Layout

from twisted.internet.defer import inlineCallbacks, returnValue
import databases
from model import fields, Model, BaseModel
db_name = "ORMdatabase" # Database name
user = "user" # User name
password = "password" # Password
DATABASE = databases.PostgresqlDatabase(db_name, user=user, password=password)
__all__ = ["Test1"]
class Test1(Model):
    class Meta:
        database = DATABASE
    code = fields.CharField(max_length=50)
    user_id = fields.IntegerField()

Usage

test1s = yield (baseModels.Test1.all()
              .where((baseModels.Test1.code == "code1") | (baseModels.Test1.code == "code2"), baseModels.Test1.user_id == 1 ).execute())
if test1s[0]:
    for test in test1s:
        print(test.dictValues)
