============================
Django Cloud Tasks
============================
* Forked from https://github.com/GeorgeLubaretsi/django-cloud-tasks
Integrate `Google Cloud Tasks <https://goo.gl/Ya0AZd>`_ with Django.
Package provides easy to use decorator to create task handlers.
App looks for tasks in ``cloud_tasks.py`` files in your installed applications and auto-registers them.
Package is in early alpha and it does not have any real security at the moment. You need to authorize requests coming
to your instances yourself.
Prerequisites
=============
- Django 1.8+
- Python 3.4, 3.5, 3.6
Dependencies
============
- `google-api-python-client <https://pypi.python.org/pypi/google-api-python-client/>`_
Documentation
=============
TODO
Installation
============
(1) Install latest version from Github (PyPy package will be available as soon as stable version is released):
.. code-block:: sh
pip install -e git+git@github.com:rgutierrez-cotech/django-cloud-tasks.git#egg=django_cloud_tasks
(2) Add ``django_cloud_tasks`` to ``INSTALLED_APPS``:
.. code-block:: python
INSTALLED_APPS = (
# ...
'django_cloud_tasks',
# ...
)
(3) Optionally, set up Google Cloud credentials in your settings.py for use with Django Cloud Tasks. If you are using a service account, make sure the account has the "Cloud Tasks Admin" permission.
.. code-block:: python
# install these if they are not already installed
import google.auth
from google.oauth2 import service_account
# ...
# To use application default credentials:
google_cloud_credentials, project = google.auth.default()
# To use a service account JSON file:
google_cloud_credentials = service_account.Credentials.from_service_account_file(
'/path/to/key.json')
(4) Add configuration to your settings
.. code-block:: python
DJANGO_CLOUD_TASKS={
'project_location_name': 'projects/{project_name}/locations/us-central1',
'task_handler_root_url': '/_tasks/',
},
# This setting allows you to debug your cloud tasks by running actual task handler function locally
# instead of sending them to the task queue. Default: False
DJANGO_CLOUD_TASKS_EXECUTE_LOCALLY = False
# If False, running `.execute()` on remote task will simply log the task data instead of adding it to
# the queue. Useful for debugging. Default: True
DJANGO_CLOUD_TASKS_BLOCK_REMOTE_TASKS = False
# Optional argument. Specify a google.auth.credentials.Credentials object to use with the API
# Discovery service. Can be application default credentials or credentials generated from a
# service account JSON file. Default: None
DJANGO_CLOUD_TASKS_CREDENTIALS = None # or google_cloud_credentials if you defined this above
(5) Add cloud task views to your urls.py (must resolve to the same url as ``task_handler_root_url``)
.. code-block:: python
# urls.py
# ...
from django.urls import path, include
from django_cloud_tasks import urls as dct_urls
urlpatterns = [
# ...
path('_tasks/', include(dct_urls)),
]
Quick start
===========
Simply import the task decorator and define the task inside ``cloud_tasks.py`` in your app.
First parameter should always be ``request`` which is populated after task is executed by Cloud Task service.
You can get actual request coming from Cloud Task service by accessing ``request.request`` in your task body and
additional attributes such as: ``request.task_id```, ```request.request_headers```
.. code-block:: python
# cloud_tasks.py
# ...
from django_cloud_tasks.decorators import task
@task(queue='default')
def example_task(request, p1, p2):
print(p1, p2)
print(request.task_id)
Pushing the task to the queue:
.. code-block:: python
from my_app.cloud_tasks import example_task
example_task(p1='1', p2='2').execute()
Pushing remote task to the queue (when task handler is defined elsewhere):
.. code-block:: python
from django_cloud_tasks import remote_task
from django_cloud_tasks import batch_execute
example_task = remote_task(queue='my-queue', handler='remote_app.cloud_tasks.example_task'):
payload_1 = example_task(payload={'p1': 1, 'p2': '2'})
payload_2 = example_task(payload={'p1': 2, 'p2': '3'})
# Execute in batch:
batch_execute([payload_1, payload_2])
# Or one by one:
payload_1.execute()
payload_2.execute()
You can also send tasks in batch if latency is an issue and you have to send many small tasks to the queue
(limited to 1000 at a time):
.. code-block:: python
from my_app.cloud_tasks import example_task
from django_cloud_tasks import batch_execute
tasks = []
for i in range(0, 420):
task = example_task(p1=i, p2=i)
tasks.append(task)
batch_execute(tasks)
It is also possible to run an actual function using ``run`` method of ``CloudTaskWrapper`` object instance that is returned after task is called (this can be useful for debugging):
.. code-block:: python
task = example_task(p1=i, p2=i)
task.run()
