python - SQL Alchemy: Select entire row by distinct column_a and max column_b -


consider model:

class pet(db.model):     id = primary_key     type_of_pet = string_column     name = string_column     foo_relation = int_column     added_time = int_column

say there 100 entries in table , 20 different pet types (cats, dogs, turtles, rabbits, etc).

is possible recent additions each pet type in single query?

i thought like:

unique_pets = pet.query.distinct(pet.type_of_pet).limit(5)

would work distinct more returning list of unique column names , not full row results.

any insight appreciated. note aws aurora (mysql) server
