How can I update a relationship property in py2neo or cypher after it has been initially set? In my inventory tracking system, when an item is checked out, the "status" property in the relationship is set to "True". However, I'd like to change this property to "False" once the item is returned or checked back in. This will help me keep track of items and prevent them from being checked out multiple times.
Below is the code I am currently using to create the relationship for a checkout transaction:
def check_out(self, barcode):
emp = self
item = barcode
id = str(uuid.uuid4())
timestamp = int(datetime.now().strftime("%s"))
date = datetime.now().strftime("%F")
status=True
rel = Relationship(emp, "CHECKED_OUT", item, id=id, timestamp=timestamp, date=date, status=status)
if not(graph.create_unique(rel)):
return True
else:
return False
I have gone through the py2neo API documentation but haven't found a solution. If modifying the relationship is not the right approach, do you have any suggestions for a better method?
