It looks like this is not possible. :-( The GH doc for updating a PR says "State of this Pull Request. Either open or closed"

gh api is available to make draft to ready but there are other challenges of assigning reviewers/team reviewers

challenge to remove as team reviewers

• draft mode to ready mode
• gh api subprocess call for calling to draft mode to ready mode
• gh api subprocess call to add team-reviewers
• remove team reviewers (attached the challenge, gh api is not capable of doing this, we have to look at other libraries like ocktokit etc

• draft mode to ready mode

HOW? What about Ready -> Draft? Thanks!

HOW? What about Ready -> Draft? Thanks!

use the api call to convert to draft -> true

This doesn't work: pr.update({'draft':'true'}), nor does pr.edit(state="draft")
Can you please give an example? Thanks!!

you have to use pygit subprocess ` result = subprocess.run(
[path_to_gh, "pr", "view", str(pr_number), "--repo", f"{owner}/{repo_name}"],
capture_output=True, text=True,
env={"GH_TOKEN": token}
)

    if "Draft: false" in result.stdout:
        logger.info("PR #%s is already ready for review", pr_number)
        return

    subprocess.run(
        [path_to_gh, "pr", "ready", str(pr_number), "--repo", f"{owner}/{repo_name}"],
        env={"GH_TOKEN": token},
        check=True
    )`

Thanks, but that's not using PyGithub . . .

yes, that is the limitation, you will have to go to Octokit lib

On this GitHub doc page, they mention that the GitHub CLI has a gh pr ready. Looking at the function source it appears they are using the newer GraphQL API to mark a PR as ready for review

This SO answer comes to a similar conclusion and references issue ( google/go-github#1120 ) with more details

Looking at the REST API, it does not look like you can modify the draft attribute there: https://docs.github.com/en/rest/pulls/pulls?apiVersion=2022-11-28#update-a-pull-request

Looking at the GraphQL API, marking a pull request as "ready for review" seems to be the desired action: https://docs.github.com/en/graphql/reference/input-objects#markpullrequestreadyforreviewinput

There is prior art of calling out to the GraphQL API in PyGithub:
https://github.com/PyGithub/PyGithub/blob/85087354078e426125dbbf88041bbaa6f35d8199/github/PullRequest.py#L787.L824

So this feature should be easy to add. Contribution welcome!

Indeed one of my collaborators pointed out this discussion thread, which had a workable approach: https://github.com/orgs/community/discussions/70061
