Create simple 'if this then that' style rules in your Django
application. Comes with a bunch of ready-to-use actions and conditions,
but is also easily extensible and allows model specific
actions/conditions.
Conditioner helps you create simple rules that consist of a condition
(if this), and an action (then that). It's currently a work in progress,
but we successfully use it in production with custom conditions and
actions that allow us to send 'reminder' emails to users before their
license expires.
It was created to 'scratch an itch', and for the foreseeable future we
will prioritise implementing use-cases needed by us as. The overall
goal, however, is to create a set of useful actions and conditions that
could be applied to a number of different scenarios.
Oh, and shout-out to
`django-polymorphic <https://github.com/django-polymorphic/django-polymorphic/>`__
without which this whole thing would be much harder to do.
Installation
------------
>From PyPI:
.. code:: shell
$ pip install django-conditioner
Usage
-----
If you want to use the already implemented actions and conditions then
all you need to do is install the package, add ``conditioner`` to your
list of ``INSTALLED_APPS`` and run ``$ python manage.py migrate``.
You should then see a ``Conditioner`` section with a ``Rule`` child in
Django Admin. Adding a new one should be pretty self-explanatory.
Advanced usage
--------------
Actions and conditions types
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| Both actions and conditions are divided into generic, model generic
and model specific types:
| - generic actions/conditions don't need a set target type (i.e. log a
message on every Monday) - model generic actions/conditions need a set
target type, but work with all available models (i.e. log a message
when selected target type instance was created) - model specific
actions/conditions are implemented with specific model in mind and
area available only when it's selected (i.e. send email to user on
every Monday); they usually operate on specific fields (``user.email``
in previous example)
Adding new actions and/or conditions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
One of the main goals was to make conditioner as flexible as possible
and make adding new actions/conditions as easy as possible.
Creating the action
^^^^^^^^^^^^^^^^^^^
All actions need to inherit from ``BaseAction`` and implement
``run_action()``. Model generic actions should set ``model_specific`` to
``True``, model specific actions should set it to return the needed
model class. If your action is model specific then model instance will
be passed to ``run_action()`` method as ``instance`` named argument.
Making sure that the action is picked up by Django
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You'll need to make sure that your newly created action is picked up by
Django. Assuming that it lives in an ``actions.py`` file inside
``sample_module`` module, your ``sample_module/apps.py`` should look
something like this:
.. code:: python
from django.apps import AppConfig
class SampleModuleAppConfig(AppConfig):
name = 'sample_module'
def ready(self):
# Make sure that all models are imported
from sample_module import actions # noqa
Registering action to Django Admin
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Finally you'll need to hook up your action to the ``Rule`` Django Admin.
You do that by adding it to the list of available inline polymorphic
models:
.. code:: python
from polymorphic.admin import StackedPolymorphicInline
from conditioner.admin import ActionInline
from sample_module.actions import SampleModuleAction
# Register `SampleModuleAction` action to 'conditioner' Django Admin
class SampleModuleActionInline(StackedPolymorphicInline.Child):
model = SampleModuleAction
ActionInline.child_inlines.append(SampleModuleActionInline)
Assuming you put the code above in the ``sample_module/conditioner.py``
file, you'll need to make sure that it's also picked up by Django by
adding ``from sample_module import conditioner`` to your app config
``ready()`` method.
You should now see your custom action in Django Admin.
API
---
There's no proper documentation as of now, but the code is commented and
*should* be pretty straightforward to use.
That said - feel free to open a `GitHub
issue <https://github.com/omni-digital/django-conditioner/issues/new>`__
if anything is unclear.
Tests
-----
Package was tested with the help of ``tox`` on Python 3.4, 3.5 and 3.6
with Django 1.8, 1.9 and 1.10 (see ``tox.ini``).
To run tests yourself you need to run ``tox`` inside the repository:
.. code:: shell
$ tox
Contributions
-------------
Package source code is available at
`GitHub <https://github.com/omni-digital/django-conditioner/>`__.
Feel free to use, ask, fork, star, report bugs, fix them, suggest
enhancements, add functionality and point out any mistakes. Thanks!
New actions and conditions more then welcome but should be first
discussed and agreed upon.
