How to access rails variable in assest pipelin

Hi,
I am using devise for my user management. I am using angular js for my
UI. I have folder structure like this for html: app/assets/partials/

I have added index.html.erb file over it. Now when I am going to
access
like this: <%= current_user %> I am getting error like: NameError
(undefined local variable or method `current_user’ for
#<#Class:0xa06acc0:0xc2db160>.
