Django reusable application for content categorization.
Nay, - you say, - all that tags business lacks structuring.
This application is just about structuring your data: build categories hierarchy and link your site entities to those categories.
# Somewhere in views.py
from django.shortcuts import render, get_object_or_404
# Suppose Article model has sitecats.models.ModelWithCategory class mixed in.
from .models import Article
def article_details(self, request, article_id):
"""See, there is nothing special in this view, yet it'll render a page with categories for the article."""
return self.render(request, 'article.html', {'article': get_object_or_404(Article, pk=article_id)})
def article_edit(self, request, article_id):
"""Let's allow this view to render and handle categories editor."""
article = get_object_or_404(Article, pk=article_id)
# Now we enable category editor for an article, and allow users
# to add subcategories to `language`, and `os` categories
# (suppose we created them beforehand with Admin contrib),
# and link this article to them.
article.enable_category_lists_editor(
request,
editor_init_kwargs={'allow_new': True},
additional_parents_aliases=['language', 'os']
)
form = ... # Your usual Article edit handling code will be here.
return render(request, 'article.html', {'article': article, 'form': form})Template coding basically boils down to sitecats_categories template tags usage:
<!-- The same html is just fine for demonstration purposes for both our views.
Do not forget to load `sitecats` template tags library. -->
{% extends "base.html" %}
{% load sitecats %}
{% block contents %}
<!-- Some additional functionality (e.g. categories cloud rendering,
editor enhancements) will require JS. -->
<script src="{{ STATIC_URL }}js/sitecats/sitecats.min.js"></script>
<h1>{{ article.title }}</h1>
<div id="article_categories">
{% sitecats_categories from article %} <!-- And that's it. -->
</div>
<!-- Form code goes somewhere here. -->
{% endblock %}Read the docs, sitecats can do more.
