I have a FastAPI app with an existing MySQL database, and I'm trying to use Tortoise ORM. The (simplified) main FastAPI file looks like this:
...ANSWER
Answered 2020-Nov-27 at 10:58The problem was coming from the async nature of FastAPI and Tortoise ORM. We have to wait for FastAPI to load and Tortoise to register the models.
So we can successfully do an async request that waits for FastAPI to load, and Tortoise ORM to request, like this:

ANSWER

does not automatically retrieve related data for the model object from the database, until one asks it to do that. It just generates QuerySet
object for related data without actually hitting the database.
To actually get data you need to use prefetch_related()
or fetch_related()
before printing of your objects. Doc says:
General rule about how
prefetch_related()
works is that each level of depth of related models produces 1 additional query, so.prefetch_related('events__participants')
will produce two additional queries to fetch your data.
Like so:

Is there a way to register databases in tortoise-orm from my Sanic app other than calling Tortoise.init
?
ANSWER
Answered 2020-May-13 at 21:37Yes, you can use register_tortoise
available from tortoise.contrib.sanic
It registers before_server_start
and after_server_stop
hooks to set-up and tear-down Tortoise-ORM inside a Sanic webserver. Check out this sanic integration example from tortoise orm.

Install tortoise-orm
You can use tortoise-orm like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
