django-treenav 2.0.0

Features

• Generic functionality with multiple URL specifications: get_absolute_url(), reverse(), or raw URLs

• Packaged with templates to render the tree hierarchy with nested <ul>’s, but can easily be overridden with custom templates

• Easily customize each item’s template or fall back to a default menuitem.html

• Useful CSS classes for flexible UI customization

• Automatically sets “active” on item and item’s parents if PATH_INFO is equal to item.href

• Efficient: minimizes database access with django-mptt functionality

• Caches the tree so that repeated page views do not hit the database.

• Simple links in the MenuItem list view for refreshing the cache and href from the database.

Requirements

• django >= 2.2

• django-mptt >= 0.11.0

Using the demo

For a quick demo, follow these steps:

1. Create a virtualenv. (This example uses mkvirtualenv, but there are many other ways to do it):

   $ mkvirtualenv django-treenav

2. Check out the code and install the requirements:

   (django-treenav)$ git clone git://github.com/caktus/django-treenav.git
   (django-treenav)$ cd django-treenav/
   (django-treenav)~/django-treenav/$ pip install -Ur dev-requirements.txt

3. Run migrations and create a superuser so you can login to the Django admin:

   (django-treenav)~/django-treenav$ python manage.py migrate
   (django-treenav)~/django-treenav$ python manage.py createsuperuser

4. Run the server:

   (django-treenav)~/django-treenav$ python manage.py runserver

5. Visit http://localhost:8000/ in your browser and follow the instructions.

Installation

1. Install the app with pip:

   pip install django-treenav

2. Add to your INSTALLED_APPS and run migrate:

   INSTALLED_APPS = (
       ...,
       'mptt',
       'treenav',
   )

3. Include these context processors:

   TEMPLATES = [
     {
       'OPTIONS': {
         'context_processors': [
           "django.template.context_processors.request",
           "treenav.context_processors.treenav_active",
         ],
       },
     },
   ]

4. Add these urls:

   urlpatterns = [
       url(r'^treenav/', include('treenav.urls')),
   ]

Maintainer Information

We use Github Actions to lint (using pre-commit, black, isort, and flake8), test (using tox and tox-gh-actions), calculate coverage (using coverage), and build documentation (using sphinx).

We have a local script to do these actions locally, named maintain.sh:

$ ./maintain.sh

A Github Action workflow also builds and pushes a new package to PyPI whenever a new Release is created in Github. This uses a project-specific PyPI token, as described in the PyPI documentation here. That token has been saved in the PYPI_PASSWORD settings for this repo, but has not been saved anywhere else so if it is needed for any reason, the current one should be deleted and a new one generated.

As always, be sure to bump the version in treenav/__init__.py before creating a Release, so that the proper version gets pushed to PyPI.
