37135	"LayerMapping utility seems unable to import PointFields with ""unique"" keyword parameter"	Agnès Haasser		"Hello,

I'm trying to use LayerMapping in order to import Geographic Data in my database, in ""update"" mode. That is, I use ""unique"" parameter to check if LayerMapping should update existing entries or create new ones:


{{{
lm = LayerMapping(
            target_class,
            path_to_my_shp_file,
            my_mapping,
            unique=tuple_of_django_fields,
        )
lm.save(strict=True, verbose=True)
}}}


When target_class has a geometry of type PointField, I get an error:



{{{
'Point' object is not iterable
Traceback (most recent call last):
  File ""file_on_disk/sia/gis_import/views.py"", line 12, in launch_import
    databatch.import_geographic_data()
  File ""file_on_disk/sia/gis_import/models.py"", line 66, in import_geographic_data
    lm.save(strict=True, verbose=True)
  File ""file_on_disk/venv/lib/python3.11/site-packages/django/contrib/gis/utils/layermapping.py"", line 728, in save
    _save()
  File ""file_on_disk/venv/lib/python3.11/site-packages/django/contrib/gis/utils/layermapping.py"", line 653, in _save
    for g in new:
TypeError: 'Point' object is not iterable
}}}

I'm using Django 5.2 so I have an older version of layermapping  but it seems the bug is still here in present source code (6.2 is not out yet as I write this ticket):
