Issue with railscast# 238 , date_select not working with rails 4.

I am trying railscast#238. I am using rails 4 and mongoid(4.0.0).When trying to add published_on field with date_select helper. It is not able to save into collection. Then, I added :published_on in the permit function. But then also I am getting error. I also tried including Mongoid::MultiParameterAttributes but it is not found. I think its been removed from mongoid. Below is the error in the log file:

Summary: Without including Mongoid::Attributes::Dynamic in your model and the attribute does not already exist in the attributes hash, attempting to call Article#published_on(1i)= for it is not allowed. This is also triggered by passing the attribute to any method that accepts an attributes hash, and is raised instead of getting a NoMethodError. Resolution: You can include Mongoid::Attributes::Dynamic if you expect to be writing values for undefined fields often.): app/controllers/articles_controller.rb:44:in block in update' app/controllers/articles_controller.rb:43:inupdate'

If i remove published_on from permit:

You need to include Mongoid::MultiParameterAttributes in your document class.

In Mongoid 4.0 you also need to define that module in yor lib/ folder. See detailed explanation in this blog
