问题描述
我看到警告:
DEPRECATION WARNING: Base#after_update has been deprecated, please use Base.after_update :method instead. (called from <class:City> at /home/petrushka/webdev/my_app/app/models/city.rb:4)
我应该写些什么,而不是
What should I write instead of
def after_update
....
end
推荐答案
您应输入以下内容:
after_update :your_custom_method # macro-style
至少可以传递一个块而不是方法:
at least you can pass a block instead of a method:
after_update do |model|
model.name = model.name.capitalize unless model.name.blank?
end
