Neo4J Django neomodel not showing nodes in the explorer

Question

I'm new to Graph database and using Neo4j database with neomodel library in Django application.

The settings are defined as

NEOMODEL_NEO4J_BOLT_URL = os.environ.get('NEO4J_BOLT_URL')
NEOMODEL_SIGNALS = True
NEOMODEL_FORCE_TIMEZONE = False
NEOMODEL_ENCRYPTED_CONNECTION = True
NEOMODEL_MAX_POOL_SIZE = 50

and the models.py file has the following model

class Person(StructuredNode):
    SEXES = {
        'm': 'Male',
        'f': 'Female',
    }

    id = properties.UniqueIdProperty()
    first_name = properties.StringProperty(unique_index=True, required=True, max_length=100)

    gender = properties.StringProperty(choices=SEXES, required=True)

In Django shell python manage.py shell, creating a node as

>>> from family_tree.models import Person
>>> person = Person(first_name='Anuj', gender='m')
>>> person.save()
<Person: {'id': '572d0b8ff3a8402ba58c4a03cace78ba', 'first_name': 'Anuj', 'middle_name': None, 'last_name': None, 'gender': 'm', 'date_of_birth': None, 'date_of_death': None, 'created': datetime.datetime(2023, 6, 24, 7, 44, 26, 223871, tzinfo=<UTC>)}>

But the database explorer has no nodes in it.

Also refreshing node gives DoesNotExist exception

>>> person.refresh()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/usr/local/lib/python3.9/site-packages/neomodel/core.py", line 616, in refresh
    raise self.__class__.DoesNotExist("Can't refresh non existent node")
neomodel.core.PersonDoesNotExist: (PersonDoesNotExist(...), "Can't refresh non existent node")

The problem is setting id in your Person class. This is a special field that is set internally by neomodel.

According to https://neomodel.readthedocs.io/en/latest/properties.html

All nodes in neo4j have an internal id (accessible by the ‘id’ property in neomodel) however these should not be used by an application. Neomodel provides the UniqueIdProperty to generate unique identifiers for nodes (with a unique index)

If you change your code to use uid (or any other field name) instead of id it will work.
