This issue is resolved in neo4j v4.1 update. But my question is related to neomodel v4.0.1. How do we resolve this issue in neomodel v4.0.1.

My queries: I have models.py as

from neomodel import StructuredNode, StringProperty, UniqueIdProperty()

class Person(StructuredNode):
  person_id = UniqueIdProperty()
  person_name = StringProperty()

when i execute

python manage.py install_labels it works fine with no errors

$ python manage.py install_labels
Setting up indexes and constraints...

Found django_neomodel.DjangoNode
 ! Skipping class django_neomodel.DjangoNode is abstract
Found neo4japp.models.Person
 + Creating unique constraint for person_id on label Person for class neo4japp.models.Person

Finished 2 classes.

But when I create its object like

modiji = Person(person_id='1', person_name='modiji').save()

it gives me this error

CypherSyntaxError: The old parameter syntax `{param}` is no longer supported. Please use `$param` instead (line 1, column 18 (offset: 17)) "CREATE (n:Person {create_params}) RETURN n"

As in OGM we can't manipulate cypher queries - how do I make it work? Please help.

I want to make use of OGM and don't want to hard code cypher queries to make my code effectively using django framework & neomodel.

If not then what is the alternative to neomodel to use OGM queries like the one in ORM so as to ease the database querying stuff?
