In doubles stats we should be able to see what single player we've lost to the most or have the worst record against, regardless of partners.

I gave this a crack over the long weekend and it all looked like trash.

My cleanest approach so far was:

• Rename ApplicationController -> BaseController
• Make new controller ApplicationController << BaseController
• Route all traffic through ApplicationController, where the text is parsed, and then dispatch commands from there

However, something about having a "...Controller" with no actual impact on the data feels off.

Looking for some guidance.

Technical details:

• A user will be able to initiate challenges by using the command
  /elo challenge @recipient_username gametype
• ~> A message will be sent to the challenge recipient that they have been directly challenged by @sender_username, with perhaps a message saying what their Elo rating delta will be if they win/lose (@alexinman ?)
• ~> Recipient will be able to accept or deny the challenge by using the same command:
  /elo challenge @sender_username gametype
  which will alert the challenge sender and all relevant channels (#gametype)
• A user will be able to withdraw existing challenges by using the command
  /elo unchallenge @recipient_username gametype
• ~> A message will be sent to the challenge recipient that the challenge has been withdrawn

Definition of done:

• When someone uses the challenge command, we just look up existing challenges with the given details, if a challenge already exists and was initiated by a different party then accept the challenge and announce the acceptance.
• If there is an existing challenge and the sender types the challenge command, Elo will display a short message saying that the challenge has already been initiated, with instructions on how to cancel a challenge.
• If no such challenge exists, initiate a new challenge.

If a Player exists that hasn't participated in any games, the rake task to fix up the ratings will not reset that player's rating back to 1000.

My most recent additions that added the ViewModels for the Leaderboard and Statistics broke the footer icon image URLs.

Is there a way to use the current system to record high-scores in a single play game?
I'd like to do something like /elo @matt.cassidy scored 1054 at tetris then be able to see a high score leaderboard for the game

The API now expects a slack_team_id because of the renaming of the team_id columns.

• PlayerTest
• GameTest
• GameTypeTest
• GameTypeViewModelTest
• GameViewModelTest
• LeaderboardViewModelTest
• PlayerViewModelTest
• CommandParserTest
• EloControllerTest
• GameControllerTest
• PlayerControllerTest

The Rank that shows up when viewing an individuals stats is including doubles and singles games in the query and therefore is not properly rendering their rank and the surrounding players.

/elo who should @username challenge at <game> would produce a list of recommendations of people to play.

The algorithm could take into consideration people that the challenger seldom plays, greatest possible elo award, etc.

Bonus points if there are actionable slack buttons to click by each of the challenger names to invoke the challenge feature as per #1

if no game type is specified in the /elo [user] beat [user] command
then the system should append the string with " at channel_name" and proceed normally
where (
-> if the channel name matches a game type
-> then the command succeeds
-> else the command fails and asks the user to specify a gametype
)

Right now, if you look at the stats of a doubles team (/elo stats @Alex and @Josh) it will show the "average rating" instead of the team's rank and nearby ranks.

Add the following streaks to stats if they're greater than 0:

• Longest Winning Streak
• Current Winning Streak
• Longest Losing Streak
• Current Losing Streak

I would like to see this be able to work

/elo stats <optional game> @matthew.cassidy and @alex.inman

And the stats would be filtered down to just that team
