Hey Michelle,

Great work here. There might be some more efficient ways of doing what you're doing, but if there are, I don't know them.

I'm just harping on some style stuff, but nothing major.

Thanks,

Tests pass, and local testing verifies that this patch indeed fixes the problem.

I went digging through resources.py to see what kind of patterns we use, and I've got a few recommendations. See below.

Once those are fixed, I'll give my ship-it.

So, looking through the rest of resources.py, I think this pattern is more common:

diff_revision = kwargs.get('diff_revision', None)
review_id = kwargs.get('review_id', None)

if diff_revision:
  # Do stuff
elif review_id
  # Do other stuff

Fix it!

So, I made some comments on style, since I think that'll be helpful, but I have a couple questions/comments about the change.

1) Does this do anything for accessing actual individual comments with fake diff revisions or review IDs? (Is that broken too?)

2) Can you go into more detail on the second part of the change involving the local IDs? This doesn't seem completely right to me...

3) There should be unit tests covering each failure case, and making sure the results are expected. These should fail before this change, and pass after.

1) Accessing individual diff comments with fake diff revisions or review IDs isn't broken.

2) Previously, we would pass in the local ID to FileDiffResource.get_queryset but the function would assume that review_request_id was always primary key instead of the local ID.  I added in a check to convert the local ID to the PK if we were using a local site.

3) The reason why unit tests weren't failing before was because the bugs were hiding each other.  Our unit tests would pass in local IDs for the review request ID, which would be handled like a PK instead and thus wouldn't grab an actual FileDiffResource. However, accessing diff comments also had a bug that would return an empty list of diff comments if the FileDiffResource didn't exist instead of a DOES_NOT_EXIST. Since the unit test only checked to make sure that we weren't returning a DOES_NOT_EXIST, it would always pass. (Sorry if that's a bit rambly.)

Is there a time when we would not have a review ID?

I think we only have the review ID when we try to get the diff comments using review-requests/<review-request>/reviews/<review-id>/diff-comments, and not when we use review-request/<review-request>/files/<file-id>/diffs/<diff-revision>/diff-comments.

Given the length of arguments and the wrapping, do one parameter per line, all aligned. That includes 'request' (on the next line).
