perform_validation
  valid?(options.is_a?(Hash) ? options[:context] : nil)
else
  true
end
