Celery wrapper that delays tasks until the django transaction has committed

Project description

# django-celery-oncommit

Delay all celery tasks until after the current django transaction has committed to prevent race conditions.

See the [django docs](https://docs.djangoproject.com/en/2.1/topics/db/transactions/#performing-actions-after-commit) for more details.

## Usage

`pip install django-celery-oncommit`

In your task file:

```python
from django_celery_oncommit import task

@task
def some_task(with_args):
"""Task that does stuff with objects"""
pass
```

Elsewhere:

```python
from mytasks import some_task

def function_used_in_django_code():
create_some_objects()
some_task.delay(args_referring_to_new_objects)
slow_operation_that_allows_the_race_condition()
```

Ta da!

## TODO

* provide a non-transaction-based option `apply_async` for when the user explicity knows how they want to interact with transactions
