RailsTutorial rspec test is failling - ruby-on-rails

Question

I'm ashamed to make this question but I can't find my error, I am once again doing the rails tutorial from Michael Hartl, since the first time I wasn't able to do the proper TDD, anyways I have managed to have working every single test but one! the thing is that I test it manually on rails' console and it worked, I tried to reset the db with rake db:reset and rake test:prepare and obviously re-populating the db rake db:populate ok, straight to the point... I have the following test
describe "status" do
let(:unfollowed_posts) do
FactoryGirl.create(:micropost, user: FactoryGirl.create(:user))
end
let(:followed_user) { FactoryGirl.create(:user) }
before do
#user.follow!(followed_user)
3.times { followed_user.microposts.create!(content: "Lorem Ipsum") }
end
its (:feed) { should include(newer_micropost) }
its (:feed) { should include(older_micropost) }
its (:feed) { should_not include(unfollowed_posts) }
its (:feed) do
followed_user.microposts.each do |micropost|
should include(micropost)
end
end
end
according to me, everything is ok, I test it manually on rails console, however when runing the spec with rpsec spec/models/user_spec.rb it comes up with the following error
Failures:

Failure/Error: should include(micropost)

I don't understand why the user_id is changed if the code 3.times { followed_user.microposts.create!(content: "Lorem Ipsum") } doesn't touch followed_user at all, so... that's my headache now, why is this happening? is it a bogus behavior on rspec, thanks in advance, and sry for this dull question.

Answer 1

you need to change you feed method in user.rb file
from
def feed
Micropost.where("user_id = ?", user)
end
to
def feed
Micropost.from_users_followed_by(self)
end
as well as add method self.from_users_followed_by to your micropost.rb file
def self.from_users_followed_by(user)
followed_user_ids = "SELECT followed_id FROM relationships WHERE follower_id = :user_id"
where("user_id IN (#{followed_user_ids}) or user_id = :user_id", user_id: user.id)
end
