Doing this enables database-level spatial transformations for the backend. Thus, this utility is useful for adding spatial reference systems not included by default with the backend: >>> from django.contrib.gis.utils import add_srs_entry >>> add_srs_entry(3857) Keyword Arguments: auth_name: This keyword may be customized with the value of the `auth_name` field. Defaults to 'EPSG'. auth_srid: This keyword may be customized with the value of the `auth_srid` field. Defaults to the SRID determined by GDAL. ref_sys_name: For SpatiaLite users only, sets the value of the `ref_sys_name` field. Defaults to the name determined by GDAL. database: The name of the database connection to use; the default is the value of `django.db.DEFAULT_DB_ALIAS` (at the time of this writing, its value is 'default'). �spatial_versionz=The `add_srs_entry` utility only works with spatial backends.z4This utility does not support your database backend.NzMSpatial reference requires an SRID to be compatible with the spatial backend.)�srid� auth_name� auth_srid� proj4textc S s h | ]}|j �qS � )�name)�.0�fr r �O/usr/local/CyberCP/lib/python3.10/site-packages/django/contrib/gis/utils/srs.py� <setcomp>A s z add_srs_entry.<locals>.<setcomp>�srtext� ref_sys_name)r r )r r �hasattr�ops� Exception�features�supports_add_srs_entry�spatial_ref_sys� isinstancer r �proj4�_meta� get_fields�wktr �objects�using�get� DoesNotExist�create) �srsr r r �database� connection� SpatialRefSys�kwargs�srs_field_namesr r r � add_srs_entry s8 �� �r) )r NNN)�django.contrib.gis.gdalr � django.dbr r r) r r r r �<module> s �
