If we believe chatGPT:
The Session() call creates a new SQLAlchemy Session, which opens a new transaction. It's not recommended to start a transaction in the init method.
The reason is that the init method is called when an instance of the class is created. If you start a transaction in the init method, the transaction will be open for the entire lifetime of the object, which is not what you typically want. Transactions should be short-lived and should be started just before performing database operations, and ended (committed or rolled back) as soon as possible.
Instead, you should create the sessionmaker in the init method and then start a new session in each method that performs database operations, using a context manager (with statement). This ensures that each session is properly closed, even if an error occurs during the database operations.
