Simple, reusable Django application for handling scheduling models for display.
You can use the
schedules app to, as the name says, handle a schedule for
models. You don't have to modify your existing models for this to work, but
you can definitely add a
schedule property if you need to.
The main piece of this app, the
ScheduledItem model, uses a generic
relationship to manage its relationship to any model. To create
a new scheduled item:
ScheduleItem.object.create( published=some_datetime_object, content_object=some_model )
You can use the
objects.available() method to grab all ScheduledItems that
are available---i.e., models that have a
published date that is equal or
before the current time.
You can also filter the type of objects that
available() returns by passing
in an class. For example, to get all of the
Post objects that are available:
Of course, that returns all of the matching
ScheduledItem models, but a more
common case is needing the explicit
Post objects. This provides that functionality
as well via the
return_related() method. For example, you can use:
ScheduledItem.objects.return_related().available(Post) # Or ScheduledItem.objects.available(Post).return_related()
Both are functionality equivalent.
The tests in
d51.django.apps.schedules are complete self-contained. You can
run the tests from within any Django project by executing the standard test
python manage.py test schedules
First, you must initialize a virtual environment:
Next, you need to install Django (if you don't have it installed already),
which is listed in the
requirements.txt file. You can install the necessary
version directly into the virtual environment using the
-E . parameter:
pip install -E . -r requirements.txt
These steps can be run for you with fabric. The
fabfile.py included with
this repository has been tested with 1.0a and may not be backwards compatible.
To initialize using Fabric, you can run:
You must activate the virtual environment if it contains your only copy of Django. You can do this by running:
Your prompt should change to not that you are now running inside the virtual environment. Now you're ready to run the tests.
There are two ways to run the tests. The most straight forward with the output
you've come to expect from a Django test runner is the
You can also run the tests using Fabric, though the output is much more subdued.
A complete copy of Django, along with the tools necessary for virtualenv are installed using this method. Once you are finished testing, you can remove all of the generated files with Fabric by running the following command:
Warning: You must re-run the initialization steps if in order to run the
tests again if you run the
