@MaysaMacedo Please add a screenshot in the first PR comment.
LGTM otherwise.

@dclarizio @martinpovolny Tested in UI and can be merged.
(spec failures seem unrelated)

@MaysaMacedo @AparnaKarve this travis failure DOES look related:

  2) PhysicalServerController#show should eq 200
     Failure/Error: it { expect(response.status).to eq(200) }
       expected: 200
            got: 500
       (compared using ==)

@dclarizio You are right. I just saw the first error which affected a lot of PRs yesterday.

@MaysaMacedo Let me know if you need help resolving the spec failure.

[AparnaKarve]

@MaysaMacedo To resolve the spec error, please add the following in the #show spec in physical_server_controller_spec --

computer_system = FactoryGirl.create(:computer_system, :hardware => FactoryGirl.create(:hardware))
physical_server = FactoryGirl.create(:physical_server, :computer_system => computer_system)

@MaysaMacedo While merging the 'master' commit sometimes addresses the merge conflict error (referring to f447558), the recommended approach to resolve the merge conflict would be to rebase your current branch with master.
It just keeps the commit history cleaner.
Could you please rebase and repush? Thanks.

[MaysaMacedo]

@AparnaKarve When rebasing with master 47 commits are created and bigger conflicts are generated

[AparnaKarve]

@MaysaMacedo Let's discuss how to rebase in gitter.
