0:00 There's lots more to the ORM I've only begun to scratch the surface. You can modify your models to specify the default query order.
0:10 Cause validations at the field level, cause validations at the database level, and do even more funky things with your queries such
0:19 as grouping results aggregation, think summing up some values, and returning dictionaries or individual fields instead of models.
0:30 There is a complete obstruction of querying the database as well. You can build special queries by creating query objects or if you need to fine tune
0:39 things, you can specify the SQL directly although you really want to know what you're doing before you try that.
