CanCan - "user" parameter is nil - Rails 4
cancan, rails-admin, ruby, ruby-on-rails, ruby-on-rails-4
Solution
Solved. In `config/initializers/rails_admin.rb` we have to specify the `current_user_method` as
config.current_user_method { current_user } # refers to the current_user helper method in my case
Now everything is working perfectly. I am surprised why this isn't specified anywhere in the documentation.
Problem
I am using Rails 4.0.1 and ruby 2.1.1. I am trying to integrate cancan with rails_admin. My `application_controller.rb` looks like this ``` helper_method :current_user private def current_user @current_user ||= User.find_by(email: session[:user_id]) if session[:user_id] end ``` My `current_user` helper method is working fine from rest of the application. My `ability.rb` looks like this ``` class Ablity include CanCan::Ability def initialize(user) if user can :access, :rails_admin end end end ``` Control is not going inside the if condition at all, which means the "user" parameter is "nil". When I try to access rails_admin I get a `CanCan::AccessDenied` exception. Where am I going wrong? Edit : I am not using devise for authentication Update : I've replaced `cancan` with `cancancan` version 1.8. Still not working
