Project Description

django_trees

Simple way to create, persist and manipulate reliable tree structures using Django models.

Installation

pip install django-trees

API Usage

Create Model

To create a model extend AbstractNode and add desired fields.

from django.db import models
from django_trees.models import AbstractNode

class Folder(AbstractNode):
    name = models.CharField(max_length=10)

Create Tree Nodes

To create a tree node, there is nothing different than creating a normal Django model other than you may specify a parent node.

root = Folder.objects.create(name="Root")
documents = Folder.objects.create(name="Documents", parent=root)
downloads = Folder.objects.create(name="Downloads", parent=root)
projects = Folder.objects.create(name="Projects", parent=documents)

Get Node Descendants

To retrieve all of the descendants of a node (including children, grandchildren, great grandchildren, etc) use the get_descendants method. This method will return a flat list of node objects.

root.get_descendants()

Get Node Ancestors

To retrieve all of the ancestors of a node (including parents, grandparents, great grandparents, etc) use the get_ancestors method. This method will return a flat list of node objects.

projects.get_ancestors()

Get Node Children

To retrieve all immediate children of the current node use the get_children method. This method will return a flat list of node objects.

projects.get_children()

Move Node

To move a node to a different position in the tree use the move method passing the new parent node as an argument.

projects.move(root)

Bifurcate Node

To create a separate tree from a branch of an existing tree use the bifurcate method. The node object will be removed from the previous tree and it along with its descendants will now be in a new tree.

projects.bifurcate()

Get ASCII Tree

To get an ascii representation of the tree structure use the get_ascii_tree method.

projects.get_ascii_tree()
