在我的Single Table Inheritance模型中,我重写了基本模型中的inherited
方法,以便所有后代模型都可以被基本模型的名称识别。以下代码用于为所有继承的类的model_name方法添加重写。STI model_name的弃用警告解决方法
def self.inherited(child)
child.instance_eval do
def model_name
BaesModelDefinition.model_name
end
end
end
我注意到,这是Rails的3.2.3生产废弃警告:
DEPRECATION WARNING: It looks like something (probably a gem/plugin) is overriding
the ActiveRecord::Base.inherited method. It is important that this hook executes so
that your models are set up correctly. A workaround has been added to stop this
causing an error in 3.2, but future versions will simply not work if the hook is
overridden.
有另一种方法,我可以用它来解决这个问题MODEL_NAME?
