Deleting a Family and Tracking Returns Old Location #198

Open cpressman opened 4 years ago

cpressman commented 4 years ago

This may all be connected with #156 but here are some more details:

I did all of this inside the latest docker container Steps to reproduce:

  1. Use POST data for a device until you have enough data to make a guess (with the same location)
  2. Use GET location_basic to confirm the guess. Since I only trained 1 position the probability should be 1
  3. Use DELETE database
  4. Confirm using GET location that the family no longer exists
  5. Use POST data like in #1 but with an empty location. This should mean there is still no training data but the database file should get recreated
  6. Use GET location_basic like in step 2

Expected results: No guesses found

Actual results The location trained in step 1 is still guessed.

Possible solution: When deleting the database the ai file should possibly get deleted as well.
