Bringing async capabilities to django ORM

Disclaimer: Don't use this module in production it's still in active development.

Django Async Orm

Django module that brings async to django ORM.

Installing

python -m pip install django-async-orm

then add django_async_orm to your INSTALLED_APPS list:

INSTALLED_APPS = [
    ...,
    'django_async_orm'
]

Usage

Django Async Orm will patch all your existing models to add async_* prefixed methods. To be

example:

class MyModel(models.Model):
    name = models.CharField(max_length=250)

you can use it as follow:

async def get_model():
    return await  MyModel.objects.async_get(name="something")

you can also iterate over a query set with async for:

async def all_models():
    all_result_set = await MyModel.objects.async_all()
    async for obj in all_result_set:
        print(obj)

Some wrappers are also available for template rendering, form validation and login/logout

Async login

from django_async_orm.wrappers import async_login

async def my_async_view(request):
    await async_login(request)
    ...

Form validation

from django_async_orm.wrappers import async_form_is_valid
async def a_view(request):
    form = MyForm(request.POST)
    is_valid_form = await async_form_is_valid(form)
    if is_valid_form:
        ...
    

Django ORM support:

This is an on going projects, not all model methods are ported.
