Creating Friendships - What is a Joint Table - undefined method 'gravatar_url' for nil:NilClass

I'm running

test "should create status for current user when logged in"

I can get the main test to fail and then add the code to make it pass, but I still get one more error which seems to have little to do with my test...not sure.

Here it is:

test_should_get_index(StatusesControllerTest): ActionView::Template::Error: undefined method `gravatar_url' for nil:NilClass

I have run various rake db commands after reading similar posts on the forum but none have worked.

Any ideas out there?

Thanks!

I figured out the answer from this thread: https://teamtreehouse.com/forum/getting-an-error-on-the-gravatarurl-method-when-testing-statuscontroller.

It had to do with statuses.yml and users.yml corresponding to eachother.

Hey Elaine Ryan that error means that the user whose gravatar_url you're trying to access is empty. In the statuses controller test you're working on, try making sure that each status has a user attached to it.

Thanks for replying Jason Seifer. I feel slightly embarrassed at this point on the track to say that I don't know what "making sure that each status has a user attached to it" looks like. I'm following along with the videos but having a hard time getting the fundamentals underlying each lesson. There are a bunch of tests and statuses are referred to as the symbol :status, the instance variable @status and status: followed by a hash.

Some, like this one,

test "should show status" do get :show, id: @status assert_response :success end

make no reference to a user.

In which cases do I need to make sure a user is attached and what would that look like?

Thanks!

Elaine Ryan check your test/fixtures/statuses.yml and look to see if it has a user key. The status fixture will look something like this:

one:
  content: test

Make sure there's a "user" key in there that corresponds to one of the names in test/fixtures/users.yml:

one:
  user: mike
  content: test

test/fixtures/users.yml

mike:
  first_name: Mike
  last_name: TheFrog
  ....
