Comparators¶
The syntax where={'id': 123} works well for = conditions but breaks down for other operators. For that purpose, jardin offers comparators.
For example
>>> from jardin.comparators import *
>>> User.count(where={'created_at': gt(datetime.utcnow() - timedelta(day=1))})
# SELECT COUNT(*) FROM users WHERE created_at > '2018-04-29 12:00:00';
