清理控制器，今天可以使用Merb风格的动作吗？

Question

In Rail 2.3.2 can I have merb style action definitions:

Eg: instead of

def show
  @user = User.find(params[:id])
end

Can I have:

def show(id)
  @user = User.find(id) 
end

What kind of crazy monkey patching do I need to do to get this working, note I only need this working for MRI so ParseTree is an option.

Note: there is a Rails 3 port of this functionality now.

Answer 1

EDIT: I was wrong: Method#parameters has been added to Ruby 1.9.2.

Original:

No, this is not possible in Rails.

There is almost zero chance of this making it into Rails 3.0. merb-action-args used ParseTree which doesn't and will not work on Ruby 1.9 , therefore making it unlikely that it will be included in Rails.

Answer 2

您可以在before_filter中将所有参数更改为实例var（例如@id）...

Answer 3

我正在运行Rails 2.3.3，而User.find（id）可以正常工作。
