max_geom_collectionsLink to this heading#

Field.max_geom_collectionsLink to this definition#

The maximum number of geometry collections the field accepts before refusing to parse the input and raising a ValidationError. This guards against crashes in the underlying GEOS library when parsing deeply nested GEOMETRYCOLLECTION input. It defaults to 198.

The limit is applied differently depending on the input format: for well-known text (WKT) it bounds the nesting depth, while for well-known binary (WKB and hex-encoded WKB) it bounds the total number of geometry collections (both breadth and depth). As a result, the same value may accept a wide, shallow collection as WKT but reject it as WKB. For GeoJSON, the limit is not applied at all, since GDAL parses that input type instead.

Increase this value (or set to None) only if you must accept legitimately deep geometries, since doing so reduces protection against fatal errors.

BaseGeometryWidget.base_layerLink to this definition#

A string that specifies the identifier for the default base map layer to be used by the corresponding JavaScript map widget. It is passed as part of the widget options when rendering, allowing the MapWidget to determine which map tile provider or base layer to initialize (default is None).

BasegeometryWidget

class BaseGeometryWidgetLink to this definition#

This is an abstract base widget containing the logic needed by subclasses. You cannot directly use this widget for a geometry field. Note that the rendering of GeoDjango widgets is based on a base layer name, identified by the base_layer class attribute.

OpenLayersWidget

class OpenLayersWidgetLink to this definition#

This is the default widget used by all GeoDjango form fields. Attributes are:

OpenLayersWidget and OSMWidget include the ol.js and ol.css files hosted on the cdn.jsdelivr.net content-delivery network. These files can be overridden by subclassing the widget and setting the js and css properties of the inner Media class (see Sócmhainní mar shainiú statach).

OsmWidget

class OSMWidgetLink to this definition#

This widget specialized OpenLayersWidget and uses an OpenStreetMap base layer to display geographic objects on. Attributes are:

Customizing the base layer used in OpenLayers-based widgetsLink to this heading#

To customize the base layer displayed in OpenLayers-based geometry widgets, define a new layer builder in a custom JavaScript file. For example:

 MapWidget.layerBuilder.custom_layer_name = function () {
     // Return an OpenLayers layer instance.
     return new ol.layer.Tile({source: new ol.source.<ChosenSource>()});
 };

Then, subclass a standard geometry widget and set the base_layer:

from django.contrib.gis.forms.widgets import OpenLayersWidget


class YourCustomWidget(OpenLayersWidget):
    base_layer = "custom_layer_name"

    class Media:
        js = ["path-to-file.js"]
