How to pull changes from a pull request thats already checkout?

Question

I have checked out a PR using:

git fetch origin pull/pull_req_ID/head:NEWBRANCHNAME

However, I can't pull changes to my local branch from that PR.

Answer 1

If I understand the question correctly, another developer has pushed changes to a PR after you initially fetched it, and you want to get the latest updates. This should work:

git checkout NEWBRANCHNAME
git fetch origin pull/pull_req_ID/head
git rebase FETCH_HEAD  # Or git merge FETCH_HEAD

Bitbucket example:

git fetch origin pull-requests/101/from:pr/101
git checkout pr/101

# ...New changes pushed to PR #101 by another developer

git fetch origin pull-requests/101/from
git rebase FETCH_HEAD

Gitlab example:

git fetch origin merge-requests/101/head:mr/101
git checkout mr/101

# ...New changes pushed to MR #101 by another developer

git fetch origin merge-requests/101/head
git rebase FETCH_HEAD
