This Django app manages navigations trees with simple features. It is highly inspired by django-treenav and django-sitetree. It offers a lighter version to allow easy customisation.

The trees structure is using mptt. Each item offer various options to generate the url, restrict access given user status and permissions, classes and behaviours.

It is strongly recommanded to install this theme from GIT with PIP onto you project virtualenv.

From PyPi

From Github

https://github.com/django-mojo/mojo-navigation#egg=mojo-navigation

This application works with django mptt module in order to display the trees. It is highly recommended to add it in the INSTALLED_APPS.

INSTALLED_APPS = (
    ...
    'django_mptt'
    ...
)

If you want to use the default model and admin, also install the module itself.

INSTALLED_APPS = (
    ...
    'mojo.navigation'
    ...
)

Then install your model with

python manage.py syncdb

In case you are using South, you can alternatively do:

python manage.py migrate mojo.navigation

There are 2 main managers to help sortting and filtering the menu items.

You can get all items of a specific tree by passing its slug in the for_tree manager, for exemple:

tree_items = Item.objects.for_slug('slug_exemple')

As we are using permissions for items. You can filter items for a specific user to retrieve all the items he has access to by passing its object in the for_user manager, for exemple:

tree_items = Item.objects.for_user(request.user)

You can limit the number of tree levels of trees. For exemple, some menus can be one or two levels only. In such case its useless to allow the the user to add more.

In order to limit the number of levels you need to create a custom admin class inheriting from mojo.navigation.admin.ItemAdmin and add a level_limit attribute with the desired value.

For exemple, this will limit the tree to two levels:

from mojo.navigation.admin import ItemAdmin

class CustomItemAdmin(ItemAdmin):
    level_limit = 1
