Init events on Aggregate in-memory

[filipelobo]

Use the orm.reconstructor decorator on the events attribute for the Aggregate model to init and load it only on memory, according to the example on the Constructors and Object Initialization section of SQLAlchemy docs:

from sqlalchemy import orm


class MyMappedClass:
    def __init__(self, data):
        self.data = data
        # we need stuff on all instances, but not in the database.
        self.stuff = []

    @orm.reconstructor
    def init_on_load(self):
        self.stuff = []
