Django Publishable
What is Django-Publishable?
Django library that add to your models the draft/publish features.
Instalation
$ pip install django-publishable
Quick start
- Add "publishable" to your INSTALLED_APPS setting like this::
INSTALLED_APPS = [ ... 'publishable', ]
- Run
python manage.py migrate
to create the publishable models. - Try to replicate this with your models:
from django.db import models from publishable.models import Publishable, Publisher # A Publisher is responsible for triggering # the publish all drafts that he contains class User(Publisher): pass # Overdide the Publishable to implement the logic # of broadcast_need_to_published class MyPublishable(Publishable): class Meta: abstract = True def broadcast_need_to_published(self): """ This function will return a Draft instance then it's up to you select your Publisher and add it to it's draft """ draft = super(MyPublishable, self).broadcast_need_to_published() chatbot, _ = User.objects.get_or_create(pk=1) chatbot.add_draft(draft) # After setting up your Publishable # then inherit from it into the model that you need to receie # draft/publish features class Article(MyPublishable): title = models.CharField(max_length=255) content = models.TextField() comments = models.ManyToManyField('Comment', related_name='comments') highlighted_comment = models.ForeignKey('Comment', related_name='highlighted_comment', null=True) class Comment(MyPublishable): content = models.CharField(max_length=255)
- By default now all your model will store changes into the draft
# Add changes and publish one model >>> a = Article.objects.create() >>> a.title = "foo" >>> a.publish() >>> a.published.title foo # Let's add changes and publish using a publisher >>> a.title = "boo" >>> a.save() >>> a.published.title foo >>> user = User.objects.get(pk=1) >>> user.publish() # You can track the status of the publishing process >>> user.publishing_status PUBLISHED
Using the Context Manager
In order to keep your code clean and avoid replication of code by doing article.published
all the time, you can use the PublishedContextManager
. Every operation that you do inside the with
will target the published version of the model. But be carful do not do any changes to the published
, you're only supposed to read data, inserting the data should target the draft
.
>>> from publishable.context_managers import PublishedContextManager
>>> a = Article.objects.create(title="foo")
>>> a.publish()
>>> a.title = "boo"
>>> a.save()
>>> with PublishedContextManager():
print(a.title)
foo
>>> print(a.title)
boo
