Django Locations Tree

Simple application for location field as TreeForeignKey (see django-mptt) with form field.

Usage

# settings.py
INSTALLED_APPS += ('mptt', 'locationstree')

# models.py
class Place(models.Model):
  location = TreeForeignKey('locationstree.Location')

# forms.py
class PlaceForm(models.Model):
  location = JustLeafsLocationField(queryset=Location.objects.all())

Context Processor

There is a context processor that sets Locations.objects.all() to context with the variable name by default locations:

# settings.py
CONTEXT_PROCESSORS += ('locationstree.context_processors.locations',)

The variable name is configurable via settings variable:

# settings.py
LOCATIONSTREE_CONTEXT_VARIABLE_NAME = 'lugares_comunes'

It uses cache with the key name locationstree.locations and a TTL of 1 week configurable via settings variable:

# settings.py
LOCATIONSTREE_CACHE_TTL = 60 * 60 * 24 # 1 day
