[Phase 4] SwapRequest Cancel Status

[michac789]

Consider having 'Revoked' (R) status instead of just Searching, Waiting, Completed... So we have it documented (still in database) rather than deleting it, we can use this for this scenario:

• User decided to cancel swap request while still searching or while waiting, instead of deleting the instance, make the status as 'Revoked' so it can be tracked
• When a pair is matched, but one side can't be contacted... If the other side decided to search again, then by default the other pair will have the status of 'Revoked'

changed to mid priority... this one would be open for discussion first and confirmation with FE team

Plan:

Now, there are 4 status for swap requests: searching (S), waiting (W), completed (C), revoked (R) When you first create SwapRequest, it will have a status of S. When status is S, you can:

• Edit your contact information and contact type
• Cancel searching, no penalty is given directly but it'll add up the number of SwapRequest (if you have >10, you get banned), make status to R If a pair is found, it will have a status of W. When status is W, you have these 3 options:
• You can 'Search Another Pair': can only be done after 24 hrs cooldown (to prevent abuse), change status to S and perform pairing algorithm again for the same course indexes, create Violation model for the user's pair and change status to R
• You can 'Cancel Swap': create Violation model, move status to R, rerun search algorithm for pair (make it to S again if not found)
• You can 'Mark Completed': move status to C for both you and your pair When status is C, you can only:
• Report Pair: you can do this if your pair mark this swap request as completed, but haven't make the swap; a Violation model is created for the user's pair

############################################## Future hypothetical plan: Sorry, you have been banned to index swapper. If you think this is a mistake, please contact su-itc@e.ntu.edu.sg. Users will be banned to index swapper if they make 3 or more violations as the following:

• Cancel swap when a pair is already found
• Your pair click 'Search Another Pair' (after 24 hrs cooldown, meaning that you can't be contacted or does not fulfill your obligation to swap index with your pair)
• You mark SwapRequest as completed, but your pair reported you of not completing the SwapRequest Or, if they have more than 10 SwapRequest in a season.
