I am using the latest ponyorm on Python 3.6.
I want to do some monkey patching on entity classes created at another stage (to add computed fields).
Any chance I can get the list of entities types available from the db object ?
In my models.py file:
from pony.orm import *
db = Database()
class OneEntity(db.Entity):
id = PrimaryKey(int, auto=True)
nom = Required(str)
class AnotherEntity(db.Entity):
id = PrimaryKey(int, auto=True)
someprop = Required(str)
In another file:
from models import *
db.bind(provider='sqlite', filename = 'test.db', create_db = True)
db.generate_mapping(create_tables = True)
def say_hello():
""" some dummy proc to monkey patch onto entity classes"""
print("hello")
#This works, but isn't workable for my use case (too many entity classes)
OneEntity.monkey_patched_method = say_hello
#And here I'd like to have the ability to list entity classes programmatically
for Entity in some_code_that_i_dont_know :
Entity.new_method = say_hello
In PonyORM Database
object has entities
property which is a dict of all associated entities:
for entity_name, entity_cls in db.entities.items():
print(entity_name)
