Given a forked repo, how can I use github3.py to find the parent or upstream repo that it was forked from? This is fairly easy with requests but I can not figure out how to do it in github3.py.
With requests:
for repo in gh.repositories_by(username): # github3.py provides a user's repos
if repo.fork: # we only care about forked repos
assert 'parent' not in repo.as_dict() # can't find parent using github3.py
repo_info = requests.get(repo.url).json() # try with requests instead
assert 'parent' in repo_info, repo_info # can find parent using requests
print(f'{repo_info["url"]} was forked from {repo_info["parent"]["url"]}')
# https://github.com/username/repo was forked from
# https://github.com/parent/repo
This use case is similar to How can I find all public repos in github that a user contributes to? but we also need to check the parent/upstream repo that the user's repo was forked from.
The documentation shows that this is stored as repo.parent, that however, is only available on Repository objects. repositories_by returns ShortRepository objects.
This would look like:
for short_repo in gh.repositories_by(username):
repo = short_repo.refresh()
if repo.fork:
parent = repo.parent
