class BankAccountController 

  def admin_index
    @bbans = Bbans.all
  end
  
  def user_index
    @bbans_user = current_user.bbans.all
  end

end


# View user_index
@bbans.each{|b| puts b }

-> crash

-----------------

class BankAccountController 
  expose(:bbans){ Bbans.all }
  expose(:bbans_user){ Bbans.all }
  
  def admin_index
  end
  
  def user_index
  end
end

# View user_index
bbans.each{|b| puts b }

-> works
