flask sqlachemy filter by date code example

Example 1: sqlalchemy filter date today

from sqlalchemy import func
from datetime import date

my_data = session.query(MyObject).filter(
    func.date(MyObject.date_time) == date.today()
).all()

Example 2: less than date query sqlachemy

current_time = datetime.datetime.utcnow()

ten_weeks_ago = current_time - datetime.timedelta(weeks=10)

subjects_within_the_last_ten_weeks = session.query(Subject).filter(
    Subject.time > ten_weeks_ago).all()
