Return the created FeatureTypeElement record(s)

ValueError: if self.remote_content is null
- save(*args, **kwargs)
Custom save function to handle activate process for the feature type and his related service. If the given feature type shall be active, the feature type it self and the related
registry.models.service.Servicewill be updated withis_active=True. If the given feature type shall be inactive only the feature type it self will be updated withis_active=False.

- bbox
Return the bbox of this layer based on the inheritance from other layers as requested in the ogc specs.
Note
excerpt from ogc specs
ogc wms 1.1.1: Every Layer shall have exactly one <LatLonBoundingBox> element that is either stated explicitly or inherited from a parent Layer. (see section 7.1.4.5.6)
ogc wms 1.3.0: Every named Layer shall have exactly one <EX_GeographicBoundingBox> element that is either stated explicitly or inherited from a parent Layer. (see section 7.2.4.6.6)
- Returns
self.bbox_lat_lon if not None else bbox_lat_lon from the first ancestors where bbox_lat_lon is not None
- Return type
django.contrib.gis.geos.polygon
- dimensions
Return all dimensions of this layer, based on the inheritance from other layers as requested in the ogc specs.
Note
excerpt from ogc specs
ogc wms 1.1.1: Dimension declarations are inherited from parent Layers. Any new Dimension declarations in the child are added to the list inherited from the parent. A child shall not redefine a Dimension with the same name attribute as one that was inherited. Extent declarations are inherited from parent Layers. Any Extent declarations in the child with the same name attribute as one inherited from the parent replaces the value declared by the parent. A Layer shall not declare an Extent unless a Dimension with the same name has been declared or inherited earlier in the Capabilities XML.
ogc wms 1.3.0: Dimension declarations are inherited from parent Layers. Any new Dimension declaration in the child with the same name attribute as one inherited from the parent replaces the value declared by the parent.
- Returns
all dimensions of this layer
- Return type
django.db.models.query.QuerySet
- inherit_scale_max
Return the scale min value of this layer based on the inheritance from other layers as requested in the ogc specs.
Note
excerpt from ogc specs
ogc wms 1.1.1: ScaleHint is inherited by child Layers. A ScaleHint declaration in the child replaces the any declaration inherited from the parent. (see section 7.1.4.5.8 ScaleHint)
- Returns
self.scale_max if not None else scale_max from the first ancestors where scale_max is not None
- Return type
django.contrib.gis.geos.polygon
- inherit_scale_min
Return the scale min value of this layer based on the inheritance from other layers as requested in the ogc specs.
Note

ogc wms 1.1.1: ScaleHint is inherited by child Layers. A ScaleHint declaration in the child replaces the any declaration inherited from the parent. (see section 7.1.4.5.8 ScaleHint)
- Returns
self.scale_min if not None else scale_min from the first ancestors where scale_min is not None
- Return type
django.contrib.gis.geos.polygon
- save(*args, **kwargs)
Custom save function to handle activate process for the layer, all his descendants and his related service. If the given layer shall be active, the complete family (
mptt.models.MPTTModel.get_family()) of this layer and the relatedregistry.models.service.Servicewill be updated withìs_active=True. If the given layer shall be inactive, all descendants (mptt.models.MPTTModel.get_descendants()) of this layer will be updated withis_active=False.
- supported_reference_systems
Return all supported reference systems for this layer, based on the inheritance from other layers as requested in the ogc specs.
Note
excerpt from ogc specs
ogc wms 1.1.1: Every Layer shall have at least one <SRS> element that is either stated explicitly or inherited from a parent Layer (see section 7.1.4.5.5).
ogc wms 1.3.0: Every Layer is available in one or more layer coordinate reference systems. 6.7.3 discusses the Layer CRS. In order to indicate which Layer CRSs are available, every named Layer shall have at least one <CRS> element that is either stated explicitly or inherited from a parent Layer.
- Returns
all supported reference systems
registry.models.metadata.ReferenceSystemfor this layer- Return type
django.db.models.query.QuerySet
- class registry.models.service.OgcService(*args, **kwargs)
Abstract Service model to store OGC service.
- exception DoesNotExist
- exception MultipleObjectsReturned
- save(*args, **kwargs)
Save the current instance. Override this in a subclass if you want to control the saving process.
The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.
- class registry.models.service.OperationUrl(*args, **kwargs)
Concrete model class to store operation urls for registered services
With that urls we can perform all needed request to a given service.
- exception DoesNotExist
- exception MultipleObjectsReturned
- class registry.models.service.ServiceElement(*args, **kwargs)
Abstract model class to generalize some fields and functions for layers and feature types
