Issue in custom init while using get

Since neomodel does not have any auto incrementing id, I decided to create an IntegerField called id and set its value to current count of that node class + 1. For this I overwrote the init class as in given example:

class NodeClass:
     id = neomodel.IntegerProperty()
     # more fields ...
     def __init__(self,*args,**kwargs):
          if id not in kwargs: 
              kwargs["id"] = len(NodeClass.nodes) + 1
          super(NodeClass,self).__init__(self,*args,**kwargs)

When I create a new instance of this NodeClass, everything is fine ( id is also set correctly). But when I try to use the get method as

NodeClass.nodes.get(id=123)

I get the following exception:

super(type, obj): obj must be an instance or subtype of type

P.S provided the code sample so just to make sure that I am not doing anything wrong instead of neomodel

@siddharthm just as a note I’d recommend utilizing something like python’s UUID package to generate unique identifiers for nodes, it’s a bit more scalable and doesn’t run the risk of race conditions under load which this implementation may run into if a node hasn’t been written to the database yet and the init method gets called. This will also cause a lot less querying to occur. To create your id you would do something along the lines of

from uuid import uuid1

id = uuid1()

On another note if you do it this way you don’t have to override init and can just set the function as the default parameter so it would look something like:

class NodeClass:
     id = neomodel.StringProperty(default=uuid1, unique_index=True)

On the exception I’ll have to investigate further.

id is also now used by neomodel v3 so i’d avoid using it as a property name
