Layers

nodeshot.core.layers is a django-app that enables nodeshot to group nodes in layers.

A layer may have a geographic area and an organization in charge of it.

The area field is required and can be either a polygon or a point. If a polygon is used, its nodes will have to be contained in it and its center will be calculated automatically; otherwise, if a point is used its nodes will be allowed to be located anywhere and the point will be considered its center.

Available settings

nodeshot.core.layers is enabled by default in nodeshot.conf.settings.INSTALLED_APPS.

These are the available customizable settings:

• NODESHOT_LAYERS_HSTORE_SCHEMA
• NODESHOT_API_APPS_ENABLED

NODESHOT_LAYERS_HSTORE_SCHEMA

default: None

custom django-hstore schema to add new fields on the Layer model and API.

The following example will add a category field with a select of 3 choices:

# settings.py

NODESHOT_LAYERS_HSTORE_SCHEMA = [
    {
        'name': 'category',
        'class': 'CharField',
        'kwargs': {
            'max_length': 128,
            'choices': [
                ('category1', 'Category 1'),
                ('category2', 'Category 2'),
                ('category3', 'Category 3')
            ],
            'default': 'category1'
        }
    }
]

Consult the django-hstore documentation for more information (look for schema mode).

NODESHOT_LAYERS_NODES_MINIMUM_DISTANCE
