保持控制器清洁
假设我有一些逻辑正在对传递到控制器操作的参数哈希执行。我想将逻辑封装在一些方法中，以保持代码易于理解并保持控制器干净。我可以将 Order 模型中的方法作为类级方法。然而，这些方法并不是 Order 模型域职责的真正核心。我的问题是 Rails 中存放这些类型方法的最佳位置在哪里？
OrdersController < ApplicationController
def update
# check some conditions here on the params hash...
# need some methods to do it...
# where's a good place for these methods other than model or controller?
end
end
Let's say I have some logic that's being performed on the params hash passed into a controller action. I'd like to encapsulate the logic in some methods to keep the code understandable and to keep the controller clean. I could put the methods in the Order model as class-level methods. However, these methods are not really core to the domain responsibility of the Order model. My question is where's the best place to house these type of methods in Rails?
OrdersController < ApplicationController
def update
# check some conditions here on the params hash...
# need some methods to do it...
# where's a good place for these methods other than model or controller?
end
end

使它们成为控制器的私有实例方法。
Make them private instance methods of the controller.
将这些放入 ApplicationHelper 中怎么样？
How about putting these in ApplicationHelper?
