    id = models.Uuid4Field(uuid_type='v1', db_column='id')

with this query

    user_query = Users.objects.filter(
        id=uuid.UUID(user_id, version=1))

    print(user_query.query)
    users = []
    async for user in user_query:
        users.append(user)
    print(f"results:{users}")

case 2:
I find some check related the Pkfield so I change the model

class Users(models.Model):
    table_name = "users"
    uid = models.Uuid4Field(uuid_type='v1')

with this quey

async def user_orm_info(request, user_id):
    # This too ugly why not sql session
    user_query = Users.objects.filter(
        uid=uuid.UUID(user_id, version=1))

    print(user_query.query)
    users = []
    async for user in user_query:
        users.append(user)
    print(f"results:{users}")

This time error :

So I print the print(user_query.query)

Got some thing like:

[{'action': 'db__select_all', 'select': '*', 'table_name': 'Users', 'ordering': None, 'join': ''}, {'action': 'db__where', 'condition': 'users.id = 7a8ef3bc-b4da-11e7-8e7a-f0def1b6e8a0'}]

It seem like 'users.id = 7a8ef3bc-b4da-11e7-8e7a-f0def1b6e8a0' the uuid need be round by ''.

Right now asyncorm only accepts serial primary keys, I will add other primary keys and index fields as soon as possible.
Sorry for the inconvenience and late response.

[Héctor Alvarez]

Just did some changes so any field can be indexed, will allow other primary keys soonish.

Push pending because I have intermittent internet access
