GradyMoran/pychal

Pychal is a drop-in replacement of pychallonge with some extra features and support for new Python versions. Pychal provides python bindings for the CHALLONGE! API.

The only diffence with the pychallonge is the dictionary keys with dashes are now with undescores for example the key 'created-at' is now 'created_at'.

• iso8601
• tzlocal
• pytz
• requests

• 3.4+

For the stable version

pip install pychal

For latest development

pip install -e git+http://github.com/ZEDGR/pychal#egg=pychal

import challonge

# Tell pychal about your [CHALLONGE! API credentials](http://api.challonge.com/v1).
challonge.set_credentials("your_challonge_username", "your_api_key")

# Retrieve a tournament by its id (or its url).
tournament = challonge.tournaments.show(3272)

# Tournaments, matches, and participants are all represented as normal Python dicts.
print(tournament["id"]) # 3272
print(tournament["name"]) # My Awesome Tournament
print(tournament["started_at"]) # None

# Retrieve the participants for a given tournament.
participants = challonge.participants.index(tournament["id"])
print(len(participants)) # 13

# Start the tournament and retrieve the updated information to see the effects
# of the change.
challonge.tournaments.start(tournament["id"])
tournament = challonge.tournaments.show(tournament["id"])
print(tournament["started_at"]) # 2011-07-31 16:16:02-04:00

See challonge.com for full API documentation.

The Challonge API has some issues with the attachments endpoints. The create and update endpoints are not working correctly. When you try to upload an attachment with asset(file) the API returns 500 internal server error. The same happens with asset + description. This problem has been reported to Challonge.

Other problems that I have noticed is that the check in process through the API seems weird. When you undo check in a participant the field 'checked_in' remains True but in the website the participant is correctly not checked in. That's why I haven't write any tests on this.

Fixed by pychal: In the datetime fields the api returns random timezone offsets, pychal convert those to your machine's local time. Also you can set any timezone you want with set_timezone function.

Pychal comes with a set of unit tests. The tests are not comprehensive, but do utilize each method and verify basic functionality.

In order to test behavior of the python bindings, API calls must be made to CHALLONGE!, which requires a username and api key. To run the tests with your credentials, set CHALLONGE_USER and CHALLONGE_KEY appropriately in your environment.

$ git clone http://github.com/ZEDGR/pychal pychal
$ CHALLONGE_USER=my_user CHALLONGE_KEY=my_api_key python pychal/tests.py

OK

Note that several tournaments are created, published, started, and completed over the course of the unit tests. These should be cleaned up by the end, but if any of the tests fail they may not be cleaned up. As long as the basic functions work, you can clean up errant tournaments as follows.

import challonge
challonge.set_credentials("my_user", "my_api_key")
for t in challonge.tournaments.index():
    if t["name"].startswith("pychal"):
        challonge.tournaments.destroy(t["id"])
