Still having issues with undefined method

Hey guys, I posted on here yesterday and still haven't been able to figure out the problem..

Here is the error I'm getting while running the test for ActivitiesControllerTest

1) Error:
test_should_get_index(ActivitiesControllerTest):
NoMethodError: undefined method `friends' for nil:NilClass
/Users/justinlicata/Documents/ruby/treebook/app/controllers/activities_controller.rb:3:in `index'

Here is the the Activities Controller

class ActivitiesController < ApplicationController
  def index
    friend_ids = current_user.friends.map(&:id)
    @activities = Activity.where("user_id in (?)", friend_ids.push(current_user.id)).order("created_at desc").all
  end
end

and Here is the Activities Controller Test

require 'test_helper'
class ActivitiesControllerTest < ActionController::TestCase
  test "should get index" do
    get :index
    assert_response :success
  end
end

Lastly, while trying to access the Activity Feed Page, I get this errror

undefined method `friends' for nil:NilClass

and

undefined method `underscore' for nil:NilClass

Here are my files on Github https://github.com/licatajustin/treebook

Anyone know what I've missed? Thank you in advance for the help

Hi Justin,

Jason Seifer is on holiday right now. I'll see if I can help you.

It looks like, current_user, is not being set in the test. You need to make sure you have a user that's logged in to make sure your test passes.

Because current_user is nil, or undefined, the friends method that's being called will through the "undefined method friends' for nil:NilClass" error. So theassert_response :success` will fail because testing that route will actually throw an error or status code 500.

I believe this video will tell you how to use devise to log in during your test. Regards
Andrew

What was weird Andrew is that all my code was correct. I cloned it all into another directory and it worked fine!

Thank you for your help though

Very. have a good one

I have the same issue. Though, when someone I'm following creates a post, it shows up in the activity index page. Yet, when someone I'm following follows another person, I get the "undefined method `underscore' for nil:NilClass".
