The if statement to reissue the access_token was wrong.

sqlalchemy.exc.OperationalError: (MySQLdb._exceptions.OperationalError) (2013, 'Lost connection to MySQL server during query')

Fix

CleadDB close connection up to 1min

attribute "key" from spotify api only shows root note and not shows the mode of it.

whene deleting a playlist, all tracks in the playlist will be removed.
ooyamatakehisa/bpm-searcher-frontend#18

For users who play DJ, create the feature to save bpm lists.
To this end, I need to make a login function firstly.

• remove this line(https://github.com/ooyamatakehisa/bpm-searcher/blob/feature/test/interactor/playlist_interactor.py#L63)
• remove track usecase from playlist interactor because it is not used

• handle the case where no query is specified
• delete runtime error
• return flask.Response object in controller
• fix typo

Must check if the specified playlist is created by the user.

spotify api returns 400 when id is invalid

  if response.status_code != requests.codes.ok:
      self.logger.error(
          f"cannot fetch tracks by ids correctly: {response.json()}"
      )

Also add error handling to ranking interactor

SSIA

今のところDBもないのでメモリに入れる

• add singleton decorator (injector)
• new access_token service
• add logger.info() message
• raise error when environmental variables are empty

no need to request spotify api to fetch chart information every time.
update per day?

• add testcase for playlist interactor, repository, and controller

  • interactor
  • repository
  • controller
  • model(patch_track_order)

• modify testcases for track interactor and track repository

  • interactor
  • repository

Through github workflow, automatically build frontend src.

ttl属性を設けてそこにexpireする時間を保存時に設定
取得時にその時間を過ぎていたら新しくaccess_tokenを取得して新たに上書きする

spotifyのaccess_tokenは1時間で期限が切れるためttlは50分に設定

Before

app.config["SQLALCHEMY_DATABASE_URI"] = (
    f"mysql://{envs.MYSQL_USER}:{envs.MYSQL_PASSWORD}@mysql/{envs.MYSQL_DATABASE}"
)

After

app.config["SQLALCHEMY_DATABASE_URI"] = (
    f"mysql://{envs.MYSQL_USER}:{envs.MYSQL_PASSWORD}@{envs.MYSQL_ADDR}/{envs.MYSQL_DATABASE}"

• "create" -> "save" in repository
• error handling in redis repository
• add logger to controller
• move get track function from spotify to repository
• use DTO

• send track data from front end(https://github.com/ooyamatakehisa/bpm-searcher/blob/feature/test/interactor/playlist_interactor.py#L103)
• #50
• no logger is given in init of playlist_interactor
• add docstring to methods in the playlist model
• in the add method in the playlist method, not to add a PlaylistTrack but a Track
• move process to get track information to inside if statement in /persistence/playlist.py
• add Optional typing to return value of the following function and add docstring

  class AuthUsecase(metaclass=ABCMeta):
      @abstractmethod
      def verify_user(self, id_token: str) -> dict:
          pass

• return playlist and playlist track object when delete_track function is called in playlist_interactor
