问题描述
我想的ActiveRecord使用回调自动设置一些数据库字段。
I would like ActiveRecord to set some DB field automatically using callbacks.
class Product < ActiveRecord::Base
after_create :set_locale
def set_locale
self.locale = I18n.locale
end
end
在./script/console我
In ./script/console I do
p = Product.create
p
现场p.locale未设置。我做了什么错?
Field p.locale is not set. What did I do wrong?
推荐答案
before_create 被称为之前 Base.save 的,因为你不保存它不获取调用。
before_create is called before Base.save, since your not saving its not getting called.
编辑:
class Product < ActiveRecord::Base
before_create :set_locale
def set_locale
self.locale = I18n.locale
end
end
通过这个在您的控制器将工作,你希望它。
With this in your controller will work how you want it to.
@product = Product.create # before_create will be called and locale will be set for the new product
