If I comment both config.cache_classes = true and config.eager_load = true then the server able to run without errors , I am not sure why this is , I know I should comment eager_load on production but if dont do that then getting the above issues. – Preshrunk

Answer 1

The error has been rised from mailers where I used "include ActionView::Helpers" out side the email class.

I got it fixed by keeping include ActionView::Helpers inside the class, I am not sure about this order of inclusion. I changed like the following

include ActionView::Helpers    
class EmailMailer < ActionMailer::Base

to

class EmailMailer < ActionMailer::Base
  include ActionView::Helpers

Hope it helps for someone , I am still searching about the order of including modules in classes , once I found required information I will post here .
